一、该问题的重现步骤是什么?
1.yml配置如下
rules:
sharding:
#主键生成类型
key-generators:
snowflake:
type: SNOWFLAKE
tables:
#分表代号
blade_notice:
#实际节点名称,格式为 库名$->{0..n1}.表名$->{0..n2}
#blade_notice_$->{1..2} 代表有 blade_notice_1和blade_notice_2两个表
actual-data-nodes: ds1.BLADE_NOTICE_$->{1..2}
#分表策略
table-strategy:
standard:
#分表列名
sharding-column: id
#分表算法名,不可用下划线
sharding-algorithm-name: blade-notice-inline
#主键生成策略
key-generate-strategy:
#主键名
column: id
#策略算法
key-generator-name: snowflake
#分库分表算法
sharding-algorithms:
#分表算法名
blade-notice-inline:
#算法类型
type: INLINE
props:
#算法表达式
#表达式写法非常自由,以下配置仅作为参考
#blade_notice_$->{id % 2 + 1} 代表对id进行取余,根据id的基偶来指向blade_notice_1和blade_notice_2
algorithm-expression: BLADE_NOTICE_$->{id % 2 + 1}
2.查询分页出现异常
