sharding-jdbc springboot demo

spring yaml配置中：

（1）需将`${product_id % 3} 替换成$->{product_id % 3}`，否则启动失败，将${...}当做无法解析的属性

（2）spring.shardingsphere.rules.sharding.key-generators,spring.shardingsphere.rules.sharding.sharding-algorithms
其下的name需将`下划线替换成中横线`，否则通过PropertyUtil.containPropertyPrefix(environment, propsPrefix)无法获取到属性 

（3）使用mybatis-plus需在实体entity对象中PK列上添加@TableId(type=IdType.NONE)属性，否则通过sharding-jdbc生成的ID无法赋值给对应属性
