我正在写一个RESTMVC应用程序。我用的是SpringBoot和hibernate。为了保护，我决定将Spring Security 和jwt添加到项目中。
我用 BCryptEncoder 对密码进行编码。因此，我把它放在 JWTTokenProvider 像豆子一样上课。我需要注射 PasswordEncoder 进入 UserService 同学们，但我不能。我明白原因，但我不知道怎么解决。 UserSevice :

@RequiredArgsConstructor
@Service
public class UserService {

    private final UserRepository userRepository;

    private final UserMapper userMapper;

    private final PasswordEncoder passwordEncoder;

    public UserDTO registration (RegistrationUserDTO registrationUserDTO){

        User user = new User();

        user.setName(registrationUserDTO.getName());
        user.setLastName(registrationUserDTO.getLastName());
        user.setLogin(registrationUserDTO.getLogin());
        user.setMail(registrationUserDTO.getMail());
        user.setPassword(passwordEncoder.encode(registrationUserDTO.getPassword()));
        user.setRole(Role.CUSTOMER);

        userRepository.save(user);

        return userMapper.userToUserDTO(user);
    }
}
``` `JwtTokenProvider` :

@RequiredArgsConstructor
@Component
public class JwtTokenProvider {

// Fields
//
private final UserDetailsService userDetailsService;

@Value("${jwt.token.secret}")
private String secret;

@Value("${jwt.token.expired}")
private Long validityInMilliSeconds;

// METHODS
//

@Bean
public BCryptPasswordEncoder passwordEncoder() {
    return new BCryptPasswordEncoder(8);
}

@PostConstruct
protected void init() {
    secret = Base64.getEncoder().encodeToString(secret.getBytes());
}

/**
 *
 * @param login
 * @param role
 * @return ТОКЕН
 */
public String createToken(String login, Role role) {

    Claims claims = Jwts.claims().setSubject(login);
    claims.put("roles", role.name());

    Date now = new Date();
    Date validity = new Date(now.getTime() + validityInMilliSeconds);

    return Jwts.builder()
            .setClaims(claims)
            .setIssuedAt(now)
            .setExpiration(validity)
            .signWith(SignatureAlgorithm.HS256, secret)
            .compact();
}

public Authentication getAuthentication(String token) {
    UserDetails userDetails = this.userDetailsService.loadUserByUsername(getLogin(token));
    return new UsernamePasswordAuthenticationToken(userDetails, "", userDetails.getAuthorities());
}

public String getLogin(String token) {
    return Jwts.parser().setSigningKey(secret).parseClaimsJws(token).getBody().getSubject();
}

public boolean validateToken(String token) {
    try {
        Jws<Claims> claims = Jwts.parser().setSigningKey(secret).parseClaimsJws(token);

        return !claims.getBody().getExpiration().before(new Date());

    } catch (JwtException | IllegalArgumentException e) {
        throw new JwtAuthenticationException("JWT token is expired or invalid");
    }
}

/**
 *
 * @param req
 * @return bearerToken
 */
public String resolveToken(HttpServletRequest req) {
    String bearerToken = req.getHeader("Authorization");
    if (bearerToken != null && bearerToken.startsWith("Bearer ")) {
        return bearerToken.substring(7);
    }
    return null;
}

}
``` JwtUserDetailsService :

@Slf4j
@Service
@RequiredArgsConstructor
public class JwtUserDetailsService implements UserDetailsService {

    private final UserService userService;

    @Override
    public UserDetails loadUserByUsername(String login) throws UsernameNotFoundException {

        User user = userService.findByLogin(login);

        JwtUser jwtUser = JwtUserFactory.create(user);
        log.info("IN loadUserByUsername - user with login: {} successfully loaded", login);
        return jwtUser;
    }
}

问题是你在注射什么东西 JwtTokenProvider 在一个 @Configuration 类，该类生成 JwtTokenProvider . 所以 JwtTokenProvider 需要安全配置提供的内容，而 SecurityConfig 只能在具有 JwtTokenProvider 因此循环依赖。
删除 @Component 从 JwtTokenProvider 创建一个 @Bean 中的方法 SecurityConfig （或不管它叫什么）创造了 JwtTokenProvider .
也不建议使用 @Bean 中的方法 @Components 所以把它移到 SecurityConfig 也。

@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter{

  @Bean
  public BCryptPasswordEncoder passwordEncoder() {
    return new BCryptPasswordEncoder(8);
  }

  @Bean
  public JwtTokenProvider jwtTokenProvider(UserDetailsService userDetailsService) {
    return new JwtTokenProvider(userDetailsService);
  }

  // other config
}

现在可能还有一个问题 JwtUserDetailsService 需要 UserService 这需要 PasswordEncoder 这又创建了一个循环引用。你最好注射 UserRepository 进入你的 JwtUserDetailsService 并使用它通过登录获取用户。我假设 UserService 只是代表 UserRepository.findByLogin 方法。

@Slf4j
@Service
@RequiredArgsConstructor
public class JwtUserDetailsService implements UserDetailsService {

    private final UserRepository userRepository;

    @Override
    public UserDetails loadUserByUsername(String login) throws UsernameNotFoundException {

        User user = userRepository.findByLogin(login);
        if (user != null) {
          JwtUser jwtUser = JwtUserFactory.create(user);
          log.info("IN loadUserByUsername - user with login: {} successfully loaded", login);
          return jwtUser;
        } else {
          throw new UsernameNotFoundException("Unknown user '"+login+"'");
        }
    }
}

注意：您的 UserDetailsService 未遵守合同（未找到任何用户应抛出 UsernameNotFoundException . 修改后的那个确实履行了那个合同。
