My pom.xml When I added this dependencies - I had reloaded my project and run it. When I debug it - It shows, that .web package is RED(not found) . Maybe some dependencies are incorrect or their versions are not the same.

And the running class
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class SpringClient {
public static void main(String[] argv){
SpringApplication.run(SpringClient.class);
}
}
Pls help me, if you can. Or if you will find my mistake, pls write how to correct it:)
That is the result.

The first line of your debug message has answer, @SpringBootApplication annotated class can't be in default package.
Create java package and refactor this class to new package.
