如何使用Spring MVC将Facebook返回的响应数据保存在Java类中

我正在尝试保存Facebook响应返回的用户数据。我使用的是FacebookJavascript。响应是JSon格式的，我想先解析它，然后用java将它保存到我的数据库中。

<script>
  // This is called with the results from from FB.getLoginStatus().
  function statusChangeCallback(response) {
    console.log('statusChangeCallback');
    console.log(response);
    // The response object is returned with a status field that lets the
    // app know the current login status of the person.
    // Full docs on the response object can be found in the documentation
    // for FB.getLoginStatus().
    if (response.status === 'connected') {
      // Logged into your app and Facebook.
    /*   var uid = response.authResponse.userID;
      var accessToken = response.authResponse.accessToken;
      console.log("User id is" + uid);
      console.log(accessToken); */
      document.getElementById('accesstoken').value=response.authResponse.accessToken;
      console.log(response.authResponse.accessToken);
      testAPI();
    } else if (response.status === 'not_authorized') {
      // The person is logged into Facebook, but not your app.
      document.getElementById('status').innerHTML = 'Please log ' +
        'into this app.';
    } else {
      // The person is not logged into Facebook, so we're not sure if
      // they are logged into this app or not.
      document.getElementById('status').innerHTML = 'Please log ' +
        'into Facebook.';
    }
  }
  // This function is called when someone finishes with the Login
  // Button.  See the onlogin handler attached to it in the sample
  // code below.
  function checkLoginState() {
    FB.getLoginStatus(function(response) {
      statusChangeCallback(response);
    });
  }
  window.fbAsyncInit = function() {
  FB.init({
    appId      : 'xxxxxxxxxxxxxxxxxxxx',
    cookie     : true,  // enable cookies to allow the server to access 
                        // the session
    xfbml      : true,  // parse social plugins on this page
    version    : 'v2.2' // use version 2.2
  });
  // Now that we've initialized the JavaScript SDK, we call 
  // FB.getLoginStatus().  This function gets the state of the
  // person visiting this page and can return one of three states to
  // the callback you provide.  They can be:
  //
  // 1. Logged into your app ('connected')
  // 2. Logged into Facebook, but not your app ('not_authorized')
  // 3. Not logged into Facebook and can't tell if they are logged into
  //    your app or not.
  //
  // These three cases are handled in the callback function.
  FB.getLoginStatus(function(response) {
    statusChangeCallback(response);
  });
  };
  // Load the SDK asynchronously
  (function(d, s, id) {
    var js, fjs = d.getElementsByTagName(s)[0];
    if (d.getElementById(id)) return;
    js = d.createElement(s); js.id = id;
    js.src = "//connect.facebook.net/en_US/sdk.js";
    fjs.parentNode.insertBefore(js, fjs);
  }(document, 'script', 'facebook-jssdk'));
  // Here we run a very simple test of the Graph API after login is
  // successful.  See statusChangeCallback() for when this call is made.
  function testAPI() {
     // window.location="http://localhost:8080/SpringMvcHibernateJavaBased/list";
    console.log('Welcome!  Fetching your information.... ');
    FB.api('/me',  function(response) {
      console.log('Successful login for: ' + response.name);
      console.log(response);
      document.getElementById('status').innerHTML =
        'Thanks for logging in, ' + response.name + '!';
      document.getElementById('usernamefb').value=response.name;
      document.getElementById('userId').value=response.id;
      document.getElementById('emailfb').value=response.email;

    });
  }
  function checkLogoutState(){
      FB.logout(function(response) {
          FB.Auth.setAuthResponse(null, 'unknown');
        });
      };
      function checkData()
      {
          return $.ajax({

              })
          }
</script>

我使用的是SpringMVC方法，完全基于JAVA，不使用任何xml文件。我搜索了很多，但没有得到任何解决方案
