我从不工作JMS。最近我在所有文件中下载Activemq并更改了端口号。我从61616命令提示符运行以下命令并在浏览器上打开控制台页面。61617conf/activemq-*.xml
C:\Users\Infratab Bangalore\Desktop\Queueing\apache-activemq-5.8.0\bin>activemq
现在我想使用JMSto从 java 代码发送消息Activemq。为此，我编写了以下代码。并使用 Apache Tomcat 服务器运行我的代码。它不起作用
此代码在 Eclipse 中实现。
package PackageName;
import java.io.IOException;
import javax.jms.Connection;
import javax.jms.ConnectionFactory;
import javax.jms.Queue;
import javax.jms.Session;
import javax.jms.TextMessage;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.activemq.ActiveMQConnectionFactory;
public class MessageProducer extends HttpServlet {
@Override
protected void service(HttpServletRequest arg0, HttpServletResponse arg1) throws ServletException, IOException {
try {
//created ConnectionFactory object for creating connection
ConnectionFactory factory = new ActiveMQConnectionFactory("admin", "admin", "tcp://localhost:61617");
//Establish the connection
Connection connection = factory.createConnection();
Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
Queue queue = session.createQueue("Test");
//Added as a producer
javax.jms.MessageProducer producer = session.createProducer(queue);
// Create and send the message
TextMessage msg = session.createTextMessage();
msg.setText("TestMessage");
producer.send(msg);
} catch (Exception e) {
// TODO: handle exception
}
}
}
我收到以下错误
java.lang.NoClassDefFoundError: org/apache/commons/logging/LogFactory
org.apache.activemq.ActiveMQPrefetchPolicy.<clinit>(ActiveMQPrefetchPolicy.java:30)
org.apache.activemq.ActiveMQConnectionFactory.<init>(ActiveMQConnectionFactory.java:88)
PackageName.MessageProducer.service(MessageProducer.java:20)
javax.servlet.http.HttpServlet.service(HttpServlet.java:723)
你能建议我吗，我在哪里写错了。
谢谢。
