篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了SSH 框架整合（maven版本 xml配置方式）相关的知识，希望对你有一定的参考价值。
如何整合Struts2 Hibernate 和Spring 首先你必须了解三个框架是如何独立运行的：
代码下载：http://download.csdn.net/detail/zhanglinlang/9775160
Struts2 是通过在web.xml 中 Filter拦截器来启动自己的核心类StrutsPrepareAndExecuteFilter，完成事件的分发。
Spring 是通过 在web.xml 注册监听器来监听ContextLoaderListener，监听web应用的启动事件来完成自己的框架启动工作。
Hibernate 是通过创建SessionFactory工厂手动加载配置文件来完成启动工作，Hibernate是可以通过代码创建SessionFactory，就可以交给Spring通过ioc来控制该类的实例化。
下面就是整合代码：目录结构如下
首先在resource目录下创建 config目录方便管理：
首先配置
Hibernate ：
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
<session-factory name="foo">
<!-- 配置 打印sql语句到控制台 可选 -->
<property name="hibernate.show_sql">true</property>
<property name="hibernate.format_sql">true</property>
<!--
（重要配置）Hibernate自动建表 配置
create：先删除，再创建
update：如果表不存在就创建，不一样就更新，一样就什么都不做。
create-drop：初始化时创建表，SessionFactory执行close()时删除表。
validate：验证表结构是否一致，如果不一致，就抛异常。
-->
<property name="hbm2ddl.auto">update</property>
<!--
设置默认的事务隔离级别：
隔离级别 对应的整数表示
READ UNCOMMITED 1
READ COMMITED 2
REPEATABLE READ 4
SERIALIZEABLE 8
-->
<property name="connection.isolation">4</property>
<!-- 使用二级缓存，默认是未打开的。 -->
<!-- 指定要使用的缓存的提供商，这也就打开了二级缓存
<property name="cache.provider_class">org.hibernate.cache.HashtableCacheProvider</property>
<property name="cache.provider_class">org.hibernate.cache.EhCacheProvider</property>
-->
<!-- 开启使用查询缓存
<property name="cache.use_query_cache">true</property>
-->
<!-- 指定要使用二级缓存的实体类
<class-cache usage="read-write" class="cn.itcast.l_second_cache.Employee"/>
<class-cache usage="read-write" class="cn.itcast.l_second_cache.Department"/>
<collection-cache usage="read-write" collection="cn.itcast.l_second_cache.Department.employees"/>
-->
<!-- 导入映射文件 -->
<mapping resource="com/zll/entity/User.hbm.xml"/>
<mapping resource="com/zll/entity/Student.hbm.xml"/>
</session-factory>
</hibernate-configuration>
Struts.xml

整合细节知识点(了解)：
Struts2 和 Spring整合：就是将action的创建交由Spring管理。配置文件中class只需要配置Spring中bean的id就可以。
<action name="userAction" class="SpringBeanId" />
Hibernate和Spring整合：
1、创建连接池的对象交由spring管理
2、Spring提供了SessionFactory的封装类LocalSessionFactory，配置该类，并将数据源配置给它。
3、配置Spring的HibernateTemplate，将SessionFactory配置给他。替代session完成数据操作。
4、spring 事务管理配置，替代Hibernate事务管理
