JSP Java 上传文件问题与 io.common.

Question

我对common-io-2.4有一个问题，其中FileItemFactory似乎没有方法setReposity。我使用了Apache网站上的代码（Apache File Upload）。这相当令人愤怒，因为我看到其他人使用它没有任何问题。我已经将 jar 文件包含在我的项目中，并且库中的其他对象没有出现错误，只有那个。就好像它没有所有的方法。

有什么想法吗？这是我的代码，我用 Netbeans 编写它

import java.io.File;
import java.io.IOException;
import java.io.PrintWriter;
import java.util.List;
import javax.servlet.ServletContext;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.tomcat.util.http.fileupload.FileItem;
import org.apache.tomcat.util.http.fileupload.FileItemFactory;
import org.apache.tomcat.util.http.fileupload.FileUploadException;
import org.apache.tomcat.util.http.fileupload.disk.DiskFileItemFactory;
import org.apache.tomcat.util.http.fileupload.servlet.ServletFileUpload;

    /**

    protected void processRequest(HttpServletRequest request, HttpServletResponse response)
            throws ServletException, IOException {
        response.setContentType("text/html;charset=UTF-8");
        PrintWriter out = response.getWriter();
        
        if(ServletFileUpload.isMultipartContent(request)){ // checks if it is an upload request;
            // Create a factory for disk-based file items
            FileItemFactory factory = new DiskFileItemFactory();
            
            // Configure a repository (to ensure a secure temp location is used)
            ServletContext servletContext = this.getServletConfig().getServletContext();
            File repository = (File) servletContext.getAttribute("javax.servlet.context.tempdir");
            factory.setReposity(repository);
           
            // Create a new file upload handler
            ServletFileUpload upload = new ServletFileUpload(factory);
            try{
                // Parse the request
               List<FileItem> items = upload.parseRequest(request);  // this creates fileItems, which i then need to loop through and write each one to the file. 
               
               
            }catch(FileUploadException ex){
                System.out.println("Failed to upload file");
            }
            
            
        }
        else{
            response.sendRedirect("UserHome.jsp");
        }
        
    }

此对象

文件项工厂

似乎没有方法setReposity或许多其他方法。我不知道为什么？

也许我只是错过了一些简单的东西？任何帮助都会很棒！干杯！

发现该示例使用了 FileItemFactory，但发现如果将其切换到 DiskFileItemFactory，则可以访问这些方法。
