System.out.println(user.toString());
rss.setStatus("0");
rss.setMsg("登陆成功");
return rss;
}else{
rss.setStatus("1");
rss.setMsg("登陆失败，请检查账号密码");
return rss;
}
} catch (Exception e) {
e.printStackTrace();
rss.setStatus("2");
rss.setMsg("登陆失败");
return rss;
}
}
@RequestMapping("/register.action")
public String Register(User user){
System.out.println("Register loading...");
User rs = userServ.register(user.getUname(), user.getPwd());
if(rs.getUname() != "" && rs.getPwd() != ""){
System.out.println(rs.toString());
return "login.jsp";
}else{
return "/WEB-INF/login/fail.jsp";
}
}
}
如图，程序可以执行到controller中if那边那个system.out.print输出了账号密码，但我在ajax的success和error都放了alert，全都没触发，看了浏览器后台也完全没错误。
求帮忙看看，感谢
