這篇文章主要介紹了springboot2.5.6集成RabbitMq實現(xiàn)Topic主題模式(推薦),pom.xml引入依賴和常量類創(chuàng)建,本文通過實例代碼給大家介紹的非常詳細,需要的朋友參考下吧
1.application.yml
server:
port: 8184
spring:
application:
name: rabbitmq-demo
rabbitmq:
host: 127.0.0.1 # ip地址
port: 5672

2.pom.xml引入依賴
<!-- rabbitmq -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-amqp</artifactId>
</dependency>
3.常量類創(chuàng)建
/**
* @author kkp
* @ClassName RabbitMqConstants
* @date 2021/11/3 14:16
* @Description
*/
public class RabbitMqConstants {
public final static String TEST1_QUEUE = "test1-queue";
public final static String TEST2_QUEUE = "test2-queue";
public final static String EXCHANGE_NAME = "test.topic.exchange";
/**
* routingKey1
*/
public final static String TOPIC_TEST1_ROUTINGKEY = "topic.test1.*";
public final static String TOPIC_TEST1_ROUTINGKEY_TEST = "topic.test1.test";
/**
* routingKey1
*/
public final static String TOPIC_TEST2_ROUTINGKEY = "topic.test2.*";
public final static String TOPIC_TEST2_ROUTINGKEY_TEST = "topic.test2.test";
}
4.配置Configuration
import com.example.demo.common.RabbitMqConstants;
import lombok.extern.slf4j.Slf4j;
import org.springframework.amqp.core.*;
import org.springframework.amqp.rabbit.connection.CachingConnectionFactory;
import org.springframework.amqp.rabbit.core.RabbitTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.beans.factory.config.ConfigurableBeanFactory;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Scope;
/**
* @author kkp
* @ClassName RabbitMqConfig
* @date 2021/11/3 14:16
* @Description
*/
@Slf4j
@Configuration
public class RabbitMqConfig {
@Autowired
private CachingConnectionFactory connectionFactory;
/**
* 聲明交換機
*/
@Bean(RabbitMqConstants.EXCHANGE_NAME)
public Exchange exchange(){
//durable(true) 持久化,mq重啟之后交換機還在
// Topic模式
//return ExchangeBuilder.topicExchange(RabbitMqConstants.EXCHANGE_NAME).durable(true).build();
//發(fā)布訂閱模式
return ExchangeBuilder.fanoutExchange(RabbitMqConstants.EXCHANGE_NAME).durable(true).build();
}
/**
* 聲明隊列
* new Queue(QUEUE_EMAIL,true,false,false)
* durable="true" 持久化 rabbitmq重啟的時候不需要創(chuàng)建新的隊列
* auto-delete 表示消息隊列沒有在使用時將被自動刪除 默認是false
* exclusive 表示該消息隊列是否只在當前connection生效,默認是false
*/
@Bean(RabbitMqConstants.TEST1_QUEUE)
public Queue esQueue() {
return new Queue(RabbitMqConstants.TEST1_QUEUE);
}
/**
* 聲明隊列
*/
@Bean(RabbitMqConstants.TEST2_QUEUE)
public Queue gitalkQueue() {
return new Queue(RabbitMqConstants.TEST2_QUEUE);
}
/**
* TEST1_QUEUE隊列綁定交換機,指定routingKey
*/
@Bean
public Binding bindingEs(@Qualifier(RabbitMqConstants.TEST1_QUEUE) Queue queue,
@Qualifier(RabbitMqConstants.EXCHANGE_NAME) Exchange exchange) {
return BindingBuilder.bind(queue).to(exchange).with(RabbitMqConstants.TOPIC_TEST1_ROUTINGKEY).noargs();
}
/**
* TEST2_QUEUE隊列綁定交換機,指定routingKey
*/
@Bean
public Binding bindingGitalk(@Qualifier(RabbitMqConstants.TEST2_QUEUE) Queue queue,
@Qualifier(RabbitMqConstants.EXCHANGE_NAME) Exchange exchange) {
return BindingBuilder.bind(queue).to(exchange).with(RabbitMqConstants.TOPIC_TEST2_ROUTINGKEY).noargs();
}
/**
* 如果需要在生產(chǎn)者需要消息發(fā)送后的回調(diào),
* 需要對rabbitTemplate設置ConfirmCallback對象,
* 由于不同的生產(chǎn)者需要對應不同的ConfirmCallback,
* 如果rabbitTemplate設置為單例bean,
* 則所有的rabbitTemplate實際的ConfirmCallback為最后一次申明的ConfirmCallback。
* @return
*/
@Bean
@Scope(ConfigurableBeanFactory.SCOPE_PROTOTYPE)
public RabbitTemplate rabbitTemplate() {
RabbitTemplate template = new RabbitTemplate(connectionFactory);
return template;
}
}
5.Rabbit工具類創(chuàng)建
import lombok.extern.slf4j.Slf4j;
import org.springframework.amqp.core.Message;
import org.springframework.amqp.rabbit.connection.CorrelationData;
import org.springframework.amqp.rabbit.core.RabbitTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
import java.util.UUID;
/**
* @author kkp
* @ClassName RabbitMqUtils
* @date 2021/11/3 14:21
* @Description
*/
@Slf4j
@Component
public class RabbitMqUtils implements RabbitTemplate.ConfirmCallback, RabbitTemplate.ReturnCallback{
private RabbitTemplate rabbitTemplate;
/**
* 構造方法注入
*/
@Autowired
public RabbitMqUtils(RabbitTemplate rabbitTemplate) {
this.rabbitTemplate = rabbitTemplate;
//這是是設置回調(diào)能收到發(fā)送到響應
rabbitTemplate.setConfirmCallback(this);
//如果設置備份隊列則不起作用
rabbitTemplate.setMandatory(true);
rabbitTemplate.setReturnCallback(this);
}
/**
* 回調(diào)確認
*/
@Override
public void confirm(CorrelationData correlationData, boolean ack, String cause) {
if(ack){
