本文介绍了一个简单的文件压缩工具实现方法，使用Java语言演示了如何将指定目录下的所有文件及子目录压缩成一个ZIP文件。该工具能够递归地处理目录内的文件，并保持原有的文件结构。

无描述，有代码，你懂的

	public static void zip() throws FileNotFoundException, IOException {
		File root = new File("svn-1.6");
		ZipOutputStream zipOutputStream = new ZipOutputStream(new FileOutputStream(root.getPath()+".zip"));
		
		zipDirectory(root,zipOutputStream);
		
		zipOutputStream.close();
	}
	
	private static void zipDirectory(File root,ZipOutputStream zipOutputStream) throws IOException{
		String zipPath = "";
		zipDirectory(zipPath,root,zipOutputStream);
	}
	
	private static void zipDirectory(String basePath,File root,ZipOutputStream zipOutputStream) throws IOException{
		if(basePath.length()>0){
			basePath += "/";
		}
		File[] files = root.listFiles();
		for (int i = 0; i < files.length; i++) {
			File file = files[i];
			if(file.isFile()){
				System.out.println(file.getPath());
				ZipEntry zipEntry = new ZipEntry(basePath + file.getName());
				zipOutputStream.putNextEntry(zipEntry);
				
				FileInputStream inputStream = new FileInputStream(file);
				int count;byte[] buffer = new byte[1024];
				while((count = inputStream.read(buffer, 0, buffer.length))>0){
					zipOutputStream.write(buffer, 0, count);
				}
				inputStream.close();
			}else if(file.isDirectory()){
				ZipEntry zipEntry = new ZipEntry(basePath + file.getName()+"/");
				zipOutputStream.putNextEntry(zipEntry);
				zipDirectory(basePath + file.getName(),file,zipOutputStream);
			}
		}
	}
