1、技术目标
了解并创建Security框架所需数据表
为项目添加Spring Security框架
掌握Security框架配置
应用Security框架为项目的CRUD操作绑定权限
注意：本文所用项目为"影片管理"，参看
http://hotstrong.iteye.com/blog/1156785
2、权限管理需求描述
为系统中的每个操作定义权限，如定义4个权限：
1）超级权限，可以使用所有操作
2）添加影片权限
3）修改影片权限
4）删除影片权限
为系统设置管理员帐号、密码
为系统创建权限组，每个权限组可以配置多个操作权限，如创建2个权限组：
1）"Administrator"权限组，具有超级权限
2）"影片维护"权限组，具有添加影片、修改影片权限
可将管理员加入权限组，管理员登录后具备权限组所对应操作权限
管理员可不属于某权限组，可为管理员直接分配权限
3、使用准备
3.1）在数据库中创建6张表
t_admin 管理员帐号表
t_role权限表
t_group 权限组表
t_group_role权限组对应权限表
t_group_user管理员所属权限组表
t_user_role管理员对应权限表
建表SQL语句如下：
Sql代码

CREATE TABLE `t_group_role` (
`id` bigint(20) unsigned NOT NULL AUTO_INCREMENT,
`groupid` bigint(20) unsigned NOT NULL,
`roleid` bigint(20) unsigned NOT NULL,
PRIMARY KEY (`id`),
UNIQUE KEY `groupid2` (`groupid`,`roleid`),
KEY `roleid` (`roleid`),
CONSTRAINT `t_group_role_ibfk_1` FOREIGN KEY (`groupid`) REFERENCES `t_group` (`id`),
CONSTRAINT `t_group_role_ibfk_2` FOREIGN KEY (`roleid`) REFERENCES `t_role` (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=83 DEFAULT CHARSET=utf8;
-- ----------------------------
-- 加入权限组与权限的对应关系
-- ----------------------------
INSERT INTO `t_group_role` VALUES ('1', '1', '1');
INSERT INTO `t_group_role` VALUES ('2', '2', '2');
INSERT INTO `t_group_role` VALUES ('4', '2', '4');
-- ----------------------------
-- 创建管理员所属权限组表t_group_user
-- ----------------------------
CREATE TABLE `t_group_user` (
`id` bigint(20) unsigned NOT NULL AUTO_INCREMENT,
`userid` bigint(20) unsigned NOT NULL,

-- ----------------------------
-- 将管理员加入权限组
-- ----------------------------
INSERT INTO `t_group_user` VALUES ('1', '1', '1');
INSERT INTO `t_group_user` VALUES ('2', '4', '2');
-- ----------------------------
-- 创建管理员对应权限表t_user_role

-- ----------------------------
CREATE TABLE `t_user_role` (
`id` bigint(20) unsigned NOT NULL AUTO_INCREMENT,
`userid` bigint(20) unsigned NOT NULL,
`roleid` bigint(20) unsigned NOT NULL,
PRIMARY KEY (`id`),

CONSTRAINT `t_user_role_ibfk_1` FOREIGN KEY (`userid`) REFERENCES `t_admin` (`id`),
CONSTRAINT `t_user_role_ibfk_2` FOREIGN KEY (`roleid`) REFERENCES `t_role` (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=5 DEFAULT CHARSET=utf8;
3.2）在项目中新增如下jar包(security框架所需jar包)：
注意：以下jar包本文已提供下载
spring-security-config-3.1.0.RC2.jar
spring-security-core-3.1.0.RC2.jar
spring-security-taglibs-3.1.0.RC2.jar
spring-security-web-3.1.0.RC2.jar
3.3）创建如下包，放置登录验证过滤器代码：
com.xxx.security
3.4）在src下创建Spring配置文件applicationContext-security.xml，内容如下：
Xml代码
<?xml version="1.0" encoding="UTF-8"?>
<beans:beans xmlns="http://www.springframework.org/schema/security"
xmlns:b="http://www.springframework.org/schema/beans" xmlns:beans="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/security http://www.springframework.org/schema/security/spring-security-3.1.xsd">
<!-- 这里进行配置 -->
</beans:beans>
3.5）在web.xml中加入security配置，如下：
Xml代码
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5"
xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"> <welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/applicationContext-*.xml,classpath*:applicationContext-*.xml</param-value>
</context-param>
<!-- 配置Spring Security -->
<filter>
<filter-name>springSecurityFilterChain</filter-name>
<filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
</filter>

<url-pattern>/*</url-pattern>
