由于不明原因，MyUserDetailsService中的My UsersRepository spring jpa返回null。
那么如何解决在MyUserDetailsService类中自动接线的null？
我尝试了很多方法，但是MyUserDetailsService中的UsersRepository spring jpa始终返回null。
似乎spring不能从调度程序中扫描bean并注入到我的UsersRepository？是真的吗？
这是我的代码：
import java.util.ArrayList;
import java.util.List;
import java.util.Optional;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.security.core.GrantedAuthority;
import org.springframework.security.core.authority.SimpleGrantedAuthority;
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.Component;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;
import Repository.UsersRepository;
import entity.users;
import securityConfig.MyUserDetails;
@Component
public class MyUserDetailsService implements UserDetailsService{
@Autowired
private UsersRepository usersrepo;
@Override
public UserDetails loadUserByUsername(String userName) throws UsernameNotFoundException {
try {
Optional<users> user=usersrepo.findByName(userName);
} catch (Exception e) {
System.out.println(e);
}
System.out.println("USER NAME NHAN DC LA: "+userName);
if(!"NhatNam".equalsIgnoreCase(userName)) throw new UsernameNotFoundException("User name not found");
String password = "123";
List<GrantedAuthority> authorities = new ArrayList<GrantedAuthority>();
SimpleGrantedAuthority authority = new SimpleGrantedAuthority("ROLE_TEACHER");
authorities.add(authority);
MyUserDetails userDetail = new MyUserDetails(userName, password, authorities);
return userDetail;
}
}
我尝试将jpa配置添加到我的spring-security.xml中，并出现错误：
