web启动@Autowired不能自动注入

使用struts2,下面为action代码

此action的junit测试代码

}

注意到action中的代码:

Java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
