Spring整合ActiveMQ接收消息

操作步骤

第一步：把Activemq相关的jar包，添加到工程中
第二步：创建一个MessageListener的实现类，负责监听
第三步：配置MessageListener监听器
第四步：初始化Spring容器，进行监听

添加jar包

<!-- activemq的jar包 -->
<dependency>
    <groupId>org.apache.activemq</groupId>
    <artifactId>activemq-all</artifactId>
</dependency>

创建监听器

创建MessageListener对象
用于接收消息

public class MyMessageListener implements MessageListener {

    @Override
    public void onMessage(Message message) {
        try {
            // 接收到消息
            TextMessage textMessage = (TextMessage) message;
            String text = textMessage.getText();
            System.out.println(text);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

}

配置监听器

配置MessageListener
添加配置文件
applicationContext-activemq.xml

加载配置文件

初始化Spring容器
进行监听

public class TestSpringActiveMq {

    @Test
    public void testSpringActiveMq() throws Exception {
        //初始化spring容器
        ApplicationContext applicationContext = new ClassPathXmlApplicationContext("classpath:spring/applicationContext-activemq.xml");
        //等待
        System.in.read();
    }
}
