本文整理了Java中javax.jms.Connection.start()方法的一些代码示例，展示了Connection.start()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Connection.start()方法的具体详情如下：
包路径：javax.jms.Connection
类名称：Connection
方法名：start

Connection.start介绍

[英]Starts (or restarts) a connection's delivery of incoming messages. A call to start on a connection that has already been started is ignored.
[中]启动（或重新启动）连接传入消息的传递。对已启动的连接的启动调用将被忽略。
