web启动@Autowired不能自动注入

使用struts2,下面为action代码
Java代码

public AccountBean getModel() {

}

package com.edar.web.platform;

此action的junit测试代码

Java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()&gt;0);   
}   

@Test(timeout=5000)   
public void testDelete() {   
    accountAction.getAccountBean().setAccountId(accountId);   
    String result = accountAction.delete();   
    Assert.assertEquals(AccountAction.SUCCESS, result);   
    Assert.assertTrue("&lt;=0",accountAction.getPage().getTotal()&lt;=0);   
}   

}

注意到action中的代码:

Java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
