spring boot整合第三方微信开发工具 weixin-java-miniapp 实现小程序微信登录

有时候项目需要用到微信登录或获取用户的手机号码，weixin-java-miniapp是一个好用的第三方工具，不用我们自己写httpcline调用。

导入jar包

<dependency>

            <groupId>com.github.binarywang</groupId>

            <artifactId>weixin-java-miniapp</artifactId>

            <version>4.1.0</version>

</dependency>

添加一个resource.properties文件，写上小程序的appid和secret

wx.miniapp.appid: xxxxxxxxxxxx
wx.miniapp.secret: xxxxxxxxxxxxxxxxxxxxxxxxxx
wx.miniapp.msgDataFormat: JSON

添加两个配置文件

WxMaProperties.java

@ConfigurationProperties(prefix = "wx.miniapp")
public class WxMaProperties {

    /**
     * 设置微信小程序的appid
     */
    private String appid;

    /**
     * 设置微信小程序的Secret
     */
    private String secret;

    /**
     * 消息格式，XML或者JSON
     */
    private String msgDataFormat;

    public String getAppid() {
        return appid;
    }

    public void setAppid(String appid) {
        this.appid = appid;
    }

    public String getSecret() {
        return secret;
    }

    public void setSecret(String secret) {
        this.secret = secret;
    }

    public String getMsgDataFormat() {
        return msgDataFormat;
    }

    public void setMsgDataFormat(String msgDataFormat) {
        this.msgDataFormat = msgDataFormat;
    }

WxMaConfiguration.java

@Configuration


@EnableConfigurationProperties(WxMaProperties.class)

public class WxMaConfiguration {



    @Bean

    public WxMaService wxMaService(WxMaProperties properties) {

        WxMaDefaultConfigImpl config = new WxMaDefaultConfigImpl();

        config.setAppid(properties.getAppid());

        config.setSecret(properties.getSecret());

        config.setMsgDataFormat(properties.getMsgDataFormat());



        WxMaService service = new WxMaServiceImpl();

        service.setWxMaConfig(config);

        return service;

    }

}

如何使用

@Autowired


private WxMaService wxMaService;



    @ApiOperation("获取微信授权信息")

    @ApiImplicitParam(name = "code",value = "前端授权登录后传来的code", required = true,paramType = "query")

    @RequestMapping(value = "/wechatSession", method = RequestMethod.POST)

    @ResponseBody

    public ResponseResult wechatSession(@RequestParam String code) {

        //获取openId、unionid、session_key

        WxMaJscode2SessionResult sessionInfo = wxMaService.getUserService().getSessionInfo(code);

    }





    @ApiOperation("小程序手机号登录")

    @ApiImplicitParams({

            @ApiImplicitParam(name = "sessionKey", value = "sessionKey", paramType = "query", dataType = "string", required = true),

            @ApiImplicitParam(name = "encryptedData", value = "加密串", paramType = "query", dataType = "string", required = true),

            @ApiImplicitParam(name = "iv", value = "偏移量", paramType = "query", dataType = "string", required = true)

    })

    @RequestMapping(value = "/wechatLogin", method = RequestMethod.POST)

    @ResponseBody

    public ResponseResult wechatLogin(HttpServletRequest request,                                     

                                      @RequestParam @NotBlank(message = "sessionKey不能为空") String sessionKey,                                    

                                      @RequestParam @NotBlank(message = "加密串不能为空") String encryptedData,

                                      @RequestParam @NotBlank(message = "偏移串不能为空") String iv) {

        WxMaPhoneNumberInfo phoneInfo = wxMaService.getUserService().getPhoneNoInfo(sessionKey, encryptedData, iv);

        return phoneInfo.getPurePhoneNumber(); 

    }

在resource.properties添加相关类型的消息通知id，在申请小程序那配置

 @Value("${wx.miniapp.msg.template_id_1}")
    private String msgTemplateId1;

    @Value("${wx.miniapp.msg.template_id_2}")
    private String msgTemplateId2;

/**
openId : 用户微信登录的openID
*/
   private boolean sendSubscribeMessage(String openId) {
        String page="pages/index/index"; // 应该是消息点击后跳转页面
        WxMaSubscribeMessage message = new WxMaSubscribeMessage();
        message.setTemplateId(msgTemplateId1);
        message.setToUser(openId);
        message.setPage(page);
        List subscribeDataList = new ArrayList<>();
        WxMaSubscribeMessage.MsgData subscribeData = new WxMaSubscribeMessage.MsgData();
        subscribeData.setName("key1"); // 你在小程序自定义的key(比如“商家名称”)
        subscribeData.setValue("奈雪的茶"); //key对应的内容
        //添加你配置要且要展示的内容
        subscribeDataList.add(subscribeData);
   
        message.setData(subscribeDataList);
        try {
            wxMaService.getMsgService().sendSubscribeMsg(message);
            return true;
        } catch (WxErrorException e) {
            log.error("发送小程序订阅消息失败，errCode:{}，errMsg:{}", e.getError().getErrorCode(), e.getError().getErrorMsg());
        }
        return false;
    }
