今天在配置SpringSecurity记住我功能的时候项目启动出现了这样一个异常：

Invalid remember-me token (Series/token) mismatch. Implies previous cookie theft attack._获取用户信息

Invalid remember-me token (Series/token) mismatch. Implies previous cookie theft attack._获取用户信息_02

Invalid remember-me token (Series/token) mismatch. Implies previous cookie theft attack._获取用户信息_03

原来是我在配置记住我的时候忘记了添加UserDetailsService实现类，UserDetailsService的作用就是获取用户信息进行校验，记住我功能需要使用浏览器Cookie中的Token进行用户校验：

Invalid remember-me token (Series/token) mismatch. Implies previous cookie theft attack._获取用户信息_04

最后加上UserDetailsService实现类即可：

Invalid remember-me token (Series/token) mismatch. Implies previous cookie theft attack._获取用户信息_05
