If you are looking forward to start a new spring project, you may need to do a lot of boilerplate stuff, before you can get into your application logic.

Here I’ve a skeleton project to help you out with it. You just need to clone it and start writing your application logic.

It’s a skeleton project with lots of features implemented by default.

Authentication Flow (Some basic implemented api’s)

Registration

Before you can register a user with a phone number you need to verify phone.

POST /api/v1/register/verifyPhone?phone=01610226163 HTTP/1.1

That phone number will get a token (validity for 2 minutes, can send another token request after two minutes)

Then you can send a request for registering user with that token

POST /api/v1/register?otp=449183 HTTP/1.1
Host: localhost:8080
Content-Type: application/json
cache-control: no-cache
{
	"name": "Sayem Hossain",
	"email" : "[email protected]",
	"phone" : "01610226163",
	"password": "123456"
}

If registration is successful it will give you a response like below, so that you can instantly log user in.

{
    "access_token": "eea1a168-36d3-41ae-963b-e5156cb678ed",
    "token_type": "bearer",
    "refresh_token": "cc936718-e938-4143-b742-b7d0575c49a2",
    "expires_in": 19999,
    "scope": "read trust write",
    "phone": "01610226163",
    "name": "Sayem Hossain",
    "id": 10,
    "authorities": [
        {
            "authority": "ROLE_USER"
        }
    ],
    "username": "01610226163"
}

Bind this response to your defined UserAuth object and this object should be your authentication

Login

GET /api/v1/login?username=01610226163& password=123456& client_id=client_id& client_secret=client_secret& grant_type=password HTTP/1.1
Host: localhost:8080
cache-control: no-cache

Response of login url will be same as registration response above (UserAuth) if login succeed.

Refresh Token

The validity duration of access token is 5000s. So if you find 401 response code in any request, refresh your access token

POST /api/v1/login?client_id=client_id& client_secret=client_secret& grant_type=refresh_token& refresh_token=cc936718-e938-4143-b742-b7d0575c49a2 HTTP/1.1
Host: localhost:8080
cache-control: no-cache
Postman-Token: 4826c898-6b31-4ccc-9551-f2c3d5c5bb01
