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.Namespace;

@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;
    }

}

package com.edar.web.platform;   
import org.apache.struts2.convention.annotation.InterceptorRef;

@Component

    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);
    }

}

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;

@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
