## 3.5 创建接口定义返回码
“`java
public interface ResultCode {
public static Integer SUCCESS = 20000;
public static Integer E Rr OR = 20001;
}
“`
## 3.5 创建统一结果返回类
“`java
@Data
public class R {
//是否成功
private Boolean success;
//返回码
private Integer code;
//返回消息
private String message;
//返回数据
private Map<String, Object > data = new HashMap <String, Object>();
private R(){};
public static R ok(){
R r = new R();
r.setSuccess(true);
r.setCode(ResultCode.SUCCESS);
r.setMessage(“成功”);
return r;
}
public static R error(){
R r = new R();
r.setSuccess(true);
r.setCode(ResultCode.ERROR);
r.setMessage(“失败”);
return r;
}
public R success(Boolean success){
this.setSuccess(success);
return this;
}
public R message(String message){
this.setMessage(message);
return this;
}
public R code(Integer code){
this.setCode(code);
return this;
}
public R data(String key, Object value){
this.data.put(key, value);
return this;
}
public R data(Map<String, Object> map){
this.setData(map);
return this;

## 3.6 创建utils包下的 random Util
“`java
package com.demo.ali service .utils;
import java.text.DecimalFormat;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Random;
/**
* 获取随机数
*
* @author qianyi
*
*/
public class RandomUtil {
private static final Random random = new Random();
private static final DecimalFormat fourdf = new DecimalFormat(“0000”);
private static final DecimalFormat sixdf = new DecimalFormat(“000000”);
public static String getFourBitRandom() {
return fourdf.format(random.nextInt(10000));
}
public static String getSixBitRandom() {
return sixdf.format(random.nextInt(1000000));
}
/**
* 给定数组，抽取n个数据
* @param list
* @param n
* @return
*/
public static ArrayList getRandom(List list, int n) {
Random random = new Random();
HashMap<Object, Object> hashMap = new HashMap<Object, Object>();
// 生成随机数字并存入HashMap
for (int i = 0; i < list.size(); i++) {
int number = random.nextInt(100) + 1;
hashMap.put(number, i);
}
// 从HashMap导入数组
Object[] robjs = hashMap.values().toArray();
ArrayList r = new ArrayList();
// 遍历数组并打印数据
for (int i = 0; i < n; i++) {
int position = Integer.parseInt(String.valueOf(robjs[i]));
r.add(list.get(position));
}
return r;
}
}

## 3.7 创建servie接口和service的实现类
service接口
“`java
public interface AliService {
boolean send(Map<String, Object> param, String phone);
}
“`
service的实现了
“`java
@Service
public class AliServiceImpl implements AliService {
public boolean send(Map<String, Object> param, String phone) {
if(StringUtils.isEmpty(phone)) return false;
/**
参数一，default
参数二，阿里云的AccessKeyID
参数三，阿里云的AccessKeySecret：
**/
DefaultProfile profile =
DefaultProfile.getProfile(“default”, “LTAaASQDF1CGTEEFGUXZHMA”, “WRTSbya6qe1SDS6qwe13aWSH0”);
IAcsClient client = new DefaultAcsClient(profile);
//设置相关固定的参数
Common request request = new CommonRequest();
//request.setProtocol(ProtocolType.HTTPS);
request.setMethod(MethodType.POST);
request.setDomain(“dysmsapi.aliyuncs.com”);
request.setVersion(“2017-05-25”);
request.setAction(“SendSms”);
//设置发送相关的参数
request.putQueryParameter(“PhoneNumbers”,phone); //手机号
request.putQueryParameter(“SignName”,”我的xxx在线网站”); //申请阿里云 签名名称
request.putQueryParameter(“TemplateCode”,”SMS_139315701″); //申请阿里云 模板code
request.putQueryParameter(“TemplateParam”, JSONObject.toJSONString(param)); //验证码数据，转换json数据传递
try {
//最终发送
CommonResponse response = client.getCommonResponse(request);
boolean success = response.getHttpResponse().isSuccess();
return success;
}catch(Exception e) {
e.printStackTrace();
return false;
}
}
}
“`
## 3.8 创建控制器controller
“`java
@RestController
@RequestMapping(“/msm”)
public class AliController {
@Autowired
private AliService aliService;
@Autowired
private RedisTemplate<String,String> redisTemplate;
@GetMapping(“send/{phone}”)
public R sedMsm(@PathVariable String phone){
// 1. 从redis中获取验证码，获取不到就发送
String code1 = redisTemplate.opsForValue().get(phone);
if(!StringUtils.isEmpty(code1)){
return R.ok();
}
//生成随机值，传递阿里云进行发送
String code = RandomUtil.getFourBitRandom();
Map<String,Object> param = new HashMap<String,Object>();
param.put(“code”,code);
boolean isSend = aliService.send(param,phone);
if(isSend){
//发送成功，把成功的验证码放到redis中，设置有效时间
redisTemplate.opsForValue().set(phone,code,5, TimeUnit.MINUTES);
return R.ok();
}else{
return R.error().message(“短信发送失败”);
}
}
}
