java文件压缩4

java文件压缩四

在前面的文章中都是将单个文件或者文件夹进行压缩，现在我们可以把不同路劲下的多个文件或者文件夹压缩到一起，生成指定的压缩文件，这里使用的是java自带的压缩方式，不支持中文无乱码：

测试类Test：

package com.home;

import java.io.File;
import java.io.IOException;

public class Test {

	public static void main(String[] args) {
		try {
			ZipUtil.ZipFiles(new File("D:\\test\\test.zip"), new File(
					"D:\\test\\test.pdf"), new File("D:\\test\\test1"),
					new File("D:\\test\\test2"));
		} catch (IOException e) {
			e.printStackTrace();
		}
	}

}

ZipUtil：

package com.home;

import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.util.zip.ZipEntry;
import java.util.zip.ZipOutputStream;

public class ZipUtil {
	/**
	 * 压缩接口
	 * 
	 * @param zip
	 * @param srcFiles
	 * @throws IOException
	 */
	public static void ZipFiles(File zip, File... srcFiles) throws IOException {
		ZipOutputStream zos = null;
		try {
			zos = new ZipOutputStream(new FileOutputStream(zip));
			ZipFiles(zos, "", srcFiles);
		} finally {
			if (zos != null) {
				zos.close();
			}
		}
	}

	/**
	 * 压缩文件
	 * 
	 * @param out
	 * @param path
	 * @param srcFiles
	 */
	private static void ZipFiles(ZipOutputStream out, String path,
			File... srcFiles) {
		path = path.replaceAll("\\*", "/");
		if (!path.endsWith("/")) {
			path += "/";
		}
		byte[] buf = new byte[1024];
		try {
			for (int i = 0; i < srcFiles.length; i++) {
				if (srcFiles[i].isDirectory()) {
					File[] files = srcFiles[i].listFiles();
					String srcPath = srcFiles[i].getName();
					srcPath = srcPath.replaceAll("\\*", "/");
					if (!srcPath.endsWith("/")) {
						srcPath += "/";
					}
					out.putNextEntry(new ZipEntry(path + srcPath));
					ZipFiles(out, path + srcPath, files);
				} else {
					FileInputStream in = new FileInputStream(srcFiles[i]);
					out.putNextEntry(new ZipEntry(path + srcFiles[i].getName()));
					int len;
					while ((len = in.read(buf)) > 0) {
						out.write(buf, 0, len);
					}
					out.closeEntry();
					in.close();
				}
			}
		} catch (Exception e) {
			e.printStackTrace();
		}
	}
}
