Springboot @ResponseStatus message为null

现象：

代码中我们使用@ResponseStatus要返回自定义的异常message，但是接口返回的message为null

   		if (null == db) {
            throw new NotExist("conductorEnv not exist");
        }

@ResponseStatus(HttpStatus.BAD_REQUEST)
public class BadRequest extends RuntimeException{
    public BadRequest(String message, Exception exception) {
        super(message, exception);
    }
    public BadRequest(String message) {
        super(message);
    }
    public BadRequest() {
        super("Bad Request: please check your request body.");
    }
}

{
    "timestamp": 1656905642972,
    "status": 404,
    "error": "Not Found",
    "message": "",
    "path": "/api/v1/workflow/clusters/CID-87/conductor/env/update/CID-787"
}

解决办法

从SpringBoot 2.3+开始，引入了一下新的属性来控制message
https://github.com/spring-projects/spring-boot/wiki/Spring-Boot-2.3-Release-Notes#new-and-noteworthy

我们要做的是在配置文件中加入

server:
  error:
    include-message: always
