1.代码如下：
package cn.gov.csrc.base.util;import java.io.BufferedInputStream;import java.io.BufferedOutputStream;import java.io.File;import java.io.FileInputStream;import java.io.FileNotFoundException;import java.io.FileOutputStream;import java.io.IOException;import java.util.zip.ZipEntry;import java.util.zip.ZipOutputStream;/*** 将文件夹下面的文件* 打包成zip压缩文件* * @author admin**/public final class FileToZip {private FileToZip(){}/*** 将存放在sourceFilePath目录下的源文件，打包成fileName名称的zip文件，并存放到zipFilePath路径下* @param sourceFilePath :待压缩的文件路径* @param zipFilePath :压缩后存放路径* @param fileName :压缩后文件的名称* @return*/public static boolean fileToZip(String sourceFilePath,String zipFilePath,String fileName){boolean flag = false;File sourceFile = new File(sourceFilePath);FileInputStream fis = null;BufferedInputStream bis = null;FileOutputStream fos = null;ZipOutputStream zos = null;if(sourceFile.exists() == false){System.out.println("待压缩的文件目录："+sourceFilePath+"不存在.");}else{try {File zipFile = new File(zipFilePath + "/" + fileName +".zip");if(zipFile.exists()){System.out.println(zipFilePath + "目录下存在名字为:" + fileName +".zip" +"打包文件.");}else{File[] sourceFiles = sourceFile.listFiles();if(null == sourceFiles || sourceFiles.length<1){System.out.println("待压缩的文件目录：" + sourceFilePath + "里面不存在文件，无需压缩.");}else{fos = new FileOutputStream(zipFile);zos = new ZipOutputStream(new BufferedOutputStream(fos));byte[] bufs = new byte[1024*10];for(int i=0;i<sourceFiles.length;i++){//创建ZIP实体，并添加进压缩包ZipEntry zipEntry = new ZipEntry(sourceFiles[i].getName());zos.putNextEntry(zipEntry);//读取待压缩的文件并写进压缩包里fis = new FileInputStream(sourceFiles[i]);bis = new BufferedInputStream(fis, 1024*10);int read = 0;while((read=bis.read(bufs, 0, 1024*10)) != -1){zos.write(bufs,0,read);}}flag = true;}}} catch (FileNotFoundException e) {e.printStackTrace();throw new RuntimeException(e);} catch (IOException e) {e.printStackTrace();throw new RuntimeException(e);} finally{//关闭流try {if(null != bis) bis.close();if(null != zos) zos.close();} catch (IOException e) {e.printStackTrace();throw new RuntimeException(e);}}}return flag;}public static void main(String[] args){String sourceFilePath = "D:\\TestFile";String zipFilePath = "D:\\tmp";String fileName = "12700153file";boolean flag = FileToZip.fileToZip(sourceFilePath, zipFilePath, fileName);if(flag){System.out.println("文件打包成功!");}else{System.out.println("文件打包失败!");}}}
2.结果如下：
文件打包成功!
3.到D:/tmp下查看，你会发现生成了一个zip压缩包.
