Shiro引入Spring
添加jar包/maven配置
<!-- shiro支持 -->
<dependency>
<groupId>org.apache.shiro</groupId>
<artifactId>shiro-core</artifactId>
<version>1.2.4</version>
</dependency>
<dependency>
<groupId>org.apache.shiro</groupId>
<artifactId>shiro-web</artifactId>
<version>1.2.4</version>
</dependency>
<dependency>
<groupId>org.apache.shiro</groupId>
<artifactId>shiro-spring</artifactId>
<version>1.2.4</version>
</dependency>
<!-- 缓存 注解 -->
<dependency>
<groupId>org.apache.shiro</groupId>
<artifactId>shiro-aspectj</artifactId>
<version>1.2.4</version>
</dependency>
<dependency>
<groupId>org.apache.shiro</groupId>
<artifactId>shiro-ehcache</artifactId>
<version>1.2.4</version>
</dependency>
添加spring-shiro.xml配置文件
<?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"

<!-- 自定义Realm -->
<bean id="myRealm" class="shiro03.realm.MyRealm"/>

<bean id="securityManager" class="org.apache.shiro.web.mgt.DefaultWebSecurityManager">
<property name="realm" ref="myRealm"/>
</bean>
<!-- 配置任何角色 -->
<bean id="anyofroles" class="shiro03.realm.AnyOfRolesAuthorizationFilter"/>
<!-- Shiro过滤器 -->
<bean id="shiroFilter" class="org.apache.shiro.spring.web.ShiroFilterFactoryBean">
<!-- Shiro的核心安全接口,这个属性是必须的 -->
<property name="securityManager" ref="securityManager"/>
<!-- 身份认证失败，则跳转到登录页面的配置 -->
<property name="loginUrl" value="/index.jsp"/>
<!-- 权限认证失败，则跳转到指定页面 -->
<property name="unauthorizedUrl" value="/unauthorized.jsp"/>
<!-- <property name="anyofroles" ref="anyofroles"/> -->
<!-- Shiro连接约束配置,即过滤链的定义 -->
<property name="filterChainDefinitions">
<value>
/login=anon
/admin*=authc
/student=anyofroles["admin,teacher"]
/teacher=roles[admin]
</value>
</property>
</bean>
<!-- 保证实现了Shiro内部lifecycle函数的bean执行 -->
<bean id="lifecycleBeanPostProcessor" class="org.apache.shiro.spring.LifecycleBeanPostProcessor"/>
<!-- 开启Shiro注解 -->
<bean class="org.springframework.aop.framework.autoproxy.DefaultAdvisorAutoProxyCreator" depends-on="lifecycleBeanPostProcessor"/>
<bean class="org.apache.shiro.spring.security.interceptor.AuthorizationAttributeSourceAdvisor">
<property name="securityManager" ref="securityManager"/>
</bean>
</beans>
自定义Realm类MyRealm.java
public class MyRealm extends AuthorizingRealm{
@Resource
private UserService userService;
/**
* 为当限前登录的用户授予角色和权
*/
@Override
protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {
String userName=(String)principals.getPrimaryPrincipal();
SimpleAuthorizationInfo authorizationInfo=new SimpleAuthorizationInfo();
authorizationInfo.setRoles(userService.getRoles(userName));
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){
AuthenticationInfo authcInfo=new SimpleAuthenticationInfo(user.getUserName(),user.getPassword(),"xx");
return authcInfo;
}else{
return null;
}
}
}
自定义角色过滤器AnyOfRolesAuthorizationFilter.java
当一个角色有多个功能模块页面的权限时，会出现权限失效问题，无法配置，需要自己定义角色过滤器。
public class AnyOfRolesAuthorizationFilter extends RolesAuthorizationFilter{
@Override
public boolean isAccessAllowed(ServletRequest request, ServletResponse response, Object mappedValue)
throws IOException {
Subject subject = getSubject(request, response);
String[] rolesArray = (String[]) mappedValue;
if (rolesArray == null || rolesArray.length == 0) {
return true;
}
for (String roleName : rolesArray) {
if (subject.hasRole(roleName)) {
return true;
}
}
return false;
}
}
