spring+hibernate 两种整合方式配置文件的方法

时间:2022-08-25 12:19:22

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 "*"
