jspSmartUpload组件总结

1.    使用这个组件，form中要添加 enctype="multipart/form-data"
   这样获取表单其他元素要用mySmartUpload.getRequest().getParameter("name"); 获取，并且必须放在save path之后，否则是null
2. 前台jsp上传代码：jspSmartUpload组件测试

    <form action="./user/upload.jsp" method="post" enctype="multipart/form-data"> <input type="file" name="myfile"><br> <input type="text" name="test"><br> <input type="submit" value="上传"> </form>

 

    3.  jsp处理页面：

     <% SmartUpload su = new SmartUpload();su.initialize(pageContext);su.upload();int count = su.save("./upload");//获取表单数据，一定要放在save path之后，否则是nullout.println("test:"+su.getRequest().getParameter("test")); out.println("成功上传"+count+"个文件");for(int i = 0; i < su.getFiles().getCount(); i++){com.jspsmart.upload.File file = su.getFiles().getFile(i);if(file.isMissing())continue;out.println(file.getFieldName());} %>

    4.用serlvet处理：

    

类似下面代码，主要是改下form中的action转到这个servlet就可以。import java.io.*;import java.util.*;import javax.servlet.*;import javax.servlet.http.*;import com.jspsmart.upload.*;import FenBean.Fen;public class doservlet extends HttpServlet {private ServletConfig config;//初始化Servletfinal public void init(ServletConfig config) throws ServletException {this.config = config;}//处理GET请求public void doGet(HttpServletRequest request,HttpServletResponse response) throws ServletException, IOException {PrintWriter out = response.getWriter();out.println("The method of the HTML form must be POST.");}//响应POST请求protected void doPost(HttpServletRequest request,HttpServletResponse response) throws ServletException, IOException {response.setContentType("text/html;charset=GBK");PrintWriter out = response.getWriter();request.setCharacterEncoding("GBK");// 变量定义int count=0;String path=request.getRealPath("/");String num="1";String filename=null;SmartUpload mySmartUpload = new SmartUpload(); // 初始化mySmartUpload.initialize(config,request,response);filename=mySmartUpload.getRequest().getParameter("sourcefile");num= mySmartUpload.getRequest().getParameter("num");out.println(filename+""+num+"");try {// 上载mySmartUpload.upload();filename=mySmartUpload.getFiles().getFile(0).getFileName();// 保存上载文件到指定目录// PATH为form表单提交过来的count = mySmartUpload.save(path);// 显示处理结果out.println(count + "文件已上传至："+path+"");} catch (Exception e){out.println("Unable to upload the file.");out.println("Error : " + e.toString());}out.println(num+""+filename+"");//Fen myfileFen=new Fen();//myfileFen.cut(path+filename,num); }}

5. 用struts中的action处理

代码如下：public ActionForward execute(ActionMapping mapping, ActionForm form,HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException, SmartUploadException {// TODO Auto-generated method stubSmartUpload su = new SmartUpload();su.initialize(this.getServlet().getServletConfig(),request,response);su.upload();int count = su.save("./upload");System.out.println("成功上传"+count+"个文件");for(int i = 0; i < su.getFiles().getCount(); i++){com.jspsmart.upload.File file = su.getFiles().getFile(i);if(file.isMissing())continue;System.out.println(file.getFieldName());}return null;}

6.总结：
1）主要是在form中添加enctype="multipart/form-data"属性，以及获取表单其他元素值用mySmartUpload.getRequest().getParameter("name"); 获取，并且必须放在save path之后，否则是null

2）jsp中，初始化用SmartUpload su = new SmartUpload();
  su.initialize(pageContext);
