3、JSON封装体CommonResult

package com.wzy.springcloud.Entities;
import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
@Data //Getter、Setter
@AllArgsConstructor //全参构造器
@NoArgsConstructor //无参构造器
public class CommonResult<T> {
    private Integer code;
    private String message;
    private T data;
    public CommonResult(Integer code, String message){
        this(code, message, null);
    }
}
