问题 Is there a way to put object in message in camel route process. lets say i have a route from("direct:send") .process(queueProcessor) .to(activemqEndPoint) and in the queueProcessor i am putting an object in the exchange, Now, I have a listener which listens to activemqEndPoint(queue) public void onMessage(Message message) { try { //here i want to get the message i set it in the exchange } Any help?? THanks in advance 回答1: trying this worked for me from("direct:send") .process(queueProcessor)

问题 In the jboss admin-console page I can view the current number of items in my queue. However I'm getting empty enumeration from queueBrowser.getEnumeration().

activeMQ的使用

一.应用场景 在异步处理,并发的业务(比如抢购活动),应用解耦都可以使用到activeMQ 二.RPC框架的局限性 我们使用RPC的框架其实都是点对点的调用,这种架构面对规模和复杂度都越来越高的分布式系统,这些技术也显示出其局限性 1)同步通讯,客户端发出调用后,必须等待服务对象完成处理并返回结果之后才能继续进行; 2)客户和服务对象的生命周期紧密耦合,客户进程和服务对象进程都必须正常运行;如果由于服务对象崩溃或者网络导致用户的请求不可达,客户会受到异常 3)点对点的通讯,客户的一次调用只能发给某个单独的目标对象. 三.消息中心的特点: 1、消息异步接收:消息发送者不需要等待消息接收着的响应,提高整个应用程序的性能 2、消息可靠接收:消息发送出去后保存在一个中间容器内,只有消息接收者收到消息后才删除消息 3、消息队列接收:消息以队列的形式接收,一个一个排队处理 可以指定先后顺序 四.JMS的概念 JMS即Java消息服务(Java Message Service)应用程序接口,是JavaEE平台中关于面向消息中间件(MOM)的API,用于在两个应用程序之间,或分布式系统中发送消息,进行异步通信。 JMS规范 JMS定义了Java中访问消息中心的接口,并没有给予实现,实现JSM接口的消息中心称为JMS Provider,例如ActiveMQ 五.相关的组成 JMS Provide r

消息中间件和JMS的概念

什么是消息中间件? 消息中间件可以理解成就是一个服务软件,保存信息的容器,比如生活中的快递云柜。我们把数据放到消息中间件当中, 然后通知对应的服务进行获取。消息中间件是在 消息的传输过程中保存信息的容器 。 作用 在soa分布式架构系统中,或者企业中的多个项目中,进行 多个系统异步传递消息 。 优点 1.使用消息服务器当做大的队列使用,先进先出,来 处理高并发写入操作 。 2.使用消息服务器可以 将业务系统的串行执行改为并行执行 ,处理效率高,更合理的榨取服务器的性能。 缺点 1.消息中间件 实时性不高 ,因为发送方将消息发送给消息服务器后,消息服务器末必能够立即处理。 2.主要看消息服务器是否繁忙,队列中先进先出,如果数据量大,要排队等待执行。 同步技术 dubbo是一种同步技术, 实时性高, controller调用service项目, 调用就执行。如果service项目中的代码没有执行完, controller里面的代码一致等待结果.。 异步技术 mq消息中间件技术(jms) 是一种异步技术, 消息发送方, 将消息发送给消息服务器。消息服务器未必立即处理.什么时候去处理, 主要看消息服务器是否繁忙,。消息进入服务器后会进入队列中, 先进先出.实时性不高。 什么是JMS? jms的全称叫做Java message service (Java消息服务)

Adding Dynamic Number of Listeners(Spring JMS)

我只是一个虾纸丫 提交于 2020-01-29 05:21:07
问题 I have a requirement to add multiple listeners as mentioned in the application.properties file. Like Below, InTopics=Sample.QUT4,Sample.T05,Sample.T01,Sample.JT7 NOTE: This number can be lot more or less. I am thinking of getting them in an array, @Value("${InTopics}") private String[] inTopics; But i don't know how to create multiple listeners from the array. Currently, for one Topic i am doing as below, @Configuration @EnableJms public class JmsConfiguration { @Value("${BrokerURL}") private
