每天学点Shiro-从数据库中读取资源权限

1. 新建能够从数据库中读取资源权限并构建FilterChainDefinitionMap的工程类

   

public class FilterChainDefinitionMapFactory {

    public LinkedHashMap<String,String> build(){
        LinkedHashMap<String,String> map = new LinkedHashMap<>() ;
        /*
         <property name="filterChainDefinitions">
            &lt;!&ndash;anon表示可不需要登录态&ndash;&gt;
            &lt;!&ndash;authc表示需要登录态&ndash;&gt;
            &lt;!&ndash;前面的优先被匹配&ndash;&gt;
            <value>
                /test/hello.do = anon
                /user/login.do = anon

                /page/admin.do = roles[admin]
                /page/*.do = roles[user]

                /** = authc
            </value>
        </property>
         */
        map.put("/test/hello.do","anon") ;
        map.put("/user/login.do","anon") ;
        map.put("/page/admin.do","roles[admin]") ;
        map.put("/page/*.do","roles[user]") ;
        map.put("/**","authc") ;
        return map ;
    }

}

2. 在spring-context-shiro.xml文件中进行如下配置
