我想在单击按钮时以编程方式重新加载 JSF 使用的 ResourceBundle。类路径中的 ResourceBundle(即 WEB-INF/classes)被外部应用程序修改，修改事件为我所知。
最佳答案
尝试
ResourceBundle.clearCache(Thread.currentThread().getContextClassLoader());
(你可以使用不带参数的相同方法)
来自javadoc
Resource bundle instances created by the getBundle factory methods are cached by default, and the factory methods return the same resource bundle instance multiple times if it has been cached. getBundle clients may clear the cache, manage the lifetime of cached resource bundle instances using time-to-live values, or specify not to cache resource bundle instances. Refer to the descriptions of the getBundle factory method, clearCache, ResourceBundle.Control.getTimeToLive, and ResourceBundle.Control.needsReload for details.
