Spring+SpringMVC+Hibernate+Maven的整合

来源：互联网发布：dreamhost java 编辑：程序博客网时间：2024/05/16 04:29

主要记录对于整合Spring、SpringMVC、Hibernate以及Maven的一个步骤以及相关需要的配置文件，和需要注意的地方。PS：师傅要我整合这个的时候，看了网上很多例子，现在整合一下。

Spring+SpringMVC+Hibernate+Maven的整合主要有以下几步：

创建数据库表，本次使用的是PostgreSQL；
创建Maven工程；
添加项目需要的所有库；
创建包结构；
创建配置applicationContext.xml（配置JavaBean以及数据库连接等信息）以及springmvc.xml（配置视图解析器等信息）；
配置web.xml文件；
具体编码；（后台的Controller、Service、DAO；前台的Views）。

要求安装Java环境，PostgreSQL数据库，Maven、Tomcat，并在Eclipse中配置。

添加项目所需要的库，配置pom.xml
