Spring Boot Oauth2 using JWT

An Example of Spring Boot Application for Securing a REST API with Oauth2 using JSON Web Token (JWT). JdbcTokenStore is used to save the token issued to the users
It supports multiple authentication providers LDAP and DB. First will check the DB and if the user doesn't exists in DB then it will check the LDAP which is configured. This application can be used as a seed to quick start your spring boot REST API project with a fully functional security module.

Main building blocks

Spring Boot 1.5.9.RELEASE go to http://docs.spring.io/spring-boot/docs/1.5.3.RELEASE/reference/htmlsingle/ to learn more about spring boot
JSON Web Token go to https://jwt.io/ to decode your generated token and learn more.

To run the application
Use one of the several ways of running a Spring Boot application. Below are just three options:

Build using maven goal: mvn clean package and execute the resulting artifact as follows java -jar springboot-jwt-1.0-SNAPSHOT.jar or
On Unix/Linux based systems: run mvn clean package then run the resulting jar as any other executable ./springboot-jwt-1.0-SNAPSHOT.jar

To test the application

First you will need the following basic pieces of information:

client: testjwtclientid
secret: XY7kmzoNzl100
Local DB
Non-admin username and password: john.doe and jwtpass
Admin user: admin.admin and jwtpass
LDAP
username and password: ben and benspassword
Example of resource accessible to all authenticated users: http://localhost:8080/springjwt/cities
Example of resource accessible to only an admin user: http://localhost:8080/springjwt/users

Generate an access token

Use the following generic command to generate an access token:

$ curl client:secret@localhost:8080/oauth/token -d grant_type=password -d username=user -d password=pwd

For this specific application, to generate an access token for the non-admin user john.doe, run:

$ curl testjwtclientid:XY7kmzoNzl100@localhost:8080/oauth/token -d grant_type=password -d username=john.doe -d password=jwtpass

You'll receive a response similar to below

     {
        "access_token": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJleHAiOjE1NDM2MDI2NjksInVzZXJfbmFtZSI6ImFkbWluLmFkbWluIiwiYXV0aG9yaXRpZXMiOlsiU1RBTkRBUkRfVVNFUiIsIkFETUlOX1VTRVIiXSwianRpIjoiYzU0OTUwOWMtOGE2Ni00MmM4LTk4ZDQtZTIxOGMwMmQxYmFiIiwiY2xpZW50X2lkIjoidGVzdGp3dGNsaWVudGlkIiwic2NvcGUiOlsicmVhZCIsIndyaXRlIl19.hltbUwoJN9IQRLEHs_RnJS_MBaVMMzp0CjRB6paVGpY",
        "token_type": "bearer",
        "refresh_token": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJ1c2VyX25hbWUiOiJhZG1pbi5hZG1pbiIsInNjb3BlIjpbInJlYWQiLCJ3cml0ZSJdLCJhdGkiOiJjNTQ5NTA5Yy04YTY2LTQyYzgtOThkNC1lMjE4YzAyZDFiYWIiLCJleHAiOjE1NDYxOTM3NjksImF1dGhvcml0aWVzIjpbIlNUQU5EQVJEX1VTRVIiLCJBRE1JTl9VU0VSIl0sImp0aSI6IjU4MTkzMTNmLTg0YTAtNGM1Mi05ZGNiLThiZWM1ZTcwNWI1NiIsImNsaWVudF9pZCI6InRlc3Rqd3RjbGllbnRpZCJ9.yvZmi5SyVmXpVEFwyE2H2lZ6VuP4ZMYQ8udnPtiWIIs",

        "jti": "c549509c-8a66-42c8-98d4-e218c02d1bab"
    }

Use the following command to validate an access token:

$ curl testjwtclientid:XY7kmzoNzl100@localhost:8080/oauth/check_token -d 'token=eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJleHAiOjE1NDM2MDI2NjksInVzZXJfbmFtZSI6ImFkbWluLmFkbWluIiwiYXV0aG9yaXRpZXMiOlsiU1RBTkRBUkRfVVNFUiIsIkFETUlOX1VTRVIiXSwianRpIjoiYzU0OTUwOWMtOGE2Ni00MmM4LTk4ZDQtZTIxOGMwMmQxYmFiIiwiY2xpZW50X2lkIjoidGVzdGp3dGNsaWVudGlkIiwic2NvcGUiOlsicmVhZCIsIndyaXRlIl19.hltbUwoJN9IQRLEHs_RnJS_MBaVMMzp0CjRB6paVGpY&undefined='

Use the following command to refresh token:

$ curl -X POST testjwtclientid:XY7kmzoNzl100@localhost:8080/oauth/check_token -d 'grant_type=refresh_token&refresh_token=eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJ1c2VyX25hbWUiOiJqb2huLmRvZSIsInNjb3BlIjpbInJlYWQiLCJ3cml0ZSJdLCJhdGkiOiJkYmZiYjI5Mi00NjMyLTQ5ODEtYThjMi0xZjYxNGQ5MjgyY2QiLCJleHAiOjE1NDYxODk3NjcsImF1dGhvcml0aWVzIjpbIlNUQU5EQVJEX1VTRVIiXSwianRpIjoiZjdhZDNiYWMtOTViYy00ZTZhLTkzYTQtODg0NzQ0Y2M5ODc1IiwiY2xpZW50X2lkIjoidGVzdGp3dGNsaWVudGlkIn0.VD9AJeK6555CYk5DaKj7ik81c81C6gPypNhTlEs6bsY&undefined='

Use the token to access resources through your RESTful API

Access content available to all authenticated users Use the generated token as the value of the Bearer in the Authorization header as follows:

http://localhost:8080/springjwt/cities -H "Authorization: Bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJhdWQiOlsidGVzdGp3dHJlc291cmNlaWQiXSwidXNlcl9uYW1lIjoiYWRtaW4uYWRtaW4iLCJzY29wZSI6WyJyZWFkIiwid3JpdGUiXSwiZXhwIjoxNDk0NDU0MjgyLCJhdXRob3JpdGllcyI6WyJTVEFOREFSRF9VU0VSIiwiQURNSU5fVVNFUiJdLCJqdGkiOiIwYmQ4ZTQ1MC03ZjVjLTQ5ZjMtOTFmMC01Nzc1YjdiY2MwMGYiLCJjbGllbnRfaWQiOiJ0ZXN0and0Y2xpZW50aWQifQ.rvEAa4dIz8hT8uxzfjkEJKG982Ree5PdUW17KtFyeec"

Access content available only to an admin user As with the previous example first generate an access token for the admin user with the credentials provided above then run:

curl http://localhost:8080/springjwt/users -H "Authorization: Bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJhdWQiOlsidGVzdGp3dHJlc291cmNlaWQiXSwidXNlcl9uYW1lIjoiYWRtaW4uYWRtaW4iLCJzY29wZSI6WyJyZWFkIiwid3JpdGUiXSwiZXhwIjoxNDk0NDU0OTIzLCJhdXRob3JpdGllcyI6WyJTVEFOREFSRF9VU0VSIiwiQURNSU5fVVNFUiJdLCJqdGkiOiIyMTAzMjRmMS05MTE0LTQ1NGEtODRmMy1hZjUzZmUxNzdjNzIiLCJjbGllbnRfaWQiOiJ0ZXN0and0Y2xpZW50aWQifQ.OuprVlyNnKuLkoQmP8shP38G3Hje91GBhu4E0HD2Fes"
