Java微信小程序发送服务通知
小程序：
wxml:
wxss:
.modelButton{
margin-top:50%;
width: 50%;
}js前端发送模板消息:
注意：每个小程序的openid都是不一样的，这里使用的是我的小程序的openid，应替换为自己小程序的openid。
关于解密openid参考我的另一篇博客：https://blog.csdn.net/LONG_Yi_1994/article/details/82977603
testSubmit: function(e) {
console.log(e);

}java代码后台发送模板消息：
后端发送模板消息需要获取前端表单提交的formid
controller：
@GetMapping("/publishModelMessage")
public String publishModelMessage(@RequestParam(required = false) String formId,@RequestParam(required = false) String openId,HttpServletResponse response){
openId = "oK_7b4mGyt6L9DRXWINxjEeCb_no";
Token token = CommonUtil.getToken("你的小程序appid","你的小程序密钥");
System.out.println(token.getAccessToken());
WxMssVo wxMssVo = new WxMssVo();
wxMssVo.setTemplate_id("PZ-QULr4atCAgBacoMjh09u0bAVA_St-lNCp5jV7Pcs");
wxMssVo.setTouser(openId);
wxMssVo.setPage("pages/index/index");
wxMssVo.setRequest_url("https://api.weixin.qq.com/cgi-bin/message/wxopen/template/send?access_token=" + token.getAccessToken());
wxMssVo.setForm_id(formId);
List list = new ArrayList<>();
list.add(new TemplateData("通知","#ffffff"));
list.add(new TemplateData("李银龙","#ffffff"));
list.add(new TemplateData("发布成功","#ffffff"));
list.add(new TemplateData(new Date().toString(),"#ffffff"));

}Token类:

//接口访问凭证
private String accessToken;

public void setExpiresIn(int expiresIn) {
this.expiresIn = expiresIn;
}
}模板消息请求参数封装类WxMssVo ：
public class WxMssVo {
private String touser;
private String template_id;
private String page;
private String form_id;
private String access_token;
private String request_url;
private List params = new ArrayList<>();
} 模板消息详细参数封装TemplateData ：
public class TemplateData {
private String key;
private String value;
private String color;
public TemplateData(String value, String color) {
this.value = value;
this.color = color;
}
