1.发送方代码
import com.tfinfo.cim.common.mapper.JsonMapper; import org.slf4j.Logger; import org.slf4j.LoggerFactory; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.beans.factory.annotation.Qualifier; import org.springframework.jms.core.JmsTemplate; import org.springframework.jms.core.MessageCreator; import org.springframework.stereotype.Component; import javax.jms.*; import java.util.Map; import java.util.Map.Entry; import java.util.UUID; /** * * @description 队列消息生产者，发送消息到队列 * */ @Component("queueSender") public class QueueSender { @Autowired @Qualifier("jmsQTemplate_P") private JmsTemplate jmsTemplate; /** * 发送一条Map消息到指定的队列（目标）,参数为对象,转换为json格式字符串后发送 * * @param queueName 队列名称 * @param map 消息内容,map中放入的是需要传递的对象 */ public void send(String queueName, final Map<String, Object> map) { jmsTemplate.send(queueName, new MessageCreator() { @Override public Message createMessage(Session session) throws JMSException { return getMessage(session, map); } }); } /** * 发送一条Map消息到指定的队列（目标）,参数为对象,转换为json格式字符串后发送 * * @param queueName 队列名称 * @param map 消息内容 */ public Message sendWithReply(String queueName, final Map<String, Object> map){ Message replyMsg = jmsTemplate.sendAndReceive(queueName, new MessageCreator() { public Message createMessage(Session session) throws JMSException { return getMessage(session, map); } }); return replyMsg; } private Message getMessage(Session session, Map<String, Object> map) throws JMSException { MapMessage message = session.createMapMessage(); for (Entry<String, Object> entry: map.entrySet()) { String paramkey = entry.getKey(); String paramValue = ""; if(entry.getValue() instanceof String){ paramValue = (String) entry.getValue(); }else{ paramValue = JsonMapper.toJsonString(entry.getValue()); } message.setString(paramkey, paramValue); } return message; } }2.消息回复方代码
public void replayMsg(Message message, Map mqMap) { try { Destination destination = message.getJMSReplyTo(); String queueName = ""; if (destination instanceof Queue) { queueName = ((Queue) destination).getQueueName(); } if(queueName!=null&&!"".equals(queueName)){ queueSender.send(queueName, mqMap); } } catch (JMSException ex) { ex.printStackTrace(); } }
3.jmsQTemplate_P 在Spring中的注入
