为什么我尝试构建 JWT 令牌时会出现此异常？java.lang.NoClassDefFoundError: javax/xml/bind/DatatypeConverter

And*_*ili 1 java spring-security jwt spring-boot

我正在开发一个实现 JWT 身份验证的 Spring Boot 项目，但我发现了一些困难。它基于 Udemy 课程中发现的一个示例，我正在尝试适应我的特定用例。它由以下两个微服务组成：

GET-USER-WS：这是从数据库获取用户信息的微服务。
AuthServerJWT：此微服务调用GET-USER-WS来获取用户信息并构建将由其他微服务使用的 JWT 令牌。

基本上，第二个AuthServerJWT包含以下JwtAuthenticationRestController控制器类：

@RestController
//@CrossOrigin(origins = "http://localhost:4200")
public class JwtAuthenticationRestController  {

    @Value("${sicurezza.header}")
    private String tokenHeader;

    @Autowired
    private AuthenticationManager authenticationManager;

    @Autowired
    private JwtTokenUtil jwtTokenUtil;

    @Autowired
    @Qualifier("customUserDetailsService")
    private UserDetailsService userDetailsService;
    
    private static final Logger logger = LoggerFactory.getLogger(JwtAuthenticationRestController.class);

    @PostMapping(value = "${sicurezza.uri}")
    public ResponseEntity<?> createAuthenticationToken(@RequestBody JwtTokenRequest authenticationRequest)
            throws AuthenticationException {
        logger.info("Autenticazione e Generazione Token");

        authenticate(authenticationRequest.getUsername(), authenticationRequest.getPassword());

        final UserDetails userDetails = userDetailsService.loadUserByUsername(authenticationRequest.getUsername());

        final String token = jwtTokenUtil.generateToken(userDetails);
        
        logger.warn(String.format("Token %s", token));

        return ResponseEntity.ok(new JwtTokenResponse(token));
    }

    @RequestMapping(value = "${sicurezza.uri}", method = RequestMethod.GET)
    public ResponseEntity<?> refreshAndGetAuthenticationToken(HttpServletRequest request) 
            throws Exception 
    {
        String authToken = request.getHeader(tokenHeader);
        
        if (authToken == null || authToken.length() < 7)
        {
            throw new Exception("Token assente o non valido!");
        }
        
        final String token = authToken.substring(7);
        
        if (jwtTokenUtil.canTokenBeRefreshed(token)) 
        {
            String refreshedToken = jwtTokenUtil.refreshToken(token);
            
            return ResponseEntity.ok(new JwtTokenResponse(refreshedToken));
        } 
        else 
        {
            return ResponseEntity.badRequest().body(null);
        }
    }

    @ExceptionHandler({ AuthenticationException.class })
    public ResponseEntity<String> handleAuthenticationException(AuthenticationException e) 
    {
        return ResponseEntity.status(HttpStatus.UNAUTHORIZED).body(e.getMessage());
    }

    private void authenticate(String username, String password) 
    {
        Objects.requireNonNull(username);
        Objects.requireNonNull(password);

        try {   
            /// ???
            authenticationManager.authenticate(new UsernamePasswordAuthenticationToken(username, password));
        } 
        catch (DisabledException e) 
        {
            logger.warn("UTENTE DISABILITATO");
            throw new AuthenticationException("UTENTE DISABILITATO", e);
        } 
        catch (BadCredentialsException e) 
        {
            logger.warn("CREDENZIALI NON VALIDE");
            throw new AuthenticationException("CREDENZIALI NON VALIDE", e);
        }
    }
}

正如您所看到的，它包含两种方法：一种创建全新的 JWT 令牌，另一种刷新现有的 JWT 令牌。考虑用于创建新令牌的createAuthenticationToken() 。

在这一行：

final UserDetails userDetails = userDetailsService.loadUserByUsername(authenticationRequest.getUsername());

