Question

我使用以下代码使用html和java servlet上传文件。

但是我无法打印位置或检索上传文件的路径的值。

请帮我解决一下我是如何打印出来的。我想在我的servlet文件中打印例如：d:/new/filename。提前致谢。以下是我的代码段：

**index.html**

<html>  
<body>  
<form action="go" method="post" enctype="multipart/form-data">  
Select File:<input type="file" name="fname"/><br/>  
<input type="submit" value="upload"/>  
</form>  
</body>  
</html> 

**UploadServlet.java**

import java.io.*;  
import javax.servlet.ServletException;  
import javax.servlet.http.*;  
import com.oreilly.servlet.MultipartRequest;  

public class UploadServlet extends HttpServlet {  

public void doPost(HttpServletRequest request, HttpServletResponse response)  
    throws ServletException, IOException {  

response.setContentType("text/html");  
PrintWriter out = response.getWriter();  

MultipartRequest m=new MultipartRequest(request,"d:/new");  
out.print("successfully uploaded");  
}  
}   


***web.xml***

<web-app>  

<servlet>  
<servlet-name>UploadServlet</servlet-name>  
<servlet-class>UploadServlet</servlet-class>  
</servlet>  

<servlet-mapping>  
<servlet-name>UploadServlet</servlet-name>  
<url-pattern>/go</url-pattern>  
</servlet-mapping>  

</web-app>

Answer 1

我会试试

out.print("successfully uploaded in" + m.getFilesystemName("fname"));

无法使用jsp和servlet打印上传文件的名称
