Springboot集成shiro记住我功能出错.

Question

2019-01-17 14:36:57,384 - Authentication failed for token submission [org.apache.shiro.authc.UsernamePasswordToken - null, rememberMe=false (0:0:0:0:0:0:0:1)].  Possible unexpected error? (Typical or expected login exceptions should extend from AuthenticationException).
java.lang.NullPointerException: null

只要是记住我字段进来就出错.否则没事.
这样是没错的:

UsernamePasswordToken token = new UsernamePasswordToken(name,password);

这样就报错了:

UsernamePasswordToken token = new UsernamePasswordToken(name, password, subject.isRemembered());

或者这样也报错:

 UsernamePasswordToken token = new UsernamePasswordToken(name, password, rememberMe);
