#### 1. 调起微信支付的域名要和微信支付配置的一致,导致无法本地测试 ####

#### 解决方案： 修改本地host文件将配置的域名指向本机, 手机wifi使用本机代理上网。 ####

### [IJPay-All文档地址][IJPay-All] ###

#### 1. maven中引入开发包 ####

<dependency>
        <groupId>com.github.javen205</groupId>
        <artifactId>IJPay-WxPay</artifactId>
        <version>2.4.0</version>
    </dependency>

#### 2. 创建请求需要的参数类。配置信息在application中 ####

import lombok.Data;
    import org.springframework.beans.factory.annotation.Value;
    import org.springframework.context.annotation.Configuration;
    
    @Data
    @Configuration
    public class WxPayProperties { 
        /** * 设置微信公众号或者小程序，h5等的appid. */
        @Value("${wx.pay.appId}")
        private String appId;
    
        /** * 微信支付商户号. */
        @Value("${wx.pay.mchId}")
        private String mchId;
    
        /** * 微信支付商户密钥. */
        @Value("${wx.pay.mchKey}")
        private String mchKey;
    
        /** * 异步回调地址 */
        @Value("${wx.pay.notifyUrl}")
        private String notifyUrl;
    }

##### application配置文件 如下 #####

wx:
      pay:
        appId: wx123223342341 # appid
        mchId: 123423123 # 商户号
        mchKey: U6gG1CqAqwedrfgfffrvfXFBokr # 秘钥 微信商户平台(pay.weixin.qq.com)-->账户设置-->API安全-->密钥设置
        notifyUrl: http://169b91h550.imwork.net:35084/wx/wxPayNotice #可以被外网访问的接口

#### 3. 封装JsApi支付工具 ####
