1.本文只提供了一個功能的代碼

public String addFreeMarker() throws Exception {HttpSession session = request.getSession();User user = (User) session.getAttribute(Constant.USER_SESSION_KEY);String realName = user.getRealName();System.out.println("--------獲取登錄用戶信息:------------"+realName);/* 截取后綴名 */if (StringUtil.isEmpty(fileName)) {throw new Exception("文件不能為空");}int pos = fileName.lastIndexOf(".");String str = fileName.substring(pos+1).toLowerCase();//判斷上傳文件必須是zip或者是rar否則不允許上傳if (StringUtil.isEmpty(str)||(!str.equals("zip")&&!str.equals("rar")&&!str.equals("png")&&!str.equals("jpg")&&!str.equals("gif"))) {throw new Exception("上傳文件格式錯誤，請重新上傳");}// 時間加后綴名保存saveName = new Date().getTime() + "."+str;//文件名saveFileName = saveName.substring(0, saveName.lastIndexOf("."));// 根據服務器的文件保存地址和原文件名創建目錄文件全路徑File imageFile = new File(ServletActionContext.getServletContext().getRealPath("upload")+ "/" +saveFileName+"/"+ saveName);File descFile = new File(ServletActionContext.getServletContext().getRealPath("upload")+"/"+saveFileName);if (!descFile.exists()) {descFile.mkdirs();}//解壓目的文件String descDir = ServletActionContext.getServletContext().getRealPath("upload")+"/"+saveFileName+"/";copy(myFile, imageFile);//自己生成主鍵Long seqNo = freemarkerService.getOrderNumberSeq();String orderNumber = RandomIdGenerator.generatorOrderNumber(seqNo);HttpServletRequest httpRequest=(HttpServletRequest)request;String httpURL = "http://" + request.getServerName() //服務器地址 + ":" + request.getServerPort() //端口號 + httpRequest.getContextPath(); //項目名稱 String URL = httpURL+"/"+"upload"+"/"+saveFileName+"/"+saveName;System.out.println("============訪問地址是：============="+ URL);//獲取用戶信息 freemarker.setFilesId(orderNumber);freemarker.setAuthor(realName);freemarker.setFilesName(saveFileName);freemarker.setFilesUrl(URL);//開始解壓zipif (str.equals("zip")) {CompressFileUits.unZipFiles(imageFile, descDir);//文件解壓成功后，把數據插入到數據庫 freemarkerService.save(freemarker);}else if (str.equals("rar")) { //開始解壓rar CompressFileUits.unRarFile(imageFile.getAbsolutePath(), descDir);freemarkerService.save(freemarker);} else if (str.equals("jpg") || str.equals("png") || str.equals("gif")) {/*** 增家java創建html功能，根據指定模板創建html*/freemarkerService.save(freemarker);//上傳的如果是圖片的話，就生成htmlString disrPath = ServletActionContext.getServletContext().getRealPath("template");String sourcedir = disrPath+"/template.html";//文件的http的路徑String IMAGEURL = httpURL+"/"+"template"+"/"+saveFileName+".html";//saveFileName 是文件的上傳的文件名稱 CreateHtmlUtils.MakeHtml(sourcedir, URL, disrPath, saveFileName);freemarkerDetailService.insertFreeMarkerDetailFile(orderNumber,saveFileName+".html",IMAGEURL,new Date());} else {throw new Exception("文件格式不正確不能解壓");}//遍歷文件夾 getFileList(descDir,orderNumber);return SUCCESS;}

2.然后是文件解壓的兩個類

package com.tydic.eshop.util;import java.io.File; import java.io.FileOutputStream; import java.io.IOException; import java.io.InputStream; import java.io.OutputStream; import java.util.Enumeration; import org.apache.tools.zip.ZipEntry; import org.apache.tools.zip.ZipFile;import com.github.junrar.Archive; import com.github.junrar.rarfile.FileHeader;public class CompressFileUits {/** * 解壓到指定目錄 * @param zipPath * @param descDir * @author*/ public static void unZipFiles(String zipPath,String descDir)throws IOException{ unZipFiles(new File(zipPath), descDir); } /** * 解壓文件到指定目錄 * @param zipFile * @param descDir * @author isea533 */ @SuppressWarnings("rawtypes") public static void unZipFiles(File zipFile,String descDir)throws IOException{ File pathFile = new File(descDir); if(!pathFile.exists()){ pathFile.mkdirs(); } ZipFile zip = new ZipFile(zipFile); for(Enumeration entries = zip.getEntries();entries.hasMoreElements();){ ZipEntry entry = (ZipEntry)entries.nextElement(); String zipEntryName = entry.getName(); InputStream in = zip.getInputStream(entry); String outPath = (descDir+zipEntryName).replaceAll("\\*", "/");; //判斷路徑是否存在,不存在則創建文件路徑 File file = new File(outPath.substring(0, outPath.lastIndexOf('/'))); if(!file.exists()){ file.mkdirs(); } //判斷文件全路徑是否為文件夾,如果是上面已經上傳,不需要解壓 if(new File(outPath).isDirectory()){ continue; } //輸出文件路徑信息 System.out.println(outPath); OutputStream out = new FileOutputStream(outPath); byte[] buf1 = new byte[1024]; int len; while((len=in.read(buf1))>0){ out.write(buf1,0,len); } in.close(); out.close(); } System.out.println("******************解壓完畢********************"); } /** * 根據原始rar路徑，解壓到指定文件夾下. * @param srcRarPath 原始rar路徑 * @param dstDirectoryPath 解壓到的文件夾 */public static void unRarFile(String srcRarPath, String dstDirectoryPath) {if (!srcRarPath.toLowerCase().endsWith(".rar")) {System.out.println("非rar文件！");return;}File dstDiretory = new File(dstDirectoryPath);if (!dstDiretory.exists()) {// 目標目錄不存在時，創建該文件夾 dstDiretory.mkdirs();}Archive a = null;try {a = new Archive(new File(srcRarPath));if (a != null) {a.getMainHeader().print(); // 打印文件信息.FileHeader fh = a.nextFileHeader();while (fh != null) {if (fh.isDirectory()) { // 文件夾 File fol = new File(dstDirectoryPath + File.separator+ fh.getFileNameString());fol.mkdirs();} else { // 文件File out = new File(dstDirectoryPath + File.separator+ fh.getFileNameString().trim());//System.out.println(out.getAbsolutePath());try {// 之所以這么寫try，是因為萬一這里面有了異常，不影響繼續解壓. if (!out.exists()) {if (!out.getParentFile().exists()) {// 相對路徑可能多級，可能需要創建父目錄. out.getParentFile().mkdirs();}out.createNewFile();}FileOutputStream os = new FileOutputStream(out);a.extractFile(fh, os);os.close();} catch (Exception ex) {ex.printStackTrace();}}fh = a.nextFileHeader();}a.close();}} catch (Exception e) {e.printStackTrace();}} }

