类名称：LogManager
方法名：setFactory

LogManager.setFactory介绍

[英]Sets the current LoggerContextFactory to use. Normally, the appropriate LoggerContextFactory is created at startup, but in certain environments, a LoggerContextFactory implementation may not be available at this point. Thus, an alternative LoggerContextFactory can be set at runtime.

Note that any Logger or LoggerContext objects already created will still be valid, but they will no longer be accessible through LogManager. Thus, it is a bad idea to use this method without a good reason! Generally, this method should be used only during startup before any code starts caching Logger objects.
[中]设置要使用的当前LoggerContextFactory。通常，在启动时会创建相应的LoggerContextFactory，但在某些环境中，此时可能无法使用LoggerContextFactory实现。因此，可以在运行时设置另一个LoggerContextFactory。
请注意，已经创建的任何Logger或LoggerContext对象仍然有效，但它们将不再可以通过LogManager访问。因此，在没有充分理由的情况下使用这种方法是个坏主意！通常，在任何代码开始缓存记录器对象之前，仅应在启动期间使用此方法。
