1.申请测试号，并记录appID和appsecret

2.关注测试号

3.添加消息模板

{{topic.DATA}} 用户名： {{user.DATA}} 单车编号：{{car.DATA}} 锁定时间：{{date.DATA}} {{remark.DATA}}

微信接口配置和代码

1.添加微信配置文件

import org.springframework.boot.context.properties.ConfigurationProperties;import org.springframework.context.annotation.Configuration;@Configuration@ConfigurationProperties(prefix = "wechat")public class WechatConf { // 获取accessToken的接口 public static final String GET_TOKEN_URL = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=%s&secret=%s"; // 发送消息的接口 public static final String PUSH_MESSAGE_URL = "https://api.weixin.qq.com/cgi-bin/message/template/send?access_token=%s"; private String appId; private String appsecret; // 发送消息的接口的访问凭证 private String accessToken; public String getAppId() { return appId; } public void setAppId(String appId) { this.appId = appId; } public String getAppsecret() { return appsecret; } public void setAppsecret(String appsecret) { this.appsecret = appsecret; } public String getAccessToken() { return accessToken; } public void setAccessToken(String accessToken) { this.accessToken = accessToken; }}

这里@ConfigurationProperties(prefix = "wechat")注解会报黄，需要导入依赖

<dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-configuration-processor</artifactId><optional>true</optional></dependency>

2.填写配置文件application.yml

以下两个值会被注入到WechatConf 中

wechat:app-id: wxc67a533f22dc2f9cappsecret: <your appsecret>

3.注入发送Http请求的对象

import org.springframework.context.annotation.Bean;import org.springframework.context.annotation.Configuration;import org.springframework.web.client.RestTemplate;@Configurationpublic class RestConf {@Beanpublic RestTemplate getRestTemplate() {return new RestTemplate();}}

4.后台调用微信接口凭证AccessToken的封装类

import com.fasterxml.jackson.annotation.JsonProperty;public class AccessToken {@JsonProperty("access_token")private String accessToken;@JsonProperty("expires_in")private Long expiresIn;public String getAccessToken() {return accessToken;}public void setAccessToken(String accessToken) {this.accessToken = accessToken;}public Long getExpiresIn() {return expiresIn;}public void setExpiresIn(Long expiresIn) {this.expiresIn = expiresIn;}}

5.使用定时任务获取后台访问微信接口的凭证AccessToken

注意：需在启动类上添加开启定时任务的注解@EnableScheduling

import org.springframework.beans.factory.annotation.Autowired;import org.springframework.scheduling.annotation.Scheduled;import org.springframework.stereotype.Component;import org.springframework.web.client.RestTemplate;import com.thy.common.AccessToken;import com.thy.config.WechatConf;@Componentpublic class MessageTask {@Autowiredprivate RestTemplate restTemplate;@Autowiredprivate WechatConf wechatConf;/*** initialDelay: 初始化2s后执行第一次* fixedDelay:微信默认Token过期时间为7200s,这里定时7100s执行一次定时任务*/@Scheduled(initialDelay = 2000, fixedDelay = 7100 * 1000)public void refreshToken() {// 请求方式: GET// URL：https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=APPID&secret=APPSECRET// 发起一个get请求，返回的数据json文本，使用json工具将json文本直接转化为Class<?>AccessToken accessToken = restTemplate.getForObject(String.format(WechatConf.GET_TOKEN_URL, wechatConf.getAppId(), wechatConf.getAppsecret()),AccessToken.class);// 将获取的accessToken注入wechatConfwechatConf.setAccessToken(accessToken.getAccessToken());}}

6.发送消息接口的请求参数的封装类

import java.util.HashMap;import java.util.Map;import com.fasterxml.jackson.annotation.JsonProperty;public class MessageTemplate {@JsonProperty("touser")private String toUser;@JsonProperty("template_id")private String templateId;private String url;private Map<String,String> miniprogram;private Map<String, Map<String, String>> data = new HashMap<>();public static Map<String, String> initData(String value, String color) {HashMap<String, String> data = new HashMap<String, String>();data.put("value", value);data.put("color", color);return data;}public String getToUser() {return toUser;}public void setToUser(String toUser) {this.toUser = toUser;}public String getTemplateId() {return templateId;}public void setTemplateId(String templateId) {this.templateId = templateId;}public String getUrl() {return url;}public void setUrl(String url) {this.url = url;}public Map<String, String> getMiniprogram() {return miniprogram;}public void setMiniprogram(Map<String, String> miniprogram) {this.miniprogram = miniprogram;}public Map<String, Map<String, String>> getData() {return data;}public void setData(Map<String, Map<String, String>> data) {this.data = data;}}

7.发送消息接口的返回值的封装类

public class Result {private Integer errcode;private String errmsg;private Long msgid;public Integer getErrcode() {return errcode;}public void setErrcode(Integer errcode) {this.errcode = errcode;}public String getErrmsg() {return errmsg;}public void setErrmsg(String errmsg) {this.errmsg = errmsg;}public Long getMsgid() {return msgid;}public void setMsgid(Long msgid) {this.msgid = msgid;}}

8.消息发送接口

import java.text.SimpleDateFormat;import java.util.Date;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.web.bind.annotation.RequestBody;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RestController;import org.springframework.web.client.RestTemplate;import com.thy.common.MessageTemplate;import com.thy.common.Result;import com.thy.config.WechatConf;import com.thy.pojo.UserCarInfo;@RestControllerpublic class MessageController {@Autowiredprivate RestTemplate restTemplate;@Autowiredprivate WechatConf wechatConf;@RequestMapping("/sendMessage")public Object sendMessage(@RequestBody UserCarInfo userCarInfo) {MessageTemplate messageTemplate = new MessageTemplate();// 设置模板idmessageTemplate.setTemplateId("othsG1ZD5w9ywTGyV6XCECnY1Q1oAIY5e-NvF94fzAI");// 设置接收用户openIdmessageTemplate.setToUser("oUbk_1bVlUGqhMzQHMC_jbkysMgY");//点击详情跳转的地址messageTemplate.setUrl("http://www.baidu.com");//设置模板dada参数messageTemplate.getData().put("topic", MessageTemplate.initData("您的单车已经锁定成功，骑行请注意安全！\n", ""));messageTemplate.getData().put("user", MessageTemplate.initData(userCarInfo.getUserName(), "#0000EE"));messageTemplate.getData().put("car", MessageTemplate.initData(userCarInfo.getCarSn(), "#00CD00"));SimpleDateFormat simpleDateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");messageTemplate.getData().put("date", MessageTemplate.initData(simpleDateFormat.format(new Date())+"\n", ""));messageTemplate.getData().put("remark", MessageTemplate.initData("点击详情可查看您的租车信息", ""));//调用微信接口，发送模板消息Result result = restTemplate.postForObject(String.format(WechatConf.PUSH_MESSAGE_URL, wechatConf.getAccessToken()),messageTemplate, Result.class);return result;}}

测试

1.运行项目，发送请求

2.接收到微信提醒消息
