Syntax Error - @PostConstructor Annotation

I am following a tutorial of Spring. In the example it has created a method with @PostConstructor annotation. But I am trying to put but Spring throws me like a Syntax Error.

Then Spring provide me 3 options:

• Createa Annotation


• Rename in file


• Fix Project setup

Some one know what have I to do?

package cr.test.jba.service;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import cr.test.jba.entity.Role;
import cr.test.jba.repository.BlogRepository;
import cr.test.jba.repository.ItemRepository;
import cr.test.jba.repository.RoleRepository;
import cr.test.jba.repository.UserRepository;


@Service
public class InitDbService {

    @Autowired
    private RoleRepository roleRepository;

    @Autowired
    private UserRepository userRepository;

    @Autowired
    private BlogRepository blogRepository;

    @Autowired
    private ItemRepository itemRepository;

    @PostConstruct
    public void init(){
        Role roleUser = new Role();
        roleUser.setName("ROLE_USER");
    }

And applicationContext:
