本文整理了Java中java.lang.Class.getResourceAsStream()方法的一些代码示例，展示了Class.getResourceAsStream()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。Class.getResourceAsStream()方法的具体详情如下：
包路径：java.lang.Class
类名称：Class
方法名：getResourceAsStream

Class.getResourceAsStream介绍

[英]Returns a read-only stream for the contents of the given resource, or null if the resource is not found. The mapping between the resource name and the stream is managed by the class' class loader.
[中]返回给定资源内容的只读流，如果找不到资源，则返回null。资源名称和流之间的映射由类的类装入器管理。

/**
  * Returns an InputStream for the given test class and sub-path.
  *
  * @param testClass A Junit test class.
  * @param subPath   The sub-path under androidTest/resources where the desired resource is
  *                  located. Should not be prefixed with a '/'

 public static InputStream openResource(Class<?> testClass, String subPath) {
  return testClass.getResourceAsStream("/" + subPath);

// From ClassLoader, all paths are "absolute" already - there's no context
// from which they could be relative. Therefore you don't need a leading slash.
InputStream in = this.getClass().getClassLoader()
                .getResourceAsStream("SomeTextFile.txt");
// From Class, the path is relative to the package of the class unless
// you include a leading slash, so if you don't want to use the current
// package, include a slash like this:
InputStream in = this.getClass().getResourceAsStream("/SomeTextFile.txt");
