CodePudding user response:

Whether to hand in the server automatically created this folder?

CodePudding user response:

Don't put the project folder subjects, on the outside, look at the web server, isn't that right,

CodePudding user response:

Empty folder won't deploy, need inside literally put a file,

Maven is the problem,

CodePudding user response:

See you how to deploy the project, it is better to the classpath, do not use the servletContext

 
Public class TestCode {

Public static void main (String [] args) {
String classpath=TestCode. Class. GetResource ("/"). GetPath (); 
String projectPath=new File (the classpath). GetParentFile () getParentFile () getAbsolutePath (); 
System. Out. Println (" class="+ classpath). 
System. The out. Println (" project root directory="+ projectPath); 
} 

}

 
The classpath=/D:/app/project/muddy/test/WebRoot/WEB - INF/classes/
Project root directory=D: \ app \ project \ muddy \ test \ WebRoot

You can try

 request. GetSession (). GetServletContext () getRealPath ("/") + "/upload"
