java 实现多个文件的Zip包的生成

最近在项目中遇到多个文件的达成Zip包，由于对这块不熟，在网上找到一个，现在忘了找的谁的，如果您发现了，请告诉我你的链接，我指明出处

下面是相关代码：

package run.utils;
import java.io.BufferedInputStream;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.util.zip.CRC32;
import java.util.zip.CheckedOutputStream;
import java.util.zip.ZipEntry;
import java.util.zip.ZipOutputStream;

public class ZipCompressor {
    static final int BUFFER = 8192;   

    private File zipFile;   

    public ZipCompressor(String pathName) {
        zipFile = new File(pathName);
    }
    public void compress(String... pathName) {
    	ZipOutputStream out = null;
    	try {
			FileOutputStream fileOutputStream = new FileOutputStream(zipFile);
			CheckedOutputStream cos = new CheckedOutputStream(fileOutputStream,
					new CRC32());
			out = new ZipOutputStream(cos);
			String basedir = "";
			for (int i=0;i<pathName.length;i++){
				compress(new File(pathName[i]), out, basedir);
			}
	    	out.close();
    	} catch (Exception e) {
			throw new RuntimeException(e);
		}
    }
    public void compress(String srcPathName) {
        File file = new File(srcPathName);
        if (!file.exists())
            throw new RuntimeException(srcPathName + "不存在！");
        try {
            FileOutputStream fileOutputStream = new FileOutputStream(zipFile);
            CheckedOutputStream cos = new CheckedOutputStream(fileOutputStream,
                    new CRC32());
            ZipOutputStream out = new ZipOutputStream(cos);
            String basedir = "";
            compress(file, out, basedir);
            out.close();
        } catch (Exception e) {
            throw new RuntimeException(e);
        }
    }   

    private void compress(File file, ZipOutputStream out, String basedir) {
        /* 判断是目录还是文件 */
        if (file.isDirectory()) {
            System.out.println("压缩：" + basedir + file.getName());
            this.compressDirectory(file, out, basedir);
        } else {
            System.out.println("压缩：" + basedir + file.getName());
            this.compressFile(file, out, basedir);
        }
    }   

    /** 压缩一个目录 */
    private void compressDirectory(File dir, ZipOutputStream out, String basedir) {
        if (!dir.exists())
            return;   

        File[] files = dir.listFiles();
        for (int i = 0; i < files.length; i++) {
            /* 递归 */
            compress(files[i], out, basedir + dir.getName() + "/");
        }
    }   

    /** 压缩一个文件 */
    private void compressFile(File file, ZipOutputStream out, String basedir) {
        if (!file.exists()) {
            return;
        }
        try {
            BufferedInputStream bis = new BufferedInputStream(
                    new FileInputStream(file));
            ZipEntry entry = new ZipEntry(basedir + file.getName());
            out.putNextEntry(entry);
            int count;
            byte data[] = new byte[BUFFER];
            while ((count = bis.read(data, 0, BUFFER)) != -1) {
                out.write(data, 0, count);
            }
            bis.close();
        } catch (Exception e) {
            throw new RuntimeException(e);
        }
    }
   public static void main(String[] args) {
        ZipCompressor zc = new ZipCompressor("C:/Users/wj/Desktop/aaa.zip");
        zc.compress("C:/Users/wj/Desktop/water.js","C:/Users/wj/Desktop/index.jsp");
    }
