英文:
Is it safe to pass in the Spring Application Context into a ThreadLocal associated with a request?
问题
在JPA中，我想利用PrePersist注解的方法来执行一些操作，但与其实现Singleton模式（使用getInstance()等）要做的事情，我在想是否可以通过ThreadLocal传递Spring ApplicationContext来实现，然后在请求结束后关闭释放它，这样做是否安全。我主要只是使用它来getBean(Support.class)，而不修改上下文。
英文:
In JPA I want to utilize the PrePersist annotated method to perform some operations but rather than making the things it needs to implement the Singleton pattern (with getInstance() etc.) I was wondering if I pass the Spring ApplicationContext through a ThreadLocal (which I close release after the request) would be a safe thing to do so. I am only using it primarilly to getBean(Support.class) and not modifying the context.

如果您可以使用我曾经编写的Hibernate事件监听器，我曾经在以下链接中提供了一种可能的Spring托管事件监听器的方法：

If you can use Hibernate event listeners I wrote once a response with a possible approach for Spring managed event listeners here:
