即使我已将其指定为在遇到此异常时在处理程序（HttpStatus.INTERNAL_SERVER_ERROR）中返回500，异常处理程序仍将返回200响应。
我正在使用Spring Boot v1.5.4.RELEASE。
我正在调用Spring Boot服务并返回JSON对象。我正在使用自定义异常处理程序。
在反序列化期间发生EntityNotFoundException时，它不返回500响应，而是返回200响应并将错误嵌入到主体输出中。这是由于数据错误导致的，因为外键无效，因此在数据库中找不到ManyToOne关系。
请注意，我正在使用本机查询来提取实体。
@Entity
@Table(name = "PARENT_ENTITY")
public class ParentEntity {
@JsonView({MyViews.ParentEntity.class})
@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name="CHILD_KEY")
protected ChildEntity childKey;
}
如何做到这一点，以便该服务返回500响应而不是200？
代码示例：
@ControllerAdvice
public class RestExceptionHandler extends ResponseEntityExceptionHandler{
@ExceptionHandler(EntityNotFoundException.class)
@ResponseStatus(value = HttpStatus.INTERNAL_SERVER_ERROR, reason = "INTERNAL_SERVER_ERROR")
protected ResponseEntity<Object> handleEntityNotFoundException(EntityNotFoundException ex) {
ApiError apiError = new ApiError(HttpStatus.INTERNAL_SERVER_ERROR);
apiError.setMessage(ex.getMessage());
apiError.setStackTrace(StringUtil.jsonEscapeNewlines(ExceptionUtils.getStackTrace(ex)));
return new ResponseEntity<>(apiError, apiError.getStatus())
}
}
服务的示例输出：
响应码：200

我想知道您的请求是否由同一个异常处理程序处理。
您已将用户消息设置为“数据问题”，但输出响应将其显示为null。
apiError.setUserMessage("Data issue:" + ex.getMessage());
//based on your code it should have at least "Data issue:"
"userMessage": null,
请确保验证您发布的代码是否作为此请求的一部分被调用。当然，您可以添加一条日志消息以确认相同。如果您能够在本地复制问题，则可以保留一个断点并确认是否调用了相同的异常处理程序。

您可以通过在查询中进行内部联接来避免未找到实体错误。下面的示例使用本机查询格式。这更像是一种解决方法，但足以解决我的情况。我现在将其标记为答案。
select pe.* from PARENT_ENTITY pe
inner join CHILD_ENTITY ce on pe.CHILD_KEY = ce.rowid_org_cust
