Answer 1

web.xml 里面配置不对使用ContextLoaderListener来加载web.xml的时候。
需要加入spring的applicationContext.xml等内容例如：
==================================================
使用ContextLoaderListener加载web.xml
--------------------------------------------------
<'context-param>
<'param-name>contextConfigLocation<'/param-name>
<'param-value>
/WEB-INF/daoContext.xml
/WEB-INF/applicationContext.xml
<'/param-value>
<'/context-param><'listener>
<'listener-class>
org.springframework.web.context.ContextLoaderListener
<'/listener-class>
<'/listener>
==================================================还有一种方法使用的ContextLoaderServlet
==================================================
使用ContextLoaderServlet加载web.xml
--------------------------------------------------
<'context-param>
<'param-name>contextConfigLocation<'/param-name>
<'param-value>
/WEB-INF/daoContext.xml
/WEB-INF/applicationContext.xml
<'/param-value>
<'/context-param><'servlet>
<'servlet-name>context<'/servlet-name>
<'servlet-class>
org.springframework.web.context.ContextLoaderServlet
<'/servlet-class>
<'load-on-startup>1<'/load-on-startup>
<'/servlet>
==================================================最后，还有一种方法DispatcherServlet
==================================================
使用DispatcherServlet加载web.xml
--------------------------------------------------
<'web-app>
...
<'servlet>
<'servlet-name>example<'/servlet-name>
<'servlet-class>
org.springframework.web.servlet.DispatcherServlet
<'/servlet-class>
<'load-on-startup>1<'/load-on-startup>
<'/servlet>
<'servlet-mapping>
<'servlet-name>example<'/servlet-name>
<'url-pattern>*.form<'/url-pattern>
<'/servlet-mapping>
...
<'/web-app>
==================================================

Answer 2

另外，applicationcontext.xml加载之后，org.springframework.beans.factory.NoSuchBeanDefinitionException:   No   bean   named   'transactionManager'   is   defined 
请确认，你定义了'transactionManager'这个bean地描述注意，是bean地描述定义

Answer 3

项目启动时加载XML文件出错，在代码中有注入这个类transactionManager，但是在xml文件中没有这个Bean的ID，检查XML文件和代码中引用的名称是否一致，建议在命名时参照规范，例如:类名：ActionSupper   对象名：actionSupper    如果有良好的代码规范，相信以后不会出现这样的问题。

Answer 4

transactionManager没有被定义，查查bean定义的配置文件看看，
