不说了！日更啊！
今天终于把主页完成啦！给书加了图片，虽然图片严重不符，不够这都是小问题，现在还是测试阶段，到时候整理下数据库就行了。
同时终于加了登录页面，并把验证码移到了登录界面，注册页面就不需要了。
最后，加了个用户页面，不过目前只有退出账号功能233333

因为貌似jquery的post提交是在其他代码结束之后才运行的，于是我取巧把二维码的验证和表单提交分开写了，个人认为也算是个不错的思路吧~
$(function(){
var code;
$.post("../checkcode",function(data){
code=data;
});
$("#a1").click(function(){
$("#img").attr("src","/bookstore/imagecode?time="+new date().gettime());
});
var flag;
$("#code").keyup(function(){
$.post("/bookstore/checkcode",function(data){
code=data;
if(code==$("#code").val()){
flag=true;
}
else{
flag=false;
}
});
});
$("form").submit(function(){
if(flag){
return true;
}else{
alert("验证码错误");
return false;
}
});
});
个人感觉设计的还是挺精妙的，可以用一个函数就检测用户名是否存在，密码是否正确，同时也能在正确的时候返回user对象。
@override
public object login(string username, string password) throws sqlexception {
// todo auto-generated method stub
user user = dao.finduserbyname(username);
if(user==null) {
return "user";
}else {
if(user.getpassword().equals(password)) {
return user;
}else {
return "pass";
}
}
}
接收用户名密码，然后调用userservice的login方法，并对返回值做出相应处理。
