steps2>AbstractBaseAction

   我们在编写action中有很多时候，都会在每个action中继承ActionSupport和实现SessionAware, ServletRequestAware, ServletResponseAware，其实想想还是可以优化的，现在姑且叫做AbstractBaseAction吧

import com.opensymphony.xwork2.ActionSupport;
import java.util.Map;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.log4j.Logger;
import org.apache.struts2.interceptor.ServletRequestAware;
import org.apache.struts2.interceptor.ServletResponseAware;
import org.apache.struts2.interceptor.SessionAware;

public abstract class AbstractBaseAction extends ActionSupport implements
        SessionAware, ServletRequestAware, ServletResponseAware {
    public static final Logger log = Logger.getLogger(AbstractBaseAction.class);//取得log对象，方便在action基类中调用
