SpringBoot微信消息接口配置详解

SpringBoot微信消息接口配置详解

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

org.springframework.boot

spring-boot-configuration-processor

true

2.填写配置文件application.yml

以下两个值会被注入到WechatConf 中

wechat:

app-id: wxc67a533f22dc2f9c

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;

@Configuration

public class RestConf {

@Bean

public 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) {

twtVzvlHGGhis.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.schedulinghttp://.annotation.Scheduled;

import org.springframework.stereotype.Component;

import org.springframework.web.client.RestTemplate;

import com.thy.common.AccessToken;

import com.thy.config.WechatConf;

@Component

public class MessageTask {

@Autowired

private RestTemplate restTemplate;

@Autowired

private 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wechatConf

wechatConf.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 miniprogram;

private Map> data = new HashMap<>();

public static Map initData(String value, String color) {

HashMap data = new HashMap();

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 getMiniprogram() {

return miniprogram;

}

public void setMiniprogram(Map miniprogram) {

this.miniprogram = miniprogram;

}

public Map> getData() {

return data;

}

public void setData(Map> 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;

@RestController

public class MessageController {

@Autowired

private RestTemplate restTemplate;

@Autowired

private WechatConf wechatConf;

@RequestMapping("/sendMessage")

public Object sendMessage(@RequestBody UserCarInfo userCarInfo) {

MessageTemplate messageTemplate = new MessageTemplate();

// 设置模板id

messageTemplate.setTemplateId("othsG1ZD5w9ywTGyV6XCECnY1Q1oAIY5e-NvF94fzAI");

// 设置接收用户openId

messageTemplate.setToUser("oUbk_1bVlUGqhMzQHMC_jbkysMgY");

//点击详情跳转的地址

messageTemplate.setUrl("http://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
