【springboot】springboot实现短信验证功能:

---

一、开通阿里云短信服务：

二、springboot配置：

【1】pom.xml

<dependency>
	<groupId>com.aliyun</groupId>
	<artifactId>aliyun-java-sdk-core</artifactId>
	<version>4.5.16</version>
</dependency>
<dependency>
	<groupId>com.aliyun</groupId>
	<artifactId>aliyun-java-sdk-dysmsapi</artifactId>
	<version>1.0.0</version>
</dependency>

【2】utils=>ValidateCodeUtils

package com.example.ruijiwaimai.utils;

import java.util.Random;

/**
 * 随机生成验证码工具类
 */
public class ValidateCodeUtils {
    
    
    /**
     * 随机生成验证码
     * @param length 长度为4位或者6位
     * @return
     */
    public static Integer generateValidateCode(int length){
    
    
        Integer code =null;
        if(length == 4){
    
    
            code = new Random().nextInt(9999);//生成随机数，最大为9999
            if(code < 1000){
    
    
                code = code + 1000;//保证随机数为4位数字
            }
        }else if(length == 6){
    
    
            code = new Random().nextInt(999999);//生成随机数，最大为999999
            if(code < 100000){
    
    
                code = code + 100000;//保证随机数为6位数字
            }
        }else{
    
    
            throw new RuntimeException("只能生成4位或6位数字验证码");
        }
        return code;
    }

    /**
     * 随机生成指定长度字符串验证码
     * @param length 长度
     * @return
     */
    public static String generateValidateCode4String(int length){
    
    
        Random rdm = new Random();
        String hash1 = Integer.toHexString(rdm.nextInt());
        String capstr = hash1.substring(0, length);
        return capstr;
    }
}

【3】utils=>ValidateCodeUtils

package com.example.ruijiwaimai.utils;

import com.aliyuncs.DefaultAcsClient;
import com.aliyuncs.IAcsClient;
import com.aliyuncs.dysmsapi.model.v20170525.SendSmsRequest;
import com.aliyuncs.dysmsapi.model.v20170525.SendSmsResponse;
import com.aliyuncs.exceptions.ClientException;
import com.aliyuncs.profile.DefaultProfile;

/**
 * 短信发送工具类
 */
public class SMSUtils {
    
    

	/**
	 * 发送短信
	 * @param signName 签名
	 * @param templateCode 模板
	 * @param phoneNumbers 手机号
	 * @param param 参数
	 */
	public static void sendMessage(String signName, String templateCode,String phoneNumbers,String param){
    
    
		//DefaultProfile profile = DefaultProfile.getProfile("cn-hangzhou", "LTAI5tJwSFUW3drsWucPX5N3", "75ng3hDMhDoJbciXPGnZjDkEiZaptd");
		DefaultProfile profile = DefaultProfile.getProfile("cn-hangzhou", "<your-accessKeyId>", "<your-accessKeySecret>");
		IAcsClient client = new DefaultAcsClient(profile);

		SendSmsRequest request = new SendSmsRequest();
		request.setSysRegionId("cn-hangzhou");
		request.setPhoneNumbers(phoneNumbers);
		request.setSignName(signName);
		request.setTemplateCode(templateCode);
		request.setTemplateParam("{
    
    \"code\":\""+param+"\"}");
		try {
    
    
			SendSmsResponse response = client.getAcsResponse(request);
			System.out.println("短信发送成功");
		}catch (ClientException e) {
    
    
			e.printStackTrace();
		}
	}
}

【4】发送验证码接口：

import org.springframework.web.bind.annotation.RestController;

import javax.servlet.http.HttpSession;
import java.util.Map;

@RestController
@Slf4j
@RequestMapping("/user")
public class UserController {
    
    
    @Autowired
    private UserService userService;

    @PostMapping("/sendMsg")
    public Result<String> sendMsg(@RequestBody User user, HttpSession session){
    
    
        //获取手机号
        String phone= user.getPhone();
        if (StringUtils.isNotEmpty(phone)){
    
    
            //生成随机验证码
            String code = ValidateCodeUtils.generateValidateCode(4).toString();
            //调用短信API,发送短信服务
            log.info("手机号为:{},验证码为:{}",phone,code);
            SMSUtils.sendMessage("阿里云短信测试","SMS_154950909",  phone,code);
			// SMSUtils.sendMessage("","", phone,code);

            session.setAttribute(phone,code);
            return Result.success("手机验证码短信发送成功");
        }
        return Result.error("手机号不能为空,短信发送失败");
    }

    @PostMapping("/login")
    public Result<User> login(@RequestBody Map map, HttpSession session){
    
    
        log.info(map.toString());
        //获取手机号
        String phone = map.get("phone").toString();
        //获取验证码
        String code = map.get("code").toString();
        //从Session中获取保存的验证码
        Object codeInSession = session.getAttribute(phone);
        //验证码比对
        if (codeInSession!=null&&codeInSession.equals(code)){
    
    
            //比对成功，登录成功
            LambdaQueryWrapper<User> queryWrapper=new LambdaQueryWrapper<>();
            queryWrapper.eq(User::getPhone,phone);
            User user=userService.getOne(queryWrapper);
            if (user == null) {
    
    
                //新用户=》自动完成注册
                user=new User();
                user.setPhone(phone);
                userService.save(user);
            }
            session.setAttribute("user",user.getId());
            return Result.success(user);
        }
        return Result.error("验证码失效了");
    }
}
