Struts2+Sring+Hibernate簡單配置
Struts2+Spring+Hibernate是J2EE的最新流行框架。本篇是我搭建這個框架的經驗總結，有不少人搭建這個框架總會遇到 css
大大小小的問題，網上也沒有什麼行之有效的方案或成體系的介紹，因此我就決定總結一下個人搭建過程。給一些搭 html
建尚存問題的朋友提供幫助。 java
我用這個框架，實現的是基本的CRUD功能的一個僱員管理系統，原本打算豐富一下功能，可是一直沒能抽出空去搞。 mysql
目前版本暫定爲1.0，除了CRUD外還配置了表單驗證框架JSValidation。功能都能很順利的實現。 web
如今分享部分源碼，來講明一些注意事項。 spring
如下是部分搭建過程及源碼： sql
1.先組合實現Hibernate3.2+Spring2.5支持，刪除hibernate.cfg.xml文件，修改applicationContext.xml文件的內容，增長SessionFactory和dataSource的設置。 express
2.經過MyEclipse的嚮導方式，生成POJO類和對應的映射文件。 apache
3.修改applicationContext.xml文件中<property name="mappingResources">元素的內容。 session
4.編寫DAO接口和實現類。
5.修改applicationContext.xml文件，增長對Dao實現類的配置。
6.組合Struts2和Spring2.5，修改web.xml文件，增長struts2的所須要的過濾器配置。
7.增長struts2相應類庫，增長struts2與spring的配置jar包。
8.拷貝struts.xml文件到src根目錄下，再修改struts.xml文件，進行常量配置。
9.修改web.xml文件，配置Spring監聽器，和上下文變量。並增長OpenSessionInViewFilter的設置。
10.寫入action類。
11.配置struts.xml文件。
12.修改applicationContext.xml
13.編寫Jsp文件。
14.加載運行項目。
下面是關鍵文件的源碼：
