如何在Java中卸载已加载的类？ [英] How to unload an already loaded class in Java?

问题描述

如何从类加载器中卸载一个类，以便我可以动态使用最近更改的类而无需重新启动我的应用程序（热部署）？是否可以这样做？

How to unload a class from the class loader, so that I can use the recently changed class on the fly without restarting my application (hot deployment)? Is it possible to do that?

推荐答案

Java反叛者即时重新加载已更改的类。有关详细信息，请参见 jrebel网站。由于性能问题，我不知道我会为生产环境推荐这个。当你为服务器重新编译时，JRebel偶尔会把事情搞得一团糟。

Java rebel reloads changed classes on the fly. See the jrebel website for details. I don't know that I would recommend this for a production environment though, because of performance issues. JRebel on occasion bogs things down momentarily when you've recompiled for a server.
