本文整理了Java中com.google.common.io.Resources类的一些代码示例，展示了Resources类的具体用法。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。Resources类的具体详情如下：
包路径：com.google.common.io.Resources
类名称：Resources

Resources介绍

[英]Provides utility methods for working with resources in the classpath. Note that even though these methods use URL parameters, they are usually not appropriate for HTTP or other non-classpath resources.

All method parameters must be non-null unless documented otherwise.
