选择jar的步骤:
1.Struts 2：选择Struts Core(核心库)和Struts 2 Spring(包含集成Spring插件)的两个最基本库，其他根据需要可以添加。
2.选择Spring3.0版本，类库选择 Spring 3.0 AOP、Spring 3.0 Core、Spring 3.0 Persistence Core、Spring 3.0 Persistence JDBC、Spring 3.0 Web 5个库，并勾选复制到本地WEB-INF/lib目录。
3.选择Hibernate3.3版本，如果要使用注解可选中启用annotation，但是会对后续自动生成实体类造成麻烦，不选就是用xml文件形式进行实体类映射，默认勾选Hibernate 3.3 Annotation & Entity Manager、Hibernate 3.3 Core Libraries两个类库，复制jar文件到本地WEB-INF/lib文件夹下。

2. web.xml
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 |
<context-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/classes/applicationContext.xml</param-value> </context-param> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <filter> <filter-name>struts2</filter-name> <filter-class> org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class> </filter> <filter-mapping> <filter-name>struts2</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> |
3. struts.xml 配置的Action的时候,class属性只给出beanId的名字就可以了。
4. applicationContext.xml,配置

5. 获得HibernateTemplate的方法
I:
|
1 |
private HibernateTemplate hibernateTemplate; |
II:
|
1 2 3 4 |
@Resource(name="hibernateTemplate") public void setHibernateTemplate(HibernateTemplate hibernateTemplate) { this.hibernateTemplate = hibernateTemplate; } |
6. 在Struts2获得WebApplicationContext的方法
I: Action实现implements ServletRequestAware,并实现setServletRequest()方法。
II:
|
1 2 3 4 5 |
public void setServletRequest(HttpServletRequest request) { // TODO Auto-generated method stub this.request = request; } |
III:以下是获得的方法
|
1 2 3 4 |
WebApplicationContext ctx = WebApplicationContextUtils.getWebApplicationContext(request.getSession().getServletContext()); ApplicationContext ac1 = WebApplicationContextUtils.getRequiredWebApplicationContext(request.getSession().getServletContext());//失败时抛出异常 ApplicationContext ac2 = WebApplicationContextUtils.getWebApplicationContext(request.getSession().getServletContext()); //失败时返回null WebApplicationContext webApplicationContext = (WebApplicationContext)request.getSession().getServletContext().getAttribute(WebApplicationContext.ROOT_WEB_APPLICATION_CONTEXT_ATTRIBUTE); |
Spring3跟hibernate整合的配置总结:其实配置一个Dao需要4个Bean。数据源Bean被装配到会话工厂Bean；会话工厂Bean被装配到HibernateTemplate；最后HibernateTemplate被装配到Dao的Bean。为了让事情变得简单一些，Spring停工了HibernateDaoSupport，它能够让我们把会话工厂Bean直接装配到Dao类，它会自动创建一个HibernateTemplate供Dao使用。只需要Dao集成HibernateDaoSupport类就可以了，在使用HibernateTemplate时调用getHibernateTemplate() 方法即可.
