shiro中anon配置不生效

再配置shiro的時候，如下代碼要注意：

1、下述代碼中必須是LinkedHashMap 而不能是HashMap。

2、anon定義必須在authc之前

否則anon定義不生效

  @Bean
        public ShiroFilterFactoryBean shiroFilterFactoryBean(SecurityManager securityManager){
            ShiroFilterFactoryBean factoryBean = new ShiroFilterFactoryBean();
            factoryBean.setSecurityManager(securityManager);

//            設置登錄跳轉
            factoryBean.setLoginUrl("/admin");
            factoryBean.setSuccessUrl("/admin/index");

            //必須為LinkedHashMap 否則anon不生效
            Map<String,String> map = new LinkedHashMap<>();

            //退出
            map.put("/admin/logout","logout");

            //登錄頁面和登錄驗證不要攔截
            map.put("/admin/login.html","anon");
            map.put("/admin/tologin","anon");

            //設置需要過濾的鏈接
            map.put("/admin/**","authc");



            factoryBean.setFilterChainDefinitionMap(map);

            return factoryBean;
        }
