本功能可实现与其他 ORM 使用一套 Attribute,避免维护两份实体特性的烦恼:
v1.4.0+ 已自动识别 EFCore 实体特性 Key/Required/NotMapped/MaxLength/StringLength/DatabaseGenerated/Table/Column
fsql.Aop.ConfigEntity += (s, e) => {
var attr = e.EntityType.GetCustomAttributes(typeof(MyTableAttribute), false).FirstOrDefault() as MyTableAttribute;
if (attr != null)
e.ModifyResult.Name = attr.Name; //表名
};
fsql.Aop.ConfigEntityProperty += (s, e) => {
var attr = e.Property.GetCustomAttributes(typeof(MyColumnAttribute), false).FirstOrDefault() as MyColumnAttribute;
if (attr != null)
e.ModifyResult.Name = attr.Name; //字段名
};
[MyTable("xxx")]
class YourEntity {
[MyColumn("id")]
public int pkid { get; set; }
}
class MyTableAttribute : Attribute {
public string Name { get; }
public MyTableAttribute(string name)
{
this.Name = name;
}
}
class MyColumnAttribute : Attribute {
public string Name { get; }
public MyColumnAttribute(string name)
{
this.Name = name;
}
}
