spring-boot集成RabbitMQ

 

RabbitMQ的安装不在此赘述，想了解的可以参考：Spring Boot中使用RabbitMQ

 

1、新建一个spring-boot工程，本示例命名为：spring-boot-rabbitmq-demo

 

2、在pom.xml中引入amqp

 

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

 

 

3、在application.properties中配置rabbitmq

 

spring.application.name=spring-boot-rabbitmq-demo

spring.rabbitmq.host=127.0.0.1
spring.rabbitmq.port=5672
spring.rabbitmq.username=guest
spring.rabbitmq.password=guest
spring.rabbitmq.listener.simple.concurrency=10

 

 

4、配置RabbitMQ的队列和消息转换器

 

package com.huatech.config;

import org.springframework.amqp.core.Queue;
import org.springframework.amqp.rabbit.config.SimpleRabbitListenerContainerFactory;
import org.springframework.amqp.rabbit.connection.ConnectionFactory;
import org.springframework.amqp.rabbit.core.RabbitTemplate;
import org.springframework.amqp.support.converter.Jackson2JsonMessageConverter;
import org.springframework.amqp.support.converter.MessageConverter;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
public class RabbitConfig {

    @Bean
    public Queue helloQueue() {
        return new Queue("user");
    }

    @Bean
    public MessageConverter messageConverter() {
    	return new Jackson2JsonMessageConverter();
    }
    
    @Bean
    public SimpleRabbitListenerContainerFactory containerFactory(SimpleRabbitListenerContainerFactory factory) {
    	factory.setMessageConverter(messageConverter());
    	return factory;
    }

    @Bean
    public RabbitTemplate rabbitTemplate(ConnectionFactory connectionFactory) {
    	RabbitTemplate template = new RabbitTemplate(connectionFactory);
    	template.setMessageConverter(messageConverter());
    	return template;
    }
    
    

}

 

 

5、消息生产者UserSender

package com.huatech.rabbit;

import java.util.Date;

import org.springframework.amqp.rabbit.core.RabbitTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;

import com.huatech.domain.User;

@Component
public class UserSender {

    @Autowired
    private RabbitTemplate rabbitTemplate;

    public void send() {
    	for (int i = 0; i < 100; i++) {
    		User user = new User();
    		user.setCreateTime(new Date());
    		user.setEmail("[e-mail]");
    		user.setId(11L);
    		user.setRemark("remark");
    		user.setUsername("lihua");        
    		System.out.println("Sender : " + user.toString());
    		this.rabbitTemplate.convertAndSend("user", user);			
		}
    }

}

 

 

6、消息消费者UserReceiver

package com.huatech.rabbit;

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

import com.huatech.domain.User;

@Component
@RabbitListener(queues = "user", containerFactory = "containerFactory")
public class UserReceiver {

    @RabbitHandler
    public void process(User user) {
        System.out.println("Receiver : " + user.toString());
    }
	

}

 

7、测试

package com.huatech;

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;

import com.huatech.rabbit.UserSender;

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

	@Autowired
	private UserSender sender;

	@Test
	public void testUser() throws Exception {
		sender.send();
		Thread.sleep(5000);
	}

}
