就是user==null，return "list";。进不去userDao.selcetall方法。我估计是在JSP里面出问题，但是看了半天不懂怎么解决，大神帮忙解决一下

ACTION
public String list(){
if(this.getPage()==null){
this.setPage(new Page());
}

List<Gjt_User>list=new ArrayList<Gjt_User>();

if (user!=null) {
System.out.println("...................进入到useraction");
Map<String, Object> param=new HashMap<String, Object>();
param.put("username", user.getUsername());
param.put("userphone", user.getUserphone());
list=userDao.selcetall(param);

this.page.setTotalRows(userDao.count(param));
param.put("page", this.page);
list=userDao.selcetall(param);

request.setAttribute("list", list);
}

return "list";

JSP
