package person.action;

import javax.servlet.ServletContext;
import org.apache.struts.action.Action;
import org.apache.struts.action.ActionServlet;
import org.springframework.web.context.WebApplicationContext;
import org.springframework.web.context.support.WebApplicationContextUtils;

import person.PersonService;
public class BaseAction extends Action {


private PersonService personService;

public void setServlet(ActionServlet actionServlet) {

super.setServlet(actionServlet);
ServletContext servletContext = actionServlet.getServletContext();
WebApplicationContext wac = null;
wac=WebApplicationContextUtils.getRequiredWebApplicationContext(servletContext);
this.personService = (PersonService) wac.getBean("personServiceImp");
}
protected PersonService getPersonService() {
return this.personService;
}

}
當我調試時，在wac=WebApplicationContextUtils.getRequiredWebApplicationContext(servletContext); 處出現異常，我想知道為什么會這樣，應該怎樣解決，請高手指教，謝謝！??回復

你用的是hibernate3.0吧! 但你的spring配置文件中不是
<bean id="sessionFactory" class="org.springframework.orm.hibernate.LocalSessionFactoryBean">

應該是:
<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
你試試!??回復

在spring配置文件中配置一下action 如:
<bean name="/loginAction" class="com.derek.action.LoginAction" singleton="false">
<property name="login">
<ref bean="loginBOProxy" />
</property>
</bean>

和在struts-config配置文件中聲明loginAction的
type = "org.springframework.web.struts.DelegatingActionProxy "

那么在action中有set,get方法, spring 會幫你注入你定義的bean,無須你再自己用WebApplicationContextUtils去獲得bean實例
