jsp的上傳與下載
㈠ 在jsp中怎麼上傳文件和下載文件啊
查查這個：SmartUpload
實現上傳下載 非常方便
㈡ jsp怎麼下載上傳文件
去apache網站上下個common-fileupload上傳組件用就可以了！
㈢ jsp+servlet實現文件上傳與下載源碼
上傳：
需要導入兩個包：commons-fileupload-1.2.1.jar,commons-io-1.4.jar
import java.io.File;
import java.io.IOException;
import java.util.List;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.commons.fileupload.FileItem;
import org.apache.commons.fileupload.disk.DiskFileItemFactory;
import org.apache.commons.fileupload.servlet.ServletFileUpload;
/**
* 上傳附件
* @author new
*
*/
public class UploadAnnexServlet extends HttpServlet {
private static String path = "";
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
doPost(request, response);
}
/*
* post處理
* (non-Javadoc)
* @see javax.servlet.http.HttpServlet#doPost(javax.servlet.http.HttpServletRequest, javax.servlet.http.HttpServletResponse)
*/
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
path = this.getServletContext().getRealPath("/upload");
try {
DiskFileItemFactory factory = new DiskFileItemFactory();
ServletFileUpload up = new ServletFileUpload(factory);
List<FileItem> ls = up.parseRequest(request);
for (FileItem fileItem : ls) {
if (fileItem.isFormField()) {
String FieldName = fileItem.getFieldName();
//getName()返回的是文件名字 普通域沒有文件 返回NULL
// String Name = fileItem.getName();
String Content = fileItem.getString("gbk");
request.setAttribute(FieldName, Content);
} else {
String nm = fileItem.getName().substring(
fileItem.getName().lastIndexOf("\\") + 1);
File mkr = new File(path, nm);
if (mkr.createNewFile()) {
fileItem.write(mkr);//非常方便的方法
}
request.setAttribute("result", "上傳文件成功！");
}
}
} catch (Exception e) {
e.printStackTrace();
request.setAttribute("result", "上傳失敗，請查找原因，重新再試！");
}
request.getRequestDispatcher("/pages/admin/annex-manager.jsp").forward(
request, response);
}
}
下載（i/o流）無需導包：
import java.io.IOException;
import java.net.URLEncoder;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
/**

private static final long serialVersionUID = 8594448765428224944L;
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
doPost(request, response);
}
/*
* 處理請求
* (non-Javadoc)
* @see javax.servlet.http.HttpServlet#doPost(javax.servlet.http.HttpServletRequest, javax.servlet.http.HttpServletResponse)
*/
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
String name = request.getParameter("fileName");
System.out.print("dddddddddd:" + name);
// web絕對路徑
String path = request.getSession().getServletContext().getRealPath("/");
String savePath = path + "upload";
// 設置為下載application/x-download
response.setContentType("application/x-download");
// 即將下載的文件在伺服器上的絕對路徑
String filenamedownload = savePath + "/" + name;
// 下載文件時顯示的文件保存名稱
String filenamedisplay = name;
// 中文編碼轉換
filenamedisplay = URLEncoder.encode(filenamedisplay, "UTF-8");
response.addHeader("Content-Disposition", "attachment;filename="
+ filenamedisplay);
try {
java.io.OutputStream os = response.getOutputStream();
java.io.FileInputStream fis = new java.io.FileInputStream(
filenamedownload);
byte[] b = new byte[1024];
int i = 0;
while ((i = fis.read(b)) > 0) {
os.write(b, 0, i);
}
fis.close();
os.flush();
os.close();
} catch (Exception e) {
}
}
}
㈣ jsp 文件的上傳與下載 要求對文件的類型、大小進行選擇判斷
你下載一個 jspsmartupload 里不是有七個例子，其中一個就是了，你看看
㈤ jsp 如何實現文件上傳和下載功能
上傳：
MyjspForm mf = (MyjspForm) form;// TODO Auto-generated method stub
FormFile fname=mf.getFname();
byte [] fn = fname.getFileData();
OutputStream out = new FileOutputStream("D:\"+fname.getFileName());
Date date = new Date();
String title = fname.getFileName();
String url = "d:\"+fname.getFileName();
Upload ul = new Upload();
ul.setDate(date);
ul.setTitle(title);
ul.setUrl(url);
UploadDAO uld = new UploadDAO();
uld.save(ul);
out.write(fn);
out.close();
下載：
DownloadForm downloadForm = (DownloadForm)form;
String fname = request.getParameter("furl");
FileInputStream fi = new FileInputStream(fname);
byte[] bt = new byte[fi.available()];
fi.read(bt);
//設置文件是下載還是打開以及打開的方式msdownload表示下載；設置字湖集，//主要是解決文件中的中文信息
response.setContentType("application/msdownload;charset=gbk");
//文件下載後的默認保存名及打開方式
String contentDisposition = "attachment; filename=" + "java.txt";
response.setHeader("Content-Disposition",contentDisposition);
//設置下載長度
response.setContentLength(bt.length);
ServletOutputStream sos = response.getOutputStream();
sos.write(bt);
return null;
㈥ jsp如何實現文件上傳與下載
如果伺服器端程序使用的是struts2框架的話，我會，其他的不會。
struts2：
對於上傳，jsp頁面只需要有個file類型的表單域，如<input type="file" name="xxx" />
struts2的接收請求的action中再寫三個屬性與這個表單域的名稱對應起來，他們是，File類型的xxx,String類型的xxxFileName,String類型的xxxContentType，並其設置相應的set/get方法。則框架負責接收上傳文件的位元組流，解析文件名，文件類型，直接使用即可。
對於下載，只需要在action的配置文件中設置如下返回值類型和相應參數：
<result type="stream">
<param name="contentType">application/octet-stream</param>
<param name="inputName">inputStream</param>
<param name="contentDisposition">attachment;filename=xxx </param> xxx為下載文件的文件名
</result>
且在action總寫一個返回值類型為InputStream的getInputStream方法，此方法返回你要下載的文件的流即可。
ps:其中contentDisposition的配置信息中attachment代表點擊下載時瀏覽器先彈出個保存位置的提示框，然後再決定是否下載，默認是inline，即直接打開文件。

