问题随记
在使用 AuthenticationManager 的时候,出现循环依赖问题 ------ java.lang.StackOverflowError
,查资料查了两天半,终于找到原因。

问题解决
在查找很多资料以及再次复现代码后,终于找到问题,问题出在自己实现的 MyUserDetailsServiceImpl 没有继承 UserDetailsService,才导致该问题。
让 MyUserDetailsServiceImpl 使用 UserDetailsService 该接口或者让 MyUserDetailsServiceImpl 使用的 MyUserDetailsService 继承 UserDetailsService 接口即可
java
// 方法 1
@Service
public class MyUserDetailsServiceImpl implements MyUserDetailsService, UserDetailsService {
@Autowired
private UserService userService;
@Override
public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
UserEntity user = userService.findByUsername(username);
if (user == null) {
throw new UsernameNotFoundException("User not found");
}
return new SecurityUser(user);
}
}
// 方法 2
public interface MyUserDetailsService extends UserDetailsService {
UserDetails loadUserByUsername(String username) throws UsernameNotFoundException;
}
出现该问题的原因可能不止这一个,比如使用两种登录机制出现该问题就要使用 @Lazy
来解决该问题
