web启动@Autowired不能自动注入

使用struts2,下面为action代码

Java代码

此action的junit测试代码

1. package com.edar.web.platform;

59.         Assert.assertTrue("<=0",accountAction.getPage().getTotal()<=0);     
60.     }     
61.

    String result = accountAction.delete();
    Assert.assertEquals(AccountAction.SUCCESS, result);

}

}

注意到action中的代码:


Java代码

1. @Autowired  
2. @Qualifier("accountServiceImpl")  
3. 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
