ajax的POST请求到springmvc

Question

ajaxPOST请求代码：
function loginBtn(){
    debugger;
    $.ajax({
           type: "POST",
           url: "/doLogin",
           //把form表单做了一个序列化
           data: $("#loginForm").serialize(),
           success: function(msg){
               debugger;
               if("success"== msg.result){

// window.location.href="/mainPage";
// location="/mainPage";
location.href="/mainPage";
}else{
alert("错误！！");
}
},
error: function(msg){
debugger;
alert(msg);
}
});
}

Controller代码

@Controller

public class LoginController {
@RequestMapping(value = "/login", method = RequestMethod.GET)
public String login() {
return "login";
}

@RequestMapping(value = "/doLogin", method = RequestMethod.POST)
public @ResponseBody Map<String, String> doLogin(Login login) {
    System.out.println(login.getUsername() + "" + login.getPassword());
    Map<String, String> map = new HashMap<String, String>();
    map.put("result", "success");
    return map;
}

请问这个怎么处理？，还有就是我在浏览器点击后退时，怎么刷新页面（不带参数）

解决办法是在返回的ajax里面写个window.location.herf，在Controller里面返回map，用json进行传递
