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
<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: wxc67a533f22dc2f9c appsecret: <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; @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) { 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; @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<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; @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://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
