我正在关注有关 JMS 的教程。
package org.dedunu.jms.chapter02;
import javax.jms.ConnectionFactory;
import javax.jms.JMSContext;
import javax.jms.Queue;
public class JMS2Receiver {
public static void main(String[] args) {
ConnectionFactory connectionFactory = new com.sun.messaging.ConnectionFactory();
try(JMSContext jmsContext = connectionFactory.createContext();){
Queue queue = jmsContext.createQueue("TRADE");
String body = jmsContext.createConsumer(queue).receiveBody(String.class);
System.out.println(body);
}
}
}
Maven依赖列表:
<dependencies>
<dependency>
<groupId>javax</groupId>
<artifactId>javaee-api</artifactId>
<version>7.0</version>

但它失败了,但有以下例外:
Exception in thread "main" java.lang.AbstractMethodError: com.sun.messaging.ConnectionFactory.createContext()Ljavax/jms/JMSContext;
at org.dedunu.jms.chapter02.JMS2Sender.main(JMS2Sender.java:10)
如果我从 OpenMQ 分发中添加 jms.jar 和 imq.jar,则此示例可以正常工作。但是对于 Maven,它不会。我认为问题应该是由 Maven 引起的。
