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;         }
