最近一直在找工作,面试的时候提到他们公司的项目使用ssh(spring springmvc hibernate)做的,回想起来好像还真没有做过这个整合。其实想了一下,也挺简单的,就是传统ssh的webmvc层面struts2替换为springmvc,或者说是ssm的mybatis替换为hibernate作为orm框架。反正都是spring管理,挺简单的。
做了一个demo学习一下,顺便回顾一下hibernate。
思路:springmvc天然集成spring,难度不大,主要是集成hibernate。
具体版本信息:
spring:4.3.7.RELEASE
hibernate:5.2.11.Final
一,spring+springmvc:天然集成,具体需要配置的有:
- 添加依赖
- 配置加载spring容器和springmvc的dispatcherServlet
- 配置applicationContext.xml文件
- 配置springmvc.xml
- 配置resource资源文件
二,spring+hibernate
采用hbm映射文件的方式,具体需要的配置包含 - 添加依赖
- 配置数据源(druid)
- 配置sqlsessionFactory
- 配置一个HibernateTemplate
4.配置事务相关
