<parent>
  <groupId>org.springframework.boot</groupId>
  <artifactId>spring-boot-starter-parent</artifactId>

  <relativePath/>
</parent>

<mybatisPlus.version>3.4.0</mybatisPlus.version>
<shardingsphere.version>4.1.1</shardingsphere.version>

<!-- 不能使用druid-spring-boot-starter，会导致：Property 'sqlSessionFactory' or 'sqlSessionTemplate' are required -->

            <artifactId>lombok</artifactId>
            <scope>provided</scope>
        </dependency>

数据源连接配置：

#com.alibaba.druid.pool.DruidDataSource
#DruidDataSource需要引入druid的Jar包，使用：url
#com.zaxxer.hikari.HikariDataSource
#HikariDataSource要使用：jdbc-url
spring.shardingsphere.datasource.ss1.type=com.alibaba.druid.pool.DruidDataSource
spring.shardingsphere.datasource.ss1.driver-class-name=com.mysql.cj.jdbc.Driver
spring.shardingsphere.datasource.ss1.url=jdbc:mysql://localhost:3306/ss1?useUnicode=true&characterEncoding=utf-8&useSSL=false&serverTimezone=GMT%2B8&pinGlobalTxToPhysicalConnection=true&autoReconnect=true&nullNamePatternMatchesAll=true
spring.shardingsphere.datasource.ss1.username=root
spring.shardingsphere.datasource.ss1.password=root

注意：

不能使用：druid-spring-boot-starter，不然会导致下面的问题：java.lang.IllegalArgumentException: Property 'sqlSessionFactory' or 'sqlSessionTemplate' are required

Caused by: java.lang.IllegalArgumentException: Property 'sqlSessionFactory' or 'sqlSessionTemplate' are required
