一、在web.xml中添加shiro过滤器

    <!-- Shiro filter-->  
    <filter>  
        <filter-name>shiroFilter</filter-name>  
        <filter-class>  
            org.springframework.web.filter.DelegatingFilterProxy  
        </filter-class>  
    </filter>  
    <filter-mapping>  
        <filter-name>shiroFilter</filter-name>  
        <url-pattern>/*</url-pattern>  
    </filter-mapping>  

二、在Spring的applicationContext.xml中添加shiro配置

1、添加shiroFilter定义

<!-- Shiro Filter -->  
<bean id="shiroFilter" class="org.apache.shiro.spring.web.ShiroFilterFactoryBean">  
    <property name="securityManager" ref="securityManager" />  
    <property name="loginUrl" value="/login" />  
    <property name="successUrl" value="/user/list" />  
    <property name="unauthorizedUrl" value="/login" />  
    <property name="filterChainDefinitions">  
        <value>  
            /login = anon  
            /user/** = authc  
            /role/edit/* = perms[role:edit]  
            /role/save = perms[role:edit]  
            /role/list = perms[role:view]  
            /** = authc  
        </value>  
    </property>  
</bean> 

2、添加securityManager定义

<bean id="securityManager" class="org.apache.shiro.web.mgt.DefaultWebSecurityManager">  
    <property name="realm" ref="myRealm" />  
</bean>

3、添加realm定义

    <bean id=" myRealm" class="com...MyRealm" />  

三、实现MyRealm：继承AuthorizingRealm，并重写认证授权方法

    public class MyRealm extends AuthorizingRealm{  
      
        private AccountManager accountManager;  
        public void setAccountManager(AccountManager accountManager) {  
            this.accountManager = accountManager;  
        }  
      
        /** 
         * 授权信息 
         */  
        protected AuthorizationInfo doGetAuthorizationInfo(  
                    PrincipalCollection principals) {  
            String username=(String)principals.fromRealm(getName()).iterator().next();  
            if( username != null ){  
                User user = accountManager.get( username );  
                if( user != null && user.getRoles() != null ){  
                    SimpleAuthorizationInfo info = new SimpleAuthorizationInfo();  
                    for( SecurityRole each: user.getRoles() ){  
                            info.addRole(each.getName());  
                            info.addStringPermissions(each.getPermissionsAsString());  
                    }  
                    return info;  
                }  
            }  
            return null;  
        }  
      
        /** 
         * 认证信息 
         */  
        protected AuthenticationInfo doGetAuthenticationInfo(  
                    AuthenticationToken authcToken ) throws AuthenticationException {  
            UsernamePasswordToken token = (UsernamePasswordToken) authcToken;  
            String userName = token.getUsername();  
            if( userName != null && !"".equals(userName) ){  
                User user = accountManager.login(token.getUsername(),  
                                String.valueOf(token.getPassword()));  
      
                if( user != null )  
                    return new SimpleAuthenticationInfo(  
                                user.getLoginName(),user.getPassword(), getName());  
            }  
            return null;  
        }  
      
    }
