2、rabbitmq链接配置
spring:
rabbitmq:
host: 127.0.0.1
port: 5672
username: wq
password: qifeng
virtual-host: /
#开启ack
listener:
direct:
acknowledge-mode: manual
prefetch: 1 # 限制一次拉取消息的数量
simple:
acknowledge-mode: manual #采取手动应答
#concurrency: 1 # 指定最小的消费者数量
#max-concurrency: 1 #指定最大的消费者数量
retry:
enabled: true # 是否支持重试
3、生产者
声明交换机、队列、绑定关于
package com.wanqi.mq;
import org.springframework.amqp.core.*;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
* @Description TODO
* @Version 1.0.0
* @Date 2022/11/19
* @Author wandaren
@Configuration
public class RabbitMQConfig {
public static final String EXCHANGE_NAME = "boot_topic_exchange";
public static final String QUEUE_NAME = "boot_queue";
//交换机
@Bean("bootExchange")
public Exchange bootExchange(){
return ExchangeBuilder.topicExchange(EXCHANGE_NAME).durable(true)
.build();
@Bean("bootQueue")
public Queue bootQueue(){
return QueueBuilder.durable(QUEUE_NAME).build();
//队列和交换机绑定关系
知道哪个队列
知道哪个交换机
知道routing key
@Bean
public Binding bindingQueueExchange(@Qualifier("bootQueue") Queue queue,
@Qualifier("bootExchange") Exchange exchange){
return BindingBuilder.bind(queue).to(exchange).with("boot.#").noargs();
package com.wanqi;
import com.wanqi.mq.RabbitMQConfig;
import org.junit.jupiter.api.Test;
import org.springframework.amqp.rabbit.core.RabbitTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
@SpringBootTest
class SpringbootMqProducersApplicationTests {
@Autowired
private RabbitTemplate rabbitTemplate;
@Test
void contextLoads() {
rabbitTemplate.convertAndSend(RabbitMQConfig.EXCHANGE_NAME, "boot.test", "boot mq hello~~~");
4、消费者
package com.wanqi.listener;
import com.rabbitmq.client.Channel;
import org.springframework.amqp.core.Message;
import org.springframework.amqp.rabbit.annotation.RabbitListener;
import org.springframework.stereotype.Component;
import java.io.IOException;
* @Description TODO
* @Version 1.0.0
* @Date 2022/11/19
* @Author wandaren
@Component
public class RabbitMQListener {
@RabbitListener(queues = {"boot_queue"})
public void listenerQueue(Object msg, Message message, Channel channel) {
final long deliveryTag = message.getMessageProperties().getDeliveryTag();
try {
System.out.println(msg.toString());
System.out.println(new String(message.getBody()));
// int x = 3/0;
channel.basicAck(deliveryTag, true);
} catch (Exception e) {
try {
channel.basicNack(deliveryTag, true, true);
} catch (IOException ex) {
throw new RuntimeException(ex);
5、死信队列
消息成为死信的三种情况
1、队列消息长度到达限制；
2、消费者拒接消费消息，并且不重回队列；
3、原队列存在消息过期设置，消息到达超时时间未被消费；
5.1、声明交换机、队列、绑定队列
topic模式
package com.wanqi.mq;
import org.springframework.amqp.core.*;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
* @Description TODO
* @Version 1.0.0
* @Date 2022/11/19
* @Author wandaren
@Configuration
public class QDRabbitMQConfig {
//交换机名称
public static final String ITEM_EXCHANGE = "item_exchange";
public static final String DEAD_EXCHANGE = "dead_exchange";
//队列名称
public static final String ITEM_QUEUE = "item_queue";
public static final String DEAD_QUEUE = "dead_queue";
//声明业务交换机
@Bean("itemExchange")
public Exchange itemExchange(){
return ExchangeBuilder.topicExchange(ITEM_EXCHANGE).durable(true).build();
//声明死信交换机
@Bean("deadExchange")
public Exchange deadExchange(){
return ExchangeBuilder.topicExchange(DEAD_EXCHANGE).durable(true).build();
* 声明普通队列，设置队列消息过期时间，队列长度，绑定的死信队列
@Bean("itemQueue")
public Queue itemQueue(){
return QueueBuilder
.durable(ITEM_QUEUE)
// 队列消息过期时间
.ttl(10000)
// 队列长度
.maxLength(15)
// 声明当前队列绑定的死信交换机
.deadLetterExchange(DEAD_EXCHANGE)
// 声明当前队列死信转发的路由key
.deadLetterRoutingKey("infoDead.haha")
.build();
* 死信队列，消费者需要监听的队列
@Bean("deadQueue")
public Queue deadQueue(){
return QueueBuilder
.durable(DEAD_QUEUE)
.build();
//绑定队列和交换机（业务）
@Bean
public Binding itemQueueExchange(@Qualifier("itemQueue") Queue queue,
@Qualifier("itemExchange") Exchange exchange){
return BindingBuilder.bind(queue).to(exchange).with("infoRouting.#").noargs();
//绑定队列和交换机（死信）
@Bean
public Binding deadQueueExchange(@Qualifier("deadQueue") Queue queue,
@Qualifier("deadExchange") Exchange exchange){
return BindingBuilder.bind(queue).to(exchange).with("infoDead.#").noargs();
5.2、发送测试消息
package com.wanqi;
import com.wanqi.mq.RabbitMQConfig;
import com.wanqi.mq.RabbitMQConfig2;
import org.junit.jupiter.api.Test;
import org.springframework.amqp.core.Message;
import org.springframework.amqp.core.MessageProperties;
import org.springframework.amqp.rabbit.core.RabbitTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
