DefaultFilterChainManager会默认添加org.apache.shiro.web.filter.mgt.DefaultFilter中声明的拦截器：
- public enum DefaultFilter {
- anon(AnonymousFilter.class),
- authc(FormAuthenticationFilter.class),
- authcBasic(BasicHttpAuthenticationFilter.class),
- logout(LogoutFilter.class),
- noSessionCreation(NoSessionCreationFilter.class),
- perms(PermissionsAuthorizationFilter.class),
- port(PortFilter.class),
- rest(HttpMethodPermissionFilter.class),
- roles(RolesAuthorizationFilter.class),
- ssl(SslFilter.class),
- user(UserFilter.class);
- }
【shiro】authc与logout
