Java把文件夹打成压缩包并导出

1.前台调用后台方法export_zip.htm：

@Controllerpublic class AdminController {    private String filePath = AdminController.class.getResource("/").getPath().split("WEB-INF")[0]+ "upload/";        @RequestMapping(value = "export_zip.htm", method = {RequestMethod.GET, RequestMethod.POST })    public void zipwordDownAction(HttpServletRequest request,HttpServletResponse response) throws Exception {        //打包文件的存放路径                             ZipCompressorByAnt zc = new  ZipCompressorByAnt(filePath+ "/file.zip");        //需要打包的文件路径        zc.compress(filePath+ "/file/");        String contentType = "application/octet-stream";        try {            //导出压缩包            download(request, response, "upload/file.zip", contentType,encodeChineseDownloadFileName(request, "file.zip"));        } catch (Exception e) {            request.getSession().setAttribute("msg", "暂无内容");        }        //如果原压缩包存在,则删除        File file=new File(filePath+ "/file.zip");        if(file.exists()){            file.delete();         }    }       /**      * 下载文件       */      public static void download(HttpServletRequest request,HttpServletResponse response, String storeName, String contentType,String realName) throws Exception {        response.setContentType("text/html;charset=UTF-8");        request.setCharacterEncoding("UTF-8");        BufferedInputStream bis = null;        BufferedOutputStream bos = null;        String ctxPath =FileUtil.class.getResource("/").getPath().split("WEB-INF")[0];        String downLoadPath = ctxPath + storeName;        long fileLength = new File(downLoadPath).length();        response.setContentType(contentType);        response.setHeader("Content-disposition", "attachment; filename="                + new String(realName.getBytes("utf-8"), "ISO8859-1"));        response.setHeader("Content-Length", String.valueOf(fileLength));        bis = new BufferedInputStream(new FileInputStream(downLoadPath));        bos = new BufferedOutputStream(response.getOutputStream());        byte[] buff = new byte[2048];        int bytesRead;        while (-1 != (bytesRead = bis.read(buff, 0, buff.length))) {            bos.write(buff, 0, bytesRead);        }        bis.close();        bos.close();    }    /**      * 对文件流输出下载的中文文件名进行编码 屏蔽各种浏览器版本的差异性       */      public static String encodeChineseDownloadFileName(HttpServletRequest request, String pFileName) throws UnsupportedEncodingException {           String filename = null;                String agent = request.getHeader("USER-AGENT");                if (null != agent){                    if (-1 != agent.indexOf("Firefox")) {//Firefox                        filename = "=?UTF-8?B?" + (new String(org.apache.commons.codec.binary.Base64.encodeBase64(pFileName.getBytes("UTF-8"))))+ "?=";                    }else if (-1 != agent.indexOf("Chrome")) {//Chrome                        filename = new String(pFileName.getBytes(), "ISO8859-1");                    } else {//IE7+                        filename = java.net.URLEncoder.encode(pFileName, "UTF-8");                        filename = StringUtils.replace(filename, "+", "%20");//替换空格                    }                } else {                    filename = pFileName;                }                return filename;       }  

2.调用工具类：

import java.io.File;import org.apache.tools.ant.Project;import org.apache.tools.ant.taskdefs.Zip;import org.apache.tools.ant.types.FileSet;public class ZipCompressorByAnt {    private File zipFile;      public ZipCompressorByAnt(String pathName) {          zipFile = new File(pathName);      }      public void compress(String srcPathName) {          File srcdir = new File(srcPathName);          if (!srcdir.exists())              throw new RuntimeException(srcPathName + "不存在！");          Project prj = new Project();          Zip zip = new Zip();              zip.setProject(prj);          zip.setDestFile(zipFile);          FileSet fileSet = new FileSet();          fileSet.setProject(prj);           fileSet.setDir(srcdir);          //fileSet.setIncludes("**/*.java"); 包括哪些文件或文件夹 eg:zip.setIncludes("*.java");          //fileSet.setExcludes(...); 排除哪些文件或文件夹          zip.addFileset(fileSet);                    zip.execute();      }  }
