程序包 org.dromara.autotable.core.strategy.mysql

类 MysqlStrategy

java.lang.Object

org.dromara.autotable.core.strategy.mysql.MysqlStrategy

所有已实现的接口:

IStrategy<MysqlTableMetadata,MysqlCompareTableInfo>

public class MysqlStrategy
extends Object
implements IStrategy<MysqlTableMetadata,MysqlCompareTableInfo>

项目启动时自动扫描配置的目录中的model，根据配置的规则自动创建或更新表 该逻辑只适用于mysql，其他数据库尚且需要另外扩展，因为sql的语法不同
