我是Spring Integration和JMS的新手，我开始使用它。在这里我想通过activemq创建简单的jms消息并通过弹簧入站适配器（消息驱动）接收它。通过Spring集成入站适配器接收JMS消息随机失败
以下是我的Spring配置文件
<?xml version="1.0" encoding="UTF-8"?>
<beans:beans xmlns="http://www.springframework.org/schema/integration"

<!-- jms beans -->
<beans:bean id="jms.msgQueue" class="org.apache.activemq.command.ActiveMQQueue">
<beans:constructor-arg value="MSG_QUEUE" />
</beans:bean>
<beans:bean name="jms.connectionFactory" class="org.apache.activemq.ActiveMQConnectionFactory">
<beans:property name="brokerURL" value="tcp://localhost:61616" />
</beans:bean>
<!-- spring integration beans -->
<channel id="channels.jms.allMessages">
<queue capacity="1000" />
</channel>
<jms:message-driven-channel-adapter id="adapters.jms.msgAdapter"
connection-factory="jms.connectionFactory"
destination="jms.msgQueue"
channel="channels.jms.allMessages" />
，这是我的测试类
package com.bst.jms;
import javax.jms.Connection;
import javax.jms.ConnectionFactory;
import javax.jms.Destination;
import javax.jms.JMSException;
import javax.jms.MessageProducer;
import javax.jms.Session;
import javax.jms.TextMessage;
import org.springframework.context.support.AbstractApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.integration.Message;
import org.springframework.integration.core.PollableChannel;
public class TestActiveMQ {
public static void main(String[] args){
try{
AbstractApplicationContext context = new ClassPathXmlApplicationContext("app-context.xml");
ConnectionFactory connectionFactory = (ConnectionFactory)context.getBean("jms.connectionFactory");
Destination destination = (Destination)context.getBean("jms.msgQueue");
PollableChannel msgChannel = (PollableChannel) context.getBean("channels.jms.allMessages", PollableChannel.class);
Connection connection = connectionFactory.createConnection();
Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
MessageProducer producer = session.createProducer(destination);
TextMessage textMessage = session.createTextMessage();
textMessage.setText("Message from JMS");
producer.send(textMessage);
System.out.println("--------------- Message Sending ------------------------");
Message<?> received = msgChannel.receive();
String payload = (String) received.getPayload();
System.out.println("Receving message = " + payload);
}catch(JMSException ex){
System.out.println("----------- JMS Exception --------------");
}
}
}
但这事我不能保证交货。在5000毫秒重试 - ：有时程序无法接收消息和一些大部头它有一些警告成功象
Setup of JMS message listener invoker failed for destination 'queue://MSG_QUEUE' - trying to recover. Cause: Connection reset
Could not refresh JMS Connection for destination 'queue://MSG_QUEUE' - retrying in 5000 ms. Cause: Could not connect to broker URL: tcp://localhost:61616. Reason: java.net.ConnectException: Connection refused: connect
无法刷新JMS连接的目标“// MSG_QUEUE队列”。原因：无法连接到代理URL：tcp：// localhost：61616。原因：java.net.ConnectException：连接被拒绝：连接
发生这种情况几次才成功。
你们对此有什么想法。
感谢您的帮助。
