springboot 使用微信測試號 給用戶發送模板消息

1. 首先獲得微信的tokenID

package com.txj.bwbd.common.wechat.task;
 
import com.txj.bwbd.constraint.WeixinConstants;
import com.txj.bwbd.utils.WeChatCommonUtil;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Component;
 
@Component
public class WeChatAccessTokenTask {
    Logger logger = LoggerFactory.getLogger(WeChatAccessTokenTask.class);
 
    @Autowired
    private WeChatCommonUtil weChatCommonUtil;

    public static String token;
 
    // 第一次延遲1秒執行，當執行完后7100秒再執行
    @Scheduled(initialDelay = 1000, fixedDelay = 7100*1000 )
//    @Scheduled(initialDelay = 1000, fixedDelay = 7100*1000 )
    public void WeChatAccessToken(){
        try {
            token = weChatCommonUtil.getToken(WeixinConstants.APPID, WeixinConstants.APPSECRET).getAccess_token();
            logger.info("獲取到的微信access_token為"+token);
        } catch (Exception e) {
            logger.error("獲取微信access_toke出錯，信息如下");
            e.printStackTrace();
        }
    }
 
}

package com.txj.bwbd.utils;
 
import cn.hutool.http.HttpUtil;
import com.alibaba.fastjson.JSONObject;
import com.txj.bwbd.common.wechat.entity.AccessToken;
import com.txj.bwbd.constraint.WeixinConstants;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.stereotype.Component;
 
@Component
public class WeChatCommonUtil {

    Logger logger = LoggerFactory.getLogger(WeChatCommonUtil.class);

    // 獲取access_token的接口地址（GET） 限2000（次/天）
    private static String url = WeixinConstants.ACCESS_TOKEN_URL;
 
    public AccessToken getToken(String appid, String appsecret){

        AccessToken token;
        //訪問微信服務器的地址
        String requestUrl=url.replace("APPID", appid).replace("APPSECRET", appsecret);
        //HttpRequestUtil httpRequestUtil=new HttpRequestUtil();
        //創建一個json對象
        String responseStr = HttpUtil.get(requestUrl);
        System.out.println("獲取到的String格式的Response為:"+responseStr);
        //判斷返回字符串是否為空
        if (responseStr != null) {
            token = JSONObject.parseObject(responseStr, AccessToken.class);
        } else {
            token = null;
            // 獲取token失敗
            logger.error("獲取token失敗 errcode:{} errmsg:{}");
        }
        return token;
    }
}

2.組裝微信模板消息訪問參數 調用微信發送模板消息接口

    /**
     * post請求,發送消息
     */
    @RequestMapping(value = "/sendTemplateMessage", method = RequestMethod.POST)
    public String sendTemplateMessage() {
        WeChatTemplate weChatTemplate = new WeChatTemplate();
        weChatTemplate.setTouser("o_Fm8s4563xOZfB05FYpS2IJmRHI");
        weChatTemplate.setTemplate_id("TVNSDJdRNWEHQLMdLWWUcw-6gadxI1tBNeNaK0x40RE");
        Map<String, TemplateData> dataMap = new HashMap<>();
        dataMap.put("first", new TemplateData("這是第一", "#173177"));
        dataMap.put("keynote1", new TemplateData("這是第一", "#173177"));
        dataMap.put("keynote2", new TemplateData("這是第一", "#173177"));
        dataMap.put("keynote3", new TemplateData("這是第一", "#173177"));
        dataMap.put("remark", new TemplateData("這是第一", "#173177"));
        weChatTemplate.setData(dataMap);

        WeixinResponse weixinResponse = templateMessageService
                .sendTemplateMessage(WeChatAccessTokenTask.token, weChatTemplate);

        return "success";
    }

package com.txj.bwbd.common.wechat.service;

import com.txj.bwbd.common.wechat.entity.WeChatTemplate;
import com.txj.bwbd.common.wechat.entity.WeixinResponse;

public interface TemplateMessageService {

    WeixinResponse sendTemplateMessage(String accessToken, WeChatTemplate wechatTemplate);

}

package com.txj.bwbd.common.wechat.service.impl;

import com.txj.bwbd.common.wechat.entity.WeChatTemplate;
import com.txj.bwbd.common.wechat.entity.WeixinResponse;
import com.txj.bwbd.common.wechat.service.TemplateMessageService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.web.client.RestTemplate;

import java.util.HashMap;

@Service
public class TemplateMessageServiceImpl implements TemplateMessageService {


    private RestTemplate restTemplate = new RestTemplate();

    private String serviceHost = "https://api.weixin.qq.com";

    @Override
    public WeixinResponse sendTemplateMessage(String accessToken, WeChatTemplate weChatTemplate) {
        WeixinResponse weixinResponse = null;
        String url = new StringBuffer(serviceHost).append("/cgi-bin/message/template/send?access_token=")
                .append(accessToken).toString();
        weixinResponse = restTemplate.postForObject(url, weChatTemplate, WeixinResponse.class, new HashMap<String, String>());
        return weixinResponse;
    }

}

使用到的實體對象：

package com.txj.bwbd.common.wechat.entity;

import lombok.Data;
import lombok.NoArgsConstructor;

@Data
@NoArgsConstructor
public class TemplateData {

    private String value;
    private String color;

    public TemplateData(String value, String color) {
        this.value = value;
        this.color = color;
    }
}

package com.txj.bwbd.common.wechat.entity;

import lombok.Data;

import java.util.Map;

@Data
public class WeChatTemplate {

    private String touser;

    private String template_id;

    private String url;

    private Map<String, TemplateData> data;
    
}

package com.txj.bwbd.common.wechat.entity;

import lombok.Data;

@Data
public class WeixinResponse {
    private String msgid;
    private int errcode;
    private String errmsg;

    @Override
    public String toString() {
        StringBuffer buf = new StringBuffer("WeixinResponse[msgid=");
        buf.append(msgid)
                .append(",errcode=").append(errcode)
                .append(",errmsg=").append(errmsg)
                .append("]");
        return buf.toString();
    }

}
