There are two ways to write in the import resource path
A classpath, a classpath*
So what's the difference between the two?
1.**classpath: * * only find files in your class path;
2. * * callsspath *: * * not only includes class path, but also includes jar file (class path) for searching, * * * classpath *: * * * is very important for multi module projects
But often we will report Cannot resolve file 'applicationContext.xml' after importing a new project and setting the path
When running localhost:8080, it will report:

Check the path for a while and find that there is no problem. In fact, this problem is almost a problem that should not confuse us. Just like the fans, the simplest one really makes us make mistakes.
Whether the resources file property is set
After clicking: right look
So the path won't go wrong.
