使用shardingsphere 进行分表操作

shardingsphere v4.0.0 会存在分页BUG 报错int类型不能转为Long类型问题

需要升级到v4.1.1

v4.0.0的配置为

复制代码

#数据配置
spring.shardingsphere.datasource.names: m1
spring.shardingsphere.datasource.m1.type: com.zaxxer.hikari.HikariDataSource
spring.shardingsphere.datasource.m1.driver‐class‐name:  com.mysql.jdbc.Driver
spring.shardingsphere.datasource.m1.jdbc-url: jdbc:mysql://IP:3306/库名?useUnicode=true&characterEncoding=UTF-8&serverTimezone=Asia/Shanghai&useSSL=false
spring.shardingsphere.datasource.m1.username: 用户名
spring.shardingsphere.datasource.m1.password: 密码

#分表依据字段设置
spring.shardingsphere.sharding.tables.表名.table-strategy.standard.sharding-column:  create_time
spring.shardingsphere.sharding.tables.表名.table-strategy.standard.precise-algorithm-class-name: 分表策略类名

升级后配置文件中必须含有

复制代码

spring.shardingsphere.sharding.tables.cn_call_log_execute_time.actual-data-nodes

否则启动会报错
