当Spring Security对用户进行身份验证时,如何在会话中管理自定义用户对象？

@Service
public class CustomUserDetailsService implements UserDetailsService {

    @Autowired
    private UserRepository userRepository;

    @Override
    public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
        User user = userRepository.findByUsername(username);
        if (user == null) {
            throw new UsernameNotFoundException("User not found");
        }
        return new CustomUserDetails(user);
    }
}

public class CustomUserDetails implements UserDetails {

    private User user;

    public CustomUserDetails(User user) {
        this.user = user;
    }

    @Override
    public Collection<? extends GrantedAuthority> getAuthorities() {
        // 返回用户权限列表
    }

    @Override
    public String getPassword() {
        return user.getPassword();
    }

    @Override
    public String getUsername() {
        return user.getUsername();
    }

    @Override
    public boolean isAccountNonExpired() {
        // 判断账户是否未过期
    }

    @Override
    public boolean isAccountNonLocked() {
        // 判断账户是否未锁定
    }

    @Override
    public boolean isCredentialsNonExpired() {
        // 判断凭证是否未过期
    }

    @Override
    public boolean isEnabled() {
        // 判断账户是否启用
    }
}

@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Autowired
    private CustomUserDetailsService customUserDetailsService;

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.authenticationProvider(daoAuthenticationProvider());
    }

    @Bean
    public DaoAuthenticationProvider daoAuthenticationProvider() {
        DaoAuthenticationProvider provider = new DaoAuthenticationProvider();
        provider.setUserDetailsService(customUserDetailsService);
        provider.setPasswordEncoder(passwordEncoder());
        return provider;
    }

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

@GetMapping("/user")
public String user(@AuthenticationPrincipal CustomUserDetails customUserDetails) {
    // 使用自定义用户对象
}