</filter-mapping>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
</web-app>
4、站点根路径下创建登录页面login.jsp，代码如下：
Html代码
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<%@ taglib prefix="s" uri="/struts-tags"%>
<%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path;
%>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>后台登录</title>
</head>
<body onload="document.loginForm.j_username.focus();">
<!-- 登录表单 -->
<form name="loginForm" action="<c:url value='/j_spring_security_check'/>" method="post">
<!-- 登录失败后，显示之前的登录名 -->
用户名：<input type='text' name='j_username' class="txtinput"
value='<c:if test="${not empty param.login_error}" >
<c:out value="${SPRING_SECURITY_LAST_USERNAME}"/></c:if>' />
<br />
密码：<input type='password' name='j_password' class="txtinput" />
<br />
<input type="checkbox" name="_spring_security_remember_me" />
保存登录信息
<input name="submit" type="submit" value="提交" />
<input name="reset" type="reset" value="重置" />
</form>
<br />
<!-- 显示登录失败原因 -->
<c:if test="${not empty param.error}">
<font color="red"> 登录失败<br />
<br />
原因: <c:out value="${SPRING_SECURITY_LAST_EXCEPTION.message}" />. </font>
</c:if>
</body>
</html>
5、站点根路径下创建注销页面loggedout.jsp，代码如下：
Html代码
<%@page session="false" %>
<%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ page pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path;
%>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="content-type" content="text/html; charset=UTF-8" />
<title>登出</title>
</head>
<body>
你已经退出。
<a href="<c:url value='/login.jsp'/>">点击这里登录</a>
</body>
</html>
6、站点根路径下创建HttpSession超时提示页面timeout.jsp，代码如下：
Html代码
<%@page session="false" %>
<%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ page pageEncoding="UTF-8" contentType="text/html; charset=UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path;
%>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>用户失效</title>
</head>
<body>
你的登录已经失效，请重新登录。
<br />
<a href="<c:url value='/login.jsp'/>" >
点击这里登录</a>
</body>
</html>
7、在com.xxx.security包下创建登录验证过滤器，该过滤器可用于在管理员登录时进行日志记录等相关操作，包括两个类：
LoginUsernamePasswordAuthenticationFilter
LoginSuccessHandler
7.1）LoginUsernamePasswordAuthenticationFilter代码如下：
Java代码
package com.xxx.security;
import org.springframework.security.web.authentication.UsernamePasswordAuthenticationFilter;
public class LoginUsernamePasswordAuthenticationFilter extends
UsernamePasswordAuthenticationFilter {
}
7.2）LoginSuccessHandler代码如下：
Java代码
package com.xxx.security;
import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.security.core.Authentication;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.web.authentication.SavedRequestAwareAuthenticationSuccessHandler;
/**
* 处理管理员登录日志
*
*/
public class LoginSuccessHandler extends SavedRequestAwareAuthenticationSuccessHandler{
@Override
public void onAuthenticationSuccess(HttpServletRequest request,
HttpServletResponse response, Authentication authentication) throws IOException,
ServletException {
UserDetails userDetails = (UserDetails)authentication.getPrincipal();
//输出登录提示信息
System.out.println("管理员 " + userDetails.getUsername() + " 登录");
super.onAuthenticationSuccess(request, response, authentication);
}
}
8、在applicationContext-security.xml中加入权限管理配置，如下：
Xml代码
<?xml version="1.0" encoding="UTF-8"?>
