首先是webxml配置
<?xml version= encoding=ISO ?>
<!DOCTYPE webapp PUBLIC //Sun Microsystems Inc//DTD Web Application //EN app__dtd>
<webapp>
<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>
然后是strutsconfigxml
<?xml version= encoding=UTF?>
<!DOCTYPE strutsconfig PUBLIC //Apache Software Foundation//DTD Struts Configuration //EN config__dtd>
<strutsconfig>
<datasources />
<formbeans >
<formbean name=multiUploadForm type=comhbstrutsformMultiUploadForm />
</formbeans>
<globalexceptions />
<globalforwards />
<actionmappings >
<action
attribute=multiUploadForm
name=multiUploadForm
path=/multiUpload
scope=request
type=comhbstrutsactionMultiUploadAction
validate=false />
</actionmappings>
<messageresources parameter=comhbstrutsApplicationResources />
</strutsconfig>
然后是页面testjsp这段就是网上COPY的动态生成页面
<%@ 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 = 文件上传中;
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=++删除++ 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 = 文件上传完成<br> + msg;
}
</script>
<body bgcolor=#ffffff>
<div id=status></div>
<html:form method=post action=/multiUploaddo enctype=multipart/formdata target=hidden_frame>
<table id=tb>
</table>
</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
我把下面个文件放在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;
}
//注意这个方法的定义 不加中间的循环是会出错的
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;
}
}
最后是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 {
// 能运行到这里就可以使用单个文件上传的方法进行上传了循环而已
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;
}
}
这个是我从现在写好的里截取的一部分可能还是有不正确的地方但是大体的思想是在这了 struts 我用的jar包
