bean可以改/
package com.example.uploaderpicture; public class Bean { /** * msg : 天呢！文件不能为空 * code : 1 */ private String msg; private String code; public String getMsg() { return msg; } public void setMsg(String msg) { this.msg = msg; } public String getCode() { return code; } public void setCode(String code) { this.code = code; } }
