首先就着手解決包的問題
從網上東拼西湊的文章中，然後一個一個包的測試，首先我先在Tomcat下測試的。所以其中多了幾個tomcat需要的commons包。
首先貼一下Web.xml文件的內容吧。
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee

<!-- log4j配置文件 -->

</context-param>
<!-- 加載Spring配置文件 -->

<!--解決Hibernate延遲加載出現的問題，需要放到struts2過濾器之前-->

</filter-mapping>
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
</web-app>
然後再貼一下applicationContext.xml文件的內容。畢竟是spring配置，最核心的東西，把所有其他框架整合到一起的樞紐。

</aop:config>
</beans>
在裏面也包含了另一個使用Tomcat的DataSource，已經註釋起來了。我後面使用的Jboss，所以就先註釋起來了。
最後一個配置文件就是struts.xml的內容了
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
"http://struts.apache.org/dtds/struts-2.0.dtd">
<struts>
<constant name="struts.action.extension" value="shtml" />
<constant name="struts.objectFactory" value="spring" />
<include file="struts-default.xml" />
<package name="default" extends="struts-default">
<interceptors>
<interceptor-stack name="defaultStack"></interceptor-stack>
</interceptors>
<global-results>
<result name="error">/error.jsp</result>
</global-results>
</package>
<include file="struts-login.xml" />
</struts>
爲了業務區分，我把struts文件放不同文件中
struts-login.xml 的內容
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
"http://struts.apache.org/dtds/struts-2.0.dtd">
<struts>
<package name="user" extends="default">
<!--登錄界面 -->
<action name="login" class="com.gts.cns.login.action.UserLoginAction"
method="login">
<result name="success">

</result>
</action>
<action name="loginError" class="com.gts.cns.login.action.UserLoginAction"
method="error">
<result name="success">
/jsp/error.jsp
</result>
</action>
</package>
</struts>
最後需要貼一下jboss數據庫連接的文件mysql-ds.xml。原始的文件在/jboss-4.2.2.GA/docs/examples/jca目錄下，然後就看你鏈接什麼數據庫了，我使用的是mysql，所以複製了mysql-ds.xml，把它複製到/jboss-4.2.2.GA/server/default/deploy目錄下面，因爲我的工程是部署在這個下面的。
<!-- $Id: mysql-ds.xml 63175 2007-05-21 16:26:06Z rrajesh $ -->

接着我這裏貼一下我的測試代碼

數據庫部分我就貼一下圖片吧
這個是數據庫內容了
現在我把jboss啓動起來，因爲我使用MyEclipse的插件，所以JBoss的配置文件不需要更改
直接啓動起來後發現問題了。

其中主要看這條錯誤，告知是sessionFactory或者hibernateTemplate是空的，其實原本我也不知道是怎麼一回事，直接就google了，發現已經有人跟到hibernate源碼裏面去了，並且提示sessionFactory爲空的。我也就參照那位仁兄的建議，手動塞進去了。
代碼如下：
public void setSuperSessionFactory(SessionFactory sessionFactory){
super.setSessionFactory(sessionFactory);
}
這塊代碼我就寫在了BaseDaoImpl.java中，因爲我每一層之上都加了一個base層，我是考慮爲今後加統一功能的時候方便，現在就正好派上用場了。然後我再次啓動服務器。
問題又來了

這個問題就比較折騰了，我當時也無從着手的感覺，網上搜索的也亂七八糟的，有點似是而非的感覺。偶然看到一帖中說到，jboss的hibernate老了，只要刪除就可以了。爲了以防萬一，我將jboss中的hibernate-*.jar全部貼到文件夾外面。然後重啓就正常了。
接着我再訪問這個項目的時候，console打印的消息就是：
14:14:51,203 INFO [STDOUT] ==============進入Service==================
14:14:51,203 INFO [STDOUT] =================進入DAO==================
14:14:51,515 INFO [STDOUT] Hibernate: select tbuser0_.id as id0_, tbuser0_.text as text0_, tbuser0_.user as user0_ from tb_user tbuser0_
14:14:51,562 INFO [STDOUT] 我來測試一下
後面我一個包一個包的測試，證實了之前帖子中說的，hibernate-annotations.jar這個包的問題。只要將這個包刪除就可以了。jboss4.2.2服務器就完全正常了。因爲後續功能還沒加上去，所以是否還缺少包我就不得而知了，只能一步一步來。希望我遇到的問題的解決方案，能夠幫到各位吧。如果有錯誤，也請提出來。謝謝。
