Spring Rest异常处理程序返回XML格式(Spring Rest exception handler return XML format)

 我在我的项目中处理异常 
 
 这是我的GET端点： 
 
@RequestMapping(method = RequestMethod.GET)
public ResponseEntity<V6SubnetRec> get(@RequestBody V6SubnetRequest requestBody) throws QIPException {
    Site site = getSite(requestBody.getOrganization());
    V6SubnetRec wsSubnet = (V6SubnetRec) requestBody.getV6Subnet();
    V6SubnetRec v6SubnetRec = null;
    try {
        v6SubnetRec = getQipService1().getV6Subnets(wsSubnet, site);
    } catch (Exception e) {
        log.error(Keys.QIP_CALLOUT_ERROR, e);
        throw new RestException(e);
    }
    return new ResponseEntity<V6SubnetRec>(v6SubnetRec, HttpStatus.OK);
}

@ExceptionHandler(RestException.class)
public ResponseEntity rulesForRestException(RestException restEx){
    return new ResponseEntity(restEx.getResponse().getContent(), restEx.getResponse().getStatus());
}
 
 RestException.java 
 
@XmlRootElement(name = "RestException")
@XmlAccessorType(XmlAccessType.FIELD)
public class RestException extends RuntimeException{

   @XmlElement
   RestResponse response;

   public RestException(Exception e){
     //...
   }
}
 
 当我使用URL http：//localhost/api/v1/v6subnet.json （以JSON格式返回）请求时，它将返回HTTP状态代码404并包含内容。 没关系。  
 
 但是，当我使用相同的请求请求URL http：//localhost/api/v1/v6subnet.xml （以XML格式返回）时，它返回HTTP状态代码500，就像正常异常一样，不作为JSON格式处理 
 
  
 
 我希望得到像我请求JSON格式时的结果。 
 
 谢谢。 

I'm handling an exception in my project
 
This is my GET endpoint:
 
@RequestMapping(method = RequestMethod.GET)
public ResponseEntity<V6SubnetRec> get(@RequestBody V6SubnetRequest requestBody) throws QIPException {
    Site site = getSite(requestBody.getOrganization());
    V6SubnetRec wsSubnet = (V6SubnetRec) requestBody.getV6Subnet();
    V6SubnetRec v6SubnetRec = null;
    try {
        v6SubnetRec = getQipService1().getV6Subnets(wsSubnet, site);
    } catch (Exception e) {
        log.error(Keys.QIP_CALLOUT_ERROR, e);
        throw new RestException(e);
    }
    return new ResponseEntity<V6SubnetRec>(v6SubnetRec, HttpStatus.OK);
}

@ExceptionHandler(RestException.class)
public ResponseEntity rulesForRestException(RestException restEx){
    return new ResponseEntity(restEx.getResponse().getContent(), restEx.getResponse().getStatus());
}
 
RestException.java
 
@XmlRootElement(name = "RestException")
@XmlAccessorType(XmlAccessType.FIELD)
public class RestException extends RuntimeException{

   @XmlElement
   RestResponse response;

   public RestException(Exception e){
     //...
   }
}
 
When I request with URL http://localhost/api/v1/v6subnet.json (return with JSON format), it will return HTTP status code 404 and include the content. It's OK. 
 
But when I request with URL http://localhost/api/v1/v6subnet.xml (return with XML format) with the same request, it return HTTP status code 500 like a normal exception which is not handled as JSON format
 
 
I want to have results like when I request to JSON format.
 
Thanks.
