package com.jsp.servlet;

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 javax.swing.text.AbstractDocument.Content;

import org.apache.commons.fileupload.FileItem;
import org.apache.commons.fileupload.disk.DiskFileItemFactory;
import org.apache.commons.fileupload.servlet.ServletFileUpload;

import com.jsp.model.Upload;
import com.jsp.service.UploadService;
public class UploadServlet extends HttpServlet{
private static String path="";
@Override
protected void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
}

@Override
protected void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
path=this.getServletContext().getRealPath("/work");
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();
String Content= fileItem.getString("utf-8");
request.setAttribute(FieldName,Content);
String title = request.getParameter("title");
String notes = request.getParameter("textarea");
String state = request.getParameter("state");
Upload upload=new Upload();
upload.setTitle(title);
upload.setImagesname(FieldName);
upload.setNotes(notes);
upload.setState(state);
//调用UploadService完成用户上传作品的业务逻辑
UploadService service = new UploadService();
service.upload(upload);
}else{
String nm=fileItem.getName().substring(fileItem.getName().lastIndexOf("\\")+1);
File mkr=new File(path,nm);
if(mkr.createNewFile()){
fileItem.write(mkr);
}
request.setAttribute("result","上传文件成功!");
}
}
}
catch(Exception e){
e.printStackTrace();
request.setAttribute("result","上传失败，请查找原因，重新再试！");
}
request.getRequestDispatcher("/works_exhibition.jsp").forward(request, response);
}
}
