本文整理了Java中org.slf4j.LoggerFactory.getLogger()方法的一些代码示例，展示了LoggerFactory.getLogger()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。LoggerFactory.getLogger()方法的具体详情如下：
包路径：org.slf4j.LoggerFactory
类名称：LoggerFactory
方法名：getLogger

LoggerFactory.getLogger介绍

[英]Return a logger named corresponding to the class passed as parameter, using the statically bound ILoggerFactory instance.
[中]使用静态绑定的iLogger工厂实例，返回与作为参数传递的类相对应的名为的记录器。
