我正在使用Spring 3.0.6.RELEASE和Primefaces 2.2.1做一个Web应用程序。在我的应用程序中有一个FileUpload组件。但是fileupload不工作。在backingbean FileUploadController中的upload()函数是从未打过电话。
我将这个包含在我的web.xml中:
<filter>
<filter-name>PrimeFaces FileUpload Filter</filter-name>
<filter-class>org.primefaces.webapp.filter.FileUploadFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>PrimeFaces FileUpload Filter</filter-name>
<servlet-name>Faces Servlet</servlet-name>
</filter-mapping>
在我的index.xhtml
中<p:dialog widgetVar="assetUploadDialog" modal="true" minHeight="300"
minWidth="550" closable="true" draggable="true"
closeOnEscape="true" header="Asset upload">
<h:form id="formuploader" >
<p:fileUpload id="fileuploader"
fileUploadListener="#{fileUploadController.upload}"
sizeLimit="100000"
allowTypes="*.jpg;*.gif;*.png;*.pdf;*.png;*.doc?x;*.xls;*.xlsx;"/>
</h:form>
</p:dialog>
在我的FileUploadController梁类中:
public class FileUploadController {
private String destination="D:\\";
public void upload(FileUploadEvent event) {
System.out.println("uplaod");
FacesMessage msg = new FacesMessage("Success! ", event.getFile().getFileName() + " is uploaded.");
FacesContext.getCurrentInstance().addMessage(null, msg);
try {
copyFile(event.getFile().getFileName(), event.getFile().getInputstream());
} catch (IOException e) {
e.printStackTrace();
}
}
public void copyFile(String fileName, InputStream in) {
try {
OutputStream out = new FileOutputStream(new File(destination + fileName));
int read = 0;
byte[] bytes = new byte[1024];
while ((read = in.read(bytes)) != -1) {
out.write(bytes, 0, read);
}
in.close();
out.flush();
out.close();
System.out.println("New file created!");
} catch (IOException e) {
System.out.println(e.getMessage());
}
}
}
我的问题的解决方案是什么?
