需求：A管理员在微信端提交用户加入群组，给B高级管理员审核。

           B管理员审核成功后，微信公众号会发送一个消息给A管理员，提示新增成功。

微信后台模板消息接口：

官方文档：

        请求需要三个参数——

        touser：用户的微信openId

        template_id:模板消息id

        topcolor：字体颜色

        data：替换模板消息内的具体数据

            String openId = null;

                tem.setTopColor("#00DD00");

                // 获取accessToken
                String token = null;
                try {
                    token = WeiXinUtil.getAccessToken().getToken();
                } catch (Exception e) {
                    e.printStackTrace();

                boolean result = sendTemplateMsg(token, tem);
                logger.info("模板消息发送结果：" + result);

工具类：



public class WeiXinUtil {
    
    @Value("${wx.appId}")
    private static String APPID;
    
    @Value("${wx.appsecret}")
    private static String APPSECRET;

    // private static final String APPSECRET = "93e787d23e2e1e5c45d1c7f5cdc6fe79";
    private static final String ACCESS_TOKEN_URL =
        "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=APPID&secret=APPSECRET";
    
    /**
     * 编写Get请求的方法。但没有参数传递的时候，可以使用Get请求
     * 
     * @param url 需要请求的URL
     * @return 将请求URL后返回的数据，转为JSON格式，并return
     */
    public static JSONObject doGetStr(String url) throws ClientProtocolException, IOException {
        DefaultHttpClient client = new DefaultHttpClient();// 获取DefaultHttpClient请求
        HttpGet httpGet = new HttpGet(url);// HttpGet将使用Get方式发送请求URL
        JSONObject jsonObject = null;
        HttpResponse response = client.execute(httpGet);// 使用HttpResponse接收client执行httpGet的结果

发送模板消息调用方法：

 // 发送模板消息
    public static boolean sendTemplateMsg(String token, Template template) {
        
        boolean flag = false;
        
        String requestUrl = "https://api.weixin.qq.com/cgi-bin/message/template/send?access_token=ACCESS_TOKEN";
        requestUrl = requestUrl.replace("ACCESS_TOKEN", token);
        
        JSONObject jsonResult = CommonUtil.httpsRequest(requestUrl, "POST", template.toJSON());
        if (jsonResult != null) {
            int errorCode = jsonResult.getInteger("errcode");
            String errorMessage = jsonResult.getString("errmsg");
            if (errorCode == 0) {
                flag = true;
            } else {
                System.out.println("模板消息发送失败:" + errorCode + "," + errorMessage);
                flag = false;
            }
        }
        return flag;
    }

发送消息时需要的CommonUtil


 
public class CommonUtil {

        JSONObject jsonObject = null;

            sslContext.init(null, tm, new java.security.SecureRandom());  
            // 从上述SSLContext对象中得到SSLSocketFactory对象  
            SSLSocketFactory ssf = sslContext.getSocketFactory();  
  
            URL url = new URL(requestUrl);  
            HttpsURLConnection httpUrlConn = (HttpsURLConnection) url.openConnection();
