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();}}}
