使用总结

/\*\*

\*要完成的功能，从页面上传zip文件及若干参数，将zip文件解压缩放到指定位置

\*使用到的组件有文件长传组件FileUpload，java类，java.util.zip;

接受页面的处理

DiskFileItemFactory dff = new DiskFileItemFactory();

dff.setSizeThreshold(Integer.parseInt(ZipUploadConfig.getProperty("SIZETHRESHOLD")));

ServletFileUpload sfu = new ServletFileUpload(dff);

sfu.setFileSizeMax(Integer.parseInt(ZipUploadConfig.getProperty("FILESIZEMAX")));

sfu.setSizeMax(Integer.parseInt(ZipUploadConfig.getProperty("SIZEMAX")));

HashMap param = new HashMap();

List list = sfu.parseRequest(request);//包括了，form表单中的字段和上传文件

if (list != null && list.size() > 0) \{

for (int i = 0; i < list.size(); i++) \{

FileItem fi = (FileItem) list.get(i);

if (fi.isFormField()) \{ //将参数中的form表单中的字段提取出来

String name = fi.getFieldName();

String value = fi.getString();

param.put(name, value);

String overload\_flag = ""+param.get("overload\_flag");//将form表单中的字段取出

String stylesheet = ""+param.get("stylesheet");

String template = ""+param.get("template");

if (list != null && list.size() > 0) \{

for (int j = 0; j < list.size(); j++) \{

FileItem fi = (FileItem) list.get(j);

if (!fi.isFormField() && fi.getName().length() > 0) \{ //将上传的文件取出

String zipFileName = fi.getName().substring(fi.getName().lastIndexOf("\\\\") + 1);//去掉盘符路径，只留下文件名

//contentInfo.setContenttype(zipFileName.substring(0, zipFileName.lastIndexOf(".")));

BufferedInputStream in = new BufferedInputStream(fi.getInputStream());

FileUploader zip = new FileUploader(db, in, contentInfo,servletContext);

Map result = zip.unzip();

in.close();

FileUploader.java

public FileUploader(DB db, InputStream inStream,ContentInfoBean contentInfo,ServletContext servletcontext) \{

super();

this.servletcontext = servletcontext;

this.inStream = inStream;

this.db = db;

this.contentInfo = contentInfo;

public HashMap unzip() \{

HashMap result = new HashMap();

// Expand ZIP file

ZipInputStream in = new ZipInputStream(this.inStream);

ZipEntry z;

Date now = new Date();

String tmpPath = UploadFileConfig.getUploadTmpPath() + File.separator + now.getTime();//UploadFileConfig.getUploadTmpPath()E:\\\\project\\\\V682\\\\upload\\\\tmp

File file = new File(tmpPath);

if (!file.exists()) \{

try \{

file.mkdirs(); //创建临时文件夹

\} catch (Exception e) \{

e.printStackTrace();

try \{

while ((z = in.getNextEntry()) != null) \{

String name = z.getName();

if (z.isDirectory()) \{

name = name.substring(0, name.length() - 1);

File f = new File(tmpPath + File.separator + name);

try \{

f.mkdirs();

\} catch (Exception e) \{

e.printStackTrace();

\} else \{

if (name.indexOf("/") > 0) \{

File folder = new File(tmpPath + File.separator + name.substring(0, name.lastIndexOf("/")));

if (!folder.exists()) \{

try \{

folder.mkdirs();

\} catch (Exception e) \{

e.printStackTrace();

File f = new File(tmpPath + File.separator + name);

f.createNewFile();

BufferedOutputStream out = new BufferedOutputStream(new FileOutputStream(f));

int size = 0;

byte\[\] b = new byte\[4096\];

while ((size = in.read(b)) != -1) \{

out.write(b, 0, size);

out.close();

\} catch (Exception e) \{

e.printStackTrace();
