JSF中MQ连接的生命周期-连接已关闭 [英] Lifecycle of MQ Connection in JSF - Connection Closed

问题描述

我使用JSF 2和WebSphere MQ for Messaging(JMS).

I use JSF 2 an WebSphere MQ for Messaging (JMS).

我想知道打开/关闭QueueConnection的最佳实践是什么? 我是否应该为每个客户端会话使用一个连接，并在(后)构造上打开它，并在(前)破坏上关闭它，例如

I want to know what's the best practice to open / close the QueueConnection? Should I use for each client session one connection and open it on (post-)construction and close it on (pre-) destruction like here?

还是有更好的方法来处理连接?例如. 在视图中打开EntityManager" JDBC/JPA的模式吗? >

Or are there better ways to handle the connection? E.g. "Open EntityManager in View" Pattern for JDBC/JPA?

推荐答案

避免为每个getMessage()调用创建新的连接.在构造时创建一个连接，并将其另存为实例变量.

Avoid creating a new connection for each getMessage() invocation. Create one connection at construct time, save it as an instance variable.

对于每个getMessage()呼叫，创建一个新会话，获取消息，然后关闭该会话.

For each getMessage() call, create a new session, get the message, then close the session.

完成后，请在销毁时关闭连接.

When you're done, close the connection at destruction time.
