先上图
在一个form里面实现两个文件的不同时上传,两个上传互不干涉.
之前只有一个file 和submit,即Select Excel File那一行;现在我加上了下面的Feedback File 一行file和submit.
结果导致只能Feedback这个submit能够上传文件,Select那一行的submit一上传就出错,说是The input file was not found.
然后我后台输出Select一行的file.getFileName()为空.这是为什么呢!
上代码
这是form体
<html:form action="uploadAction.do?method=upFile"
enctype="multipart/form-data">
<c:choose>
<c:when test="${zn == 'pilot'}">
<input type="radio" name="name" value="pilot"
checked="checked" onclick="getZoneDate('pilot');"/>
<font color="red">PRFQ1</font>
</c:when>
<c:otherwise>
<input type="radio" name="name" value="pilot" onclick="getZoneDate('pilot');"/>
<font color="red">PRFQ1</font>
</c:otherwise>
</c:choose>
<c:choose>
<c:when test="${zn == 'week'}">
<input type="radio" name="name" value="week"
checked="checked" onclick="getZoneDate('week');"/>
<font color="red">PRFQ2</font>
</c:when>
<c:otherwise>
<input type="radio" name="name" value="week" onclick="getZoneDate('week');"/>
<font color="red">PRFQ2</font>
</c:otherwise>
</c:choose>
<br/>
Select Excel File:<html:file property="theFile" />
<html:submit value="upload"/>
<br/>
FeedBack File:<html:file property="theFile" />
<html:submit value="upload" onclick="this.form.action='uploadAction.do?method=upFBFile'"/>
</html:form>
这是后台action过程
Select一行的submit
public ActionForward upFile(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response)
throws Exception {
String filePathName = "";
if (form instanceof UploadForm) {
String encoding = request.getCharacterEncoding();
if ((encoding != null) && (encoding.equalsIgnoreCase("utf-8"))) {
response.setContentType("text/html; charset=gb2312");
}
UploadForm theForm = (UploadForm) form;
FormFile file = theForm.getTheFile();
String contentType = file.getContentType();
String zoneName = theForm.getName();
String size = (file.getFileSize() + " bytes");
String fileName = file.getFileName();
//
System.out.println("fileName="+fileName); //这里打印为"fileName=",明显没有值
String timeStr = df.getTime("yyyyMMddhhmmss");
try {
InputStream stream = file.getInputStream();
String filePath = request.getRealPath("/");
ByteArrayOutputStream baos = new ByteArrayOutputStream();
OutputStream bos = null;
filePathName = filePath+ "files" + "\\"+ timeStr+file.getFileName();
String pathName = request.getSession().getServletContext().getRealPath("/") + "files";
File files= new File(pathName);
if(files.exists()&&files.isDirectory()){
bos = new FileOutputStream(filePath + "files"+ "\\"
+ timeStr+file.getFileName());
int bytesRead = 0;
byte[] buffer = new byte[8192];
while ((bytesRead = stream.read(buffer, 0, 8192)) != -1) {
bos.write(buffer, 0, bytesRead);
}
}else{
boolean flag = files.mkdir();
if(flag){
bos = new FileOutputStream(filePath + "files"+ "\\"
+ timeStr+file.getFileName());
int bytesRead = 0;
byte[] buffer = new byte[8192];
while ((bytesRead = stream.read(buffer, 0, 8192)) != -1) {
bos.write(buffer, 0, bytesRead);
}
}
}
bos.close();
stream.close();
} catch (Exception e) {
}
request.setAttribute("contentType", contentType);
request.setAttribute("size", size);
request.setAttribute("fileName", fileName);
request.setAttribute("filePathName", filePathName);
request.setAttribute("zoneName", zoneName);
return mapping.findForward("display");
}
return null;
}
Feedback一行的submit
public ActionForward upFBFile(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response)
throws Exception {
String filePathName = "";
if (form instanceof UploadForm) {
String encoding = request.getCharacterEncoding();
if ((encoding != null) && (encoding.equalsIgnoreCase("utf-8"))) {
response.setContentType("text/html; charset=gb2312");
}
UploadForm theForm = (UploadForm) form;
FormFile file = theForm.getTheFile();
String contentType = file.getContentType();
String zoneName = theForm.getName();
String size = (file.getFileSize() + " bytes");
String fileName = file.getFileName();
String timeStr = df.getTime("yyyyMMddhhmmss");
try {
InputStream stream = file.getInputStream();
String filePath = request.getRealPath("/");
ByteArrayOutputStream baos = new ByteArrayOutputStream();
OutputStream bos = null;
filePathName = filePath+ "files" + "\\"+ timeStr+file.getFileName();
String pathName = request.getSession().getServletContext().getRealPath("/") + "files";
File files= new File(pathName);
if(files.exists()&&files.isDirectory()){
bos = new FileOutputStream(filePath + "files"+ "\\"
+ timeStr+file.getFileName());
int bytesRead = 0;
byte[] buffer = new byte[8192];
while ((bytesRead = stream.read(buffer, 0, 8192)) != -1) {
bos.write(buffer, 0, bytesRead);
}
}else{
boolean flag = files.mkdir();
if(flag){
bos = new FileOutputStream(filePath + "files"+ "\\"
+ timeStr+file.getFileName());
int bytesRead = 0;
byte[] buffer = new byte[8192];
while ((bytesRead = stream.read(buffer, 0, 8192)) != -1) {
bos.write(buffer, 0, bytesRead);
}
}
}
bos.close();
stream.close();
} catch (Exception e) {
}
request.setAttribute("contentType", contentType);
request.setAttribute("size", size);
request.setAttribute("fileName", fileName);
request.setAttribute("filePathName", filePathName);
request.setAttribute("zoneName", zoneName);
return mapping.findForward("displayFB");
}
return null;
}
这俩代码几乎似乎一样的,为什么会导致这样呢!
