Question

我必须上传文件并将文件名，文件保存在系统中的路径和文件类型（.pdf，.txt等）保存到oracle数据库中。我已经完成了文件上传路径，还编写了用于保存在数据库中的代码，但是值没有保存在数据库中。我是struts2的新手，所以请任何人都可以提供帮助..

的index.jsp：

<%@ taglib prefix="s" uri="/struts-tags" %>
<html>
<head>
<s:head />
</head>

<s:actionerror />

<s:form action="uploadAction" method="POST" enctype="multipart/form-data">
   <s:file name="uploadFile" label="Choose File" size="40" />
   <s:submit value="Upload" name="submit" />
</s:form>

的success.jsp

<%@ taglib prefix="s" uri="/struts-tags" %>
<html>
 <body>
   File uploaded successfully...!!!

   File Name : <s:property value="uploadFileFileName"/> <br>
   Content Type : <s:property value="uploadFileContentType"/> <br>
   Temp File Name : <s:property value="uploadFile"/>
   </body>
   </html>

动作类：

package java4s;
import java.io.File;
import java.sql.*;

import org.apache.commons.io.FileUtils;

import com.opensymphony.xwork2.ActionSupport;

public class LogingEx extends ActionSupport{
    private static final long serialVersionUID = 1L;

    private File uploadFile;
    private String uploadFileContentType;
    private String uploadFileFileName;


    public File getUploadFile() {
        return uploadFile;
    }
    public void setUploadFile(File uploadFile) {
        this.uploadFile = uploadFile;
    }

    public String getUploadFileContentType() {
        return uploadFileContentType;
    }
    public void setUploadFileContentType(String uploadFileContentType) {
        this.uploadFileContentType = uploadFileContentType;
    }

    public String getUploadFileFileName() {
        return uploadFileFileName;
    }
    public void setUploadFileFileName(String uploadFileFileName) {
        this.uploadFileFileName = uploadFileFileName;
    }

    public String execute()
    {

        try{
        String filePath = "c:/Myuploads";  // Path where uploaded file will be stored
        System.out.println("Server path:" + filePath); // check your path in console
        File fileToCreate = new File(filePath, uploadFileFileName);// Create file name  same as original
        FileUtils.copyFile(uploadFile, fileToCreate); // Just copy temp file content tos this file      
        System.out.println("inside database");
        Class.forName("oracle.jdbc.driver.OracleDriver");  
        Connection con=DriverManager.getConnection("jdbc:oracle:thin:@10.10.1.62:1521:mcrtest","SULTAN","SULTAN");
        PreparedStatement statement = con.prepareStatement("insert into filedatabase " +"(name, type, path)" + "values(?,?,?)");
        statement.setString(1,uploadFileFileName);
        statement.setString(2,uploadFileContentType);
        statement.setString(3,uploadFile.toString());
        System.out.println("After database");
        statement.close();
        con.close();

        }catch(Exception e)
        {
            e.printStackTrace();
            addActionError(e.getMessage());
            return INPUT;

        }


        return SUCCESS;
    }
