Answer 1

一、环境配置：
1.1 导包顺序：Struts ---->Spring ---> Hibernate
1.2 删除三个包：asm.jar/asm-attrs.jar /cglib-2.1.3.jar
1.3 添加一个包：commons-pool.jar
二、DAO：
2.1 代码：
DaoImpl extends HibernateDaoSupport
(CRUD: getHiberanteTemplate().save/update/delte/get/load/find(传参))
2.2 配置： 注入sessionFactory

三、Service:
3.1 代码：
3.1.1 所有业务方法中的实体类型应该是DTO 职责：处理业务/调用DAO
3.1.2 ServiceImpl 中定义DAO接口
3.2 配置： 注入DAO

四、Action:
4.1 代码：
4.1.1 Action 中定义Service接口
4.2 配置
4.2.1
<action type="org.springframework.web.struts.DelegatingActionProxy"/>
[将客户端请求转交给Spring容器的DelegatingActionProxy]
4.2.2
<plug-in
className="org.springframework.web.struts.ContextLoaderPlugIn">
<set-property property="contextConfigLocation"
value="classpath:beans.xml" />
4.2.3
<bean name="path" class="action路径">
<注入Service/>
</bean>

Answer 2

把你部署工程tomcat下项目西面的lib下asm-2.2.3.jar去掉

Answer 3

删除 WEB-INF/lib/asm-2.2.3.jar 然后重启 Tomcat.

Answer 4

Error creating bean with name 'sessionFactory' defined in ServletContext resource [/WEB-INF/applicationContext.xml]:这句话是关键，sessionFactory没有创建，仔细核对一下你的applicationContext.xml

Answer 5

你里面的包有重复的,具体哪个我忘记了，
