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，我正在尝试设置自定义错误消息.但是由于某种原因，错误的message没有显示出来.

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");
    }

}

这是我得到的回复:

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

我正在传递一个 JSON，但我没有验证任何内容，我只是想设置自定义消息.如果我更改状态代码，我会在响应中看到它，但 message 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.

为什么这不像预期的那样工作?这是一个如此简单的例子，我看不出可能遗漏了什么.当我调试代码时，我可以看到错误消息设置了所有字段.但由于某种原因，消息从未在响应中设置.

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，您需要做的就是将 server.error.include-message=always 添加到您的 application.properties 文件中，现在您的消息字段应该被填充.

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.

此行为在 Spring Boot 2.3 中已更改，您可以在此处阅读:https://github.com/spring-projects/spring-boot/wiki/Spring-Boot-2.3-Release-Notes#changes-to-the-default-error-pages-content