@SpringBootTest
class SpringbootMqProducersApplicationTests {
@Autowired
private RabbitTemplate rabbitTemplate;
// 原队列存在消息过期设置，消息到达超时时间未被消费；
@Test
void contextLoads3() {
MessageProperties messageProperties = new MessageProperties();
// 设置过期时间，单位：毫秒
messageProperties.setExpiration("5000");
byte[] msgBytes = "rabbitmq ttl message ...".getBytes();
Message message = new Message(msgBytes, messageProperties);
//发送消息
rabbitTemplate.convertAndSend(QDRabbitMQConfig.ITEM_EXCHANGE,"infoRouting.hehe",message);
System.out.println("发送消息成功");
// 模拟队列消息长度到达限制
@Test
void contextLoads4() {
for (int i = 0; i i++) {
rabbitTemplate.convertAndSend(QDRabbitMQConfig.ITEM_EXCHANGE,"infoRouting.hehe",i + "---message");
5.3、消费者
package com.wanqi.listener;
import com.rabbitmq.client.Channel;
import org.springframework.amqp.core.Message;
import org.springframework.amqp.rabbit.annotation.RabbitListener;
import org.springframework.stereotype.Component;
import java.io.IOException;
* @Description TODO
* @Version 1.0.0
* @Date 2022/11/19
* @Author wandaren
@Component
public class RabbitMQListener {
@RabbitListener(queues = {"dead_queue"})
public void listenerQueue2(Object msg, Message message, Channel channel) {
final long deliveryTag = message.getMessageProperties().getDeliveryTag();
try {
System.out.println(msg.toString());
channel.basicAck(deliveryTag, true);
} catch (Exception e) {
try {
channel.basicNack(deliveryTag, true, true);
} catch (IOException ex) {
throw new RuntimeException(ex);
6、延迟队列（TTL + 死信队列）
6.1、声明交换机、队列、绑定队列
direct模式
package com.wanqi.mq;
import org.springframework.amqp.core.*;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
* @Description TODO
* @Version 1.0.0
* @Date 2022/11/19
* @Author wandaren
@Configuration
public class TtlQueueConfig {
//普通交换机名称
public static final String X_CHANGE = "X_Exchange";
//死信交换机名称
public static final String Y_DEAD_CHANGE = "Y_Exchange";
//普通队列
public static final String QUEUE_A = "QA_QUEUE";
public static final String QUEUE_B = "QB_QUEUE";
//死信队列
public static final String DEAD_QUEUE_D = "QD_QUEUE";
//声明普通交换机
@Bean("xExchange")
public DirectExchange xExchange() {
return ExchangeBuilder.directExchange(X_CHANGE).durable(true)
.build();
//声明死信交换机
@Bean("yExchange")
public DirectExchange yExchange() {
return ExchangeBuilder.directExchange(Y_DEAD_CHANGE).durable(true)
.build();
* 声明队列,延迟10秒
@Bean("queueA")
public Queue queueA() {
return QueueBuilder.durable(QUEUE_A)
.deadLetterExchange(Y_DEAD_CHANGE) //死信交换机
.deadLetterRoutingKey("YD") //死信RoutingKey
.ttl(10000) //消息过期时间
.build();
* 声明队列，延迟40秒
* @return
@Bean("queueB")
public Queue queueB() {
return QueueBuilder.durable(QUEUE_B)
.deadLetterExchange(Y_DEAD_CHANGE) //死信交换机
.deadLetterRoutingKey("YD") //死信RoutingKey
.ttl(40000) //消息过期时间
.build();
@Bean
public Binding queueABindingX(@Qualifier("queueA") Queue queueA, @Qualifier("xExchange") DirectExchange xExchange) {
return BindingBuilder.bind(queueA).to(xExchange).with("XA");
//绑定 X_CHANGE绑定queueB
@Bean
public Binding queueBBindingX(@Qualifier("queueB") Queue queueB, @Qualifier("xExchange") DirectExchange xExchange) {
return BindingBuilder.bind(queueB).to(xExchange).with("XB");
@Bean
public Binding queueDBindingY(@Qualifier("queueD") Queue queueD, @Qualifier("yExchange") DirectExchange yExchange) {
return BindingBuilder.bind(queueD).to(yExchange).with("YD");
6.2、发送消息
@Test
void contextLoads5() {
String message = "延迟队列消息";
rabbitTemplate.convertAndSend(TtlQueueConfig.X_CHANGE, "XA", "TTL=10s的队列：" + message);
rabbitTemplate.convertAndSend(TtlQueueConfig.X_CHANGE, "XB", "TTL=40s的队列：" + message);
6.3、消费
package com.wanqi.listener;
import com.rabbitmq.client.Channel;
import org.springframework.amqp.core.Message;
import org.springframework.amqp.rabbit.annotation.RabbitListener;
import org.springframework.stereotype.Component;
import java.io.IOException;
import java.util.Date;
* @Description TODO
* @Version 1.0.0
* @Date 2022/11/19
* @Author wandaren
@Component
public class RabbitMQListener {
@RabbitListener(queues = "QD_QUEUE")
public void receiveMessage(Object msg,Message message, Channel channel){
final long deliveryTag = message.getMessageProperties().getDeliveryTag();
try {
System.out.println(msg.toString());
System.out.print("当前时间: " + new Date());
System.out.println(" 收到死信队列的消息：" + msg);
channel.basicAck(deliveryTag, true);
} catch (Exception e) {
try {
channel.basicNack(deliveryTag, true, true);
} catch (IOException ex) {
throw new RuntimeException(ex);
