Struts2.1+Hibernate3.1+Spring2.0组合

对于S2SH的组合，其实注意几点就可以了：

第一： 由于Struts2的Action是有状态，而Spring中的Bean默认为单例模式的，故一定要将Spring中配置Struts2的Action的scope设置为prototype 。而Struts1中的Action是无状态故在SSH时可以不用将Spring设置为prototype！

第二：Struts2与Spring的组合不像Struts1，它需要一个Struts2中一个struts2-spring-plugin-2.1.6.jar也不需要在struts.xml中加入其它的配置，只需将struts.xml中的action的class的值改成action在Spring中配置的Bean的id 就可以了！

简单的例子如下：

（说明这个例子当中包括Struts2大部分的内容，主要是想体验一下Struts2的功能）

数据库如下：uid,ufristName,ulastName,uage四个字段

一，加入Spring的支持

二，加入Hibernate的支持(Hibernate的配置由Spring去管理)

三，加入Struts2的支持

四，加入Struts2对Spring的插件(struts2-spring-plugin-2.1.6.jar)

 

在web.xml中加入对Spring和Struts2的配置：

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

	</context-param>

	<listener>

			org.springframework.web.context.ContextLoaderListener

	</listener>

	<filter>

	</filter>
	<filter-mapping>
		<filter-name>struts2</filter-name>
		<url-pattern>/*</url-pattern>
	</filter-mapping>

	<welcome-file-list>
		<welcome-file>index.jsp</welcome-file>
	</welcome-file-list>
</web-app>

 UsersDAO的接口如下：

public interface UsersDaoInter {

	public abstract void save(Users transientInstance);

	public abstract void delete(Users persistentInstance);

	public abstract void delete(final int uId);

	public abstract Users findById(java.lang.Integer id);

	public abstract List findByExample(Users instance);

	public abstract List findByProperty(String propertyName, Object value);

	public abstract List findAll();

	public abstract Users merge(Users detachedInstance);

}

 UsersService接口如下：

public interface UsersServiceInter {

	public abstract void save(Users transientInstance);

	public abstract void delete(Users persistentInstance);

	public abstract void delete(final int uId);

	public abstract Users findById(java.lang.Integer id);

	public abstract List findByExample(Users instance);

	public abstract List findByProperty(String propertyName, Object value);

	public abstract List findAll();

	public abstract Users merge(Users detachedInstance);
	/**
	 * 导出用户列表的Excel
	 * @return
	 */
	public abstract InputStream exportUsers();

}

 Spring的applicationContext.xml配置如下：

<?xml version="1.0" encoding="UTF-8"?>

由于文件很多，不能全部显示，下面的压缩包是本程序的源码，由于jar很大上传不了，故不包含S2SH的jar包
