struts2模型驱动方式action获取不到表单数据。

[blue灬]

过滤器中request可以获取表单数据

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

	/**
	 * 
	 */
	private static final long serialVersionUID = 1L;
	protected HttpServletRequest request;
	protected HttpServletResponse response;
	protected HttpSession session;
	protected ServletContext application;
	@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;
		String userName = request.getParameter("name");                   
		
		System.out.println("userName:"+userName);
		this.session=this.request.getSession();
	}
	
}

public class UsersAction extends SuperAction implements ModelDriven<Users> {
	private static final long serialVersionUID = 1L;
	private Users user =new Users();


	@Override
	public Users getModel() {
		
		return this.user;
	}

	// 用户登录动作
	public String login() {
		UsersDao userDao = new UsersDaoImpl();
		if(this.user!=null){
			if (userDao.userLogin(this.user)) {
				return "success";
			} else {
				return "failure";
			}
			
		}
		return "login_failure";
		
	}

}
