为什么不推荐HibernateDaoSupport？ [英] Why is HibernateDaoSupport not recommended?

问题描述

最近我一直在用Hibernate 3.5和Spring 3做一些工作，我对Hibernate很熟悉，并且认为Spring中的 HibernateDaoSupport 类使它变得简单和容易然而，在搜索一个不相关的问题时，我看到有人提到 HibernateDaoSupport 不是使用Spring和Hibernate的最佳方式。任何人都可以点亮：

• 为什么不推荐？


• 什么是最好的（或至少被接受）的方式来集成Hibernate和Spring？
  
  

  解决方案

  使用<$不建议使用HibernateDaoSupport / HibernateTemplate ，因为它不必要地
  将您的代码绑定到Spring类。

  
  
  

  使用这些类对于旧版本的Hibernate来说是不可避免的，以便集成对Spring管理的事务的支持。然而，由于Hibernate 3.0 .1你不再需要它 - 你可以在使用Spring管理的事务时使用普通的Hibernate API编写代码。所有你需要的是配置Spring事务支持，当你需要工作时，注入 SessionFactory 并调用 getCurrentSession（）与会议。
  
  

  HibernateTemplate 的另一个好处是异常转换。如果没有 HibernateTemplate ，可以使用 @Repository 注释来实现相同的功能，如Gareth Davis的答案所示。

I've been doing some work with Hibernate 3.5 and Spring 3 recently, I'm fairly new with Hibernate and thought the HibernateDaoSupport class in Spring made it nice and easy to use Hibernate with my domain classes.

However, while searching for an unrelated question I saw someone mention that the HibernateDaoSupport is not the best way to use Spring and Hibernate. Can anyone shed any light on:

• Why is it not recommended?
• What is the best (or at least the accepted) way to integrate Hibernate and Spring?

解决方案

Using HibernateDaoSupport/HibernateTemplate is not recommended since it unnecessarily ties your code to Spring classes.

Using these classes was inevitable with older versions of Hibernate in order to integrate support of Spring-managed transactions.

However, since Hibernate 3.0.1 you don't need it any more - you can write a code against a plain Hibernate API while using Spring-managed transactions. All you need is to configure Spring transaction support, inject SessionFactory and call getCurrentSession() on it when you need to work with session.

Another benefit of HibernateTemplate is exception translation. Without HibernateTemplate the same functionality can be achieved by using @Repository annotation, as shown in Gareth Davis's answer.
