spring2.5+hibernate3.3+struts1.3整合开发：
hibernate核心安装包：hibernate3.jar,lib/required/*.jar,lib/optional/ehcache-1.2.3.jar
hibernate注解按照包下：lib/test/slf4j-log4j12.jar
spring安装包：dist/spring.jar,dist/modules/spring-webmvc-struts.jar,lib/jakarta-commons/commons-loggiong.jar,commons-dbcp.jar,commons-pool.jar,lib/aspectj/aspectjweaver.jar,aspectjrt.jar,lib/cglib/cglib-nodep-2.1_3.jar,lib/j2ee/common-annotations.jar,lib/log4j/log4j-1.2.15.jar
struts，解压包下所有的jar,建议把jstl-1.0.2.jar和standard-1.0.2.jar更换成1.1版本。spring中已经存在一个antlr-2.7.6.jar，所以把struts中的antlr-2.7.2.jar删除，避免冲突。
数据库驱动jar
hibernate二级缓存的配置：
<bean
id="sessionFactory"
class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="dataSource" ref="dataSource"/>
<property name="mappingResources">
<list>
<value>com/example/bean/Person.hbm.xml</value>
</list>
</property>
<property name="hibernateProperties">
<value>
hibernate.dialect=org.hibernate.dialect.MySQL5Dialect
hibernate.hbm2ddl.auto=update
hibernate.show_sql=false
hibernate.format_sql=false
hibernate.cache.use_second_level_cache=true
hibernate.cache.use_query_cache=false
hibernate.cache.provider_class=org.hibernate.cache.EhCacheProvider
</value>
</property>
</bean>
// 还要在类路径下放一个encache.xml文件；
<?xml version="1.0" encoding="UTF-8"?>
<encache>
<diskStore path="d:\cache"/>
<defaultCache maxElementsInMemory="1000"
enternal="false"
overflowToDisk="true"
timeToIdleSeconds="120"
timeToLiveSeconds="180"
diskPersistent="false"
diskExpiryThreadIntervalSeconds="60"/>
</encache>spring针对hibernate的事务管理器：
<bean id="txManager"
class="org.springframework.orm.hibernate3.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory"/>
</bean>
<tx:annotation-driven transaction-manager="txManager"/>spring可以自动管理session对象，所以不需要sessionFactory.openSession();只需要sessionFactory.getCurrentSession(),这是取得spring管理的那个session.
spring与struts集成
方案一： 在 web容器中实例化spring容器。
指定spring的配置文件，默认从web根目录寻找配置文件，我们可以通过spring提供的classpath:前缀指定从类路径下寻找
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:beans.xml</param-value>
</context-param>
<!--对spring容器进行实例化-->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>在web容器中配置struts：
<servlet>
<servlet-name>struts</servlet-name>
<servlet-class>org.apache.struts.action.ActionServlet</servlet-class>
<init-param>
<param-name>config</param-name>
<param-value>/WEB-INF/struts-config.xml</param-value>
</init-param>
<load-on-startup>0</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>struts</servlet-name>
<url-pattern>*.do</url-parrern>
</servlet-mapping>如果action没有交给spring管理时，我们可以通过下面的语句获取spring容器实例：
WebApplicationcontext ctx = WebApplicationContextUtils.getWebApplicationContext(this.getService().getServiceContext());把action交给spring管理后，我们可以使用依赖注入在action中注入业务层的bean。
注意两点：
一是确保action的path属性值与bean的名称相同。
<action path="/person/list" ...></action>
//spring配置：
<bean name="/person/list" class="cn.itcast.web.action.PersonAction"/> 二是在struts-config.xml中配置一个控制器
<controller>
<set-property property="processorClass"
value="org.springframework.web.struts.DelegatingRequestProcessor"/>
</controller>spring解决struts1.3乱码问题：
在web容器里：
<filter>
<filter-name>encoding</filter-name>
<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
<init-param>
<param-name>encoding</param-name>
<param-value>UTF-8</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>encoding</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>spring解决hibernate因session关闭导致的延迟加载异常问题。

<filter-mapping>
<filter-name>OpenSessionInViewFilter</filter-name>
