所以我们在项目开始初期就可以写一个工具类，来专门管理我们状态结果
比如
package com.javaxl.miaosha_02.result;
public class CodeMsg {
private int code;
private String msg;
//通用的错误码
public static CodeMsg SUCCESS = new CodeMsg(0, "success");
public static CodeMsg SERVER_ERROR = new CodeMsg(500100, "服务端异常");
public static CodeMsg BIND_ERROR = new CodeMsg(500101, "参数校验异常：%s");
//登录模块 5002XX
public static CodeMsg SESSION_ERROR = new CodeMsg(500210, "Session不存在或者已经失效");
public static CodeMsg PASSWORD_EMPTY = new CodeMsg(500211, "登录密码不能为空");
public static CodeMsg MOBILE_EMPTY = new CodeMsg(500212, "手机号不能为空");
public static CodeMsg MOBILE_ERROR = new CodeMsg(500213, "手机号格式错误");
public static CodeMsg MOBILE_NOT_EXIST = new CodeMsg(500214, "手机号不存在");
public static CodeMsg PASSWORD_ERROR = new CodeMsg(500215, "密码错误");
//订单模块 5004XX
public static CodeMsg ORDER_NOT_EXIST = new CodeMsg(500400, "订单不存在");
//秒杀模块 5005XX
public static CodeMsg MIAO_SHA_OVER = new CodeMsg(500500, "商品已经秒杀完毕");
public static CodeMsg REPEATE_MIAOSHA = new CodeMsg(500501, "不能重复秒杀");
private CodeMsg( ) {
}
private CodeMsg( int code,String msg ) {
this.code = code;
this.msg = msg;
}
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 CodeMsg fillArgs(Object... args) {
int code = this.code;
String message = String.format(this.msg, args);
return new CodeMsg(code, message);
}
@Override
public String toString() {
return "CodeMsg [code=" + code + ", msg=" + msg
在实际开发中如果项目比较大，甚至可以分模块来管理，每一个模块都专门写一个工具类来管理你的状态代码
