不需要数据库的服务怎么去掉数据源配置

一、该问题的重现步骤是什么？

1. 创建空项目，只有一个启动文件，没有application配置文件

   @BladeCloudApplication
   public class DemoApplication {
      public static void main(String[] args) {
         BladeApplication.run("demo", DemoApplication.class, args);
      }
   }

2. 修改 pom 文件，增加依赖

blade-common
blade-core-boot

3.

二、你期待的结果是什么？实际看到的又是什么？

期待结果：此服务不需要服务库，不需要配置数据源也要能正常启动；

实际看到：不配置数据源服务启动失败，提示 DataSource  url 错误；

三、你正在使用的是什么产品，什么版本？在什么操作系统上？

bladex3， windows

四、请提供详细的错误堆栈信息，这很重要。
