403状态和LaztInitializationException Spring Security + JWT

如何解决403状态和LaztInitializationException Spring Security + JWT

我尝试使用JWT令牌和Spring Security来获取所有用户。我的源代码如下：

Spring Console

提前谢谢！ ：）

解决方法

我终于解决了问题。它将@Transactional批注引用到loadUserByUsername方法上，该方法是UserDetailsS​​ervice的替代方法，在UserService上实现。 @ChristopherSchneider再次感谢您的帮助！ ：）

   @Transactional
        @Override
        public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
            User user = userRepository.findByUserName(username);
            if (user == null) {
                throw new UsernameNotFoundException("User not found with username: " + username);
            }
            return new org.springframework.security.core.userdetails.User(user.getUsername(),user.getPassword(),user.getAuthorities());
        }
