Spring命名空间配置

注意事项

行表达式标识符可以使用${…}或$->{…}，但前者与Spring本身的属性文件占位符冲突，因此在Spring环境中使用行表达式标识符建议使用$->{…}。

配置项说明

分库分表

命名空间：http://shardingsphere.io/schema/shardingsphere/sharding/sharding.xsd

<sharding:data-source />

名称类型说明
id属性Spring Bean Id
sharding-rule标签数据分片配置规则
config-map (?)标签用户自定义配置
props (?)标签属性配置

<sharding:sharding-rule />

名称类型说明
data-source-names属性数据源Bean列表，多个Bean以逗号分隔
table-rules标签表分片规则配置对象
binding-table-rules (?)标签绑定表规则列表
broadcast-table-rules (?)标签广播表规则列表
default-data-source-name (?)属性未配置分片规则的表将通过默认数据源定位
default-database-strategy-ref (?)属性默认数据库分片策略，对应<sharding:xxx-strategy>中的策略Id，缺省表示不分库
default-table-strategy-ref (?)属性默认表分片策略，对应<sharding:xxx-strategy>中的策略Id，缺省表示不分表
default-key-generator-ref (?)属性默认自增列值生成器引用，缺省使用io.shardingsphere.core.keygen.DefaultKeyGenerator。该类需实现KeyGenerator接口

<sharding:table-rules />

名称类型说明
table-rule (+)标签表分片规则配置对象

<sharding:table-rule />

名称类型说明
