配置@DS 报 com.alibaba.druid.pool.DruidDataSource

这个报错通常是因为缺少 Druid 数据源的依赖，你需要在项目的 pom.xml 文件中添加以下依赖：

<dependency>
    <groupId>com.alibaba</groupId>
    <artifactId>druid</artifactId>
    <version>1.1.10</version>
</dependency>

同时，你需要检查一下你的配置文件中是否正确配置了 Druid 数据源。你可以参考以下配置：

spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=utf-8&useSSL=false
spring.datasource.username=root
spring.datasource.password=root
