中间件——（五）RabbitMQ整合SpringBoot

RabbitMQ整合SpringBoot

【一】前言

经过了前几节枯燥的学习，现在进入真正实际项目中使用的方法，实际的项目开发中，RabbitMQ和SpringBoot进行整合是很常见的，也是实际项目中使用得最多的地方，下面我们一起来学习吧。

【二】创建生产者

• 1、创建Spirngboot项目

• 2、添加maven依赖

这里是整合生产者的maven配置

<?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">
	<modelVersion>4.0.0</modelVersion>

	<groupId>com.bfxy</groupId>
	<artifactId>rabbitmq-springboot-producer</artifactId>
	<version>0.0.1-SNAPSHOT</version>
	<packaging>jar</packaging>

	<name>rabbitmq-springboot-producer</name>
	<description>rabbitmq-springboot-producer</description>

	<parent>
		<groupId>org.springframework.boot</groupId>
		<artifactId>spring-boot-starter-parent</artifactId>
		<version>2.0.2.RELEASE</version>
		<relativePath/> <!-- lookup parent from repository -->
	</parent>

	<properties>
		<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
		<project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
		<java.version>1.8</java.version>
	</properties>

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

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

	<build>
		<plugins>
			<plugin>
				<groupId>org.springframework.boot</groupId>
				<artifactId>spring-boot-maven-plugin</artifactId>
			</plugin>
		</plugins>
	</build>


</project>

• 3、配置yml文件

spring.rabbitmq.addresses=192.168.179.130:5672
spring.rabbitmq.username=guest
spring.rabbitmq.password=guest
spring.rabbitmq.virtual-host=/
#连接时间
spring.rabbitmq.connection-timeout=15000

#消息的确认模式
spring.rabbitmq.publisher-confirms=true
#消息返回模式
spring.rabbitmq.publisher-returns=true
spring.rabbitmq.template.mandatory=true

• 4、对生产者进行封装

定义order对象，这地方Order必须进行序列化，才能进行对象的传输

public class Order implements Serializable {

	private String id;
	private String name;
	
	public Order() {
	}
	public Order(String id, String name) {
		super();
		this.id = id;
		this.name = name;
	}
	public String getId() {
		return id;
	}
	public void setId(String id) {
		this.id = id;
	}
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
}

对生产者进行封装，并且包含了对消息确认的监听和消息返回的处理

@Component
public class RabbitSender {

	//自动注入RabbitTemplate模板类
	@Autowired
	private RabbitTemplate rabbitTemplate;  
	
	//回调函数: confirm确认
	final ConfirmCallback confirmCallback = new RabbitTemplate.ConfirmCallback() {
		@Override
		public void confirm(CorrelationData correlationData, boolean ack, String cause) {
			System.err.println("correlationData: " + correlationData);
			System.err.println("ack: " + ack);
			if(!ack){
				System.err.println("异常处理....");
			}
		}
	};
	
	//回调函数: return返回
	final ReturnCallback returnCallback = new RabbitTemplate.ReturnCallback() {
		@Override
		public void returnedMessage(org.springframework.amqp.core.Message message, int replyCode, String replyText,
				String exchange, String routingKey) {
			System.err.println("return exchange: " + exchange + ", routingKey: " 
				+ routingKey + ", replyCode: " + replyCode + ", replyText: " + replyText);
		}
	};
	
	//发送消息方法调用: 构建Message消息
	public void send(Object message, Map<String, Object> properties) throws Exception {
		MessageHeaders mhs = new MessageHeaders(properties);
		Message msg = MessageBuilder.createMessage(message, mhs);
		rabbitTemplate.setConfirmCallback(confirmCallback);
		rabbitTemplate.setReturnCallback(returnCallback);
		//id + 时间戳 全局唯一 
		CorrelationData correlationData = new CorrelationData("1234567890");
		rabbitTemplate.convertAndSend("exchange-1", "springboot.abc", msg, correlationData);
	}
	
	//发送消息方法调用: 构建自定义对象消息
	public void sendOrder(Order order) throws Exception {
		rabbitTemplate.setConfirmCallback(confirmCallback);
		rabbitTemplate.setReturnCallback(returnCallback);
		//id + 时间戳 全局唯一 
		CorrelationData correlationData = new CorrelationData("0987654321");
		rabbitTemplate.convertAndSend("exchange-2", "springboot.def", order, correlationData);
	}
	
}

• 5、发送消息

@RunWith(SpringRunner.class)
@SpringBootTest
public class ApplicationTests {
	
	@Autowired
	private RabbitSender rabbitSender;

	private static SimpleDateFormat simpleDateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss.SSS");
	
