1.本文只提供了一个功能的代码
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("--------获取登录用户信息:------------"+realName);/* 截取后缀名 */if (StringUtil.isEmpty(fileName)) {throw new Exception("文件不能为空");}int pos = fileName.lastIndexOf(".");String str = fileName.substring(pos+1).toLowerCase();//判断上传文件必须是zip或者是rar否则不允许上传if (StringUtil.isEmpty(str)||(!str.equals("zip")&&!str.equals("rar")&&!str.equals("png")&&!str.equals("jpg")&&!str.equals("gif"))) {throw new Exception("上传文件格式错误，请重新上传");}// 时间加后缀名保存saveName = new Date().getTime() + "."+str;//文件名saveFileName = saveName.substring(0, saveName.lastIndexOf("."));// 根据服务器的文件保存地址和原文件名创建目录文件全路径File imageFile = new File(ServletActionContext.getServletContext().getRealPath("upload")+ "/" +saveFileName+"/"+ saveName);File descFile = new File(ServletActionContext.getServletContext().getRealPath("upload")+"/"+saveFileName);if (!descFile.exists()) {descFile.mkdirs();}//解压目的文件String descDir = ServletActionContext.getServletContext().getRealPath("upload")+"/"+saveFileName+"/";copy(myFile, imageFile);//自己生成主键Long seqNo = freemarkerService.getOrderNumberSeq();String orderNumber = RandomIdGenerator.generatorOrderNumber(seqNo);HttpServletRequest httpRequest=(HttpServletRequest)request;String httpURL = "http://" + request.getServerName() //服务器地址 + ":" + request.getServerPort() //端口号 + httpRequest.getContextPath();//项目名称 String URL = httpURL+"/"+"upload"+"/"+saveFileName+"/"+saveName;System.out.println("============访问地址是：============="+ URL);//获取用户信息 freemarker.setFilesId(orderNumber);freemarker.setAuthor(realName);freemarker.setFilesName(saveFileName);freemarker.setFilesUrl(URL);//开始解压zipif (str.equals("zip")) {CompressFileUits.unZipFiles(imageFile, descDir);//文件解压成功后，把数据插入到数据库 freemarkerService.save(freemarker);}else if (str.equals("rar")) { //开始解压rar CompressFileUits.unRarFile(imageFile.getAbsolutePath(), descDir);freemarkerService.save(freemarker);} else if (str.equals("jpg") || str.equals("png") || str.equals("gif")) {/*** 增家java创建html功能，根据指定模板创建html*/freemarkerService.save(freemarker);//上传的如果是图片的话，就生成htmlString disrPath = ServletActionContext.getServletContext().getRealPath("template");String sourcedir = disrPath+"/template.html";//文件的http的路径String IMAGEURL = httpURL+"/"+"template"+"/"+saveFileName+".html";//saveFileName 是文件的上传的文件名称 CreateHtmlUtils.MakeHtml(sourcedir, URL, disrPath, saveFileName);freemarkerDetailService.insertFreeMarkerDetailFile(orderNumber,saveFileName+".html",IMAGEURL,new Date());} else {throw new Exception("文件格式不正确不能解压");}//遍历文件夹 getFileList(descDir,orderNumber);return SUCCESS;}
2.然后是文件解压的两个类
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 {/** * 解压到指定目录 * @param zipPath * @param descDir * @author*/ public static void unZipFiles(String zipPath,String descDir)throws IOException{ unZipFiles(new File(zipPath), descDir); } /** * 解压文件到指定目录 * @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("\\*", "/");; //判断路径是否存在,不存在则创建文件路径 File file = new File(outPath.substring(0, outPath.lastIndexOf('/'))); if(!file.exists()){ file.mkdirs(); } //判断文件全路径是否为文件夹,如果是上面已经上传,不需要解压 if(new File(outPath).isDirectory()){ continue; } //输出文件路径信息 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("******************解压完毕********************"); } /** * 根据原始rar路径，解压到指定文件夹下.* @param srcRarPath 原始rar路径 * @param dstDirectoryPath 解压到的文件夹*/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()) {// 目标目录不存在时，创建该文件夹 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()) { // 文件夹 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 {// 之所以这么写try，是因为万一这里面有了异常，不影响继续解压. if (!out.exists()) {if (!out.getParentFile().exists()) {// 相对路径可能多级，可能需要创建父目录. 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.常见html的工具类，上篇文章有介绍CreateHtmlUtils
package com.tydic.eshop.util;import java.io.FileInputStream;import java.io.FileOutputStream;import java.util.Calendar;/*** @ClassName: CreateHtmlUtils * @Description: Java 根据模板创建 html* @author * @date 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: 创建html* @param filePath 设定模板文件* @param imagePath 需要显示图片的路径* @param disrPath 生成html的存放路径* @param fileName 生成html名字 * @return void 返回类型 * @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);// 读取模板文件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文件保存路径。FileOutputStream fileoutputstream = new FileOutputStream(fileame);// 建立文件输出流System.out.print("文件输出路径:");System.out.print(fileame);byte tag_bytes[] = templateContent.getBytes();fileoutputstream.write(tag_bytes);fileoutputstream.close();} catch (Exception e) {System.out.print(e.toString());}}}
4.复制的方法 copy
// 复制方法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.便利解压的的zip或者是rar文件夹
/*** @throws ServiceException * @Title: getFileList * @Description: 递归遍历指定文件夹下的文件* @param @param strPath* @param @return 设定文件 * @return List<File> 返回类型 * @throws*/public List<File> getFileList(String strPath,String fileordernumber) throws ServiceException {File dir = new File(strPath);File[] files = dir.listFiles(); // 该文件目录下文件全部放入数组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()) { // 判断是文件还是文件夹getFileList(files[i].getAbsolutePath(),fileordernumber); // 获取文件绝对路径System.out.println("输出文件的绝对路径"+files[i].getAbsolutePath());} else if (fileName.endsWith("html")) { // 判断文件名是否以.avi结尾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
<!-- 导入zip解压包 --><dependency><groupId>ant</groupId><artifactId>ant</artifactId><version>1.6.5</version></dependency><!-- 导入rar解压包 --><dependency><groupId>com.github.junrar</groupId><artifactId>junrar</artifactId><version>0.7</version></dependency>
