Question

我无法在春季使用MongoDB使用Spring Security进行身份验证。

实体：

@Document(collection = "users")
public class Users {

    @Id
    private String id;
    private String username;
    private String email;
    private String password;
    private List<Notification> preferences;


    public Users(String username, String email, String password, List<Notification> preferences) {
        this.username = username;
        this.email = email;
        this.password = password;
        this.preferences = preferences;
    }

    public String getUsername() {
        return username;
    }

    public void setUsername(String username) {
        this.username = username;
    }

    public String getEmail() {
        return email;
    }

    public void setEmail(String email) {
        this.email = email;
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }

    public List<Notification> getPreferences() {
        return preferences;
    }

    public void setPreferences(List<Notification> preferences) {
        this.preferences = preferences;
    }
}

服务：

@Component
public class MongoUserDetailsService implements UserDetailsService {

    @Autowired
    private UserRepository repository;

    @Override
    public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
        Users user = repository.findByUsername(username);

        if(user == null) {
            throw new UsernameNotFoundException("User not found");
        }

        List<SimpleGrantedAuthority> authorities = Arrays.asList(new SimpleGrantedAuthority("user"));

        return new User(user.getUsername(), user.getPassword(), authorities);
    }
}

存储库：

import com.example.Start.entities.Users;
import org.springframework.data.mongodb.repository.MongoRepository;
import org.springframework.stereotype.Repository;

@Repository
public interface UserRepository extends MongoRepository<Users, String> {
    Users findByUsername(String username);
}

配置：

    @Configuration
    @EnableConfigurationProperties
    public class SecurityConfiguration extends WebSecurityConfigurerAdapter {

        @Autowired
        MongoUserDetailsService userDetailsService;

        @Override
        protected void configure(HttpSecurity http) throws Exception {
            http
                    .csrf().disable()
                    .authorizeRequests().anyRequest().authenticated()
                    .and().httpBasic()
                    .and().sessionManagement().disable();
        }

        @Bean
        public PasswordEncoder passwordEncoder() {
            return new BCryptPasswordEncoder();
        }

        @Override
        public void configure(AuthenticationManagerBuilder builder) throws Exception {
            builder.userDetailsService(userDetailsService);
        }
    }

当我尝试进行身份验证时，它会给我以下信息： enter image description here

在我的数据库中，我有这个用户：

{
    "_id" : ObjectId("5b855813d03cce0264de3ab6"),
    "username" : "username",
    "email" : "test@test.com",
    "password" : "123"
}

你知道是什么原因造成的吗？

问题是您已将BCryptPasswordEncoder注册为passwordEncoder bean，但密码已以明文形式存储在数据库中。现在，当进行身份验证时，它将使用BCrypt算法对来自HTTP请求的传入密码进行编码，并将其与明文密码进行比较，这显然会失败。这就是为什么您得到“编码密码看起来不像BCrypt”的原因，因为它不是。

简短的解决方法是将您的mongodb用户记录编辑为具有用户名“ username”的用户的密码字段具有以下值：

{
    "_id" : ObjectId("5b855813d03cce0264de3ab6"),
    "username" : "username",
    "email" : "test@test.com",
    "password" : "$2a$10$pIUUIHClmGYBnsJzlOHQkeecSwRGAgYlxzRfBFjEqhk6rkQdilTYC"
}

使用BCrypt算法对字符串“ 123”进行编码时，您将获得“ $ 2a $ 10 $ pIUUIHClmGYBnsJzlOHQkeecSwRGAgYlxzRfBFjEqhk6rkQdilTYC”。

但是正确的修复方法是添加代码以对密码进行编码，然后再将其保存在应用程序的Mongo数据库中，如下所示：

@Autowired
private PasswordEncoder passwordEncoder;

public void saveUser(Users user) {
    user.setPassword(passwordEncoder.encoder(user.getPassword()));
    // Save in mongodb
}
