接受的答案对我使用 Oauth2 不起作用。经过一番研究,exception translator solution 起作用了。
基本上,您需要创建一个WebResponseExceptionTranslator 并将其注册为您的异常翻译器。
首先,创建一个WebResponseExceptionTranslator bean:
@Slf4j
@Configuration
public class Oauth2ExceptionTranslatorConfiguration {
@Bean
public WebResponseExceptionTranslator oauth2ResponseExceptionTranslator() {
return new DefaultWebResponseExceptionTranslator() {
@Override
public ResponseEntity<OAuth2Exception> translate(Exception e) throws Exception {
ResponseEntity<OAuth2Exception> responseEntity = super.translate(e);
OAuth2Exception body = responseEntity.getBody();
HttpStatus statusCode = responseEntity.getStatusCode();
body.addAdditionalInformation("timestamp", dateTimeFormat.format(clock.instant()))
body.addAdditionalInformation("status", body.getHttpErrorCode().toString())
body.addAdditionalInformation("message", body.getMessage())
body.addAdditionalInformation("code", body.getOAuth2ErrorCode().toUpperCase())
HttpHeaders headers = new HttpHeaders();
headers.setAll(responseEntity.getHeaders().toSingleValueMap());
// do something with header or response
return new ResponseEntity<>(body, headers, statusCode);
}
};
}
}
现在您需要更改 Oauth2 配置以注册 bean WebResponseExceptionTranslator:
@Slf4j
@Configuration
public class OAuth2Config extends AuthorizationServerConfigurerAdapter {
@Autowired
private AuthenticationManager authenticationManager;
@Autowired
private ClientDetailsServiceBuilder builder;
@Autowired
private WebResponseExceptionTranslator oauth2ResponseExceptionTranslator;
@Autowired
private UserDetailsService userDetailsService;
@Override
public void configure(ClientDetailsServiceConfigurer clients) {
clients.setBuilder(builder);
}
@Override
public void configure(AuthorizationServerEndpointsConfigurer endpoints) {
TokenEnhancerChain tokenEnhancerChain = new TokenEnhancerChain();
tokenEnhancerChain.setTokenEnhancers(
Arrays.asList(tokenEnhancer(), accessTokenConverter()));
endpoints.tokenStore(tokenStore())
.tokenEnhancer(tokenEnhancerChain)
.authenticationManager(authenticationManager)
.userDetailsService(userDetailsService)
.exceptionTranslator(oauth2ResponseExceptionTranslator);
}
}
最终结果将是:
{
"error": "unauthorized",
"error_description": "Full authentication is required to access this resource",
"code": "UNAUTHORIZED",
"message": "Full authentication is required to access this resource",
"status": "401",
"timestamp": "2018-06-28T23:55:28.86Z"
}
您可以看到我没有从OAuth2Exception 的原始正文中删除error 和error_description。我建议维护它们,因为这两个字段遵循 OAuth2 规范。请参阅the RFC 和OAuth2 API definitions 了解更多详情。
您还可以自定义结果:覆盖error或error_description(只需调用addAdditionalInformation),使用instance of识别特定异常以返回不同的json结果等。但也有限制:如果你想将某个字段定义为integer,我认为这是不可能的,因为addAdditionalInformation 方法只接受String 作为类型。