	@Test
	public void testSender1() throws Exception {
		 Map<String, Object> properties = new HashMap<>();
		 properties.put("number", "12345");
		 properties.put("send_time", simpleDateFormat.format(new Date()));
		 rabbitSender.send("Hello RabbitMQ For Spring Boot!", properties);
	}
	
	@Test
	public void testSender2() throws Exception {
		 Order order = new Order("001", "第一个订单");
		 rabbitSender.sendOrder(order);
	}
	
}

【三】创建消费者

• 1、创建Spirngboot项目

消费者构建成功以后，会生成以下的目录结构：

• 2、添加maven依赖

下面试所有的消费者端的maven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">
	<modelVersion>4.0.0</modelVersion>

	<groupId>com.bfxy</groupId>
	<artifactId>rabbitmq-springboot-consumer</artifactId>
	<version>0.0.1-SNAPSHOT</version>
	<packaging>jar</packaging>

	<name>rabbitmq-springboot-consumer</name>
	<description>rabbitmq-springboot-consumer</description>

	<parent>
		<groupId>org.springframework.boot</groupId>
		<artifactId>spring-boot-starter-parent</artifactId>
		<version>2.0.2.RELEASE</version>
		<relativePath/> <!-- lookup parent from repository -->
	</parent>

	<properties>
		<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
		<project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
		<java.version>1.8</java.version>
	</properties>

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

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

	<build>
		<plugins>
			<plugin>
				<groupId>org.springframework.boot</groupId>
				<artifactId>spring-boot-maven-plugin</artifactId>
			</plugin>
		</plugins>
	</build>
</project>

• 3、配置yml文件

spring.rabbitmq.addresses=192.168.179.130:5672
spring.rabbitmq.username=guest
spring.rabbitmq.password=guest
spring.rabbitmq.virtual-host=/
spring.rabbitmq.connection-timeout=15000

spring.rabbitmq.listener.simple.acknowledge-mode=manual
spring.rabbitmq.listener.simple.concurrency=5
spring.rabbitmq.listener.simple.max-concurrency=10

#申明队列，交换机，路由key
spring.rabbitmq.listener.order.queue.name=queue-2
spring.rabbitmq.listener.order.queue.durable=true
spring.rabbitmq.listener.order.exchange.name=exchange-2
spring.rabbitmq.listener.order.exchange.durable=true
spring.rabbitmq.listener.order.exchange.type=topic
spring.rabbitmq.listener.order.exchange.ignoreDeclarationExceptions=true
spring.rabbitmq.listener.order.key=springboot.*

• 4、RabbitListener进行消费

@Component
public class RabbitReceiver {


	/**
	 * 这个地方进行申明的队列，交换机会自动创建。
	 * 但是队列，交换机名称已经写死
	 * @param message
	 * @param channel
	 * @throws Exception
	 */
	@RabbitListener(bindings = @QueueBinding(
			value = @Queue(value = "queue-1", durable="true"),
			exchange = @Exchange(value = "exchange-1", durable="true", type= "topic", ignoreDeclarationExceptions = "true"),
			key = "springboot.*"
			)
	)
	@RabbitHandler
	public void onMessage(Message message, Channel channel) throws Exception {
		System.err.println("--------------------------------------");
		System.err.println("消费端Payload: " + message.getPayload());
		Long deliveryTag = (Long)message.getHeaders().get(AmqpHeaders.DELIVERY_TAG);
		//手工ACK
		channel.basicAck(deliveryTag, false);
	}
	
	
	/**
	 * 从配置文件中获取所需要的配置
	 * @param order
	 * @param channel
	 * @param headers
	 * @throws Exception
	 */
	@RabbitListener(bindings = @QueueBinding(
			value = @Queue(value = "${spring.rabbitmq.listener.order.queue.name}", 
			durable="${spring.rabbitmq.listener.order.queue.durable}"),
			
			exchange = @Exchange(value = "${spring.rabbitmq.listener.order.exchange.name}", 
			durable="${spring.rabbitmq.listener.order.exchange.durable}", 
			type= "${spring.rabbitmq.listener.order.exchange.type}", 
			ignoreDeclarationExceptions = "${spring.rabbitmq.listener.order.exchange.ignoreDeclarationExceptions}"),
			
			key = "${spring.rabbitmq.listener.order.key}"
			)
	)
	@RabbitHandler
	public void onOrderMessage(@Payload com.bfxy.springboot.entity.Order order, 
			Channel channel, 
			@Headers Map<String, Object> headers) throws Exception {
		System.err.println("--------------------------------------");
		System.err.println("消费端order: " + order.getId());
		Long deliveryTag = (Long)headers.get(AmqpHeaders.DELIVERY_TAG);
		//手工ACK
		channel.basicAck(deliveryTag, false);
	}
	
	
}
