一、引入核心pom

        <!-- 微信小程序 --><dependency><groupId>com.github.binarywang</groupId><artifactId>weixin-java-miniapp</artifactId><version>4.5.0</version></dependency><dependency><groupId>org.apache.commons</groupId><artifactId>commons-lang3</artifactId><version>3.12.0</version></dependency>

二、注入依赖配置

import cn.binarywang.wx.miniapp.api.WxMaService;
import cn.binarywang.wx.miniapp.api.WxMaUserService;
import cn.binarywang.wx.miniapp.api.impl.WxMaServiceImpl;
import cn.binarywang.wx.miniapp.config.impl.WxMaDefaultConfigImpl;
import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;import javax.annotation.PostConstruct;@Slf4j
@Configuration
public class WxClientConfig {//小程序服务@Value("${wx.mini.appId}")private String miniAppId;@Value("${wx.mini.secret}")private String miniSecret;private WxMaUserService wxMaUserService;@PostConstructpublic void init() {//微信小程序WxMaDefaultConfigImpl wxMaConfig = new WxMaDefaultConfigImpl();wxMaConfig.setAppid(miniAppId);wxMaConfig.setSecret(miniSecret);WxMaService wxMaService = new WxMaServiceImpl();wxMaService.setWxMaConfig(wxMaConfig);this.wxMaUserService = wxMaService.getUserService();}@Bean(name = "wxMaUserService")public WxMaUserService wxMaUserService(){return this.wxMaUserService;}

三、跟进微信CODE 获取openId

    @Resourceprivate WxMaUserService wxMaUserService;//根据授权code获取微信用户信息WxMaJscode2SessionResult session = wxMaUserService.getSessionInfo(authDto.getCode());WxMaUserInfo wxUser = wxMaUserService.getUserInfo(session.getSessionKey(), authDto.getEncryptedData(), authDto.getIv());

四、根据微信CODE 获取手机信息

            String phoneNumber = wxMaUserService.getPhoneNoInfo(bindDto.getCode()).getPhoneNumber();
