ss2h框架action基类BaseAction注入service失败

登录报空指针异常，打断点发现userAction走到BaseAction所有属性都为空
代码：BaseAction
import java.io.IOException;
import java.io.PrintWriter;
import java.io.Serializable;
import java.util.List;

import javax.annotation.Resource;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;

import org.apache.struts2.ServletActionContext;

import com.opensymphony.xwork2.ActionSupport;

import cn.pojo.*;
import cn.service.*;

public class BaseAction extends ActionSupport implements Serializable {
@Resource
public AsRoleService asRoleService;
@Resource
public AsFunctionService asFunctionService;

private List<RoleFunction> roleFunctions;

public List<RoleFunction> getRoleFunctions() {
    return roleFunctions;
}

public void setRoleFunctions(List<RoleFunction> roleFunctions) {
    this.roleFunctions = roleFunctions;
}

public BaseAction() {
    AsUser user2 = (AsUser) this.getSession().getAttribute("user");
    if (user2 != null) {
        List<Integer> list = asRoleService.conFindFcId(user2.getRoleId());
        this.roleFunctions = this.asFunctionService.conFindFcById(list);
    }
}

代码：AsUserAction
import java.io.IOException;
import java.io.PrintWriter;
import java.util.List;

import javax.annotation.Resource;

import net.sf.json.JSON;
import net.sf.json.JSONArray;

import cn.pojo.*;
import cn.service.*;

public class AsUserAction extends BaseAction {
@Resource
private AsUserService asUserService;
// @Resource
// private AsRoleService asRoleService;
// @Resource
// private AsFunctionService asFunctionService;
@Resource
private AsAccountService asAccountService;

private List<RoleFunction> roleFunctions;
private AsUser user;
private AsAccount account;
private List<AsAccountdetail> listADet;
private Integer accCount;
private List<AsUser> listU;
public String login() {// 登录
    AsUser user2 = this.asUserService.conFindByUserCode(this.user);
    // List<Integer> list = asRoleService.conFindFcId(user2.getRoleId());
    // this.roleFunctions = this.asFunctionService.conFindFcById(list);
    // super.getSession().setAttribute("roleFunctions", roleFunctions);
    asUserService.conUpdateIsStart(user, user2.getId());
    user2.setIsStart(user.getIsStart());
    super.getSession().setAttribute("user", user2);
    super.getSession().setAttribute("id", user2.getId());
    asUserService.conUpdateLastLoginTime(user2.getId());
    return "success";
}

这个是火狐报的最下面的错，如果需要全部报错我可以贴出来
希望大神解答
是不是需要BaseAction实例化？
