shardingjdbc配置文件配置

spring.main.allow-bean-definition-overriding = true
#sharding-jdbc分片規則配置
#數據源  m1可以自己定義
spring.shardingsphere.datasource.names = m1

# 這里的m1就是上面的數據源名稱
spring.shardingsphere.datasource.m1.type = com.alibaba.druid.pool.DruidDataSource
spring.shardingsphere.datasource.m1.driver-class-name = com.mysql.jdbc.Driver
spring.shardingsphere.datasource.m1.url = jdbc:mysql://localhost:3306/test?useUnicode=true
spring.shardingsphere.datasource.m1.username = root
spring.shardingsphere.datasource.m1.password = 85586537

# 指定t_order表的數據分布情況，數據庫的表為t_order_1和t_order_2，配置數據節點 m1.t_order_1,m1.t_order_2
spring.shardingsphere.sharding.tables.t_order.actual-data-nodes = m1.t_order_$->{1..2}

# 指定t_order表的主鍵order_id的生成策略為SNOWFLAKE
spring.shardingsphere.sharding.tables.t_order.key-generator.column=order_id
spring.shardingsphere.sharding.tables.t_order.key-generator.type=SNOWFLAKE

# 指定t_order表的分片策略，分片策略包括分片鍵和分片算法
spring.shardingsphere.sharding.tables.t_order.table-strategy.inline.sharding-column = order_id
spring.shardingsphere.sharding.tables.t_order.table-strategy.inline.algorithm-expression = t_order_$->{order_id % 2 + 1}

# 打開sql輸出日志
spring.shardingsphere.props.sql.show = true

　　

mysql數據庫不用配置
