以前做过一个 关于Spring MVC + Spring + MyBatis（简称 SSM）的一个CRUD的完整Web 演示例子。周末利用空闲时间做了个 关于Struts2+Spring+MyBatis+Maven 的 web版CRUD的整合完整版演示例子。在功能上和上次做的 Spring MVC + Spring + MyBatis 实例相似，基本的，记得上次的那个实例好像没有分页，所以我这次在做这个Demo的时候，已经把分页做上了。如果你也是刚好学习这几个框架的新手，或许我做的这个例子对你刚好有所帮助哦！这次的这个实例个人感觉比较粗糙，所以我会在后期做些微动的修改，比如 优化代码注释，优化代码（删除一些冗余的代码片段；在MyBatis的映射文件中有部分方法是我以前做的实验例子；）等。
下面我就将代码的运行效果图贴出来：
演示工程的目录结构
项目的首页
查询出的数据列表
新增数据的界面
编辑数据的界面
分页中的上一页
分页中的下一页
好了，以上一项目运行时截图。
这个整合项目使用Eclilpse中开发，使用框架 Struts2、Spring、MyBatis、Maven框架，数据库使用的是MySQL。主要功能：增、删、改、查。采用的数据库连接池是来自阿里巴巴的Druid。下面贴出项目 中的部分代码以供大家参考。

以上就是几个关键位置的代码，我全部贴出来了（其他代码我就不全部贴出来了，感兴趣的可以下载哟~）。至于配置文件什么的，由于时间原因没有贴出。如果大家要是感兴趣的话，可以下载我的这个演示项目包，里面的东西都齐全着，以Maven项目形式导入到Eclipse里面，然后部署到服务器上面就可以运行。数据库就是里面的那个.sql文件。建个库然后将数据导入就是。哦，对了。导完数据后，记得别忘了到jdbc.properties里面去把数据库的连接信息换成你自己哦！
还有，如果有朋友没有用过Maven 或 不知道怎么配置Maven的，我以前整理过一篇关于Maven的配置和使用（），可以查看此篇博文并参考里面步骤配置Maven。
当然，如果你的Eclipse 默认的Maven 是可以正常使用的话，可以忽略上面的关于 Maven的配置的问题，直接将项目导入即可。
特别要说明的是，导入的项目要是Maven，导入后 最好 先 执行 一次 maven clean 。~
本次演示例子源码完整下载：（百度网盘）
假如百度云分享链接失效，请联系站长，我会补上的。
好了。到这里为止，关于 S2SM框架整合的一个CRUD的完整Web例子到此就结束了。如果你在阅读代码的时候有什么疑惑或者不懂，欢迎和我探讨哦！
后记：由于时间问题，这次的代码有些粗糙，可能有些代码写的不是很好。后续我会抽空优化一次的。同时谢谢大家的支持和谅解。
