这篇CFSDN的博客文章spring+hibernate 两种整合方式配置文件的方法由作者收集整理，如果你对这篇文章有兴趣，记得点赞哟.

之前的文章都是讲解springmvc+spring+mybatis 的整合，而很少有springmvc+spring+hibernate 因为工作的需要，最近在使用hibernate 所以下面我们来看看 spring整合hibernate的配置文件，这里只说spring+hibernate 的配置文件而不说springmvc 因为这些是不用变的.

spring整合hibernate 有两种方式 1、注解方式 2、xml方式实现 。

1、注解方式实现:

applicationContext.xml配置文件:

2.xml方式实现 。

两种配置最大的区别就是注解方式不用在写O/R映射配置文件而xml方式实现的要配置O/R映射配置文件 。

注解的这种方式，直接扫描bean包就可以，剩下的对应关系由框架完成 。

而xml配置方式要配置O/R 映射文件并在这里指定文件，如果多的话可以使用通配符 "*" 。
