【shiro]登陆的时候，getCurrentPrincipal有值，再次调用就空了


```
登录的时候

Subject subject = SecurityUtils.getSubject();
subject.login(new AuthAccountToken(account));

此时是有值的

再次调用

AuthPrincipal user = this.getCurrentPrincipal();

```
user就是空值了，请问该怎么去查

this.getCurrentPrincipal();

是啥东西，没用过

就这玩意儿

 Subject subject = SecurityUtils.getSubject();
 Session session = subject.getSession();
 PrincipalCollection principals = (PrincipalCollection)session.getAttribute(DefaultSubjectContext.PRINCIPALS_SESSION_KEY);
 if (null == principals) return null;
 AuthPrincipal principal = (AuthPrincipal)principals.getPrimaryPrincipal();
 return principal;
