Java 如何在TokenEndPoint Spring oAuth2中注入WebResponseExceptionTranslator

我试图定制Spring Security oAuth TokenEndpoint类处理异常的方式。我想返回一个比DefaultWebResponseExceptionTranslator当前更定制的JSON响应。我不知道如何通过XML注入自定义转换器。以下是我的代码片段：

spring-security.xml

<oauth:authorization-server
    client-details-service-ref="clientDetails" token-services-ref="tokenServices" 
    user-approval-handler-ref="userApprovalHandler" request-validator-ref="requestValidator" >
    <oauth:client-credentials />
    <oauth:password />
</oauth:authorization-server>

TokenEndpoint扩展了定义转换器的AbstractEndpoint

@FrameworkEndpoint
public class TokenEndpoint extends AbstractEndpoint {

    @ExceptionHandler(Exception.class)
    public ResponseEntity<OAuth2Exception> handleException(Exception e) throws Exception {
        logger.info("Handling error: " + e.getClass().getSimpleName() + ", " + e.getMessage());
        return getExceptionTranslator().translate(e);
    }

所以我的问题是。如何调用setProviderExceptionHandler通过我的spring security.xml传入我的自定义类？

为了自定义spring oauth的异常处理程序，您必须定义

WebResponseExceptionTranslator

的实例：

@Bean
public WebResponseExceptionTranslator webResponseExceptionTranslator() {
     return new DefaultWebResponseExceptionTranslator() {

         @Override
         public ResponseEntity<OAuth2Exception> translate(Exception e) throws Exception {
             ResponseEntity<OAuth2Exception> responseEntity = super.translate(e);
             OAuth2Exception body = responseEntity.getBody();
             HttpHeaders headers = new HttpHeaders();
             headers.setAll(responseEntity.getHeaders().toSingleValueMap());
             // do something with header or response
             return new ResponseEntity<>(body, headers, responseEntity.getStatusCode());
         }
     };
 }

只需检查基于xml配置的

可用的属性。

@bgme\u当通过xml配置授权服务器时，您有什么想法吗？您得到答案了吗？？？？

public class AbstractEndpoint implements InitializingBean {

   protected final Log logger = LogFactory.getLog(getClass());

   private WebResponseExceptionTranslator providerExceptionHandler = new DefaultWebResponseExceptionTranslator();

   public void setProviderExceptionHandler(WebResponseExceptionTranslator providerExceptionHandler) {
       this.providerExceptionHandler = providerExceptionHandler;
   }

@Bean
public WebResponseExceptionTranslator webResponseExceptionTranslator() {
     return new DefaultWebResponseExceptionTranslator() {

         @Override
         public ResponseEntity<OAuth2Exception> translate(Exception e) throws Exception {
             ResponseEntity<OAuth2Exception> responseEntity = super.translate(e);
             OAuth2Exception body = responseEntity.getBody();
             HttpHeaders headers = new HttpHeaders();
             headers.setAll(responseEntity.getHeaders().toSingleValueMap());
             // do something with header or response
             return new ResponseEntity<>(body, headers, responseEntity.getStatusCode());
         }
     };
 }

@Configuration
@EnableAuthorizationServer
public class OAuth2ServerConfiguration extends AuthorizationServerConfigurerAdapter {
    // some config

    @Override
    public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {
        endpoints
                .pathMapping("/oauth/authorize", "/authorize")
                .pathMapping("/oauth/error", "/error")
                .exceptionTranslator(webResponseExceptionTranslator())
        ;
    }
}
