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:

Eclipse_file

演示工程的目录结构

index

项目的首页

showList

查询出的数据列表

add

新增数据的界面

edit

编辑数据的界面

pageUp

分页中的上一页

pageDown

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(http://www.baikeyang.com/code/985.html),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:http://pan.baidu.com/s/1o6n9yyA(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。
