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

FileUtils.sizeOf介绍

[英]Returns the size of the specified file or directory. If the provided File is a regular file, then the file's length is returned. If the argument is a directory, then the size of the directory is calculated recursively. If a directory or subdirectory is security restricted, its size will not be included.
[中]返回指定文件或目录的大小。如果提供的文件是常规文件，则返回文件的长度。如果参数是目录，则递归计算目录的大小。如果目录或子目录受到安全限制，则不包括其大小。

代码示例

@Override
public long length(URI fileUri)
  throws IOException {
 File file = new File(decodeURI(fileUri.getRawPath()));
 if (file.isDirectory()) {
  throw new IllegalArgumentException("File is directory");
 }
 return FileUtils.sizeOf(file);
}

@Test
public void testCompareSizeOf() {
  final File start = new File("src/test/java");
  final long sizeLong1 = FileUtils.sizeOf(start);
  final BigInteger sizeBig = FileUtils.sizeOfAsBigInteger(start);
  final long sizeLong2 = FileUtils.sizeOf(start);
  assertEquals("Size should not change", sizeLong1, sizeLong2);
  assertEquals("longSize should equal BigSize", sizeLong1, sizeBig.longValue());
}
