1.代码如下:
- <span style="font-size:18px;background-color:rgb(204,204,204);">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;
-
-
-
-
-
-
-
- public final class FileToZip {
-
- private FileToZip(){}
-
-
-
-
-
-
-
-
- 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++){
-
- ZipEntry zipEntry = new ZipEntry(sourceFiles[i].getName());
- zos.putNextEntry(zipEntry);
-
- 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{
-
- 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!");
- }
- }
-
- }
- </span>
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.
