[英]Spring Tomcat configuration for JMS (IBM MQ, Tomcat, Spring)
I have a relatively old application that uses Websphere MQ for messaging. 我有一个使用Websphere MQ进行消息传递的相对较旧的应用程序。 It runs on WAS (Websphere Application Server) and uses MDBs (Message Driven Beans). 它运行在WAS(Websphere应用程序服务器)上,并使用MDB(消息驱动Bean)。 I have to migrate that application from Websphere so Tomcat 我必须从Websphere迁移该应用程序,以便Tomcat
I tried something using springboot and was able to write a sample JMS application that connects to queues and read messages and is able to process them but have not implemented transaction management with JMS. 我使用springboot进行了一些尝试,并且能够编写一个示例JMS应用程序,该应用程序连接到队列并读取消息,并且能够处理它们,但尚未使用JMS实现事务管理。 Now I have been asked to configure the application so that it runs on tomcat. 现在,我被要求配置该应用程序,以便它在tomcat上运行。 Can anyone please help, how and where I have to setup configuration in tomcat. 任何人都可以帮忙,我在tomcat中如何以及在哪里设置配置。 Or what all changes will be required if package my springboot application as war and deploy it on Tomcat. 或者,如果将springboot应用程序打包为war并将其部署在Tomcat上,那么将需要进行哪些更改。
This is how my code in applicationconfig.java looks like 这就是我在applicationconfig.java中的代码的样子
