这是applicationContextv.xml
- XML code

在loginAction里调用personDao，总是空指针，求解，捣鼓一天了
------解决方案--------------------
personDao在spring那里注入了没
------解决方案--------------------
额，不会啊，dao、action都有注入了啊，你的personDao在action中有set\get()方法吗，别忘记它了
------解决方案--------------------
personDao在action里面是要有相关的get和set方法的。还有，那个personDao是要和Spring的配置文件里面一样的。
------解决方案--------------------
就是这个applicationContext.xml。。

对了，，你这个是struts1，要在struts-config.xml里面配置一个control或者是plug-in
plug-in是这么配的，不过要加一个plug-in的插件包的，包名叫“spring-webmvc-struts.jar”
- XML code
<plug-in className="org.springframework.web.struts.ContextLoaderPlugIn"> <set-property property="contextConfigLocation" value="/WEB-INF/applicationContext.xml" /> </plug-in>
