2.2 服务器配置

编辑服务器信息

1. Url 是之后的服务器信息

   因为需要外网能访问，所以需要使用到内网穿透，可以使用natapp来映射natapp参考文章

2. token随便填写

提交需要等到服务启动完成后

3. 集成使用

3.1 依赖

<!--微信公众号工具-->
<dependency>
    <groupId>com.github.binarywang</groupId>
    <artifactId>weixin-java-mp</artifactId>
    <version>4.0.0</version>
</dependency>

        return wxMpMessageRouter;
    }
}

3.4 WxMpProperties

package com.zszdevelop.wxdemo.config;

import lombok.Data;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;

@Data
@Component
@ConfigurationProperties(prefix = "wx.mp")
public class WxMpProperties {

    String appId;

    String token;
    String aesKey;

}

3.5 application.yml

server:
  port: 8089

wx:
  mp:
    appId: wx41f3d2xxxxx
    secret: 54d21f829e33b0df7xxxx
    token: yxxx
    aesKey: KFDg3J0YPQoY5tGTwoO4OEZu2xxxxx

3.6 运行测试

1. 将项目运行起来

2. 确认服务器配置

3. 接收到微信发来的认证信息
