sharding-jdbc具体使用方式

先在pom.xml中引入依赖

<dependency>
    <groupId>org.apache.shardingsphere</groupId>
    <artifactId>sharding-jdbc-spring-boot-starter</artifactId>
    <version>4.0.1</version>
</dependency>

这里用的是sharding-jdbc-spring-boot-starter
需要注意的是,此时druid不能用spring-boot-starter版本的,需要用正常的包:

<dependency>
    <groupId>com.alibaba</groupId>
    <artifactId>druid</artifactId>
    <version>1.1.22</version>
</dependency>

不然启动会报错找不到url
