SpringBoot集成ShardingSphere（自动配置）

接上一篇，介绍下SpringBoot集成ShardingSphere，基于sharding-jdbc-spring-boot-starter依赖编写配置文件实现自动配置的集成方法，这种方法的优点是简单，缺点是不够灵活。

• 新建项目并导入依赖

    4.0.0
    
        org.springframework.boot
        spring-boot-starter-parent

• 其他步骤基本与上一篇类似，不再赘述，可以查看上篇：https://blog.csdn.net/hyc2zbj/article/details/94005745
• 分片规则配置

#actuator端口
management.server.port=9001
#开放所有页面节点  默认只开启了health、info两个节点
management.endpoints.web.exposure.include=*

mybatis.configuration.map-underscore-to-camel-case=true
mybatis.type-aliases-package=com.hyc.entity
mybatis.mapper-locations=classpath:mappers/*.xml

以上就配置完成了，测试结果和上一篇一样
