Question

请在下面找到我的代码

的web.xml

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>/WEB-INF/applicationContext.xml</param-value>
</context-param>

<listener>
    <listener-class>
        org.springframework.web.context.ContextLoaderListener               
    </listener-class>
</listener>

我的applicationContext.xml就在这里

我的行动课就在这里

 package com.qantas.cardselector.action.cardslist;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.apache.struts.action.Action;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;

import com.qantas.cardselector.form.CardsListForm;
import com.qantas.cardselector.service.CardManagementService;
import com.qantas.cardselector.vo.SearchFilterVO;

public class CardsListAction extends Action {

    public CardManagementService cardManagementService;

    @Override
    public ActionForward execute(ActionMapping mapping, ActionForm form,
            HttpServletRequest request, HttpServletResponse response)
            throws Exception {
        try {   
            System.out.println("action started");
            SearchFilterVO searchFilterVO =null;
            if(getCardManagementService()!=null)
            {
                String returnvalue = getCardManagementService().retrieveParams(searchFilterVO);
                System.out.println("returnvalue"+returnvalue);
            }


        } catch (Exception e) {
            System.out.println("Error:" + e.getMessage());
            e.printStackTrace();
        }

        return mapping.findForward("success");
    }

    public CardManagementService getCardManagementService() {
        return cardManagementService;
    }

    public void setCardManagementService(CardManagementService cardManagementService) {
        this.cardManagementService = cardManagementService;
    }

}

这个动作类总是在调用代码中显示的服务对象时抛出空指针异常...请任何人帮忙......

Answer 1

伙计我已在下面的问题中找到答案，

刚刚在struts-config.xml

中添加了一段代码

<controller processorClass="org.springframework.web.struts.DelegatingRequestProcessor"/> 

<plug-in className="org.springframework.web.struts.ContextLoaderPlugIn">
    <set-property property="csntextConfigLocation" value="/WEB-INF/applicationContext.xml"/>
</plug-in>

并添加了一个空的action-servlet.xml文件

Bean没有在Spring中初始化
