이러한 에러가 자꾸 떠서 다음으로 넘어가질 못하는데요 ...

jap랑 boot 는 다 설정했거던요 ..어디가 문젠지 모르겠어요 maven update계속 해도 마찬가지네요 ..

그리고 서비스파일에

private Collection<? extends GrantedAuthority> authorities() {

return Arrays.asList(new SimpleGrantedAuthority("ROLE_USER"));

}

위에 부분 import가 잘못된건지 아니면 먼가를 빠트렸는지 모르겠네요 다 확인해봐도 정확한 답ㅁ을 못찾겠습니다 .

서비스 파일입니다 .

import java.util.Arrays;

import java.util.Collection;

import java.util.Optional;

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

import org.springframework.security.core.GrantedAuthority;

import org.springframework.security.core.authority.SimpleGrantedAuthority;

import org.springframework.security.core.userdetails.User;

import org.springframework.security.core.userdetails.UserDetails;

import org.springframework.security.core.userdetails.UserDetailsService;

import org.springframework.security.core.userdetails.UsernameNotFoundException;

import org.springframework.stereotype.Service;

@Service

public class AccountService implements UserDetailsService {

@Autowired
private AccountRepositorys accountRepository;
public Account createAccount(String username, String password) {
    Account account = new Account();
    account.setUsername(username);
    account.setPassword(password);
    return accountRepository.save(account);
}
@Override
public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
    Optional<Account> byUserName = accountRepository.findByUsername(username);
    // 없으면 뱉어라
    Account account = byUserName.orElseThrow(() -> new UsernameNotFoundException(username));
    return new User(account.getUsername(), account.getPassword(), authorities());
}
private Collection<? extends GrantedAuthority> authorities() {
    return Arrays.asList(new SimpleGrantedAuthority("ROLE_USER"));
}

}

interface 부분입니다 .

import java.util.Optional;

import org.springframework.data.jpa.repository.JpaRepository;

public interface AccountRepositorys extends JpaRepository<Account, Long> {

Optional findByUsername(String username);

}

runner 부분 입니다 .

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

import org.springframework.boot.ApplicationArguments;

import org.springframework.boot.ApplicationRunner;

public class AccountRunner implements ApplicationRunner {

@Autowired

AccountService accountService;

@Override
public void run(ApplicationArguments args) throws Exception {
    Account account = accountService.createAccount("keesun","1234");
    System.out.println(account.getUsername()+""+account.getPassword());
}

}

maven clean과 project clean 여러번 해서 한번 된거같은데 그떄는 Service쪽에서

Description:

Field accountRepository in com.antMart.com.AccountService required a bean of type 'com.antMart.com.AccountRepositorys' that could not be found.

The injection point has the following annotations:

• @org.springframework.beans.factory.annotation.Autowired(required=true)

Action:

Consider defining a bean of type 'com.antMart.com.AccountRepositorys' in your configuration.

이러한 에러가 발생했습니다 ..STS 사용중이구요 어디가 잘못된건지 모르겠습니다 ;
