web起动@Autowired不能自动注入

web启动@Autowired不能自动注入
使用struts2,下面为action代码
Java代码

package com.edar.web.platform;     import org.apache.struts2.convention.annotation.InterceptorRef;   import org.apache.struts2.convention.annotation.InterceptorRefs;   import org.apache.struts2.convention.annotation.Namespace;   import org.apache.struts2.convention.annotation.Result;   import org.apache.struts2.convention.annotation.Results;   import org.springframework.beans.factory.annotation.Autowired;   import org.springframework.beans.factory.annotation.Qualifier;   import org.springframework.stereotype.Component;     import com.edar.components.AccountBean;   import com.edar.dao.util.Page;   import com.edar.model.Account;   import com.edar.service.platform.AccountService;   import com.edar.web.struts2.GenericAction;   @Component  @Namespace("/platform")   @InterceptorRefs( { @InterceptorRef("paramsPrepareParamsStack") })   @Results( { @Result(name = GenericAction.RELOAD, location = "account.action", type = "redirect") })   public class AccountAction extends GenericAction<AccountBean> {       private static final long serialVersionUID = 1900042912756344244L;       @Autowired      @Qualifier("accountServiceImpl")       private AccountService accountService;       private AccountBean accountBean;       private Page<AccountBean> page = new Page<AccountBean>(16,true);       public AccountBean getAccountBean() {           return accountBean;       }         public void setAccountBean(final AccountBean accountBean) {           this.accountBean = accountBean;       }         public Page<AccountBean> getPage() {           return page;       }         public void setPage(final Page<AccountBean> page) {           this.page = page;       }       @Override      public String delete(){           accountService.delete((Account) dozer.map(accountBean, Account.class));           return SUCCESS;       }         @Override      public String list(){           page = accountService.getPage(accountBean);           return SUCCESS;       }         @Override      protected void prepareModel(){           if(accountBean==null){               accountBean = new AccountBean();           }else{               if(accountBean.getAccountId()!=null){                   accountBean = (AccountBean)dozer.map(accountService.getAccount(accountBean.getAccountId()),                           AccountBean.class);               }           }                  }         @Override      public String save(){           Account account = (Account) dozer.map(accountBean, Account.class);           accountService.save(account);           accountBean.setAccountId(account.getAccountId());           return SUCCESS;       }         public AccountBean getModel() {           return accountBean;       }     }  

此action的junit测试代码

package com.edar.web.platform;     import org.junit.After;   import org.junit.AfterClass;   import org.junit.Assert;   import org.junit.Before;   import org.junit.BeforeClass;   import org.junit.Test;   import org.springframework.beans.factory.annotation.Autowired;     import com.edar.components.AccountBean;   import com.edar.test.SpringContextTestCase;     public class AccountActionTest extends SpringContextTestCase{                private static Long accountId;       @Autowired      private AccountAction accountAction;       @BeforeClass      public static void setUpBeforeClass() throws Exception {       }         @AfterClass      public static void tearDownAfterClass() throws Exception {       }         @Before      public void setUp() throws Exception {           AccountBean bean = new AccountBean();           bean.setName("ysheng53");           bean.setMobile("13819181747");           bean.setEmail("ysheng53@gmail.com");           bean.setPasswd("321");           accountAction.setAccountBean(bean);       }         @After      public void tearDown() throws Exception {       }       @Test      public void testSave() {           String result = accountAction.save();           accountId = accountAction.getAccountBean().getAccountId();           Assert.assertEquals(AccountAction.SUCCESS, result);       }       @Test      public void testList() {           String result = accountAction.list();           Assert.assertEquals(AccountAction.SUCCESS, result);           Assert.assertTrue(" 结果数小于0了 ",accountAction.getPage().getTotal()>0);       }         @Test(timeout=5000)       public void testDelete() {           accountAction.getAccountBean().setAccountId(accountId);           String result = accountAction.delete();           Assert.assertEquals(AccountAction.SUCCESS, result);           Assert.assertTrue("<=0",accountAction.getPage().getTotal()<=0);       }     }  

注意到action中的代码:
Java代码

@Autowired@Qualifier("accountServiceImpl")private AccountService accountService;

现象时，在junit测试代码执行时，accountService能够被注入，但是用tomcat6，在eclipse，wtp中启动时，accountService没有被注入,为null！

问题在查，谁遇到过类似问题;
问题补充
经过测试分析发现:
AccountAction在junit测试时用spring注入进去，而且只有唯一一个;
而在struts2中，每次请求都会有一个AccountAction的实例；

现在的问题是，struts2中新建实例时，那个private AccountService accountService;自动注入无效;


注：使用了Conventian Plugin
<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN" "http://struts.apache.org/dtds/struts-2.1.dtd"><struts><constant name="struts.convention.default.parent.package" value="crud-default" /><constant name="struts.convention.package.locators" value="web" /><!-- 用于CRUD Action的parent package --><package name="crud-default" extends="convention-default"><!-- 基于paramsPrepareParamsStack,增加store interceptor保证actionMessage在redirect后不会丢失 --><interceptors><interceptor-stack name="crudStack"><interceptor-ref name="store"><param name="operationMode">AUTOMATIC</param></interceptor-ref><interceptor-ref name="paramsPrepareParamsStack" /></interceptor-stack></interceptors><default-interceptor-ref name="crudStack" /></package><!-- 使用Convention插件,实现约定大于配置的零配置文件风格. 特殊的Result路径在Action类中使用@Result设定. --></struts>

struts.properties配置如下：

struts.devMode = truestruts.locale=zh_cnstruts.i18n.encoding=utf-8struts.objectFactory=spring 

如未解决，请你贴一下你的配置以及相关spring,struts2的包
