出现的错误是:Unable to instantiate Action defined for 'userlist' in namespace '/user'UserAction
在网上搜了好多,可是基本都没什么作用。。
这是struts的配置代码:
<constant name="struts.objectFactory" value="spring" />
<package name="user" namespace="/user" extends="struts-default">
<action name="userlist" class="userAction">
<result name="list">/WEB-INF/user/userList.jsp</result>
</action>
</package>
这是web.xml的配置文件:
<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>
<filter>
<filter-name>struts2</filter-name>
<filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class>
</filter>
<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
这个是我action的定义:
@Controller
public class UserAction {
public String userList()
{
return "list";
}
public String execute()
{
return "list";
}
}
就报上述错误了。
本人刚刚学习这方面的知识,望高手指教!鄙人万分感谢!
你的spring 配置文件呢?
目测是你的action 木有实例化/ class="userAction" 在哪里?
这是我的beans.xml文件 ,

@shenghaishiweini: 在你的spring 配置里面加一个bean 也就是 action的bean
<bean id="userAction" class="这里是完整的包名" scope="prototype"/>
@Beyond-bit: 谢谢你!再你的帮助下,我已经搞定了!非常感谢!