<beans:beans xmlns="http://www.springframework.org/schema/security"
xmlns:b="http://www.springframework.org/schema/beans" xmlns:beans="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/security http://www.springframework.org/schema/security/spring-security-3.1.xsd">
<http >
<!-- 不拦截login.jsp -->
<intercept-url pattern="/login.jsp*" access="IS_AUTHENTICATED_ANONYMOUSLY" />
<!--仅拦截到manager下面的内容，具备access对应权限的-->
<intercept-url pattern="/manager/**" access="ROLE_ADMIN,ROLE_UPDATE_FILM,ROLE_DELETE_FILM,ROLE_ADD_FILM" />
<!-- 设置登录过滤器 -->
<custom-filter before="FORM_LOGIN_FILTER" ref="authenticationProcessingFilter" />
<!-- 登录表单设置 -->
<form-login login-page="/login.jsp"
default-target-url="/manager/films.jsp"
authentication-failure-url="/login.jsp?error=true" />
<!-- 登出操作后跳转到该页面 -->
<logout logout-success-url="/loggedout.jsp"
delete-cookies="JSESSIONID" />
<remember-me />
<!-- SESSION超时后跳转到该页面 -->
<session-management invalid-session-url="/timeout.jsp">
</session-management>
</http>
<authentication-manager alias="authenticationManager">
<authentication-provider>
<!--
直接使用SQL语句查询登录帐号对应权限，
users-by-username-query：查询登录用户是否存在
authorities-by-username-query：查询登录用户权限(登录用户可以不属于任何组，从t_user_role表中获取权限)
group-authorities-by-username-query：查询登录用户所在组的权限
-->
<jdbc-user-service data-source-ref="dataSource"
group-authorities-by-username-query="SELECT g.id,g.groupname,role.role
FROM t_group AS g
LEFT OUTER JOIN t_group_role AS grouprole ON (g.id = grouprole.groupid)
LEFT OUTER JOIN t_role AS role ON (role.id = grouprole.roleid)
LEFT OUTER JOIN t_group_user AS groupuser on (g.id = groupuser.groupid)
LEFT OUTER JOIN t_admin ON (t_admin.id = groupuser.userid)
WHERE t_admin.nickname = ?"
users-by-username-query="SELECT t_admin.nickname AS username,t_admin.passwd as password,'true' AS enabled

LEFT OUTER JOIN t_user_role AS userrole ON(t_admin.id = userrole.userid)
LEFT OUTER JOIN t_role AS role ON (userrole.roleid = role.id)
WHERE t_admin.nickname = ?" />
</authentication-provider>
</authentication-manager>
<!-- 自定义消息 -->
<b:bean id="messageSource"
class="org.springframework.context.support.ReloadableResourceBundleMessageSource">
<b:property name="basename"
value="classpath:org/springframework/security/messages" />
</b:bean>
<!-- 定制登录过滤器 -->
<beans:bean id="loginSuccessHandler" class="com.xxx.security.LoginSuccessHandler">
<b:property name="defaultTargetUrl">
<!-- 登录成功后转发到该页面 -->
<b:value>/manager/films.jsp</b:value>
</b:property>
</beans:bean>
<beans:bean id="authenticationProcessingFilter" class="com.xxx.security.LoginUsernamePasswordAuthenticationFilter">
<beans:property name="authenticationSuccessHandler" ref="loginSuccessHandler"></beans:property>
<beans:property name="authenticationFailureHandler" ref="authenticationFailureHandler"></beans:property>
<beans:property name="authenticationManager" ref="authenticationManager"></beans:property>
</beans:bean>
<beans:bean id="authenticationFailureHandler" class="org.springframework.security.web.authentication.SimpleUrlAuthenticationFailureHandler">
<beans:property name="defaultFailureUrl">
<!-- 登录失败后转发到该页面 -->
<beans:value>/login.jsp?error=true</beans:value>
</beans:property>
</beans:bean>
</beans:beans>
9、为影片页面films.jsp定制操作权限，定制后，不同的帐号登录会看到不同的操作，
比如，帐号"admin"属于权限组"Administrator"，具备权限"ROLE_ADMIN"，登录后
可以看到所有操作，帐号"test"属于权限组"影片维护"，具备权限"ROLE_UPDATE_FILM"
