flowchart TD
    A(创建User实体类) --> B(创建UserRepository接口)
    B --> C(创建UserService类)
    C --> D(创建CustomUserDetailsService类)
    D --> E(创建CustomAuthenticationFailureHandler类)
    E --> F(创建SecurityConfig类)

步骤一：创建User实体类

@Entity
@Table(name = "users")
public class User {
    
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;
    
    @Column(nullable = false, unique = true)
    private String username;
    
    @Column(nullable = false)
    private String password;
    
    private boolean accountNonLocked = true;
    
    // 省略getter和setter
}

步骤二：创建UserRepository接口

public interface UserRepository extends JpaRepository<User, Long> {

    User findByUsername(String username);
    
}

步骤三：创建UserService类

@Service
public class UserService 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 user;
    }
    
}

步骤四：创建CustomUserDetailsService类

public class CustomUserDetailsService extends UserService {
    
    @Override
    public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
        User user = userRepository.findByUsername(username);
        if (user == null) {
            throw new UsernameNotFoundException("User not found");
        }
        if (!user.isAccountNonLocked()) {
            throw new LockedException("User account is locked");
        }
        return user;
    }
    
}

步骤五：创建CustomAuthenticationFailureHandler类

@Component
public class CustomAuthenticationFailureHandler extends SimpleUrlAuthenticationFailureHandler {
    
    @Autowired
    private UserRepository userRepository;
    
    @Override
    public void onAuthenticationFailure(HttpServletRequest request, HttpServletResponse response, AuthenticationException exception) throws IOException, ServletException {
        super.onAuthenticationFailure(request, response, exception);
        
        User user = userRepository.findByUsername(request.getParameter("username"));
        if (user != null) {
            user.setAccountNonLocked(false);
            userRepository.save(user);
        }
    }
    
}

步骤六：创建SecurityConfig类

@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
    
    @Autowired
    private CustomUserDetailsService customUserDetailsService;
    
    @Autowired
    private CustomAuthenticationFailureHandler customAuthenticationFailureHandler;
    
    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.userDetailsService(customUserDetailsService).passwordEncoder(passwordEncoder());
    }
    
    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
            .formLogin()
                .loginPage("/login")
                .failureHandler(customAuthenticationFailureHandler)
                .permitAll()
            .and()
            .logout()
                .permitAll()
            .and()
            .authorizeRequests()
                .antMatchers("/resources/**").permitAll()
                .anyRequest().authenticated();
    }
    
    @Bean
    public PasswordEncoder passwordEncoder() {
        return new BCryptPasswordEncoder();
    }
    
}

通过以上步骤，你就可以实现Spring Boot验证失败锁定用户的功能了。希望对你有所帮助！
