java实现基于activeMQ的消息推送
此⽂章是基于 
⼀. jar包介绍
  1. 下载 apache-activemq-5.3.0，得到：
activemq-all-5.3.0.jar
activemq-web-5.3.0.jar
2. spring-framework-4.
3.
4.RELEASE 的 libs ⽂件夹下得到：
spring-jms-4.3.4.RELEASE.jar
⼆. 相关程序代码

  2. JmsSender.java，消息发送器接⼝
package com.ims.interfaces.jms.activeMQ;
public interface JmsSender {
public void send(final MsgContext context);
}
View Code
  3. JmsSenderImpl.java，消息发送器实现
package com.ims.interfaces.jms.activeMQ;
import javax.jms.Destination;
import javax.jms.JMSException;
import javax.jms.Message;
import javax.jms.ObjectMessage;
import javax.jms.Session;
import org.JmsTemplate;
import org.MessageCreator;
public class JmsSenderImpl implements JmsSender{
private JmsTemplate jmsTemplate;
/**
* 消息通告队列，表⽰点到点通讯模型
*/
private Destination msgQueue;
/**
* 发送消息
* @param context 消息上下⽂
*/
public void send(final MsgContext context) {
getJmsTemplate().send(getMsgQueue(), new MessageCreator() { public Message createMessage(Session session) throws JMSException {
final ObjectMessage message = ateObjectMessage();
message.setObject(context);
return message;
}
});
}
public JmsTemplate getJmsTemplate() {
return jmsTemplate;
}
public void setJmsTemplate(JmsTemplate jmsTemplate) {
this.jmsTemplate = jmsTemplate;
}
public Destination getMsgQueue() {
return msgQueue;
}
public void setMsgQueue(Destination msgQueue) {
this.msgQueue = msgQueue;
}
}

  4. MsgContext.java，消息上下⽂类
package com.ims.interfaces.jms.activeMQ;
import java.io.Serializable;
import java.util.Collection;
public class MsgContext implements Serializable{
private static final long serialVersionUID = -7877770277875813295L;
/**
* 消息接收者
*/
private final Collection<String> users;
/**
* 发送的消息
*/
private final String message;
/**activemq默认账号密码
* 发送的⽅式
*/
private final Collection<String> modes;
public MsgContext(Collection<String> users, String message,
Collection<String> modes){
this.users = users;
}
public Collection<String> getUsers() {
return users;
}
public String getMessage() {
return message;
}
public Collection<String> getModes() {
return modes;
}
}

  5. MsgListener.java，消息监听、执⾏器
package com.ims.interfaces.jms.activeMQ;
import javax.jms.JMSException;
import javax.jms.Message;
import javax.jms.MessageListener;
import javax.jms.ObjectMessage;
import org.springframework.jms.support.JmsUtils;
public class MsgListener implements MessageListener{
/**
* 监听到有消息时，执⾏的操作
* @param msg 消息对象
*/
@Override
public void onMessage(Message message) {
if(message == null) { return; }
// 获取对象消息
final ObjectMessage objectMessage = (ObjectMessage) message;
// 消息上下⽂
MsgContext context = null;
try {
// 从对象消息中获取消息上下⽂对象
context = (MsgContext) Object();
}catch (JMSException e) {
return;
}
System.out.Message());
if(context==null || Modes()==null || Modes().size()==0){
return;
}
// 取到消息上下⽂后，可执⾏⾃定义操作
}
}

  6. TestController.java，测试jms消息发送
package com.ller;
import java.util.Collection;
import java.util.HashSet;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.servlet.ModelAndView;
import com.imsmon.ServiceLocator;
import com.ims.interfaces.jms.activeMQ.JmsSender;
import com.ims.interfaces.jms.activeMQ.MsgContext;
@Controller
@RequestMapping("test")
public class TestController extends BaseController{
@RequestMapping("view")
public ModelAndView test(){
ModelAndView view = new ModelAndView("test.jsp");
return view;
}
@RequestMapping("jms!send")
public void send(@RequestParam String msg){
JmsSender jmsSender = Service("jmsSender");
Collection<String> users = new HashSet<String>();
Collection<String> modes = new HashSet<String>();
MsgContext msgContext = new MsgContext(users, msg, modes);
jmsSender.send(msgContext);
}
}

  7. jms.jsp，测试jms消息发送

三. 测试
  2. 输⼊消息内容，点击发送，MsgListener 类会在后台输出消息内容