和"ROLE_ADD_FILM"，登录后只能看到"添加影片信息"和"修改"操作
films.jsp页面权限分布图：
films.jsp代码如下：
Html代码
<%@ page language="java" contentType="text/html; charset=utf-8"
pageEncoding="utf-8" %>
<%@taglib uri="/struts-tags" prefix="s" %>
<%@ taglib prefix="security"
uri="http://www.springframework.org/security/tags"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>信息操作</title>
</head>
<body>
<s:form action="/film/findFilm" method="post">
<s:submit value=" 获取所有影片信息 "></s:submit>
</s:form>
<!-- 添加影片操作，登录帐号具备ROLE_ADMIN权限或者ROLE_ADD_FILM权限可以执行 -->
<security:authorize ifAnyGranted="ROLE_ADMIN,ROLE_ADD_FILM">
<a href="<%=basePath %>manager/insertFilm.jsp">添加影片信息</a><br />
</security:authorize>
<s:if test="filmList != null">
<table border="1" width="40%">
<tr>
<th>序号</th><th>影片名</th><th>操作</th>
</tr>
<%-- 遍历影片信息 --%>
<s:iterator var="film" value="filmList" status="st">
<tr>
<td><s:property value="#st.index+1" /></td>
<td><s:property value="fname" /></td>
<td>
<!-- 修改影片操作，登录帐号具备ROLE_ADMIN权限或者ROLE_UPDATE_FILM权限可以执行 -->
<security:authorize ifAnyGranted="ROLE_ADMIN,ROLE_UPDATE_FILM">
<s:url id="detailUrl" value="/film/detailFilm">
<s:param name="id" value="%{id}"/>
</s:url>
<s:a href="%{detailUrl}">[修改]</s:a>
</security:authorize>
<!-- 删除影片操作，登录帐号具备ROLE_ADMIN权限或者ROLE_DELETE_FILM权限可以执行 -->
<security:authorize ifAnyGranted="ROLE_ADMIN,ROLE_DELETE_FILM">
<s:url id="deleteUrl" value="/film/deleteFilm">
<s:param name="id" value="%{id}"/>
</s:url>
<s:a href="%{deleteUrl}">[删除]</s:a>
</security:authorize>
</td>
</tr>
</s:iterator>
</table>
</s:if>

4、站点根路径下创建登录页面login.jsp，代码如下：
Html代码
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<%@ taglib prefix="s" uri="/struts-tags"%>
<%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path;
%>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>后台登录</title>
</head>
<body onload="document.loginForm.j_username.focus();">
<!-- 登录表单 -->
<form name="loginForm" action="<c:url value='/j_spring_security_check'/>" method="post">
<!-- 登录失败后，显示之前的登录名 -->
用户名：<input type='text' name='j_username' class="txtinput"
value='<c:if test="${not empty param.login_error}" >
<c:out value="${SPRING_SECURITY_LAST_USERNAME}"/></c:if>' />
<br />
密码：<input type='password' name='j_password' class="txtinput" />
<br />
<input type="checkbox" name="_spring_security_remember_me" />
保存登录信息
<input name="submit" type="submit" value="提交" />
<input name="reset" type="reset" value="重置" />
</form>
<br />
<!-- 显示登录失败原因 -->
<c:if test="${not empty param.error}">
<font color="red"> 登录失败<br />
<br />
原因: <c:out value="${SPRING_SECURITY_LAST_EXCEPTION.message}" />. </font>
</c:if>
</body>
</html>
5、站点根路径下创建注销页面loggedout.jsp，代码如下：
Html代码
<%@page session="false" %>
<%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ page pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path;
%>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="content-type" content="text/html; charset=UTF-8" />
<title>登出</title>
</head>
<body>
你已经退出。
<a href="<c:url value='/login.jsp'/>">点击这里登录</a>
</body>
</html>
6、站点根路径下创建HttpSession超时提示页面timeout.jsp，代码如下：
Html代码
<%@page session="false" %>
<%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ page pageEncoding="UTF-8" contentType="text/html; charset=UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path;
