之前的项目中用到了maven，而且是web项目（但不是标准的ssh架构），趁着假期，重用南哥的pom文件，自己也试试用maven构建web项目,搭建完整的ssh开发框架。
工具准备：jdk，eclipse，maven
Eclipse 插件：Hibernate Tools
（以上工具软件请请自行Google下载安装）
当然，构建过程需要畅通的网络，以确保maven能顺利下载依赖包。
第一步，在eclipse新建Maven项目，
New->Maven Project；
两个next之后选择maven-archetype-webapp 架构类型；
Next,然后设置好Group Id，Artifact Id，等信息，之后点击Finish。
至此，web项目已经搭建好。
在src/main目录下建立java和test代码文件夹，
下面进行maven依赖配置和ssh配置
下面只需要配置项目根目录下的pom.xml文件，配置ssh框架的各种依赖jar包，并设定Java版本，Maven默认是1.5
pom.xml

更改pom.xml之后，在项目右键，Maven -> Update Project,配置已更新，ssh各种依赖包已导入。
下面是各种配置文件，web.xml在webapp目录下的WEB-INF下，spring配置文件spring-config.xml我把它放在了web.xml同级的spring配置文件夹下，可自行更改，只需在web.xml中指定即可。
在src/main/resources/下放置hibernate 配置文件，struts 2 配置文件，log4j等一系列配置
web.xml

spring-config.xml，其中包含了对hibernate的配置

至此，基于Maven的ssh 架构web开发环境就搭建完成了。
一些收获，做过一些项目后，重用已有的架构和相应的组件会减少造轮子的过程，省时省力-.-
下面附上通过Hibernate Tools来自动生成关系数据库里对应的实体类和相应的映射文件（映射文件的位置可在spring-config.xml中配置）
首先打开Hibernate Tools视图，新建配置
Hibernate configured connection 点击New，新建数据库连接，首先选择数据库类型
next，配置数据库连接信息
点击右上角，添加数据库驱动jar包。
至此，数据库连接配置完毕。
下面为项目生成实体类和相应的配置文件，
在Hibernate Tools视图下运行Hibernate Code 生成配置
配置基本信息
可以在reveng.xml配置映射那些表，不设置则默认全部映射。
然后在Exporters里配置生成哪些文件
点击 Run就可以在指定的输出包里看到相应的实体类和对应的Hibernate映射文件。
That‘s all. Good Luck. - - !