Run Code Online (Sandbox Code Playgroud)

它调用我的CustomUserDetailsService中定义的loadUserByUsername()方法。该方法基本上检索调用 ** GET-USER-WS服务的用户信息并构建一个UserDetails对象（即一个 Spring Security 对象，这个：org.springframework.security.core.userdetails.UserDetails）。

这是该方法的代码：

@Override public UserDetails loadUserByUsername(String UserId) throws UsernameNotFoundException { String ErrMsg = ""; if (UserId == null || UserId.length() < 2) { ErrMsg = "Nome utente assente o non valido"; logger.warn(ErrMsg); throw new UsernameNotFoundException(ErrMsg); } User user = this.GetHttpValue(UserId); if (user == null) { ErrMsg = String.format("User %s not found!!", UserId); logger.warn(ErrMsg); throw new UsernameNotFoundException(ErrMsg); } UserBuilder builder = null; builder = org.springframework.security.core.userdetails.User.withUsername(Integer.toString(user.getId())); builder.password(user.getPswd()); String[] operations = user.getUserTypes().stream() .map(UserType::getOperations) .flatMap(Set::stream) .map(Operation::getName) .distinct() .toArray(String[]::new); builder.authorities(operations); return builder.build(); }

此行仅执行GetHttpValue()方法，该方法用于执行 RestTemplate 调用，以检索包含用户详细信息的User对象：

User user = this.GetHttpValue(UserId);
Run Code Online (Sandbox Code Playgroud)
那么，回到前面的JwtAuthenticationRestController控制器类的第一个createAuthenticationToken()。我的问题是它在这一行检索此UserDetails userDetails对象：

final UserDetails userDetails = userDetailsService.loadUserByUsername(authenticationRequest.getUsername());
Run Code Online (Sandbox Code Playgroud)
使用调试器，这是我的userDetails实例的内容：

org.springframework.security.core.userdetails.User [Username=50, Password=[PROTECTED], Enabled=true, AccountNonExpired=true, credentialsNonExpired=true, AccountNonLocked=true, Granted Authorities=[ADMIN]]
Run Code Online (Sandbox Code Playgroud)
在我看来这是正确的（除了包含用户ID而不是用户名的用户名字段......我会第二次更改，这不应该是问题）。

然后它执行此行以便从该userDetails对象开始生成 JWT 令牌：

final String token = jwtTokenUtil.generateToken(userDetails);
Run Code Online (Sandbox Code Playgroud)
这是定义到名为JwtTokenUtil的类中的generateToken()方法的代码：

public String generateToken(UserDetails userDetails) { Map<String, Object> claims = new HashMap<>(); return doGenerateToken(claims, userDetails); }
Run Code Online (Sandbox Code Playgroud)
它首先创建一个空的 HashMap，然后调用doGenerateToken()，代码如下：

private String doGenerateToken(Map<String, Object> claims, UserDetails userDetails) { final Date createdDate = clock.now(); final Date expirationDate = calculateExpirationDate(createdDate); return Jwts.builder() .setClaims(claims) .setSubject(userDetails.getUsername()) .claim("authorities", userDetails.getAuthorities().stream().map(GrantedAuthority::getAuthority).collect(Collectors.toList())) .setIssuedAt(createdDate) .setExpiration(expirationDate) .signWith(SignatureAlgorithm.HS512, jwtConfig.getSecret().getBytes()) .compact(); }
Run Code Online (Sandbox Code Playgroud)
它正确创建了expirationDate日期。然后最后它抛出以下异常（使用调试器，在我看来，它是在compact()执行时抛出的）：问题是，当执行此行时，我得到以下异常：

为什么？我缺少什么？我该如何尝试解决这个问题？

我不知道为什么我会遇到这个问题，当我在 postgres 中运行代码时它工作正常，但我在 cassandra 中遇到了这个错误。

我刚刚将它们添加到我的 pom.xml 中