㈧ 請問誰會文件的上傳和下載啊，基於jsp的，直接右擊連接，另存為的那種
要用到jspSmartUpload組件，先到www.jspsmart.com網站下載這個組件（或直接搜它），下載解壓後，把Web-inf/classes下的文件打成JAR包，放到Tomcat的，lib下，再在你的項目中導入此JAR包。
下面附代碼給你，去試試：

㈨ jsp上傳文件的問題
用JSP實現文件上傳功能，參考如下：
UploadExample.jsp
<%@ page contentType="text/html;charset=gb2312"%>
<html>
<title><%= application.getServerInfo() %></title>
<body>
上傳文件程序應用示例
<form action="doUpload.jsp" method="post" enctype="multipart/form-data">
<%-- 類型enctype用multipart/form-data，這樣可以把文件中的數據作為流式數據上傳，不管是什麼文件類型，均可上傳。--%>
請選擇要上傳的文件<input type="file" name="upfile" size="50">
<input type="submit" value="提交">
</form>
</body>
</html>
doUpload.jsp
<%@ page contentType="text/html; charset=GBK" %>

㈩ jsp上傳下載文件的路徑問題
jsp上傳下載文件的路徑是在伺服器建立指定路徑如下：
//接收上傳文件內容中臨時文件的文件名
String tempFileName = new String("tempFileName");
//tempfile 對象指向臨時文件
File tempFile = new File("D:/"+tempFileName);
//outputfile 文件輸出流指向這個臨時文件
FileOutputStream outputStream = new FileOutputStream(tempFile);
//得到客服端提交的所有數據
InputStream fileSourcel = request.getInputStream();
//將得到的客服端數據寫入臨時文件
byte b[] = new byte[1000];
int n ;
while ((n=fileSourcel.read(b))!=-1){
outputStream.write(b,0,n);
}
//關閉輸出流和輸入流
outputStream.close();
fileSourcel.close();
//randomFile對象指向臨時文件
RandomAccessFile randomFile = new RandomAccessFile(tempFile,"r");
//讀取臨時文件的第一行數據
randomFile.readLine();
//讀取臨時文件的第二行數據，這行數據中包含了文件的路徑和文件名
String filePath = randomFile.readLine();
//得到文件名
int position = filePath.lastIndexOf('\\');
CodeToString codeToString = new CodeToString();
String filename = codeToString.codeString(filePath.substring(position,filePath.length()-1));
//重新定位讀取文件指針到文件頭
randomFile.seek(0);
//得到第四行回車符的位置，這是上傳文件數據的開始位置
long forthEnterPosition = 0;
int forth = 1;
while((n=randomFile.readByte())!=-1&&(forth<=4)){
if(n=='\n'){
forthEnterPosition = randomFile.getFilePointer();
forth++;
}
}
//生成上傳文件的目錄
File fileupLoad = new File("D:/work space/JSP workspace/jsp_servlet_upAndLoad/file","upLoad");
fileupLoad.mkdir();
//saveFile 對象指向要保存的文件
File saveFile = new File("D:/work space/JSP workspace/jsp_servlet_upAndLoad/file/upLoad",filename);
RandomAccessFile randomAccessFile = new RandomAccessFile(saveFile,"rw");
//找到上傳文件數據的結束位置，即倒數第四行
randomFile.seek(randomFile.length());
long endPosition = randomFile.getFilePointer();
int j = 1;
while((endPosition>=0)&&(j<=4)){
endPosition--;
randomFile.seek(endPosition);
if(randomFile.readByte()=='\n'){
j++;
}
}
//從上傳文件數據的開始位置到結束位置，把數據寫入到要保存的文件中
randomFile.seek(forthEnterPosition);
long startPoint = randomFile.getFilePointer();
while(startPoint<endPosition){
randomAccessFile.write(randomFile.readByte());
startPoint = randomFile.getFilePointer();
}
//關閉文件輸入、輸出
randomAccessFile.close();
randomFile.close();
tempFile.delete();
jsp文件下載選擇路徑：
//要下載的文件
File fileload = new File("D:/work space/JSP workspace/jsp_servlet_upAndLoad/file/upLoad",filename);
