Spring ResponseStatusException不返回原因 [英] Spring ResponseStatusException does not return reason

问题描述

我有一个非常简单的 @RestController ，并且我试图设置一个自定义错误消息。但是由于某种原因，错误的消息没有显示。

I have a very simple @RestController, and I'm trying to set a custom error message. But for some reason, the message for the error is not showing up.

这是我的控制器：

@RestController
@RequestMapping("openPharmacy")
public class OpenPharmacyController {


    @PostMapping
    public String findNumberOfSurgeries(@RequestBody String skuLockRequest) {
        throw new ResponseStatusException(HttpStatus.BAD_REQUEST, "This postcode is not valid");
    }

}

这是我得到的答复：

{
    "timestamp": "2020-06-24T17:44:20.194+00:00",
    "status": 400,
    "error": "Bad Request",
    "message": "",
    "path": "/openPharmacy/"
}

我正在传递JSON，但我没有进行任何验证，我只是在尝试设置自定义消息。如果更改状态代码，则会在响应中看到该消息，但是消息始终为空。

I'm passing a JSON, but I'm not validating anything, I'm just trying to set the custom message. If I change the status code, I see that on the response, but the message is always empty.

为什么这不起作用像预期的那样？这是一个非常简单的示例，我看不到可能遗漏的内容。当我调试代码时，我可以看到错误消息设置了所有字段。但是由于某些原因，该消息永远不会在响应中设置。

Why is this not working like expected? This is such a simple example that I can't see what may be missing. When I debug the code I can see that the error message has all the fields set. But for some reason, the message is never set on the response.

基本上，您所需要做的就是添加 server.error.include-message = always 到application.properties文件，现在应该填充您的消息字段。

Basically, all you need to do is add server.error.include-message=always to your application.properties file, and now your message field should be populated.

此行为已在Spring Boot 2.3中更改，您可以在此处阅读： a href = https://github.com/spring-projects/spring-boot/wiki/Spring-Boot-2.3-Release-Notes#changes-to-the-default-error-pages-content rel = noreferrer > https://github.com/spring-projects/spring-boot/wiki/Spring-Boot-2.3-Release-Notes#changes-to-the-default-error-pages-content

This behavior was changed in Spring Boot 2.3 which you can read about here: https://github.com/spring-projects/spring-boot/wiki/Spring-Boot-2.3-Release-Notes#changes-to-the-default-error-pages-content
