RabbitMQ學習筆記（5）----RabbitMQ整合Spring
阿新 • • 發佈：2018-11-19
在Spring AMQP專案中Spring也提供了對RabbitMQ的支援，這裡在之前學習SpringBoot的時候也整合過，但是今天這裡使用的Spring的xml配置來整個rabbit.
Spring AMQP專案地址：https://spring.io/projects/spring-amqp；
下面來看看使用方式。
1. 引入依賴
pom檔案如下：

2. 配置基礎資訊
rabbitMQ.xml
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:rabbit="http://www.springframework.org/schema/rabbit" xsi:schemaLocation="http://www.springframework.org/schema/rabbit http://www.springframework.org/schema/rabbit/spring-rabbit.xsd http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd"> <!--配置connection--> <rabbit:connection-factory id="connectionFactory" host="127.0.0.1" port="5672" username="wangx" password="wangx" virtual-host="/wangx"/> <!--使用admin管理factory--> <rabbit:admin connection-factory="connectionFactory"/> <!--定義模板，並指定交換機或queue--> <rabbit:template id="rabbitTemplate" connection-factory="connectionFactory" exchange="spring-exchange"/> <!--定義消費者所對應的key--> <rabbit:queue name="spring-queue" auto-declare="true"/> <!--宣告fanout的交換機--> <rabbit:fanout-exchange name="spring-exchange" auto-declare="true"> <rabbit:bindings> <rabbit:binding queue="spring-queue"/> </rabbit:bindings> </rabbit:fanout-exchange> <!--宣告監聽容器--> <rabbit:listener-container connection-factory="connectionFactory"> <!--指定監聽器所對應的bean和方法--> <rabbit:listener ref="consumer" method="listen" queue-names="spring-queue"/> </rabbit:listener-container> <!--消費者監聽方法--> <bean id="consumer" class="com.wangx.rabbitmq.spring.Consumer"/> </beans>
消費者：
Consumer
package com.wangx.rabbitmq.spring; public class Consumer { //對應監聽器中所指定的method public void listen(String msg) { System.out.println("Spring Consumer 接收到訊息：" + msg); } }
傳送訊息：
package com.wangx.rabbitmq.spring; import org.springframework.amqp.core.Message; import org.springframework.amqp.core.MessageProperties; import org.springframework.amqp.rabbit.core.RabbitTemplate; import org.springframework.context.ApplicationContext; import org.springframework.context.support.ClassPathXmlApplicationContext; public class Producer { public static void main(String[] args) { //讀取配置檔案 ApplicationContext context = new ClassPathXmlApplicationContext("rabbitMQ.xml"); //獲取模板類 RabbitTemplate template = context.getBean(RabbitTemplate.class); String str = "Spring-message"; //構建MessageProperties物件 MessageProperties messageProperties = new MessageProperties(); //設定引數 messageProperties.setContentEncoding("UTF-8"); messageProperties.setContentType("text/plain"); //構建訊息物件 Message message = new Message(str.getBytes(), messageProperties); //使用模板傳送訊息 template.send(message); } }
注意：
messageProperties.setContentEncoding("UTF-8");
messageProperties.setContentType("text/plain");
這兩個引數必須要配置，否則會報如下異常：
