Spring Boot RestController，错误状态响应主体，错误消息为空

在我的 Spring Boot RestController 上，我想通过抛出自定义异常来将自定义错误消息传递到响应正文。我正在遵循指南https://dzone.com/articles/spring-rest-service-exception-handling-1 https://dzone.com/articles/spring-rest-service-exception-handling-1

这些是我的代码片段：

用户未发现异常

import org.springframework.http.HttpStatus;
import org.springframework.web.bind.annotation.ResponseStatus;


@ResponseStatus(HttpStatus.NOT_FOUND)
public class UserNotFoundException extends RuntimeException {
    public UserNotFoundException(String message) {
        super(message);
    }
}

简化的 RestController

@RestController
public class CreateRfqController {

    @PostMapping("api/create-rfq")
    public ResponseEntity<Rfq> newRfq(@RequestBody Rfq newRfq) {
        throw new UserNotFoundException("User Not Found");
    }
}

当调用我的 Rest API 时，我总是收到一条空消息：

{
    "timestamp": "2020-06-24T18:23:30.846+00:00",
    "status": 404,
    "error": "Not Found",
    "message": "",
    "path": "/api/create-rfq"
}

相反我想要"message": "User Not Found",

在某个阶段我什至让它发挥作用。看来我在某些方面搞砸了。

在日志中，您甚至可以看到“找不到用户”文本和正确的异常类

我的构建.gradle

    implementation 'org.springframework.boot:spring-boot-starter-web'
    testImplementation('org.springframework.boot:spring-boot-starter-test') {
        exclude group: 'org.junit.vintage', module: 'junit-vintage-engine'
    }

更新： 我故意将一些错误的变量类型传递到我的 RFQ 对象中以产生默认错误。 即使在响应中，消息也是空的：

{
    "timestamp": "2020-06-24T19:20:18.831+00:00",
    "status": 403,
    "error": "Forbidden",
    "message": "",
    "path": "/api/create-rfq"
}

Spring Boot 2.3.0 中的行为已更改。改变属性server.error.include-message = 始终在您的 application.properties/yml 文件中。
