授权核心

public AuthorizeResponse authorize( WxUserRegisterRequest registerRequest) {
            try {
                WxMaJscode2SessionResult session = Wxconfig.wxService.getUserService().getSessionInfo(registerRequest.getCode());
                String accessToken = Wxconfig.wxService.getAccessToken();
                WxMaUserInfo userInfo = Wxconfig.wxService.getUserService().getUserInfo(session.getSessionKey(), registerRequest.getEncryptedData(), registerRequest.getIv());
                AuthorizeResponse authorizeResponse = new AuthorizeResponse()
                        .setOpenid(userInfo.getOpenId())
                        .setUnionid(userInfo.getUnionId())
                        .setAccessToken(accessToken)
                        .setSessionKey(session.getSessionKey());
                return authorizeResponse;
            } catch (WxErrorException e) {
                throw new CloudException(ExceptionConstant.DATD_ERROR);
            }
        }

各类实体

WxUserRegisterRequest

@Data
    @Accessors(chain = true)
    public class WxUserRegisterRequest {
    
        private String sessionKey;
        private String encryptedData;
        private String iv;
        private String openid;
        private String unionid;
        private String nickname;
        private String avatar;
        private int gender;
        private String code;
        private String ip;
    
    }

Wxconfig

@Component
    public class Wxconfig {
    
        public static String APPID = "xxx";
    
        /**
         * 设置微信小程序的Secret
         */
        public static String SECRET = "xxx";
    
        /**
         * 设置微信小程序消息服务器配置的token
         */
        public static String token;
    
        /**
         * 设置微信小程序消息服务器配置的EncodingAESKey
         */
        public static String aesKey;
    
        /**
         * 消息格式，XML或者JSON
         */
        public static String msgDataFormat = "JSON";
    
        public   static  WxMaService  wxService;
    
        @PostConstruct
        public  void init(){
           wxService = new WxMaServiceImpl();
            WxMaDefaultConfigImpl config = new WxMaDefaultConfigImpl();
            config.setAppid(Wxconfig.APPID);
            config.setSecret(Wxconfig.SECRET);
            wxService.setWxMaConfig(config);
        }
    
    
    }

AuthorizeResponse

@Data
    @Accessors(chain = true)
    public class AuthorizeResponse  {
        private String sessionKey;
        private String openid;
        private String unionid;
        private String accessToken;
    }

之后的登录只要小程序将openid或unionid传上来，然后根据自己的业务处理即可
