我正在使用带有primefaces的jsf2.0 ..在我的应用程序中，我有图像上传选项。文件上传工作正常除了IE9以外的所有浏览器..当我尝试在IE9上传文件时我没有上传，我收到以下错误。
堆栈跟踪

我的image.xhtml是
<f:view>
<h:form enctype="multipart/form-data">
<p:panel header="Event Images" style="font-size:12px;height:499px">
<h:inputHidden value="#{photoUploadAction.aid}"></h:inputHidden>
<p:messages id="messages" for="imaload"></p:messages>
<p:fileUpload id="imaload" fileUploadListener="#{photoUploadAction.handleImage}"
mode="advanced" multiple="true"
update="messages"
immediate="true"
allowTypes="/(\.|\/)(gif|jpe?g|png)$/"/>
<!-- <p:growl life="1000" id="messages"/> -->
</p:panel>
</h:form>
</f:view>
我的支持bean方法是
public void handleImage(FileUploadEvent event) throws IOException {
BufferedImage bufferedImage;
// setAid(getAid());
String tmpFile = scontext.getRealPath(("/activityPhoto/")
+ event.getFile().getFileName());
//File realPath = new File("e:/cv_project/ChennaiVolunteer/WebContent/activityPhoto",(event.getFile().getFileName()));
File realPath = new File("d:/Program Files (x86)/Apache Software Foundation/Tomcat 7.0/webapps/ChennaiVolunteer/activityPhoto",(event.getFile().getFileName()));
String filName = realPath.toString();
/*File result = new File(tmpFile);
String exactPath = result.toString();
*/
byte[] imageByte = event.getFile().getContents();
boolean flag = false;
//storeImage(imageByte, tmpFile);
String images = event.getFile().getFileName();
photoUploadVO.setImageName(images);
imageName = photoUploadVO.getImageName();
if (loginBean.getType().equals("admin")
|| loginBean.getType().equals("ngo_coordinator")
|| loginBean.getType().equals("ngo")) {
if (ngoPojo.getNgo_id() != 0) {
photoUploadVO.setUsrId(ngoPojo.getNgo_id());
photoUploadVO.setPhotoStatus("valid");
photoUploadVO.setReasonForReject("pending");
photoUploadVO.setUser_type(ngoPojo.getType());
} else {
photoUploadVO.setUsrId(loginBean.getUser_id());
photoUploadVO.setPhotoStatus("valid");
photoUploadVO.setReasonForReject("pending");
photoUploadVO.setUser_type(loginBean.getType());
}
} else {
photoUploadVO.setUsrId(loginBean.getUser_id());
photoUploadVO.setPhotoStatus("pending");
photoUploadVO.setReasonForReject("pending");
photoUploadVO.setUser_type(loginBean.getType());
}
photoUploadVO.setCreated_by(loginBean.getEmail());
photoUploadVO.setCreatedDate(new Date());
photoUploadVO.setPhoto_path(tmpFile);
InputStream in = new ByteArrayInputStream(imageByte);
// photoUploadVO.setUsrId(loginBean.getUser_id());
// photoUploadVO.setActivityId(getAid());
bufferedImage = ImageIO.read(in);
if (bufferedImage.getWidth() <= 400 && bufferedImage.getHeight() <= 400) {
photoUploadVO.setDisabled("false");
getMthd(imageByte, tmpFile);
} else {
try {
photoUploadVO.setDisabled("false");
//BufferedImage image = ImageIO.read(in);
ImageIO.write(resize(bufferedImage, 400, 400), "jpg", new File(tmpFile));
flag = photoUploadDaoService.uploadPhotos(photoUploadVO);
// profileImageService.uploadPhotos(profileImageBean);
if (flag == true) {
FacesMessage msg=null;
if(loginBean.getType().equals("admin")) {
msg = new FacesMessage("Successfully Uploaded");
}
if(!loginBean.getType().equals("admin")) {
msg = new FacesMessage("Successfully Uploaded(After administrator approve your photos will display on portal)");
}
FacesContext.getCurrentInstance().addMessage(null, msg);
} else {
FacesMessage msg = new FacesMessage("Failure", event
.getFile().getFileName() + " to uploaded.");
FacesContext.getCurrentInstance().addMessage(null, msg);
}
} catch (IOException e) {
e.printStackTrace();
FacesMessage error = new FacesMessage(
FacesMessage.SEVERITY_ERROR,
"The files were not uploaded!", "");
FacesContext.getCurrentInstance().addMessage(null, error);
}
}
}
提前致谢。
答案 0 :(得分：3)
这是由IE中的安全漏洞引起的。所有IE版本都发送完整的客户端文件路径，而不仅仅是文件名和上传文件。
您应该使用Commons IO FilenameUtils#getName()从完整的客户端文件路径中提取文件名，然后再在代码中使用它。
String filename = FilenameUtils.getName(event.getFile().getFileName()));
// ...
FileItem.getName() return the whole path, and not just the file name? 无关，整个tmpFile变量是多余的。到目前为止，您在代码中根本不需要它。完全摆脱它。这也是创建临时文件的错误方法。 getRealPath()可能会在某些服务器配置中返回null，并且绝对不想保存文件，只能从中读取文件。
