Question

我尝试在JSP中添加注释以用于上传文件，而不是使用Servlet，以便我可以仅处理一个文件JSP中上传的文件。我遇到了一些问题，希望能得到您的建议。我非常感谢你我在web.xml中添加了多部分配置：

<servlet>
    <servlet-name>uploadfile</servlet-name>
    <jsp-file>/UploadFile.jsp</jsp-file>
    <multipart-config>
        <location>/tmp</location>
        <max-file-size>20848820</max-file-size>
        <max-request-size>418018841</max-request-size>
        <file-size-threshold>1048576</file-size-threshold>
    </multipart-config>
</servlet>
<servlet-mapping>
    <servlet-name>uploadfile</servlet-name>
    <url-pattern>/UploadFile.jsp</url-pattern>
</servlet-mapping>

但是当我运行UploadFile.jsp时，我收到了IOExeption

java.io.IOException: The temporary upload location [D:\Java\WorkSpace(ThuNghiem2)\.metadata\.plugins\org.eclipse.wst.server.core\tmp0\work\Catalina\localhost\Buoi32\tmp] is not valid

UploadFile.JSP中的内容是什么

<form method="POST" action=""  enctype="multipart/form-data">
    <input type="file" name="image" multiple /> //I just add 1 image per time for experiment
    <button type="submit" name="uploadclick">Upload</button>                
</form>

<%
if(request.getPart("image")!=null){
    Part p = request.getPart("image");
    ///// do ST
}else{
    ///// Do ST
}
%>
