用ssm和ajax做了用户登录注册功能，结果发现登录成功之后页面返回了一个字符串
controller层
@RequestMapping("dologin")
@ResponseBody
public boolean dologin(@RequestParam("username") String username,
@RequestParam("password")String password, User user, Model model, HttpSession session
, HttpServletRequest request, HttpServletResponse response){
user = userService.login(user.getUsername(), user.getPassword());
Boolean flag ;
response.setContentType("text/html;charset=UTF-8");
response.setCharacterEncoding("UTF-8");
// user.setUsername(username);
// user.setPassword(password);
System.out.println("dologin");
if(userService.login(username,password) != null)
{
model.addAttribute("username", username);
session.setAttribute("user",user);
flag = true;
// model.setViewName("Dashboard/index");
} else {
System.out.println("账号或密码错误");
flag = false;
// mv.setViewName("tutorial/tologin");
}
return flag;
// System.out.println(model);
// return mv;
}
登录按钮
<form class="login-form" action="${pageContext.request.contextPath}/dologin" method="post">
<input type="text" name="username" placeholder="username"/>
<input type="password" name="password" placeholder="password"/>
<button type="submit" value="login" id="loginBtn" >Login</button>
<p class="message">无账号？ <a href="#">创建账号</a></p>
</form>
ajax
$(function() {
$("#loginBtn").click(function() {
var username = $("#username").val();
var password = $("#password").val();
$.ajax({
type:"POST",
url:"dologin",
data:{"username" : username,
"password" : password},
dataType:"json",
success:function(flag){
console.log("进入ajax")
if(flag){
window.location.href="Dashboard/index.jsp";
}else{
alert("登录失败");;
}
}
});
});
});
不是很懂，求大神支招。
想用异步更新实现登陆注册功能。
