- 队列消费者代码：
package com.huazai.activemq.spring.queue;
import org.apache.xbean.spring.context.ClassPathXmlApplicationContext;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.ApplicationContext;
import org.springframework.jms.core.JmsTemplate;
import org.springframework.stereotype.Service;
/**

*/
@Service
public class SpringMQConsumer {
@Autowired
private JmsTemplate jmsTemplate;
@Autowired
public void setJmsTemplate(JmsTemplate jmsTemplate) {
this.jmsTemplate = jmsTemplate;
}
public static void main(String[] args) {
ApplicationContext applicationContext = new ClassPathXmlApplicationContext("applicationContext.xml");
SpringMQConsumer springMQConsumer = applicationContext.getBean(SpringMQConsumer.class);
while(true) {
// 接受消息
String returnValue = (String) springMQConsumer.jmsTemplate.receiveAndConvert();
// 输入exit-退出
if ("exit-".equals(returnValue)) {
System.exit(-1);
}
System.out.println("****消费者收到的消息: " + returnValue);
}
}
}
队列生产者代码：
package com.huazai.activemq.spring.queue;
import org.apache.xbean.spring.context.ClassPathXmlApplicationContext;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.ApplicationContext;
import org.springframework.jms.core.JmsTemplate;
import org.springframework.stereotype.Service;
import java.util.Scanner;
/**

*/
@Service
public class SpringMQProducer {
static final Scanner input = new Scanner(System.in);
@Autowired
private final JmsTemplate jmsTemplate;
@Autowired
public SpringMQProducer(JmsTemplate jmsTemplate) {
this.jmsTemplate = jmsTemplate;
}
public static void main(String[] args) {
ApplicationContext applicationContext = new ClassPathXmlApplicationContext("applicationContext.xml");
SpringMQProducer springMQ_producer = applicationContext.getBean(SpringMQProducer.class);
JmsTemplate jmsTemplate = springMQ_producer.jmsTemplate;
// 发送消息
jmsTemplate.send(session -> session.createTextMessage("***Spring和ActiveMQ的整合case....."));
System.out.println("********send task over");
while(true) {
System.out.println("\n请输入要发送的内容");
final String msgText = input.next();
// 输入exit推出程序
if ("exit".equals(msgText)) {
System.exit(-1);
}
if (msgText.startsWith("auto:")) {
int amount;
try {
amount = Integer.parseInt(msgText.substring(5));
} catch (NumberFormatException e) {
System.out.println("auto指令格式错误，正确的应该是：auto:number");
continue;
}
System.out.println("请稍等...");
for (int i = 1; i <= amount; i++) {
final int ii = i;
jmsTemplate.send(session -> session.createTextMessage(ii + ""));
}
System.out.println(msgText + "\t->|\t指令执行完成");
} else {
jmsTemplate.send(session -> session.createTextMessage(msgText));
System.out.println(msgText + "\t->|\t发送完成");
}
}
}
}
- 启动消费者和订阅者，结果如下：
- 订阅者代码
package com.huazai.activemq.spring.topic;
import org.apache.xbean.spring.context.ClassPathXmlApplicationContext;
import org.springframework.context.ApplicationContext;
import org.springframework.jms.core.JmsTemplate;
import org.springframework.stereotype.Service;
import javax.jms.Destination;
/**
* @author DDKK.COM 弟弟快看，程序员编程资料站
* @date 2022/01/11 23:40
*/
@Service
public class SpringMQTopicConsumer {
private final JmsTemplate jmsTemplate;
public SpringMQTopicConsumer(JmsTemplate jmsTemplate) {
this.jmsTemplate = jmsTemplate;
}
public static void main(String[] args) {
ApplicationContext applicationContext = new ClassPathXmlApplicationContext("applicationContext.xml");
SpringMQTopicConsumer springMQConsumer = applicationContext.getBean(SpringMQTopicConsumer.class);
