boot-简单队列

1.总配置文件

• pom文件

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

• application.properties

spring.application.name=spirng-boot-rabbitmq
spring.rabbitmq.host=127.0.0.1
spring.rabbitmq.port=5672
spring.rabbitmq.username=admin
spring.rabbitmq.password=admin

• 配置队列

package com.zpc.rabbitmq;
import org.springframework.amqp.core.Queue;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
public class RabbitConfig {
    @Bean
    public Queue queue() {
        return new Queue("q_hello");
    }
}

2.撸代码

• 生产者

package com.zpc.rabbitmq;

import org.springframework.amqp.core.AmqpTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
import java.text.SimpleDateFormat;
import java.util.Date;

@Component
public class HelloSender {
    @Autowired
    private AmqpTemplate rabbitTemplate;

    public void send() {
        String date = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss").format(new Date());//24小时制
        String context = "hello " + date;
        System.out.println("Sender : " + context);
        //简单对列的情况下routingKey即为Q名
        this.rabbitTemplate.convertAndSend("q_hello", context);
    }
}

• 接收者

package com.zpc.rabbitmq;

import org.springframework.amqp.rabbit.annotation.RabbitHandler;
import org.springframework.amqp.rabbit.annotation.RabbitListener;
import org.springframework.stereotype.Component;

@Component
@RabbitListener(queues = "q_hello")
public class HelloReceiver {

    @RabbitHandler
    public void process(String hello) {
        System.out.println("Receiver  : " + hello);
    }
}

• 测试

package com.zpc.rabbitmq;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;

@RunWith(SpringRunner.class)
@SpringBootTest
public class RabbitMqHelloTest {

    @Autowired
    private HelloSender helloSender;

    @Test
    public void hello() throws Exception {
        helloSender.send();
    }
}
