spring+shiro 整合实例代码详解

一、添加相关依赖

<dependency>
<groupId>org.apache.shiro</groupId>
<artifactId>shiro-core</artifactId>
<version>1.2.1</version>
</dependency>
<dependency>
<groupId>org.apache.shiro</groupId>
<artifactId>shiro-web</artifactId>
<version>1.2.1</version>
</dependency>
<dependency>
<groupId>org.apache.shiro</groupId>
<artifactId>shiro-ehcache</artifactId>
<version>1.2.1</version>
</dependency>
<dependency>
<groupId>org.apache.shiro</groupId>
<artifactId>shiro-spring</artifactId>
<version>1.2.1</version>
</dependency>
<dependency>
<groupId>commons-logging</groupId>
<artifactId>commons-logging</artifactId>
<version>1.2</version>
</dependency>

二、编写代码

1、自定义realm

public class CommonRealm extends AuthorizingRealm {
@Autowired
private UserLoginService userLoginService;
@Override
public String getName() {
return "CommonRealm";
}
//授权
@Override
protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {
String usernmae = (String) principals.getPrimaryPrincipal();
List<String> permissions = new ArrayList<String>();
if ("admin".equals(usernmae)) {
permissions.add("admin:ee");
}
SimpleAuthorizationInfo info = new SimpleAuthorizationInfo();
info.addStringPermissions(permissions);
return info;
}
//身份认证
@Override
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
String username = (String) token.getPrincipal();
User user = userLoginService.getUser(username);
if (user == null) {
return null;
}
SimpleAuthenticationInfo info = new SimpleAuthenticationInfo(username, user.getPassword(), getName());
return info;
}
}

2、login controller

@Controller
public class UserAction {
@Autowired
private UserLoginService userLoginService;
@RequestMapping("/login.do")
public String userLogin(HttpServletRequest request, String username, String password) throws Exception {
// 如果登陆失败从request中获取异常信息，shiroLoginFailure就是shiro异常类的全限定名
String exceptionClassName = (String) request.getAttribute("shiroLoginFailure");
if (exceptionClassName != null) {
if (UnknownAccountException.class.getName().equals(exceptionClassName)) {
// 最终会抛给异常处理器
throw new XXXException("用户名不存在");
} else if (IncorrectCredentialsException.class.getName().equals(exceptionClassName)) {
throw new XXXException("用户名/密码错误");
} else {
throw new Exception();// 最终在异常处理器生成未知错误
}
}
// 如果登录成功的话不走此方法，shiro认证成功会自动跳转到上一个请求路径，配的的successUrl没效果，后边会说
// 登陆失败走此方法，捕获异常，然后 return ~ ,还到login页面
return "login.jsp";
}
}

3、检测权限 controller

//此方法为了验证权限是否生效
@RequestMapping("/findAll.do")
@RequiresPermissions("admin:ee")
public ModelAndView list(HttpServletRequest request){
.......
}

三、常见问题

因为有一些特别常见的问题，需要修改xml配置，所以现在先手问题，把xml配置放在后边，直接就配置完善好的xml

问题一：登陆成功后shiro默认跳到上一次请求，没有上一次请求默认跳到/  ，那我们就想控制调到自己定义的路径咋办呢？

解决方案：

步骤一：继承FormAuthenticationFilter类，重写onLoginSuccess方法，这里可以自定义路径，因为这里自定义了成功跳转的路径，所以配置里的successUrl不用配置，赔了也没效果。。

public class LoginSuccessToFilter extends FormAuthenticationFilter {
@Override
protected boolean onLoginSuccess(AuthenticationToken token, Subject subject, ServletRequest request, ServletResponse response) throws Exception {
WebUtils.getAndClearSavedRequest(request);
WebUtils.redirectToSavedRequest(request,response,"/findAll.do");
return false;
}
}

步骤二：

在shiro的xml配置文件中配置

<bean id="myfilter" class="com.xxx.realm.LoginSuccessToFilter"></bean>

在 shiroFilter配置中引入,完整xml在后边

<bean id="shiroFilter" class="org.apache.shiro.spring.web.ShiroFilterFactoryBean">
<property name="filters">
<map>
<entry key="authc" value-ref="myfilter"></entry>
</map>
</property>
</bean>
<bean id="shiroFilter" class="org.apache.shiro.spring.web.ShiroFilterFactoryBean">
<property name="filters">
<map>
<entry key="authc" value-ref="myfilter"></entry>
</map>
</property>
</bean>

四、Xml配置

applicationContext-shiro.xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"

</map>
</property>
<!-- 拦截到，跳转到的地址,通过此地址去认证 -->
<property name="loginUrl" value="/login.do"/>

</beans>

springmvc的配置

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:aop="http://www.springframework.org/schema/aop"

<context:component-scan base-package="com.dhl.controller"></context:component-scan>
<mvc:annotation-driven></mvc:annotation-driven>
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"></bean>
<!-- 开启shiro注解的配置移动到这儿 -->
<bean class="org.springframework.aop.framework.autoproxy.DefaultAdvisorAutoProxyCreator" depends-on="lifecycleBeanPostProcessor">
<property name="proxyTargetClass" value="true" />
</bean>
<bean class="org.apache.shiro.spring.security.interceptor.AuthorizationAttributeSourceAdvisor">

</bean>
</beans>