%>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>用户失效</title>
</head>
<body>
你的登录已经失效，请重新登录。
<br />
<a href="<c:url value='/login.jsp'/>" >
点击这里登录</a>
</body>
</html>
7、在com.xxx.security包下创建登录验证过滤器，该过滤器可用于在管理员登录时进行日志记录等相关操作，包括两个类：
LoginUsernamePasswordAuthenticationFilter
LoginSuccessHandler
7.1）LoginUsernamePasswordAuthenticationFilter代码如下：
Java代码
package com.xxx.security;
import org.springframework.security.web.authentication.UsernamePasswordAuthenticationFilter;
public class LoginUsernamePasswordAuthenticationFilter extends
UsernamePasswordAuthenticationFilter {
}
7.2）LoginSuccessHandler代码如下：
Java代码
package com.xxx.security;
import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.security.core.Authentication;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.web.authentication.SavedRequestAwareAuthenticationSuccessHandler;
/**
* 处理管理员登录日志
*
*/
public class LoginSuccessHandler extends SavedRequestAwareAuthenticationSuccessHandler{
@Override
public void onAuthenticationSuccess(HttpServletRequest request,
HttpServletResponse response, Authentication authentication) throws IOException,
ServletException {
UserDetails userDetails = (UserDetails)authentication.getPrincipal();
//输出登录提示信息
System.out.println("管理员 " + userDetails.getUsername() + " 登录");
super.onAuthenticationSuccess(request, response, authentication);
}
}
8、在applicationContext-security.xml中加入权限管理配置，如下：
Xml代码
<?xml version="1.0" encoding="UTF-8"?>
<beans:beans xmlns="http://www.springframework.org/schema/security"
xmlns:b="http://www.springframework.org/schema/beans" xmlns:beans="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/security http://www.springframework.org/schema/security/spring-security-3.1.xsd">
<http >
<!-- 不拦截login.jsp -->
<intercept-url pattern="/login.jsp*" access="IS_AUTHENTICATED_ANONYMOUSLY" />
<!--仅拦截到manager下面的内容，具备access对应权限的-->
<intercept-url pattern="/manager/**" access="ROLE_ADMIN,ROLE_UPDATE_FILM,ROLE_DELETE_FILM,ROLE_ADD_FILM" />
<!-- 设置登录过滤器 -->
<custom-filter before="FORM_LOGIN_FILTER" ref="authenticationProcessingFilter" />
<!-- 登录表单设置 -->
<form-login login-page="/login.jsp"
default-target-url="/manager/films.jsp"
authentication-failure-url="/login.jsp?error=true" />
<!-- 登出操作后跳转到该页面 -->
<logout logout-success-url="/loggedout.jsp"
delete-cookies="JSESSIONID" />
<remember-me />
<!-- SESSION超时后跳转到该页面 -->
<session-management invalid-session-url="/timeout.jsp">
</session-management>
</http>
<authentication-manager alias="authenticationManager">
<authentication-provider>
<!--
直接使用SQL语句查询登录帐号对应权限，
users-by-username-query：查询登录用户是否存在
authorities-by-username-query：查询登录用户权限(登录用户可以不属于任何组，从t_user_role表中获取权限)
group-authorities-by-username-query：查询登录用户所在组的权限
-->
<jdbc-user-service data-source-ref="dataSource"
group-authorities-by-username-query="SELECT g.id,g.groupname,role.role
FROM t_group AS g
LEFT OUTER JOIN t_group_role AS grouprole ON (g.id = grouprole.groupid)
LEFT OUTER JOIN t_role AS role ON (role.id = grouprole.roleid)
LEFT OUTER JOIN t_group_user AS groupuser on (g.id = groupuser.groupid)
LEFT OUTER JOIN t_admin ON (t_admin.id = groupuser.userid)
WHERE t_admin.nickname = ?"
users-by-username-query="SELECT t_admin.nickname AS username,t_admin.passwd as password,'true' AS enabled
FROM t_admin
WHERE t_admin.nickname = ?"
