大家好，我是祁同伟，由于剧透的太多，都知道我是害死陈海的幕后元凶，所以我现在必须跑路了，由于资金被银行冻结所以现在发起众筹，等我跑到美国和丁义珍副市长重振雄风后，会给你一百万，为表示诚意，本人愿意奉上为赵立春省长父亲哭坟的视频一部。
本人亲身经历，不喜勿喷!
刚毕业的我到现在已经是第二次换工作了，前两个公司都是创业型公司，没有人来review我的代码，这就会让我写代码的会很随意、代码不是特别规范，逻辑不够那么的严谨（以后会说），今个儿就简单的说一说接口的规范和后台的写法。
我原先是使用JSONObject作为返回对象，前台需要什么就put什么，因为前端是就是我，我就是前段，所以接口这个问题就随便随便了，有的时候我也在想该把接口稍微整理一下，搞一个基类什么的，这样写法会得到统一使用的人（除我之外）也能很方便的使用。
最近花时间稍作整理（想找一些优秀的源码的话，直接去GitHub上去搜，切记切记切记）
再没有去动手之前，我思考一番，简单画了个草图
想法.png
基于思考去查找并加上验证，我创建了两个类
一个是返回基类BaseResp<T>
package com.quick.utils;
import java.util.Date;
/**
* @param <T>
*/
public class BaseResp<T> {
/**
* 返回码
*/
private int code;
/**
* 返回信息描述
*/
private String message;
/**
* 返回数据
*/
private T data;
private long currentTime;
public int getCode() {
return code;
}
public void setCode(int code) {
this.code = code;
}
public String getMessage() {
return message;
}
public void setMessage(String message) {
this.message = message;
}
public Object getData() {
return data;
}
public void setData(T data) {
this.data = data;
}
public long getCurrentTime() {
return currentTime;
}
public void setCurrentTime(long currentTime) {
this.currentTime = currentTime;
}
public BaseResp(){}
/**
*
* @param code 错误码
* @param message 信息
* @param data 数据
*/
public BaseResp(int code, String message, T data) {
this.code = code;
this.message = message;
this.data = data;
this.currentTime = new Date().getTime();
}
/**
* 不带数据的返回结果
* @param resultStatus
*/
public BaseResp(ResultStatus resultStatus) {
this.code = resultStatus.getErrorCode();
this.message = resultStatus.getErrorMsg();
this.data = data;
this.currentTime = new Date().getTime();
}
/**
* 带数据的返回结果
* @param resultStatus
* @param data
*/
public BaseResp(ResultStatus resultStatus, T data) {
this.code = resultStatus.getErrorCode();
this.message = resultStatus.getErrorMsg();
this.data = data;
this.currentTime = new Date().getTime();
}
}
一个是错误码枚举类ResultStatus，并且总结了一些常见的错误
package com.quick.utils;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
/**

private static final Logger LOGGER = LoggerFactory.getLogger(ResultStatus.class);

}
public static int getCode(String define){

public static String getMsg(int code){
for(ResultStatus err : ResultStatus.values()){

return err.msg;
}
}
return "errorCode not defined ";
}
public int getErrorCode(){
return code;
}
public String getErrorMsg(){

}
验证的结果如下
集合
map
字符串
这样写，既节省时间，也让别人看的舒服，用的开心
代码为api-norms
