数据库交互实体类及相关特性使用说明

  • 2.使用相关特性,对实体类属性进行设置
  • TableAttribute:数据库表名,多表连接时为对应的连接关系
  • KeyAttribute:数据库主键标识
  • DatabaseGeneratedAttribute:数据库生成特性,标识自增、计算列等(插入时会忽略此字段)
  • NotMappedAttribute:数据库中不存在此字段时,使用此特性忽略该字段
  • ColumnAttribute:实体类别名映射特性,标注数据库实际字段名

默认约定

  • 1.若不使用特性,则程序按默认约定进行解析
  • 2.表名称为类名,或者类名去掉Entity字符串
  • 3.主键为Id字段,或者Id结尾的字段
