基於Struts1.2的動態多文件上傳

　　首先是webxml配置

　　<?xml version= encoding=ISO ?>
<!DOCTYPE webapp PUBLIC //Sun Microsystems Inc//DTD Web Application //EN app__dtd>

　　<servlet>
               <servletname>action</servletname>
               <servletclass>orgapachestrutsactionActionServlet</servletclass>
                   <initparam>
                     <paramname>config</paramname>
                     <paramvalue>/WEBINF/strutsconfigxml</paramvalue>
                   </initparam>
               <loadonstartup></loadonstartup>
           </servlet>

　　<servletmapping>
               <servletname>action</servletname>
               <urlpattern>*do</urlpattern>
         </servletmapping>

　　</webapp>
然後是strutsconfigxml

　　<?xml version= encoding=UTF?>
<!DOCTYPE strutsconfig PUBLIC //Apache Software Foundation//DTD Struts Configuration //EN config__dtd>

　　</actionmappings>
<messageresources parameter=comhbstrutsApplicationResources />
</strutsconfig>

　　然後是頁面testjsp這段就是網上COPY的動態生成頁面

　　<%@ page language=java pageEncoding=utf%>

　　<%@ taglib uri=bean prefix=bean %>
    <%@ taglib uri=html prefix=html %>
    <%@ taglib uri=logic prefix=logic %>
    <%@ taglib uri=tiles prefix=tiles %>

　　<!DOCTYPE HTML PUBLIC //WC//DTD HTML Transitional//EN>
    <html:html>
    <head>
    <title>
    multiUploadDemo
    </title>

　　<script language=javascript>
var num = ;

　　function upload(){
      documentgetElementById(status)innerHTML = 文件上傳中;
         multiUploadFormsubmit();
       }

　　function additem(id)
{
var rowcellstr;

　　row = eval(documentall[++id++])insertRow();
     if(row != null )
        {
           cell = rowinsertCell();
           str=<input type=++file++ name=uploadFile[+ num +]file><input type=++button++ value=++刪除++ onclick=deleteitem(this++tb++);>
          cellinnerHTML=str;
        }
     num++;
    }
    function deleteitem(objid)
    {
     var rowNumcurRow;
     curRow = objparentNodeparentNode;
     rowNum = eval(documentall+id)rowslength ;
     eval(documentall[++id++])deleteRow(curRowrowIndex);
    }
    function callback(msg)
    {
     documentgetElementById(status)innerHTML = 文件上傳完成<br> + msg;
    }
    </script>
    <body bgcolor=#ffffff>
    <div id=status></div>
    <html:form method=post action=/multiUploaddo enctype=multipart/formdata target=hidden_frame>

　　</html:form>
    <iframe name=hidden_frame id=hidden_frame ></iframe>
    <input type=button name=btnAddFile value=Add File onclick=additem(tb)/>
    <input type=button name=btnUpload value=upload onclick=upload()/>
    </body>
    </html:html>

　　下面是FORM和ACTION

我把下面個文件放在FORM包中

　　UploadFile java

　　package comhbstrutsform;
import javaioSerializable;

　　import orgapachestrutsuploadFormFile;

　　public class UploadFile implements Serializable {
      private FormFile file;
         public FormFile getFile() {
                 Systemoutprintln(run in uploadFilegetFile());
                 return file;
         }
         public void setFile(FormFile file) {
                 thisfile = file;
         }
    }

　　MultiUploadForm java

　　package comhbstrutsform;
import javautilArrayList;
import javautilList;

　　import orgapachestrutsactionActionForm;

　　import comhbstrutsUploadFile;

　　public class MultiUploadForm extends ActionForm {
private List myFiles;

　　public MultiUploadForm(){
                myFiles = new ArrayList();
                myFilesadd(new UploadFile());
        }
        public List getMyFiles() {
                return myFiles;
        }

　　//注意這個方法的定義不加中間的循環是會出錯的

　　public UploadFile getUploadFile(int index){
                int size = myFilessize();
                if(index>size){
                 for(int i=;i<indexsize+;i++){
                        myFilesadd(new UploadFile());
                 }
                }
                return (UploadFile)myFilesget(index);
        }
        public void setMyFiles(List myFiles) {
                thismyFiles = myFiles;
        }

　　}

　　最後是action

　　package comhbstrutsaction;

　　import javaioIOException;
import javaioPrintWriter;
import javautilList;

　　import javaxservlethttpHttpServletRequest;
import javaxservlethttpHttpServletResponse;

　　import orgapachestrutsactionAction;
    import orgapachestrutsactionActionForm;
    import orgapachestrutsactionActionForward;
    import orgapachestrutsactionActionMapping;
    import orgapachestrutsuploadFormFile;

　　public class MultiUploadAction extends Action {
     public ActionForward execute(ActionMapping mapping ActionForm form
       HttpServletRequest request HttpServletResponse response) {
      MultiUploadForm multiUploadForm = (MultiUploadForm) form;

　　List myFiles = multiUploadFormgetMyFiles();
      String fileStr = ;
      for (int i = ; i < myFilessize(); i++) {
       UploadFile uploadFile = (UploadFile) myFilesget(i);
       FormFile file = uploadFilegetFile();

　　if (file == null) {
Systemoutprintln(file is null);
} else {

　　// 能運行到這裡就可以使用單個文件上傳的方法進行上傳了循環而已
        Systemoutprintln(filename>>>>>>>>>> + filegetFileName());
        Systemoutprintln(file size>>>>>>>>>> + filegetFileSize());
        fileStr += filename::: + filegetFileName() + file size:::
          + filegetFileSize();

　　}
      }
// 返回文本
      try {
       responsesetHeader(ContentType text/html;charset=gbk);
       PrintWriter out = responsegetWriter();
       outwrite(<script>parentcallback(upload file success + fileStr
         + )</script>);
      } catch (IOException e) {
       eprintStackTrace();
      }

　　return null;
}

　　}

　　這個是我從現在寫好的裡截取的一部分可能還是有不正確的地方但是大體的思想是在這了 struts 我用的jar包
