我在Spring Data Rest Web应用程序中使用@RestResource
。我想自定义RestResource
的404错误。
我知道ControlerAdvice,处理程序...但是它与RestResource无关。
我已经尝试了很多东西:
我当前的源代码是:
@RestResource(path="user")
public interface UserRepository extends Repository<User, Long> {
User findById(Long id);
}
-
@EnableWebMvc
@ControllerAdvice
@Order(Ordered.HIGHEST_PRECEDENCE)
public class ErrorHandlerController extends ResponseEntityExceptionHandler {
@ExceptionHandler(ResourceNotFoundException.class)
ResponseEntity<?> handleNotFound(ResourceNotFoundException ex) {
ApiError apiError = new ApiError(HttpStatus.INTERNAL_SERVER_ERROR, "Internal server error");
return new ResponseEntity<>(apiError, apiError.getHttpStatus());
}
}
编辑1(我的问题不是重复的):
我也尝试像这样添加一个新的RestControllerAdviceHandler(但不起作用):
@RestControllerAdvice
public class RestControllerAdviceHandler {
@ExceptionHandler(Exception.class)
public ResponseEntity<String> defaultErrorHandler(HttpServletRequest req, Exception e) throws Exception {
return new ResponseEntity<>(" test ", HttpStatus.NOT_FOUND);
}
}
编辑2(关于spring框架源代码):
在对spring源代码进行了更多研究之后,我找到了下面的代码。似乎如果找不到实体,则不会引发异常,RestResource刚返回了一个新的ResponseEntity>(HttpStatus.NOT_FOUND))。也许用RestResource截取和自定义“未找到”错误是真的不可能吗?
/**
* <code>GET /{repository}/{id}</code> - Returns a single entity.
*
* @param resourceInformation
* @param id
* @return
* @throws HttpRequestMethodNotSupportedException
*/
@RequestMapping(value = BASE_MAPPING + "/{id}", method = RequestMethod.GET)
public ResponseEntity<Resource<?>> getItemResource(RootResourceInformation resourceInformation,
@BackendId Serializable id, final PersistentEntityResourceAssembler assembler, @RequestHeader HttpHeaders headers)
throws HttpRequestMethodNotSupportedException {
return getItemResource(resourceInformation, id).map(it -> {
PersistentEntity<?, ?> entity = resourceInformation.getPersistentEntity();
return resourceStatus.getStatusAndHeaders(headers, it, entity).toResponseEntity(//
() -> assembler.toFullResource(it));
}).orElseGet(() -> new ResponseEntity<Resource<?>>(HttpStatus.NOT_FOUND));
}
答案 0 :(得分:1)
该问题最终在Spring Data REST即将发布的3.2版中得到了解决。
抛出ResourceNotFoundException
异常,现在可以正确地拦截它。
您使用@ControllerAdvice
的解决方案将起作用。
在Spring Boot 2.2.0 M2和以下ExceptionHandler上进行了测试:
@ControllerAdvice
@Order(Ordered.HIGHEST_PRECEDENCE)
public class CustomRepositoryRestExceptionHandler {
@ExceptionHandler
ResponseEntity<?> handleNotFound(ResourceNotFoundException o_O) {
// Simply re-throw the exception and let the default handling kick in, which will produce a response body.
throw o_O;
}
}
正如评论中已经发布的那样,问题是https://jira.spring.io/browse/DATAREST-1143。
