本文整理了Java中javax.transaction.TransactionManager.suspend()方法的一些代码示例，展示了TransactionManager.suspend()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。TransactionManager.suspend()方法的具体详情如下：
包路径：javax.transaction.TransactionManager
类名称：TransactionManager
方法名：suspend

TransactionManager.suspend介绍

[英]Suspend the association the calling thread has to a transaction, and return the suspended transaction. When returning from this method, the calling thread is no longer associated with a transaction.
[中]挂起调用线程与事务的关联，并返回挂起的事务。从该方法返回时，调用线程不再与事务关联。
