电脑怎么压缩文件成zip格式怎么压缩文件成zip格式 _云知道

一、导入相关依赖包
<dependency><groupId>org.apache.ant</groupId><artifactId>ant</artifactId><version>1.8.1</version></dependency>

二、创建相应的工具类

import java.io.BufferedOutputStream;import java.io.File;import java.io.FileOutputStream;import java.io.IOException;import java.io.InputStream;import java.util.ArrayList;import java.util.Enumeration;import java.util.List;import com.xxx.xxx.entity.xxx.WkcrWord;import org.apache.tools.zip.ZipEntry;import org.apache.tools.zip.ZipFile;/** * 解压文件的工具类 */public class ZipUtil {/*** 解压文件* @param directory 文件目录* @param zip 文件zip的压缩包*/public static List<WkcrWord> unZipFile(String directory, File zip) {List<WkcrWord> filePathList=new ArrayList<>();try {int count;int buffer = 2048;File file;InputStream is;FileOutputStream fos;BufferedOutputStream bos;//根据不同环境，不同的文件 ， 需要使用到不同的编码格式ZipFile zipFile = new ZipFile(zip, "GBK");Enumeration en = zipFile.getEntries();createFolder(directory);while (en.hasMoreElements()) {byte buf[] = new byte[buffer];ZipEntry entry = (ZipEntry) en.nextElement();//获取压缩包中的文件的名字String fileName = entry.getName();if(fileName.contains("/")){fileName=fileName.substring(fileName.lastIndexOf("/")+1);}String filePath = directory + fileName;//根据业务逻辑创建相应的实体类WkcrWord wkcrWord=new WkcrWord();wkcrWord.setName(fileName);wkcrWord.setWordUrl(filePath);//根据不同的文件后缀设置正则表达式String compile = ".*.doc.*|.*.docx.*";//符合的保存if(filePath.matches(compile)){filePathList.add(wkcrWord);}if(entry.isDirectory()){createFolder(filePath);}else{file = new File(filePath);file.createNewFile();is = zipFile.getInputStream(entry);fos = new FileOutputStream(file);bos = new BufferedOutputStream(fos, buffer);while ((count = is.read(buf)) > -1) {bos.write(buf, 0, count);}bos.close();fos.close();is.close();}}zipFile.close();//遍历当前上传的word进行转化为html进行相应的保存filePathList.stream().forEach(wkcrWord-> wkcrWord.setWordTxt(DocTableReadUtil.saveWord(wkcrWord.getWordUrl(),wkcrWord.getName())));} catch (IOException e) {e.printStackTrace();}finally {zip.delete();}return filePathList;}/*** 创建目录* @param path 文件的目录*/private static void createFolder(String path) {try {File uploadFilePath = new File(path);if (uploadFilePath.exists() == false) {uploadFilePath.mkdirs();}} catch (Exception ex) {ex.printStackTrace();}}}
