Apache Commons IO 2.1 发布

     Commons项目中用来处理IO的一些工具类包，下面是一些示例代码：    <pre class="brush:java; toolbar: true; auto-links: false;">//直接将IO流转成字符串   InputStream in = new URL( "http://jakarta.apache.org" ).openStream();   try {     System.out.println( IOUtils.toString( in ) );   } finally {     IOUtils.closeQuietly(in);   }  //读取文本文件的所有行   File file = new File("/commons/io/project.properties");   List lines = FileUtils.readLines(file, "UTF-8");  //路径处理   String filename = "C:/commons/io/../lang/project.xml";   String normalized = FilenameUtils.normalize(filename);   // result is "C:/commons/lang/project.xml"  //获取目录空间   long freeSpace = FileSystemUtils.freeSpace("C:/");   //打印文件的所有行   LineIterator it = FileUtils.lineIterator(file, "UTF-8");   try {     while (it.hasNext()) {       String line = it.nextLine();       /// do something with line     }   } finally {     LineIterator.closeQuietly(iterator);   }</pre>    <p>Apache Commons IO 2.1 发布了，这是从 2.0.1 版本直接升级，包括7个新特性以及一些bug修复。</p>    <p><strong>新特性：</strong></p>    <p>o Use standard Maven directory layout <br /> o Add IOUtils API toString for URL and URI to get contents <br /> o Add API FileUtils.copyFile(File input, OutputStream output)<br /> o FileAlterationObserver has no getter for FileFilter<br /> o Add FileUtils.getFile API with varargs parameter<br /> o Add new APPEND parameter for writing string into files<br /> o Add new read method "toByteArray" to handle InputStream with known size.</p>    <p><strong>修复的bug：</strong></p>    <p>o Dubious use of mkdirs() return code<br /> o ReaderInputStream enters infinite loop when it encounters an unmappable character<br /> o FileUtils.moveFile() JavaDoc should specify FileExistsException thrown<br /> o ClassLoaderObjectInputStream does not handle Proxy classes<br /> o Tailer returning partial lines when reaching EOF before EOL<br /> o FileUtils.copyFile() throws IOException when copying large files to a shared directory (on Windows)<br /> o FileSystemUtils.freeSpaceKb throws exception for Windows volumes with no visible files.</p>    <p>下载地址：<a href="/misc/goto?guid=4958192953776425315" target="_blank">http://commons.apache.org/io/download_io.cgi</a></p>