JmsTemplate jmsTemplate = springMQConsumer.jmsTemplate;
// applicationContext.xml的默认目的地配置为队列，所以此处需要用代码修改默认目的地
jmsTemplate.setDefaultDestination(((Destination) applicationContext.getBean("destinationTopic")));
// jmsTemplate.setDestinationResolver((session, s, b) -> session.createTopic("spring-test-topic"));
while (true) {
String returnValue = (String) jmsTemplate .receiveAndConvert();
if ("exit-".equals(returnValue)) {
System.exit( -1);
}
System.out.println("****消费者收到的消息: " + returnValue);
}
}
}
- 发布者代码
package com.huazai.activemq.spring.topic;
import org.apache.xbean.spring.context.ClassPathXmlApplicationContext;
import org.springframework.context.ApplicationContext;
import org.springframework.jms.core.JmsTemplate;
import org.springframework.stereotype.Service;
import javax.jms.Destination;
import java.util.Scanner;
/**
* @author DDKK.COM 弟弟快看，程序员编程资料站
* @date 2022/01/11 23:41
*/
@Service
public class SpringMQTopicProducer {
static final Scanner input = new Scanner(System.in);
private final JmsTemplate jmsTemplate;
public SpringMQTopicProducer(JmsTemplate jmsTemplate) {
this.jmsTemplate = jmsTemplate;
}
public static void main(String[] args) throws InterruptedException {
ApplicationContext applicationContext = new ClassPathXmlApplicationContext("applicationContext.xml");
SpringMQTopicProducer springMQ_topic_producer = applicationContext.getBean(SpringMQTopicProducer.class);
//直接调用application.xml里面创建的destinationTopic这个bean设置为目的地就行了
JmsTemplate jmsTemplate = springMQ_topic_producer.jmsTemplate;
// applicationContext.xml的默认目的地配置为队列，所以此处需要用代码修改默认目的地
jmsTemplate.setDefaultDestination(((Destination) applicationContext.getBean("destinationTopic")));
// jmsTemplate.setDestinationResolver((session, s, b) -> session.createTopic("spring-test-topic"));
jmsTemplate.send(session -> session.createTextMessage("***Spring和ActiveMQ的整合TopicCase111....."));
System.out.println("********send task over");
while(true) {
System.out.println("\n请输入要发送的内容");
final String msgText = input.next();
if ("exit".equals(msgText)) {
System.exit(-1);
} else {
jmsTemplate.send(session -> session.createTextMessage(msgText));
System.out.println(msgText + "\t->|\t发送完成");
}
}
}
}
先启动订阅者，再启动发布者，结果如下：
- 监听器实现消费者不启动直接消费消息
applicationContext.xml 监听器配置：
<!-- 配置Jms消息监听器 -->
<bean id="defaultMessageListenerContainer" class="org.springframework.jms.listener.DefaultMessageListenerContainer">
<!-- Jms连接的工厂 -->
<property name="connectionFactory" ref="connectionFactory"/>
<!-- 设置默认的监听目的地 -->
<property name="destination" ref="destinationTopic"/>
<!--传入默认目的地，可以是queue，也可以是topic-->
<property name="messageListener" ref="myMessageListener"/>
</bean>
自定义监听器：
package com.huazai.activemq.spring.listener;
import org.springframework.stereotype.Component;
import javax.jms.JMSException;
import javax.jms.Message;
import javax.jms.MessageListener;
import javax.jms.TextMessage;
/**
* @author DDKK.COM 弟弟快看，程序员编程资料站
* @date 2022/1/12 0:14
*/
@Component
public class MyMessageListener implements MessageListener {
@Override
public void onMessage(Message message) {
if (message instanceof TextMessage) {
TextMessage textMessage = (TextMessage) message;
try {
System.out.println("消费者收到的消息" + textMessage.getText());
} catch (JMSException e) {
e.printStackTrace();
}
}
}
}
增加了监听器之后，在原来代码基础上
1、 只启动队列生产者；
2、 只启动主题订阅者；
以上两个案例实现了不启动消费者通过监听器实现queue和topic消息消费。
