[java, spring]Question about setting up an intelligence.

Recently, I started studying spring, so I'm not used to Intellie J. Until yesterday, the spring project worked properly, but when I imported the new project yesterday and used it and accessed the spring project again today, the .java mark came out as shown in Figure 2, and it didn't even build by class.

I want to set it up so that it comes out as Java class right away like picture number 1, is there any solution?

For your information, the spring project seems to be using a gradle because there is a .gradle in the root folder