3.常見html的工具類，上篇文章有介紹?CreateHtmlUtils

package com.tydic.eshop.util;import java.io.FileInputStream; import java.io.FileOutputStream; import java.util.Calendar;/*** @ClassName: CreateHtmlUtils * @Description: Java 根據模板創建 html* @author * @date 2016年4月22日 下午3:51:16*/ public class CreateHtmlUtils {public static void main(String[] args) {String filePath = "E:\\hh_web_space\\ecp\\web\\ecp_web_page\\src\\main\\webapp\\template\\template.html";String imagePath ="http://localhost:8080/ecp/upload/1461293787628/1461293787628.jpg";String disrPath = "E:\\hh_web_space\\ecp\\web\\ecp_web_page\\src\\main\\webapp\\template\\";String fileName = "liuren";MakeHtml(filePath,imagePath,disrPath,fileName);}/*** @Title: MakeHtml * @Description: 創建html* @param filePath 設定模板文件* @param imagePath 需要顯示圖片的路徑* @param disrPath 生成html的存放路徑* @param fileName 生成html名字 * @return void 返回類型 * @throws*/public static void MakeHtml(String filePath,String imagePath,String disrPath,String fileName ){try {String title = "<image src="+'"'+imagePath+'"'+"/>";System.out.print(filePath);String templateContent = "";FileInputStream fileinputstream = new FileInputStream(filePath);// 讀取模板文件int lenght = fileinputstream.available();byte bytes[] = new byte[lenght];fileinputstream.read(bytes);fileinputstream.close();templateContent = new String(bytes);System.out.print(templateContent);templateContent = templateContent.replaceAll("###title###", title);System.out.print(templateContent);String fileame = fileName + ".html";fileame = disrPath+"/" + fileame;// 生成的html文件保存路徑。FileOutputStream fileoutputstream = new FileOutputStream(fileame);// 建立文件輸出流System.out.print("文件輸出路徑:");System.out.print(fileame);byte tag_bytes[] = templateContent.getBytes();fileoutputstream.write(tag_bytes);fileoutputstream.close();} catch (Exception e) {System.out.print(e.toString());}}}

4.復制的方法 copy

// 復制方法public static void copy(File src, File dst) {try {InputStream in = null;OutputStream out = null;try {in = new BufferedInputStream(new FileInputStream(src),BUFFER_SIZE);out = new BufferedOutputStream(new FileOutputStream(dst),BUFFER_SIZE);byte[] buffer = new byte[BUFFER_SIZE];while (in.read(buffer) > 0) {out.write(buffer);}} finally {if (null != in) {in.close();}if (null != out) {out.close();}}} catch (Exception e) {e.printStackTrace();}}

5.便利解壓的的zip或者是rar文件夾

/*** @throws ServiceException * @Title: getFileList * @Description: 遞歸遍歷指定文件夾下的文件* @param @param strPath* @param @return 設定文件 * @return List<File> 返回類型 * @throws*/public List<File> getFileList(String strPath,String fileordernumber) throws ServiceException {File dir = new File(strPath);File[] files = dir.listFiles(); // 該文件目錄下文件全部放入數組List<File> fileList = new ArrayList<File>();if (files != null) {for (int i = 0; i < files.length; i++) {String fileName = files[i].getName();if (files[i].isDirectory()) { // 判斷是文件還是文件夾getFileList(files[i].getAbsolutePath(),fileordernumber); // 獲取文件絕對路徑System.out.println("輸出文件的絕對路徑"+files[i].getAbsolutePath());} else if (fileName.endsWith("html")) { // 判斷文件名是否以.avi結尾String strFileName = files[i].getAbsolutePath();System.out.println("------------" + strFileName+"+++++"+fileName); // uploadcompressDetailService.insertCompressDetailFile(fileordernumber,fileName,strFileName,new Date());freemarkerDetailService.insertFreeMarkerDetailFile(fileordernumber,fileName,strFileName,new Date());fileList.add(files[i]);} else {continue;}}}return fileList;}

?6.其中需要的架包

<!-- 導入zip解壓包 --><dependency><groupId>ant</groupId><artifactId>ant</artifactId><version>1.6.5</version></dependency><!-- 導入rar解壓包 --><dependency><groupId>com.github.junrar</groupId><artifactId>junrar</artifactId><version>0.7</version></dependency>
