1.水平分表 

# shardingjdbc分片策略
# 配置数据源，给数据源起名称
spring.shardingsphere.datasource.names=m1

# 一个实体类对应两张表，覆盖
spring.main.allow-bean-definition-overriding=true

#配置数据源具体内容，包含连接池，驱动，地址，用户名和密码
spring.shardingsphere.datasource.m1.type=com.alibaba.druid.pool.DruidDataSource
spring.shardingsphere.datasource.m1.driver-class-name=com.mysql.cj.jdbc.Driver
spring.shardingsphere.datasource.m1.url=jdbc:mysql://localhost:3306/test?serverTimezone=GMT%2B8
spring.shardingsphere.datasource.m1.username=root
spring.shardingsphere.datasource.m1.password=root

#指定course表分布情况，配置表在哪个数据库里面，表名称都是什么  m1.course_1 , m1.course_2
spring.shardingsphere.sharding.tables.course.actual-data-nodes=m1.course$->{1..2}

# 指定course表里面主键cid 生成策略  SNOWFLAKE
spring.shardingsphere.sharding.tables.course.key-generator.column=cid
spring.shardingsphere.sharding.tables.course.key-generator.type=SNOWFLAKE

# 指定分片策略  约定cid值偶数添加到course1表，如果cid是奇数添加到course2表
spring.shardingsphere.sharding.tables.course.table-strategy.inline.sharding-column=cid
spring.shardingsphere.sharding.tables.course.table-strategy.inline.algorithm-expression=course$->{cid % 2 + 1}

# 打开sql输出日志
spring.shardingsphere.props.sql.show=true

#指定数据库分布情况，数据库里面表分布情况
# m1  m2    course1 course2
spring.shardingsphere.sharding.tables.course.actual-data-nodes=m$>{1..2}.course$->{1..2}

# 指定course表里面主键cid 生成策略  SNOWFLAKE
spring.shardingsphere.sharding.tables.course.key-generator.column=cid
spring.shardingsphere.sharding.tables.course.key-generator.type=SNOWFLAKE

spring.shardingsphere.sharding.tables.course.table-strategy.inline.sharding-column=cid
spring.shardingsphere.sharding.tables.course.table-strategy.inline.algorithm-expression=course$->{cid % 2 + 1}

# 指定数据库分片策略 约定user_id是偶数添加m1，是奇数添加m2
#spring.shardingsphere.sharding.default-database-strategy.inline.sharding-column=user_id
#spring.shardingsphere.sharding.default-database-strategy.inline.algorithm-expression=m$->{user_id % 2 + 1}

#分库策略
