将Spring Application Context传递给与请求关联的ThreadLocal是否安全? [英] Is it safe to pass in the Spring Application Context into a ThreadLocal associated with a request?

问题描述

在JPA中，我想利用带注释的PrePersist方法执行一些操作，而不是完成实现Singleton模式(使用getInstance()等)所需的工作，我想知道是否将Spring ApplicationContext通过一个ThreadLocal(在请求后我将其关闭)将是安全的.我只是在getBean(Support.class)上使用它，而不修改上下文.

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.

推荐答案

如果您可以使用Hibernate事件侦听器，我会在此处编写一次响应，并提供一种针对Spring托管事件侦听器的可能方法:

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

使用Hibernate 4的Integrator模式和Spring的依赖注入
