404 状态而不是返回令牌！为什么？

Question

我正在使用 Hibernate 和 Spring Boot 编写 Spring MVC 应用程序。我决定将 Spring 安全与 JWT 连接起来。我根据教程完成了所有操作，但结果我没有 returning 令牌，而是获得了 404 状态。为什么？以及如何修复它？

配置：

@Configuration
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Autowired
    public void setJwtTokenProvider(JwtTokenProvider jwtTokenProvider) {
        this.jwtTokenProvider = jwtTokenProvider;
    }

    // Fields
    //
    private JwtTokenProvider jwtTokenProvider;

    //


    @Bean
    @Override
    public AuthenticationManager authenticationManagerBean() throws Exception {
        return super.authenticationManagerBean();
    }


    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
                .cors().disable().csrf().disable()
                .httpBasic().disable()
                .sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS)
                .and()
                .authorizeRequests()
                .antMatchers("/auth/login").permitAll()
                .anyRequest().authenticated()
                .and()
                .apply(new JwtConfigurer(jwtTokenProvider));
    }
}

控制器：

@RequiredArgsConstructor
@RestController(value = "/auth")
public class AuthenticationController {

    // Fields
    //
    private final AuthenticationManager authenticationManager;

    private final JwtTokenProvider jwtTokenProvider;

    private final UserService userService;
    //


    // GET-Methods
    //
    //
    @PostMapping("/login")
    public ResponseEntity<Map<String, String>> login(@RequestBody AuthenticationRequestDTO requestDto) {
        try {
            String login = requestDto.getLogin();
            authenticationManager
                    .authenticate(new UsernamePasswordAuthenticationToken(login, requestDto.getPassword()));

            User user = userService.findByLogin(login);

            String token = jwtTokenProvider.createToken(login, user.getRole());

            Map<String, String> response = new HashMap<>();
            response.put("login", login);
            response.put("token", token);

            return ResponseEntity.ok(response);

        } catch (AuthenticationException e) {
            throw new BadCredentialsException("Invalid login or password");
        }
    }
}

JwtTokenProvider:

@Component
public class JwtTokenProvider {

    // Fields
    //
    private final UserDetailsService userDetailsService;

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

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


    // METHODS
    //
    /**
     * BCrypt
     */
    @Bean
    public BCryptPasswordEncoder passwordEncoder() {
        return new BCryptPasswordEncoder(8);
    }


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

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

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

        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);

            if (claims.getBody().getExpiration().before(new Date())) {
                return false;
            }
            return true;

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


    public String resolveToken(HttpServletRequest req) {
        String bearerToken = req.getHeader("Authorization");
        if (bearerToken != null && bearerToken.startsWith("Bearer_")) {
            return bearerToken.substring(7, bearerToken.length());
        }
        return null;
    }


    private String getRoleName(Role role) {

        String roleName = role.name();

        return roleName;
    }
}

P.S。根据数据库中的条目，我输入了正确的 password 和 login。如果我输入另一个 link，它将 return 403.

(所以问题是我连这个断点都没有过！不到那个地方怎么过啊！报404错误)

如果您没有使用 tomcat 嵌入式，请尝试在您的网址前添加项目名称。前任： http://localhost:8080/project-name/auth/login
