Spring Framework intro

• Add all needed dependencies. Adding Spring dependencies use the same version for each of them. For this purpose you can use property spring.version. See example in <artifactId>spring-test</artifactId> dependency.

• Implement UserService and UserDao

    public interface UserService {
        User add(User user);
    
        List<User> getAll();
    }

• User should have age, name fields and overridden equals() and hashcode() methods

• In the Main class configure ApplicationContext and show how you are saving User into DB and reading him back

• Configure DataSource
