Spring Boot关于Rest Api前后端分离404、500全局异常处理

1、自定义返回json格式

/**
 * Created by 菜园子 on 2019/3/25.
 */
public class Result {
    private int code;//0请求失败;1请求成功;其它服务异常
    private String msg;
    private Object data;

    public Result() {
        this.code = 0;
        this.msg = "请求失败";
        this.data = null;
    }

    public int getCode() {
        return code;
    }

    public void setCode(int code) {
        this.code = code;
    }

    public String getMsg() {
        return msg;
    }

    public void setMsg(String msg) {
        this.msg = msg;
    }

    public Object getData() {
        return data;
    }

    public void setData(Object data) {
        this.data = data;
    }
}

2、定义异常处理类

/**
 * Created by 菜园子 on 2019/3/25.
 * 全局404/500异常捕捉处理工具
 */
@ControllerAdvice
public class GlobalExceptionHandler {
    @ExceptionHandler
    @ResponseBody
    public Result defaultErrorHandler(HttpServletRequest request,Exception e){
        Result result = new Result();
        result.setMsg(e.getMess
