Shiro+Spring整合(超详细，有demo)

2017-11-02 16:22 162 查看

刚刚看了Shiro的入门视频，学习了了Shiro的一些知识，感谢Java_小锋老师的学习视频，在这里我分享一下我的学习心得，同时算对自己这俩天学习的总结，同时将Shiro整合到Spring中。

好了，我简单说一下大概需要学习的东西吧。Shiro的官网上的知识点很多。作为入门，可以先记住Shiro核心的点

1、权限认证

2、授权

3、permissions权限

4、Realm

现在开始配置：

第一步：配置Web.xml, shiro核心的配置就是第一个。所有的过滤都会经过org.springframework.web.filter.DelegatingFilterProxy

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">
<display-name>MyWeb</display-name>
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>

<!-- shiro过滤器定义 ，一定要放在最前面-->
<filter>
<filter-name>shiroFilter</filter-name>
<filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
<init-param>
<!-- 该值缺省为false,表示生命周期由SpringApplicationContext管理,设置为true则表示由ServletContainer管理 -->
<param-name>targetFilterLifecycle</param-name>
<param-value>true</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>shiroFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>

<!-- Spring配置文件 -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml</param-value>
</context-param>
<!-- 编码过滤器 -->
<filter>
<filter-name>encodingFilter</filter-name>
<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
<async-supported>true</async-supported>
<init-param>
<param-name>encoding</param-name>
<param-value>UTF-8</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>encodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<!-- Spring监听器 -->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

<!-- 添加对springmvc的支持 -->
<servlet>
<servlet-name>springMVC</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring-mvc.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
<async-supported>true</async-supported>
</servlet>
<servlet-mapping>
<servlet-name>springMVC</servlet-name>
<url-pattern>*.do</url-pattern>
</servlet-mapping>

</web-app>

第二步：配置applicationContext.xml，都有注释，其中Shiro连接约束配置就体现了，Shiro中的权限认证

和permissions权限的问题，请注意shiro过滤器里面的内容，后面我们会按照身份验证，角色验证和权限验证去演示。我已经提前在shiro过滤器里面配置好了。

</property>
</bean>

<bean class="org.apache.shiro.spring.security.interceptor.AuthorizationAttributeSourceAdvisor">
<property name="securityManager" ref="securityManager"/>

<!-- 配置事务通知属性 -->

<aop:pointcut id="serviceOperation"
expression="execution(* com.web.*.service.*.*(..))" />
<aop:advisor advice-ref="txAdvice" pointcut-ref="serviceOperation" />
</aop:config>

</beans>

第三步：我们需要自定义的MyRealm，代码如下：

package com.web.demo.util;

import javax.annotation.Resource;

import org.apache.shiro.authc.AuthenticationException;
import org.apache.shiro.authc.AuthenticationInfo;
import org.apache.shiro.authc.AuthenticationToken;
import org.apache.shiro.authc.SimpleAuthenticationInfo;
import org.apache.shiro.authz.AuthorizationInfo;
import org.apache.shiro.authz.SimpleAuthorizationInfo;
import org.apache.shiro.realm.AuthorizingRealm;
import org.apache.shiro.subject.PrincipalCollection;
import org.springframework.beans.factory.annotation.Autowired;

import com.web.demo.model.User;
import com.web.demo.service.UserService;

public class MyRealm extends AuthorizingRealm{

@Autowired
private UserService userService;

/**
* 为当前登录的账号授予角色和权限
* 描述：此方法是继承AuthorizingRealm，所有的信息都是封装
*/
@Override
protected AuthorizationInfo doGetAuthorizationInfo(
PrincipalCollection principals) {
String userName = (String) principals.getPrimaryPrincipal();
SimpleAuthorizationInfo authorizationInfo = new SimpleAuthorizationInfo();
// 封装角色信息
authorizationInfo.setRoles(userService.getRoles(userName));
// 封装权限信息
authorizationInfo.setStringPermissions(userService
.getPermissions(userName));
return authorizationInfo;
}

/**
* 验证当前登录的用户
*/
@Override
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
String userName=(String)token.getPrincipal();
User user=userService.getByUserName(userName);
if(user!=null){
//参数说明，参数1：数据库获取用户名 ，参数2：数据库获取的密码，参数3：RealmName，这个随便起，无所谓。将这些参数传入，与用户输入的进行对比
AuthenticationInfo authcInfo=new SimpleAuthenticationInfo(user.getUserName(),user.getPassword(),"xx");
return authcInfo;
}else{
return null;
}
}

}

第四步：controller层的测试代码

package com.web.demo.controller;

import javax.servlet.http.HttpServletRequest;

import org.apache.shiro.SecurityUtils;
import org.apache.shiro.authc.UsernamePasswordToken;
import org.apache.shiro.session.Session;
import org.apache.shiro.subject.Subject;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

import com.web.demo.model.User;

/**
* 用户Controller层
* @author Administrator
*
*/
@Controller
@RequestMapping("/user")
public class UserController {

/**
* 用户登录
* @param user
* @param request
* @return
*/
@RequestMapping("/login")
public String login(User user,HttpServletRequest request){
Subject subject=SecurityUtils.getSubject();
UsernamePasswordToken token=new UsernamePasswordToken(user.getUserName(), user.getPassword());
try{
subject.login(token);
Session session=subject.getSession();
System.out.println("sessionId:"+session.getId());
System.out.println("sessionHost:"+session.getHost());
System.out.println("sessionTimeout:"+session.getTimeout());
session.setAttribute("info", "session的数据");
return "redirect:/success.jsp";
}catch(Exception e){
e.printStackTrace();
request.setAttribute("user", user);
request.setAttribute("errorMsg", "用户名或密码错误！");
return "index";
}
}

@RequestMapping("/student")
public String student(User user,HttpServletRequest request){
return "redirect:/demo/jsp/student.jsp";
}

}

第五步：success.jsp和student.jsp页面，

<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<%@ taglib prefix="shiro" uri="http://shiro.apache.org/tags" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Insert title here</title>
</head>
<body>
${info }
欢迎你!
<shiro:hasRole name="admin">
欢迎有admin角色的用户！<shiro:principal/>
</shiro:hasRole>
<shiro:hasPermission name="student:create">
欢迎有student:create权限的用户！<shiro:principal/>
</shiro:hasPermission>
</body>
</html>

上面是success.jsp代码。注意shiro也有jsp标签，比如就是判断当前页面用户是否是admin角色，比如判断当前用户是否拥有教师角色下的创建权限

student.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<%@ taglib prefix="shiro" uri="http://shiro.apache.org/tags" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title></title>
</head>
<body>

您好，老师!我是role为teacher才能进入的页面
<%-- <shiro:hasRole name="admin">
欢迎有admin角色的用户！<shiro:principal/>
</shiro:hasRole>
<shiro:hasPermission name="student:create">
欢迎有student:create权限的用户！<shiro:principal/>
</shiro:hasPermission> --%>
</body>
</html>

好了，核心代码基本是贴完了，我这边演示一下，主要从身份验证，角色验证，权限验证三个方面去演示。

1、身份验证，测试。

我们先不登陆，直接访问controller，试试，会发现强制进入登陆页面，这就是身份验证
