[解决办法]
<action name="loginAction" class="com.quxiuna.struts.action.login.LoginAction">

改下:

<action name="loginAction" class="loginAction">

我怀疑是spring的配置文件没有加载

工程结构图如下

[解决办法]
如果把Action给spring管理
web.xml里的Action的class=“spring里配置的Action的name”
[解决办法]
用注解方式注入就没这么多麻烦事了
[解决办法]
applicationContext.xml把这个spring的配置文件与web.xml同一目录下试试
[解决办法]
<constant name="struts.objectFactory" value="spring" />
这就话说明你把action交给spring管理了，
<action name="loginAction" class="com.quxiuna.struts.action.login.LoginAction">
这句话的意思是让struts去管理action，这样就矛盾了，
<bean id="loginAction" class="com.quxiuna.struts.action.login.LoginAction" scope="prototype">
这句话又是让spring管理action，又矛盾了
应该改成：
<action name="loginAction" class="LoginAction">
其他不变~~~

[解决办法]

CSS code

<bean id="loginAction" class="com.quxiuna.struts.action.login.LoginAction" scope="prototype">        <property name="userService">            <ref local="userService" />        </property>    </bean>上面的id 建议换成name="/loginAction" 和下面的struts中的action的path对应<struts>            <package name="login" extends="struts-default" namespace="/login">                <action name="loginAction" class="com.quxiuna.struts.action.login.LoginAction"> 这里的class不要。通过spring注入不需要class，已经和上面的bean对应了。                   <result name="success">/sendSuccss.jsp </result>            </action>        </package></struts>

[解决办法]
写一个junit先把DAO测通,再测service层,这个别人帮不了你,因为我们工具上没有你的项目环境.还得靠你自己.
