IntelliJ Configuration

Once you import the Maven proyect, you have to do the following to activate IntelliJ support for Spring:

1. Right click on the proyect root foolder and select Add framework support...
2. In the window that opens, select Spring and in the center choose Set up the library later. Then press OK.
3. Now go to the SampleController class. There is a warning in the class name. Use Control+Enter and fix it. It will open a new window but you have to change nothing.
