求大虾指点,spring注入时成功,调用时为空

vacan99 2011-02-14 08:12:30

使用的是struts2.1.8 + spring 2.5 + hibernate 3.3
出问题的是UpdateAction,启动tomcat调试时,注入是成功的,activityBiz不为空,
但是页面调用时就成空了
下面是部分源代码,其他类中没有这个问题,全部注入成功,调用时也不为空
如果把这个类改个类名的话就没问题了,但是跟其他包中的action就不统一了
请大虾们看看

这是action类
public class UpdateAction extends ActionSupport{

/**
*
*/
private static final long serialVersionUID = -2462386063736802658L;

private IActivityBiz activityBiz;//业务逻辑类

public IActivityBiz getActivityBiz() {
return activityBiz;
}

public void setActivityBiz(IActivityBiz activityBiz) {
this.activityBiz = activityBiz;
}
@Override
public String execute() throws Exception {

if(this.activityBiz == null) {
System.out.println("null");
}
return null;
}

这是applicationContext.xml
