本文整理了Java中org.apache.commons.io.IOUtils.toByteArray()方法的一些代码示例，展示了IOUtils.toByteArray()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。IOUtils.toByteArray()方法的具体详情如下：
包路径：org.apache.commons.io.IOUtils
类名称：IOUtils
方法名：toByteArray

IOUtils.toByteArray介绍

[英]Get the contents of an InputStream as a byte[].

This method buffers the input internally, so there is no need to use a BufferedInputStream.
[中]将InputStream的内容作为byte[]获取。
此方法在内部缓冲输入，因此无需使用BufferedInputStream。

代码示例

/**
 * Gets the contents of a <code>URI</code> as a <code>byte[]</code>.
 *
 * @param uri the <code>URI</code> to read
 * @return the requested byte array
 * @throws NullPointerException if the uri is null
 * @throws IOException          if an I/O exception occurs
 * @since 2.4
 */
public static byte[] toByteArray(final URI uri) throws IOException {
  return IOUtils.toByteArray(uri.toURL());
}
