AccessControlFilter
- 访问控制过滤器,继承PathMatchingFilter过滤器,重写onPreHandle办法.
- isAccessAllowed 是否容许拜访
onAccessDenied 是否回绝拜访
咱们通过重写上边两个办法来管制过滤逻辑,实现以后的需要,用户不登录点赞提醒请登录
- 定义一个LoginAuthFilter继承AccessControlFilter
前端js渲染脚本
// 前端弹窗的js代码private static final String JS = "<script type='text/javascript'>var wp=window.parent; if(wp!=null){while(wp.parent&&wp.parent!==wp){wp=wp.parent;}wp.location.href='%1$s';}else{window.location.href='%1$s';}</script>";private String loginUrl = "/login";重写isAccessAllowed办法判断用户是否登录
@Overrideprotected boolean isAccessAllowed( ServletRequest request, ServletResponse response, Object mappedValue) throws Exception { Subject subject = SecurityUtils.getSubject(); if (null != subject) { if (subject.isRemembered()) { return true; } if (subject.isAuthenticated()) { return true; } } return false;}重写onAccessDenied办法,ajax申请返回谬误code,提醒‘请登录’否则跳转到登录页
