不能处理Spring Security异常



我正在学习如何使用Spring Boot创建REST API，到目前为止一切都很顺利，但我遇到了我的第一个障碍:我无法处理使用Spring Security执行身份验证时抛出的异常。

我在我的项目中创建了一个ExceptionHandler类，用@ControllerAdvice注释，并且我能够使用SecurityFilterChain捕获应用程序中的不同异常，但是我了解到我无法捕获在身份验证期间抛出的异常，因为这些异常是在DispatcherServlet后面抛出的，并且在调用@ControllerAdvice之前。(源)

因此，我试图实现上面链接的教程中建议的解决方案之一，以处理Spring Security抛出的异常。我是这样做的:

  1. 我改变了我的SecurityFilterChain实现(下面的代码，在Kotlin中)添加authEntryPoint()方法。
  2. 我在下面的SecurityFilterChain实现中添加了.exceptionHandling { it.authenticationEntryPoint(authEntryPoint()) }行。

SecurityFilterChain实现
@Configuration
@EnableWebSecurity
class SecurityConfig(
private val certProperties: CertProperties,
@Qualifier("handlerExceptionResolver") private val resolver: HandlerExceptionResolver
) {
@Bean
fun securityFilterChain(http: HttpSecurity): SecurityFilterChain {
return http
.csrf().disable()
.authorizeRequests {
it.antMatchers("/v1/countries/**").authenticated()
}
.exceptionHandling { it.authenticationEntryPoint(authEntryPoint()) }
.sessionManagement { it.sessionCreationPolicy(SessionCreationPolicy.STATELESS) }
.oauth2ResourceServer { it.jwt() }
.httpBasic(Customizer.withDefaults())
.build()
}
private fun authEntryPoint() = AuthenticationEntryPoint { request, response, authException ->
// This code is never called
resolver.resolveException(request, response, null, authException)
}
@Bean
fun jwtDecoder() = JwtDecoder { token ->
val signedJwt = SignedJWT.parse(token)
val isValid = signedJwt.verify(ECDSAVerifier(certProperties.publicKey))
if (!isValid) throw UnauthorizedException(type = "AUTH_INVALID")
Jwt(
token,
signedJwt.jwtClaimsSet.issueTime.toInstant(),
signedJwt.jwtClaimsSet.expirationTime.toInstant(),
signedJwt.header.toJSONObject(),
signedJwt.jwtClaimsSet.toJSONObject()
)
}
}

RestExceptionHandler实现
@ControllerAdvice
class RestExceptionHandler {
@ExceptionHandler(value = [AuthenticationException::class])
fun handleApiException(ex: AuthenticationException): ResponseEntity<HttpException.Body> {
// This code is never called
val exception = UnauthorizedException(title = title, detail = detail)
return ResponseEntity(exception.body, exception.status)
}
}

但是，如果Spring Security在身份验证期间抛出异常(例如，JWT令牌无效，并且在上面的jwtDecoder()函数中调用了if条件)，则我上面所做的更改仍然无法捕获此异常:

既不调用SecurityConfig类中的方法authEntryPoint()，也不调用类RestExceptionHandler中的方法handleApiException()。所以，而不是看到我的自定义异常UnauthorizedException，我看到的是通用的春季启动异常。当Spring Security抛出异常时，我还在日志中看到以下堆栈跟踪:

有人知道为什么会发生这种情况吗?我在上面的代码中缺少什么，所以我可以正确捕获由Spring Security抛出的异常?谢谢!

问题(简而言之)是:com.learnspring.exception.UnauthorizedException是none of (noinstanceof):

org.springframework.security.core.AuthenticationException //! v5.7.3

(在这个认证阶段，使用您的特定过滤器+版本(BearerTokenAuthenticationFilter)，)这是由authenticationFailureHandler处理的异常类型(它应该指向您的特定入口点/处理程序…)，否则它将作为(常规)"servlet错误"处理;(在MVC处理程序/advice之前)。

修复在jwt解码器中抛出一个org.springframework.security.core.AuthenticationException。
