Java Servlet 和 JSP，如何从文件中获取完整路径名？
Java Servlet and JSP, How to get full path name from a file?
当我使用 request.getParameter("txtPhoto");它 returns 文件名 (image.jpg) 但我想获取完整路径名 (C:\Images\image.jpg) 因为我需要完整的位置来将文件保存在 MySQL 数据库。我希望你能帮助我。
------------------------JSP页数
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Upload</title>
</head>
<body>
<form action="ImageController" method="post">
<h1>File</h1>
<input type="file" name="txtPhoto" placeholder="Upload Your Image" accept="image/gif, image/jpeg, image/png" /><br /><br />
<input type="submit" value="Save">
</form>
</body>
</html>
----------------Servlet
@WebServlet(name = "ImageController", urlPatterns = {"/ImageController"})
public class imagenservlet extends HttpServlet
{
protected void processRequest(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException
{
if(request.getParameter("txtPhoto") == null)
{
response.sendRedirect("upload.jsp");
return;
}
PrintWriter out = response.getWriter();
FileInputStream input = null;
File theFile = new File(request.getParameter("txtPhoto"));
input = new FileInputStream(theFile);
out.println("FullPathname" + " " + theFile.getAbsolutePath());
}
}
您无法获取本地文件路径，因为它在服务器端没有用。它只会对黑客有用。这就是浏览器不发送它的原因。
在 JSP 端声明隐藏的 [=10th=] 变量，将所需的路径分配给该隐藏变量并在 servlet 中获取该变量，它只是解决问题。
