保存方法中的entityName参数是什么? [英] What is entityName parameter in save method?
问题描述
我已经开始学习Hibernate并有一个基本问题。
$ b $ <<> code> save(String entityName,Object object)和 save( Object对象)
在 org.hibernate.Session
类中。
基本上我想知道这个重载方法中的 entityName
参数是什么。
我试图看看这个API,但并没有从中收集很多。
这是一个合乎逻辑的名字一个旨在匹配映射文件中相同实体名称的实体。它默认为当前实体的类名称,但如果您提供自己的值,则可以使用具有多个不同映射文件的相同类。

What is the difference between save(String entityName, Object object)
and save(Object object)
in the org.hibernate.Session
class.
Basically I want to know what the entityName
parameter is in this overloaded method.
I tried to look at the API but didn't glean much from there.
It's a logical name for an entity intended to match the same entity-name in a mapping file. It defaults to the class name for the current entity, but if you provide your own value, then you can use the same class with multiple different mapping files.
See http://www.martinahrer.at/2008/04/09/55/ and http://docs.jboss.org/hibernate/orm/3.3/reference/en/html/mapping.html and http://docs.jboss.org/hibernate/orm/3.3/reference/en/html/persistent-classes.html#persistent-classes-dynamicmodels and http://docs.jboss.org/hibernate/orm/3.3/reference/en/html/xml.html (search for "entity-name" in each case).
