需求
通过调京东财务余额接口，在项目中显示京东方的财务余额。
思路
思路如下：
- 熟悉京东接口文档
- 通过apifox来测试接口是否能成功获取数据
- 去nacos写好相应配置文件
- 开发
实现
配置JDConfigProperties
**
* @Description： 京东分配给分销商的参数
*/
@RefreshScope
@Configuration
@ConfigurationProperties(prefix = "jd.openapi")
@Setter
@Getter
public class JDConfigProperties {
private String grantType;//获取accesstoken接口的固定值，access_token
private String clientId;//对接账号
private String clientSecret;//由京东分配
private String userName;//京东用户名
private String password;//京东的密码
private String url;//对接京东的接口地址,配置示例：https://bizapi.jd.com
//接口地址
private String accessToken;//获取AccessToken接口,配置示例：/oauth2/access_token
private String refreshToken;//刷新AccessToken接口,配置示例：/oauth2/refreshToken
