NHibernate:映射到字段或属性? [英] NHibernate : map to fields or properties?

问题描述

当您创建映射文件时，您是否将属性映射到字段或属性:

When you create your mapping files, do you map your properties to fields or properties :

<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" assembly="Foo" namespace="Foo.Bar" >
  <class name="Foo" table="FOOS" batch-size="100">
    [...]
    <property name="FooProperty1" access="field.camelcase" column="FOO_1" type="string" length="50" />
    <property name="FooProperty2" column="FOO_2" type="string" length="50" />
    [...]
  </class>
</hibernate-mapping>

当然，请解释原因:)

通常，我映射到属性，但映射到字段可以在属性的 getter/setter 中放置一些逻辑".

Usually, I map to properties, but mapping to fields can enable to put some "logic" in the getters/setters of the properties.

映射到字段不好"吗?有最佳实践吗?

Is it "bad" to map to fields ? Is there a best practice ?

推荐答案

我映射到属性.如果我觉得有必要，我会将 SETTER 映射到一个字段.(通常通过access=field.camelcase"之类的方式).

I map to properties. If I find it necessary, I map the SETTER to a field. (usually via something like "access=field.camelcase").

这让我有漂亮的查询，例如from People Where FirstName = 'John'" 而不是from People Where firstName/_firstName"，并且在给我的实体补水时也避免了 setter 逻辑.

This lets me have nice looking Queries, e.g. "from People Where FirstName = 'John'" instead of something like "from People Where firstName/_firstName" and also avoid setter logic when hydrating my entities.
