1. First of all we need to create an account on https://apps.twitter.com and then Create New app in twitter developer account.

2. After that you will get App Id and App Secret

2. Integrate Twitter Dependencies in pom.xml file

       
           org.springframework.boot
           spring-boot-starter-social-twitter

3.Integrate Twitter Credential in app.properties

           spring.social.twitter.appId=
           spring.social.twitter.appSecret=

4.Integrate Twitter Signup Integration in your code

Get generated App Id ,App Secret,Consumer key & Consumer sceret from Key and Access Tokens tab in your created application. Set App Id ,App Secret,Consumer key & Consumer sceret in your appliction config file.package com.oodles.knitwallet.config.

4.1 TwitterConfig.java

         
import org.springframework.stereotype.S ervice;
import twitter4j.Twitter;
import twitter4j.TwitterFactory;
import twitter4j.conf.ConfigurationBuilder;
@Service
public class TwitterConfig {
    public Twitter twitterconfig(){
        ConfigurationBuilder cb = new ConfigurationBuilder();
        cb.setDebugEnabled(true)
        .setOAuthConsumerKey("ZPopwIvHYA6w92Z4WG2meQZxZ")
        .setOAuthConsumerSecret("6Z7NxDSRRBRjpsWjapozB9w5wM2eqje7F2hCUJovTkUxcGIFt1")
        .setOAuthAccessToken("849830219095658496-YAtZIF5AzinNZHXb7IX1LIOBM1ofybk")
        .setOAuthAccessTokenSecret("MGvKa1EQ10HWjyLWfewrplyBT1vt687vkCyaIt9pm4Grs");
         TwitterFactory tf = new TwitterFactory(cb.build());
         Twitter twitter = tf.getInstance();
        return twitter;   }
}

4.2 Create Twitter Controller TwitterController.java

public class Twittercontroller {
    @Autowired
    private UserService userService;
    @Autowired
    UserRepository userRepository;
    @Autowired
    private MessageService messageService; 
 /*This method is used to validate twitter token
     * @param socialAuthToken
     * @param userDetail
     * @return boolean
     * @throws IOException 
     * @throws AuthenticationException 
     */
    @RequestMapping(value = UrlMapping.TWITTER_LOGIN, method = RequestMethod.POST)
    ResponseEntity

4.3 Create Service Class Twitter Service

public String twitter_login(User userr) throws InvalidIdException
     {
         String token=null;
        if(userRepository.findBytwitterId(userr.getTwitterId())==null){
       //configuration of twitter api
            Twitter twitter=TwitterConfig.twitterconfig();
             try {
                   Long id = twitter.getId();
                   System.out.println("id is "+id);
                   if (id.equals(userr.getTwitterId()))
                   {  UserServiceGeneralise.User_Record(userr);
                       token = UserServiceGeneralise.Verification_Registration(userr);

                   } else
                   {
                       throw new InvalidIdException(messageService.getMessage(Message.USER_Id_ERROR));
                   }
                      
             }    
             catch (TwitterException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }        
             return token;
        }else  {
             token=UserServiceGeneralise.Verification_Auth(userr);
             return token;
        }   
   }

5.Run API On Postman
