查询的json ，前端不传递 @schema时，是否可以默认 是application.yml 配置数据源的schema呢。

问题描述

查询的json中配置了 @Datasource ,但没有配置@Schema时。能不能 就默认是后台配置数据源时带的schema呢？

查询报错，如下图

如果在查询的json 中传递了 @Schema , 可以查询出正确的结果，如下图：

但我期望，查询json中但没有配置@Schema时，能不能 就默认是后台配置数据源时带的schema （base_nn4）呢?

DemoSQLConfig 重写 getSchema，判断 getDatasource 的值不为空就 return null，或者登录接口 defaults 里传 "@Schema":""

我的错。忘记在 java 代码中增加数据源。
