使用RabbitMQ发送短信

1、在项目中分别创建模块financial-core、financial-mq、financial-sms，如图：

模块构成

  <modules>
        <module>financial-common</module>
        <module>financial-base</module>
        <module>financial-core</module>
        <module>financial-gateway</module>       
        <module>financial-sms</module>
        <module>financial-mq</module>        
    </modules>

2、搭建RabbitMQ服务，参考下面文章

3、MQ模块financial-mq

3.1 在pom.xml添加依赖

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <parent>
        <artifactId>koo-financial-parent</artifactId>
        <groupId>com.koo</groupId>
        <version>1.0.0</version>
    </parent>
    <modelVersion>4.0.0</modelVersion>

    <artifactId>financial-mq</artifactId>

    <properties>
        <maven.compiler.source>8</maven.compiler.source>
        <maven.compiler.target>8</maven.compiler.target>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    </properties>

    <dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-amqp</artifactId>
        </dependency>

        <dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>fastjson</artifactId>
        </dependency>

        <dependency>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok</artifactId>
        </dependency>
    </dependencies>

</project>

3.2 MQ Json字符串转换 配置

@Configuration
public class MQConfig {
    @Bean
    public MessageConverter messageConverter(){
        //json字符串转换器
        return new Jackson2JsonMessageConverter();
    }
}

3.3 定义交换机、路由、队列常量

public class MQConst {

    public static final String EXCHANGE_TOPIC_SMS = "exchange.topic.sms";//交换机
    public static final String ROUTING_SMS_ITEM = "routing.sms.item";//路由
    public static final String QUEUE_SMS_ITEM = "queue.sms.item";//消息队列

}

3.4 定义发送方法

@Service
@Slf4j
public class MQService {

    @Resource
    private AmqpTemplate amqpTemplate;

    public boolean sendMessage(String exchange, String routingKey, Object message) {
        log.info("发送消息。。。。。。");
        amqpTemplate.convertAndSend(exchange, routingKey, message);
        return true;
    }
}

4、业务模块financial-core

4.1 在pom.xml中引入financial-mq模块

<dependencies>

        <dependency>
            <groupId>com.koo</groupId>
            <artifactId>financial-base</artifactId>
            <version>1.0.0</version>
        </dependency>

        <dependency>
            <groupId>com.koo</groupId>
            <artifactId>financial-mq</artifactId>
            <version>1.0.0</version>
        </dependency>     

    </dependencies>

4.2 在application.yml配置rabbitMQ信息

  #spring:
  rabbitmq:
    host: 127.0.0.1
    port: 5672
    virtual-host: /financial

4.3 发送信息

String mobile = userInfoService.getMobileByBindCode(bindCode);
SmsDTO smsDTO = new SmsDTO();
smsDTO.setMobile(mobile);
smsDTO.setMessage("充值成功");
mqService.sendMessage(
        MQConst.EXCHANGE_TOPIC_SMS,
        MQConst.ROUTING_SMS_ITEM,
        smsDTO
);

5、短信发送模块financial-sms

5.1 引入依赖

 <dependency>
            <groupId>com.koo</groupId>
            <artifactId>financial-mq</artifactId>
            <version>1.0.0</version>
        </dependency>

5.2 在application.yml配置rabbitMQ信息

  #spring:
  rabbitmq:
    host: 127.0.0.1
    port: 5672
    virtual-host: /financial

5.3 监听MQ消息，并发送短信

@Component
@Slf4j
public class SmsReceiver {

    @Resource
    private SmsService smsService;

    @RabbitListener(bindings = @QueueBinding(
            value = @Queue(value = MQConst.QUEUE_SMS_ITEM, durable = "true"),
            exchange = @Exchange(value = MQConst.EXCHANGE_TOPIC_SMS),
            key = {MQConst.ROUTING_SMS_ITEM}
    ))
    public void send(SmsDTO smsDTO) {
        log.info("SmsReceiver消息监听。。。。。。");
        HashMap<String, Object> param = new HashMap<>();
        param.put("code", smsDTO.getMessage());

        try {
            Thread.sleep(10000);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }

        smsService.send(smsDTO.getMobile(), SmsProperties.TEMPLATE_CODE, param);
    }
}
