I use Spring MVC and Spring Security for my project.. This using my own user data for authentication. But now i trying to integrate with Facebook. i have created app on Facebook means i got Client ID and client Secret.. I also read some questions in SO and some documents but still stuck...
i create controller to Login with Facebook :
import java.util.List;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
@RequestMapping("/login/")
public class LoginController {
String fb_app_id="my_client_id";
String redirect_url="localhost:8888";
String state="public_profile,email,user_friends";
String key="my_client_secret";
@RequestMapping("/facebook")
public String login( ModelMap model) {
String url="https://www.facebook.com/dialog/oauth/?"
+ "client_id=" + fb_app_id
+ "&redirect_uri=" + redirect_url
+ "&scope=email,publish_stream,user_about_me,friends_about_me"
+ "&state=" + key
+ "&display=page"
+ "&response_type=code";
return "redirect:"+url;
}
}
i think it works because when i try to connect, i can show my name with Javascript below:
function testAPI() {
console.log('Welcome! Fetching your information.... ');
FB.api('/me', function(response) {
console.log('Good to see you, ' + response.name + '.');
document.getElementById('status').innerHTML = 'Good to see you, ' +
response.name;
});
}
But i still confuse how to integrate it with Spring Security. If anyone have any examples i will appreciate...
This is my spring-security.xml

i have my own class to Authenticate to userdata with JPA...
package com.games.predictor.security;
import java.util.List;
import org.springframework.security.authentication.BadCredentialsException;
import org.springframework.security.authentication.UsernamePasswordAuthenticationToken;
import org.springframework.security.authentication.dao.AbstractUserDetailsAuthenticationProvider;
import org.springframework.security.core.AuthenticationException;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.core.userdetails.User;
import org.springframework.security.core.authority.SimpleGrantedAuthority;
import com.games.predictor.UserDAO;
public class AuthenticationProvider extends AbstractUserDetailsAuthenticationProvider
{
//private SecurityDao securityDao;
@Override
protected UserDetails retrieveUser(String username,
UsernamePasswordAuthenticationToken authentication)
throws AuthenticationException
{
final String password = authentication.getCredentials().toString();
System.out.println(username+"===="+password);
//This line for validating user with database
boolean isValidUser = UserDAO.INSTANCE.isValidUser(username, password);
if (isValidUser)
{
final List<SimpleGrantedAuthority> authorities = UserDAO.INSTANCE.getAuthoritiesByUser(username);
//User u=new User(username,password,);
return new User(username, password, true, true, true, true, authorities);
}
else
{
authentication.setAuthenticated(false);
throw new BadCredentialsException("Username/Password does not match for "
+ authentication.getPrincipal());
}
}
@Override
protected void additionalAuthenticationChecks(UserDetails arg0,
UsernamePasswordAuthenticationToken arg1)
throws AuthenticationException {
// TODO Auto-generated method stub
}
}
I did some research in last few days but still stuck.
