CustomSocialMediaApp

Maven based Java MVC Web Project containing REST APIs for functionalities drawing few similarities with LinkedIn and Twitter; SQLite is used as a backend database which is attached with the project itself

How to deploy

For building an eclipse web project :

Do run this command in a folder where CustomSocialWebApp is placed.

[cutompath]$ mvn eclipse:eclipse -Dwtpversion=2.0

How to run: Use a tool like POSTMAN or run in a browser to capture JSON based response

For example:

http://localhost:8080/CustomSocialMediaApp/API/app/v1.1/messages/users/1?messageContains=Renovat

http://localhost:8080/CustomSocialMediaApp/API/app/v1.1/followers/users/2

contextPath = http://localhost:8080/CustomSocialMediaApp/API/

Following are the (SocialAppController.java) controller methods with their mappings for each individual functionality:

1) public List findAllMessegesOfUserWithFolloweesByUserId

Retrieves list of messages or newsfeed posted by userId = 1 and its followees or people it is following.

Method URL Action: GET

contextPath + /app/v1.1/messages/users/1?messageContains=Renovat

2) public List findAllFollowersByUserId

Retrieves list of followers of userId =2

Method URL Action: GET

contextPath + /app/v1.1/followers/users/2

3) public List findAllFolloweesByUserId Retrieves list of people, to whom userId =2 is following

Method URL Action: GET

contextPath + /app/v1.1/followees/users/2

4) public void unfollowAnotherPerson

userId = 4 unfollows another user whose followId = 1

Method URL Action: GET

contextPath + /app/v1.1/users/unfollow?userId=4&followeeId=1

5) public void followAnotherPerson

userId = 4 starts following another user whose followId = 1

Method URL Action: GET

contextPath + /app/v1.1/users/follow?userId=4&followeeId=1

6) public int findShortestDistanceBetweenUsers

Find the minimum distance between userId = 3 and another user whose id = 6

Method URL Action: GET

contextPath + /app/v1.1/users/shortestdistance?sourceId=3&destinationId=6

Graph for followees for the userID =3 :

1 -> 4 -> 2

2 -> 3 -> 4

3 -> 1 -> 2

4 -> 5 -> 2

5 -> 6

6

So shortest path is via:

3 -> 1 -> 4 -> 5 -> 6

Each directly connected edge is 1 hop !

As we covered 4 hops: Hence shortest path distance = 4
