在服务器上保存文件，java web应用程序
来自我的Web应用程序（vaadin）我生成XML文件并希望将这些文件存储在服务器上。我做了：
from my web application (vaadin) I generate XML files and want to store these files on the server. I did:
context.getHttpSession().getServletContext().getRealPath("/");
我在tomcat上运行web应用并设法将文件保存到
下的app文件夹>I run the web app on tomcat and managed to save the file to the app folder under
.metadata/.plugins/org.eclipse.wst.server.core/tmp0/wtpwebapps/my_app_folder/
与META-INF，WEB-INF和VAADIN文件夹处于同一级别。如果我想将文件保存在服务器存储上并将文件路径保存在数据库中，我应该在哪里保存文件？谢谢
on the same level with META-INF, WEB-INF and VAADIN folder. If I want to save the file on server storage and save the path of the file on the database, where should I save the files? Thank you
您的Web应用程序在服务器上的JVM中运行。应用程序的根文件路径通常是Tomcat服务器的文件夹。要获取此文件夹路径，您可以轻松执行以下操作：
Your web application runs within a JVM on the Server. The root file path of your application is typically the folder of your Tomcat Server. To get this folder path you can easily do the following:
String sRootPath = new File("").getAbsolutePath();
您可以将文件保存在由您创建的子文件夹中，或者您在服务器上的某处有一个额外的文件夹filesystem。
You could save your files in a subfolder created by you or you have an extra folder somewhere on the servers filesystem.
