shiro post表单提交认证

post表单提交认证成功后会调用 boolean onLoginSuccess(AuthenticationToken token, Subject subject, ServletRequest request, ServletResponse response) 方法（源码可以看到（通过boolean onAccessDenied(ServletRequest request, ServletResponse response)源码点进去）），而自己通过subject 认证的要自己去调用boolean onLoginSuccess(AuthenticationToken token, Subject subject, ServletRequest request, ServletResponse response) 方法
