java - springBoot+spring security+Kaptcha如何实现图片验证码

Question

@Component
public class MyAuthenticationProvider implements AuthenticationProvider {


    @Autowired
    private CustomUserDetailsService userService;
    @Override
    public Authentication authenticate(Authentication authentication) throws AuthenticationException {
        String username = authentication.getName();
        String password = (String) authentication.getCredentials();
        CustomUserDetails user = (CustomUserDetails) userService.loadUserByUsername(username);
        if(user == null){
            throw new BadCredentialsException("用户不存在");
        }

        if (!password.equals(user.getPassword())) {
            throw new BadCredentialsException("错误的密码");
        }

        Collection<? extends GrantedAuthority> authorities = user.getAuthorities();
        return new UsernamePasswordAuthenticationToken(user, password, authorities);
    }

    @Override
    public boolean supports(Class<?> arg0) {
        return true;
    }


}

在springBoot项目中有这个类验证用户名和密码。现在想添加图片验证码（Kaptcha）该如何实现？？？

Answer 1

このクラスを書き換えて、それに検証コード検証を追加します
これは、Shiro による検証コードを追加する別の例です

public class CaptchaFormAuthenticationFilter extends FormAuthenticationFilter{
