那些遇到过的问题

为什么 Java 中的 JWT 令牌无效或过期时，我的 CustomAuthenticationEntryPoint 开始方法没有被调用？

lil*_*hit 3 java spring-security jwt spring-resource-server

当 jwt 令牌无效或过期时，为什么不调用此开始方法？当令牌为空时会调用它。奇怪的是，在调试时我发现当令牌无效或过期时，会调用 BearerTokenAuthenticationEntryPoint.commence() 方法。这个类是标准java库的一部分，并且是最终的，所以不能扩展。但它实现了与我实现相同的接口 - AuthenticationEntryPoint，但我的开始方法仍然没有被调用。仅当令牌为空时才会调用它。

public class CustomAuthenticationEntryPoint implements AuthenticationEntryPoint {
  public CustomAuthenticationEntryPoint() {
  }

  @Override
  public void commence(HttpServletRequest httpServletRequest, HttpServletResponse response, AuthenticationException authenticationException) throws IOException {
    response.setContentType(MediaType.APPLICATION_JSON_VALUE);
    response.setStatus(HttpServletResponse.SC_UNAUTHORIZED);
    HttpStatus status = HttpStatus.UNAUTHORIZED;

    final Map<String, Object> body = new HashMap<>();
    body.put("status", status.name());
    body.put("statusCode", status.value());
    body.put("message", "You need to login first in order to perform this action");

    final ObjectMapper mapper = new ObjectMapper();
    mapper.writeValue(response.getOutputStream(), body);
  }
}

我这样使用它：

@Bean
public SecurityFilterChain securityFilterChain(HttpSecurity http) throws Exception {
    http
            .authorizeHttpRequests((authorize) -> authorize
                .requestMatchers("/api/v1/auth/**").permitAll() 
                .requestMatchers("/api/v1/admin/**").hasAuthority(Authority.ADMIN.name())
                .anyRequest().authenticated()
            )
        .csrf().disable()
        .cors().disable()
        .httpBasic().disable()
        .oauth2ResourceServer((oauth2) ->
            oauth2.jwt((jwt) -> jwt.jwtAuthenticationConverter(jwtToUserConverter))
        )
        .sessionManagement((session) -> session.sessionCreationPolicy(SessionCreationPolicy.STATELESS))
        .exceptionHandling((exceptions) -> exceptions
            .authenticationEntryPoint(new CustomAuthenticationEntryPoint())
            .accessDeniedHandler(new CustomAccessDeniedHandler())
        );
    return http.build();

我尝试实现 AuthenticationEntryPoint 并期望在令牌无效或过期时调用我的start() 方法。但我的 begin() 方法没有被调用，而是 BearerTokenAuthenticationEntryPoint.commence() 方法被调用。

这是我的 JwtToUserConverter：

@Component
public class JwtToUserConverter implements Converter<Jwt, UsernamePasswordAuthenticationToken> {
    @Override
    public UsernamePasswordAuthenticationToken convert(Jwt jwt) {
        // extract user information from the JWT
        String username = jwt.getSubject();
        List<LinkedTreeMap> authoritiesList = jwt.getClaim("authorities");

        // create a collection of SimpleGrantedAuthority objects
        Collection<SimpleGrantedAuthority> grantedAuthorities = authoritiesList.stream()
            .map(authority -> new SimpleGrantedAuthority((String) authority.get("role")))
            .collect(Collectors.toList());

        // create the UsernamePasswordAuthenticationToken
        return new UsernamePasswordAuthenticationToken(username, null, grantedAuthorities);
    }

}

根据您的日志，BearerAuthenticationEntryPoint正在从第 77行调用：

at org.springframework.security.oauth2.server.resource.web.authentication.BearerTokenAuthenticationFilter.lambda$new$0(BearerTokenAuthenticationFilter.java:77)
Run Code Online (Sandbox Code Playgroud)

这是该authenticationFailureHandler字段，然后调用AuthenticationEntryPoint. 如果我没记错的话，oauth2ResourceServerDSL 不会使用相同的AuthenticationEntryPointfrom exceptionHandling()，因此您必须显式配置它，如下所示：
