1 producers
Step 1: reference the relevant jar package.
<dependency> <groupId>org.springframework</groupId> <artifactId>spring-jms</artifactId> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context-support</artifactId> </dependency> <!-- Message queue --> <dependency> <groupId>org.apache.activemq</groupId> <artifactId>activemq-all</artifactId> </dependency>
Step 2: configure Activemq to integrate spring. Configure connectionfactory applicationcontext-Activemq.xml
Step 3: configure producers.
Use the JMSTemplate object. Send a message.
Step 4: configure the Destination in the spring container.

Step 5: code test

2 consumers
2.2.2. Receiving message
Receive message in E3 search service.
Step 1: add the jar package related to Activemq to the project
Step 2: create an implementation class of MessageListener.
package com.shi.search.activemq; import javax.jms.JMSException; import javax.jms.Message; import javax.jms.MessageListener; import javax.jms.TextMessage; /** * * @author: SHF * @date: 2018 2:33:05 PM, March 16, 2016 * @Description: Message queuing listener, consumer. Used to receive messages */ public class MyMessageListener implements MessageListener { @Override public void onMessage(Message paramMessage) { // Processing received messages in listening TextMessage textMessage=(TextMessage) paramMessage; try { String text = textMessage.getText(); System.out.println(text); } catch (JMSException e) { e.printStackTrace(); } } }
Step 3: configure spring and Activemq integration.

Step 4: test the code.
