  你的 SuperAction 类是否没有初始化 session 啊，看下面，在 setServletRequest() 有给session 辅助哦：

  package action;

  
  

  import javax.servlet.ServletContext;

  import javax.servlet.http.HttpServletRequest;

  import javax.servlet.http.HttpServletResponse;

  import javax.servlet.http.HttpSession;

  
  

  import org.apache.struts2.interceptor.ServletRequestAware;

  import org.apache.struts2.interceptor.ServletResponseAware;

  import org.apache.struts2.util.ServletContextAware;

  
  

  import com.opensymphony.xwork2.ActionSupport;

  
  

  //所有Action动作的父类

  public class SuperAction extends ActionSupport implements ServletRequestAware,ServletResponseAware,ServletContextAware {

  
  

  /**

  * 

  */

  private static final long serialVersionUID = 7727505312022359301L;

  protected HttpServletRequest request;  //请求对象

  protected HttpServletResponse response;  //响应对象

  protected HttpSession session;  //会话对象

  protected ServletContext application;  // 全局对象

  @Override

  public void setServletContext(ServletContext application) {

  this.application = application;

  }

  
  

  @Override

  public void setServletResponse(HttpServletResponse response) {

  this.response = response;

  }

  
  

  @Override

  public void setServletRequest(HttpServletRequest request) {

  this.request = request;

  this.session = this.request.getSession();

  }

  
  

  }
