shiro中anon配置不生效

再配置shiro的时候，如下代码要注意：

1、下述代码中必须是LinkedHashMap 而不能是HashMap。

2、anon定义必须在authc之前

否则anon定义不生效

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

//            设置登录跳转
            factoryBean.setLoginUrl("/admin");
            factoryBean.setSuccessUrl("/admin/index");

            //必须为LinkedHashMap 否则anon不生效
            Map<String,String> map = new LinkedHashMap<>();

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

            //登录页面和登录验证不要拦截
            map.put("/admin/login.html","anon");
            map.put("/admin/tologin","anon");

            //设置需要过滤的链接
            map.put("/admin/**","authc");

            factoryBean.setFilterChainDefinitionMap(map);

            return factoryBean;
        }