authorities-by-username-query="SELECT t_admin.nickname AS username,role.role as authorities
FROM t_admin
LEFT OUTER JOIN t_user_role AS userrole ON(t_admin.id = userrole.userid)
LEFT OUTER JOIN t_role AS role ON (userrole.roleid = role.id)
WHERE t_admin.nickname = ?" />
</authentication-provider>
</authentication-manager>
<!-- 自定义消息 -->
<b:bean id="messageSource"
class="org.springframework.context.support.ReloadableResourceBundleMessageSource">
<b:property name="basename"
value="classpath:org/springframework/security/messages" />
</b:bean>
<!-- 定制登录过滤器 -->
<beans:bean id="loginSuccessHandler" class="com.xxx.security.LoginSuccessHandler">
<b:property name="defaultTargetUrl">
<!-- 登录成功后转发到该页面 -->
<b:value>/manager/films.jsp</b:value>
</b:property>
</beans:bean>
<beans:bean id="authenticationProcessingFilter" class="com.xxx.security.LoginUsernamePasswordAuthenticationFilter">
<beans:property name="authenticationSuccessHandler" ref="loginSuccessHandler"></beans:property>
<beans:property name="authenticationFailureHandler" ref="authenticationFailureHandler"></beans:property>
<beans:property name="authenticationManager" ref="authenticationManager"></beans:property>
</beans:bean>
<beans:bean id="authenticationFailureHandler" class="org.springframework.security.web.authentication.SimpleUrlAuthenticationFailureHandler">
<beans:property name="defaultFailureUrl">
<!-- 登录失败后转发到该页面 -->
<beans:value>/login.jsp?error=true</beans:value>
</beans:property>
</beans:bean>
</beans:beans>
9、为影片页面films.jsp定制操作权限，定制后，不同的帐号登录会看到不同的操作，
比如，帐号"admin"属于权限组"Administrator"，具备权限"ROLE_ADMIN"，登录后
可以看到所有操作，帐号"test"属于权限组"影片维护"，具备权限"ROLE_UPDATE_FILM"
和"ROLE_ADD_FILM"，登录后只能看到"添加影片信息"和"修改"操作
films.jsp页面权限分布图：
films.jsp代码如下：
Html代码
<%@ page language="java" contentType="text/html; charset=utf-8"
pageEncoding="utf-8" %>
<%@taglib uri="/struts-tags" prefix="s" %>
<%@ taglib prefix="security"
uri="http://www.springframework.org/security/tags"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>信息操作</title>
</head>
<body>
<s:form action="/film/findFilm" method="post">
<s:submit value=" 获取所有影片信息 "></s:submit>
</s:form>
<!-- 添加影片操作，登录帐号具备ROLE_ADMIN权限或者ROLE_ADD_FILM权限可以执行 -->
<security:authorize ifAnyGranted="ROLE_ADMIN,ROLE_ADD_FILM">
<a href="<%=basePath %>manager/insertFilm.jsp">添加影片信息</a><br />
</security:authorize>
<s:if test="filmList != null">
<table border="1" width="40%">
<tr>
<th>序号</th><th>影片名</th><th>操作</th>
</tr>
<%-- 遍历影片信息 --%>
<s:iterator var="film" value="filmList" status="st">
<tr>
<td><s:property value="#st.index+1" /></td>
<td><s:property value="fname" /></td>
<td>
<!-- 修改影片操作，登录帐号具备ROLE_ADMIN权限或者ROLE_UPDATE_FILM权限可以执行 -->
<security:authorize ifAnyGranted="ROLE_ADMIN,ROLE_UPDATE_FILM">
<s:url id="detailUrl" value="/film/detailFilm">
<s:param name="id" value="%{id}"/>
</s:url>
<s:a href="%{detailUrl}">[修改]</s:a>
</security:authorize>
<!-- 删除影片操作，登录帐号具备ROLE_ADMIN权限或者ROLE_DELETE_FILM权限可以执行 -->
<security:authorize ifAnyGranted="ROLE_ADMIN,ROLE_DELETE_FILM">
<s:url id="deleteUrl" value="/film/deleteFilm">
<s:param name="id" value="%{id}"/>
</s:url>
<s:a href="%{deleteUrl}">[删除]</s:a>
</security:authorize>
</td>
</tr>
</s:iterator>
</table>
</s:if>
</body>
