若依框架 、Spring Security、 第三方登录认证，短信登录，邮箱验证码登录，SSO 单点登录、JWT

背景：后端开发使用 Spring Security 框架，默认登录验证是用户名，密码，需求是可以通过验证码登录，或者其他系统携带用户信息（比如登录用户名）来验证登录

重写 WebSecurityConfigurerAdapter 的configure() 方法指定自定义检验器
自定义校验器实现AuthenticationProvider重写 authenticate() 这个检验方法 和supports() ,从而进行重写验证方式并且加载权限。

获取验证码

@PostMapping("/authCode")
@ApiOperation("获取验证码")
public AjaxResult authCode(String username) {
    AjaxResult ajax = new AjaxResult();
    String code = getSixNum();
    // 给用户发送验证码
    // sendMsgUtil.send(username,code)
    redisCache.setCacheObject(username,code,60*2, TimeUnit.SECONDS);
    ajax.put("code", code);
    return ajax;
}

/**
 * 生成六位随机数
 * @return
 */
public static String getSixNum() {
    String str = "0123456789";
    StringBuilder sb = new StringBuilder(4);
    for (int i = 0; i < 6; i++) {
        char ch = str.charAt(new Random().nextInt(str.length()));
        sb.append(ch);
    }
    return sb.toString();
}

验证码登录

@PostMapping("/thirdLogin")
@ApiOperation("三方验证码登录")
public AjaxResult thirdLogin(String username, String code) {
    AjaxResult ajax = new AjaxResult();
    String userToken = loginService.thirdLogin(username, code);
    ajax.put(Constants.TOKEN, userToken);
    return ajax;
}

login实现类

@Service
public class LoginServiceImpl implements LoginService {
    private static final Logger log = LoggerFactory.getLogger(LoginServiceImpl2.class);
    @Resource
    private AuthenticationManager authenticationManager;
    @Autowired
    private TokenService tokenService;
    
    /**
     * 登录验证
     *
     * @param username 用户名
     * @param code 验证码
     * @return 结果 token
     */
    @Override
    public String thirdLogin(String username, String code) {
        // 用户验证
        Authentication authentication = null;
        try {
            // 该方法会去调用UserDetailsServiceImpl.loadUserByUsername
            authentication = authenticationManager.authenticate(new UsernamePasswordAuthenticationToken(username, code));
        } catch (Exception e) {
            if (e instanceof BadCredentialsException) {
                throw new UserPasswordNotMatchException();
            } else {
                throw new CustomException(e.getMessage());
            }
        }
        Object principal = authentication.getPrincipal();
        LoginUser loginUser = (LoginUser) principal;
        // 生成token
        return tokenService.createToken(loginUser);
    }
}

修改认证配置

自定义MyAuthenticationProvider类

package com.ruoyi.framework.config;

import com.ruoyi.common.exception.user.UserPasswordNotMatchException;
import com.ruoyi.framework.redis.RedisCache;
import com.ruoyi.framework.security.service.UserDetailsServiceImpl;

import org.springframework.security.authentication.AuthenticationProvider;
import org.springframework.security.authentication.UsernamePasswordAuthenticationToken;
import org.springframework.security.core.Authentication;
import org.springframework.security.core.AuthenticationException;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
import org.springframework.stereotype.Component;

@Component
public class MyAuthenticationProvider implements AuthenticationProvider {

    @Autowired
    private RedisCache redisCache;

    @Autowired
    private UserDetailsServiceImpl userDetailsService;

    @Autowired
    private BCryptPasswordEncoder bCryptPasswordEncoder;

    @Override
    public Authentication authenticate(Authentication authentication) throws AuthenticationException, UserPasswordNotMatchException {
        String name = authentication.getName();
        String password = (String) authentication.getCredentials();
        UserDetails user = userDetailsService.loadUserByUsername(name);
        String encoderPassword = bCryptPasswordEncoder.encode(password);
        // 数据库账号密码的校验能通过就通过
        if (bCryptPasswordEncoder.matches(password, user.getPassword())) {
            return new UsernamePasswordAuthenticationToken(user, encoderPassword);
        }
        Boolean checkValid = checkValid(name, password);
        if (checkValid && null != user) {
            return new UsernamePasswordAuthenticationToken(user, password);
        } else {
            // 如果都登录不了，就返回异常输出
            throw new UserPasswordNotMatchException();
        }
    }

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


    /**
     * 非账号密码登录-验证合法
     * @param userName
     * @param pwd
     */
    public boolean checkValid(String userName, String pwd) {
        Object code = redisCache.getCacheObject(userName);
        if (null != code &&  code.toString().equals(pwd)) {
            return true;
        }
        return false;
    }
