Spring Data redis和amqpRebbitmq笔记

springboot + springcloud基本配置

application.yml:

spring:
  application:
    name: user-service
  datasource:
    url: jdbc:mysql://127.0.0.1:3306/leyou
    username: root
    password: 12345
    driver-class-name: com.mysql.jdbc.Driver
  redis:
    host: 127.0.0.1

redis的使用：

（1）引入spring data redis依赖
（2）注入StringRedisTemplate：

 @Autowired
 private StringRedisTemplate redisTemplate;

（3）调用该类中的方法：

//把验证码保存到redis中（5分钟）
this.redisTemplate.opsForValue().set(KEY_PREFIX + phone, 123456, code, 5, TimeUnit.MINUTES);

RabbitMQ的使用：

（1）引入spring data amqp依赖
（2）注入AmqpTemplate：

@Autowired
private AmqpTemplate amqpTemplate;

（3）生产者（有生产者就必须要有消费者）：

//发送消息到rabbitMQ
HashMap<String, String> msg = new HashMap<>();
msg.put("phone", phone);
msg.put("code", code);
amqpTemplate.convertAndSend("leyou.sms.exchange", "verifycode.sms", msg);

（4）消费者（一旦监听到有exchange和key跟该方法上注解保持一致，就直接执行该方法）：

@Component
public class SmsListener {

    @Autowired
    private SmsUtils smsUtils;

    @Autowired
    private SmsProperties smsProperties;

    @RabbitListener(bindings = @QueueBinding(
            value = @Queue(value = "leyou.sms.queue", durable = "true"),
            exchange = @Exchange(value = "leyou.sms.exchange", ignoreDeclarationExceptions = "true"),
            key = {"verifycode.sms"}))
    public void sendSms(Map<String, String> msg) throws ClientException {

        if(CollectionUtils.isEmpty(msg)){
            return ;
        }
        String phone = msg.get("phone");
        String code = msg.get("code");
        if(StringUtils.isNoneBlank(phone) && StringUtils.isNoneBlank(code)){
            this.smsUtils.sendSms(phone, code, this.smsProperties.getSignName(), this.smsProperties.getVerifyCodeTemplate());
        }
    }
