当从restcontroller引发异常时，gradle构建的intellij和jar会产生不同的结果

Question

package refill.station.controller;

import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class TestController {

    @PostMapping("/test")
    public void test() {
        throw new NullPointerException("test Exception");
    }
}

我们可以看到相应的消息。此消息用作axios的警报消息！！

消息为空，错误是内部服务器错误！

Answer 1

为了获得唯一的响应消息，然后返回jax响应对象，而不是测试方法中的Void。这是一个示例代码。

import java.io.Serializable;
import javax.ws.rs.core.Response;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class TestController {
    @PostMapping("/test")
    public Response test() {
        MyResponse response = new MyResponse();
        try {
            processReqest();
        } catch (Exception ex) {
            response.setResponseText(ex.getMessage());
            return Response.ok(response).status(200).build();
        }
        return Response.ok(response).status(200).build();
    }

    private void processReqest() {
        throw new NullPointerException("test Exception");       
    }
}

class MyResponse implements Serializable{
    
    private static final long serialVersionUID = -3015657137609271996L;
    private String responseText;
    public String getResponseText() {
        return responseText;
    }
    public void setResponseText(String responseText) {
        this.responseText = responseText;
    }
}