log.info("消息發(fā)送成功:correlationData({}),ack({}),cause({})",correlationData,ack,cause);
}else{
log.info("消息發(fā)送失?。篶orrelationData({}),ack({}),cause({})",correlationData,ack,cause);
}
}
/**
* 消息發(fā)送到轉換器的時候沒有對列,配置了備份對列該回調(diào)則不生效
* @param message
* @param replyCode
* @param replyText
* @param exchange
* @param routingKey
*/
@Override
public void returnedMessage(Message message, int replyCode, String replyText, String exchange, String routingKey) {
log.info("消息丟失:exchange({}),route({}),replyCode({}),replyText({}),message:{}",exchange,routingKey,replyCode,replyText,message);
}
/**
* 發(fā)送到指定Queue
* @param queueName
* @param obj
*/
public void send(String queueName, Object obj){
CorrelationData correlationId = new CorrelationData(UUID.randomUUID().toString());
this.rabbitTemplate.convertAndSend(queueName, obj, correlationId);
}
/**
* 1、交換機名稱
* 2、routingKey
* 3、消息內(nèi)容
*/
public void sendByRoutingKey(String exChange, String routingKey, Object obj){
CorrelationData correlationId = new CorrelationData(UUID.randomUUID().toString());
this.rabbitTemplate.convertAndSend(exChange, routingKey, obj, correlationId);
}
}
6.service創(chuàng)建
public interface TestService {
String sendTest1(String content);
String sendTest2(String content);
}
7.impl實現(xiàn)
import com.example.demo.common.RabbitMqConstants;
import com.example.demo.util.RabbitMqUtils;
import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
/**
* @author kkp
* @ClassName TestServiceImpl
* @date 2021/11/3 14:24
* @Description
*/
@Service
@Slf4j
public class TestServiceImpl implements TestService {
@Autowired
private RabbitMqUtils rabbitMqUtils;
@Override
public String sendTest1(String content) {
rabbitMqUtils.sendByRoutingKey(RabbitMqConstants.EXCHANGE_NAME,
RabbitMqConstants.TOPIC_TEST1_ROUTINGKEY_TEST, content);
log.info(RabbitMqConstants.TOPIC_TEST1_ROUTINGKEY_TEST+"***************發(fā)送成功*****************");
return "發(fā)送成功!";
}
@Override
public String sendTest2(String content) {
rabbitMqUtils.sendByRoutingKey(RabbitMqConstants.EXCHANGE_NAME,
RabbitMqConstants.TOPIC_TEST2_ROUTINGKEY_TEST, content);
log.info(RabbitMqConstants.TOPIC_TEST2_ROUTINGKEY_TEST+"***************發(fā)送成功*****************");
return "發(fā)送成功!";
}
}
8.監(jiān)聽類
import com.example.demo.common.RabbitMqConstants;
import lombok.extern.slf4j.Slf4j;
import org.springframework.amqp.core.ExchangeTypes;
import org.springframework.amqp.core.Message;
import org.springframework.amqp.rabbit.annotation.Exchange;
import org.springframework.amqp.rabbit.annotation.Queue;
import org.springframework.amqp.rabbit.annotation.QueueBinding;
import org.springframework.amqp.rabbit.annotation.RabbitListener;
import org.springframework.stereotype.Component;
import com.rabbitmq.client.Channel;
/**
* @author kkp
* @ClassName RabbitMqListener
* @date 2021/11/3 14:22
* @Description
*/
@Slf4j
@Component
public class RabbitMqListener {
@RabbitListener(queues = RabbitMqConstants.TEST1_QUEUE)
public void test1Consumer(Message message, Channel channel) {
try {
//手動確認消息已經(jīng)被消費
channel.basicAck(message.getMessageProperties().getDeliveryTag(), false);
log.info("Counsoum1消費消息:" + message.toString() + "。成功!");
} catch (Exception e) {
e.printStackTrace();
log.info("Counsoum1消費消息:" + message.toString() + "。失?。?);
}
}
@RabbitListener(queues = RabbitMqConstants.TEST2_QUEUE)
public void test2Consumer(Message message, Channel channel) {
try {
//手動確認消息已經(jīng)被消費
channel.basicAck(message.getMessageProperties().getDeliveryTag(), false);
log.info("Counsoum2消費消息:" + message.toString() + "。成功!");
} catch (Exception e) {
e.printStackTrace();
log.info("Counsoum2消費消息:" + message.toString() + "。失??!");
}
}
}
9.Controller測試
import com.example.demo.server.TestService;
import jdk.nashorn.internal.objects.annotations.Getter;
import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.*;
import java.util.Map;
/**
* @author kkp
* @ClassName TestController
* @date 2021/11/3 14:25
* @Description
*/
@Slf4j
@RestController
@RequestMapping("/enterprise")
public class TestController {
@Autowired
private TestService testService;
@GetMapping("/finance")
public String hello3(@RequestParam(required = false) Map<String, Object> params) {
return testService.sendTest2(params.get("entId").toString());
}
/**
* 發(fā)送消息test2
* @param content
* @return
*/
@PostMapping(value = "/finance2")
public String sendTest2(@RequestBody String content) {
return testService.sendTest2(content);
}
}
