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();        }    }}
