如何使Spring JMS从注解@JmsListener中选择目标队列名称 [英] How to make Spring JMS pick destination queue name from annotation @JmsListener

问题描述

任何帮助将不胜感激.我正在尝试使用Spring JMSListener创建MDB的替代品.我希望将目的地名称作为注释传递，但我注意到org.springframework.jms.listener.DefaultMessageListenerContainer容器配置中必须包含destinationName或destination.我想念什么吗?如何使用目标解析器来使用@JmsListener批注中的队列名称?

Any help will be greatly appreciated. I am trying to create a replacement for MDB with spring JMSListener. I wanted the destination name to be passed as a annotation, but i noticed that org.springframework.jms.listener.DefaultMessageListenerContainer container config has destinationName or destination as mandatory. Am i missing something ? How to make use of destination resolver to use queue name from @JmsListener annotation?

@Component 
public class InitStRspnLstnr {

@JmsListener(destination = "${xyz.company.MQ.INITST.RSPN.FADS.Q}")
public void onMessage(Message msg) throws JMSException {
    System.out.println("**********************************************"+msg);
}}

下面是我粘贴的Xml，我现在评论了该容器，因为spring试图连接到虚拟队列而不是注释中的那个.

Below is my Xml pasted, I commented the container for now, since spring was trying to connect to dummy queue instead of the one in annotation..

推荐答案

在下面添加了工作版本. xml中不需要defaultDestinationName，如果它是通过注释在代码中设置的.${company.project.MQ.module.Q}和其他值是从属性文件加载的，则也可以进行硬编码.

Added working version below. defaultDestinationName is not needed in xml , if its set up in code via annotation.. ${company.project.MQ.module.Q} and other values are loaded from properties file, it can be hard coded too.

@Component 
public class SampleLstner{     
@JmsListener(concurrency = "1", destination = "${company.project.MQ.module.Q}", containerFactory = "jmsListenerContainerFactory")
           public void onMessage(Message msg) throws JMSException {}
 }
