Spring Boot，Spring Security覆盖UserDetailsService

Question

致力于从Spring Security xml配置移动到Spring Security中的Java配置。

在我的类SecurityConfiguration中，它扩展了WebSecurity配置适配器。然而，问题是安全过滤器（特别是UsernamePasswordAuthenticationFilter）没有使用userDetailsService。我查看了启动，似乎这不是在Spring boots创建默认InMemoryUserDetailsManager之前创建的。

@Configuration
@EnableWebMvcSecurity
@Order(SecurityProperties.ACCESS_OVERRIDE_ORDER)
public class SecurityConfiguration extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(HttpSecurity http)
      throws Exception {

      http.userDetailsService(userDetailsService);

    }
}

我还尝试使用自定义注入的ApplicationUserDetailsService重写此类中的userDetailsServiceBean和userDetailsService。

@Bean(name="myUserDetailsBean")
@Override
public UserDetailsService userDetailsServiceBean() {
    return userDetailsService;
}

@Override
public UserDetailsService userDetailsService() {

    return userDetailsService;
}

然而，当我试图覆盖身份验证管理器Bean时，它看起来像是在Spring启动配置初始化之前调用了我的配置，但是它抛出一个错误（如下），即初始化UsernamePasswordAuthenticationFilter时有一个循环引用。我真的需要覆盖身份验证管理器Bean吗，因为我需要定义进入UsernamePasswordAuthenticationFilter的内容。

@Bean(name="myAuthenticationManager")
@Override
public AuthenticationManager authenticationManagerBean() throws Exception {
    return super.authenticationManagerBean();
}

..

Caused by: org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.security.web.authentication.UsernamePasswordAuthenticationFilter]: Circular reference involving containing bean 'securityBeansConfiguration' - consider declaring the factory method as static for independence from its containing instance.

嗨，有一种简单的方法可以覆盖UserDetailsService

import com.dog.care.domain.User;
import com.dog.care.repository.UserRepository;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.core.userdetails.UsernameNotFoundException;
import org.springframework.stereotype.Component;
import org.springframework.transaction.annotation.Transactional;

import javax.inject.Inject;
import java.util.Optional;

@Component("userDetailsService")
public class UserDetailsService implements org.springframework.security.core.userdetails.UserDetailsService {

private final Logger log = LoggerFactory.getLogger(UserDetailsService.class);

@Inject
private UserRepository userRepository;

@Override
@Transactional
public UserDetails loadUserByUsername(final String login) {
    log.debug("Authenticating {}", login);
    String lowercaseLogin = login.toLowerCase();
    Optional<User> userFromDatabase =  userRepository.findOneByLogin(lowercaseLogin);
    return userFromDatabase.map(user -> {
        if (!user.getActivated()) {
            throw new UserNotActivatedException("User " + lowercaseLogin + " was not activated");
        }
        return new CustomUserDetails(user);
    }).orElseThrow(() -> new UsernameNotFoundException("User " + lowercaseLogin + " was not found in the database"));
}
}

这很重要：@组件（“userDetailsService”）

谢谢Aleksandar
