springboot-jwt

An Example Spring Boot Application for Securing a REST API with JSON Web Token (JWT)

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 1.5.3.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
H2 Database Engine - used for rapid prototyping and development, but not suitable for production at least in most cases. Go to www.h2database.com to learn more

To run the application

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

Build using maven goal: mvn clean package and execute the resulting artifact as follows java -jar springboot-jwt-0.0.1-SNAPSHOT.jar or
On Unix/Linux based systems: run mvn clean package then run the resulting jar as any other executable ./springboot-jwt-0.0.1-SNAPSHOT.jar

To test the application

First you will need the following basic pieces of information:

client: testjwtclientid
secret: XY7kmzoNzl100
Non-admin username and password: john.doe and jwtpass
Admin user: admin.admin and jwtpass
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:MaYzkSjmkzPC57L@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.eyJhdWQiOlsidGVzdGp3dHJlc291cmNlaWQiXSwidXNlcl9uYW1lIjoiYWRtaW4uYWRtaW4iLCJzY29wZSI6WyJyZWFkIiwid3JpdGUiXSwiZXhwIjoxNDk0NDU0MjgyLCJhdXRob3JpdGllcyI6WyJTVEFOREFSRF9VU0VSIiwiQURNSU5fVVNFUiJdLCJqdGkiOiIwYmQ4ZTQ1MC03ZjVjLTQ5ZjMtOTFmMC01Nzc1YjdiY2MwMGYiLCJjbGllbnRfaWQiOiJ0ZXN0and0Y2xpZW50aWQifQ.rvEAa4dIz8hT8uxzfjkEJKG982Ree5PdUW17KtFyeec",
  "token_type": "bearer",

  "scope": "read write",
  "jti": "0bd8e450-7f5c-49f3-91f0-5775b7bcc00f"
}`

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: curl http://localhost:8080/springjwt/cities -H "Authorization: Bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJhdWQiOlsidGVzdGp3dHJlc291cmNlaWQiXSwidXNlcl9uYW1lIjoiYWRtaW4uYWRtaW4iLCJzY29wZSI6WyJyZWFkIiwid3JpdGUiXSwiZXhwIjoxNDk0NDU0MjgyLCJhdXRob3JpdGllcyI6WyJTVEFOREFSRF9VU0VSIiwiQURNSU5fVVNFUiJdLCJqdGkiOiIwYmQ4ZTQ1MC03ZjVjLTQ5ZjMtOTFmMC01Nzc1YjdiY2MwMGYiLCJjbGllbnRfaWQiOiJ0ZXN0and0Y2xpZW50aWQifQ.rvEAa4dIz8hT8uxzfjkEJKG982Ree5PdUW17KtFyeec"
  
  The response will be: [ { "id": 1, "name": "Bamako" }, { "id": 2, "name": "Nonkon" }, { "id": 3, "name": "Houston" }, { "id": 4, "name": "Toronto" }, { "id": 5, "name": "New York" }, { "id": 6, "name": "Mopti" }, { "id": 7, "name": "Koulikoro" }, { "id": 8, "name": "Moscow" } ]
- 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" The result will be: [ { "id": 1, "username": "john.doe", "firstName": "John", "lastName": "Doe", "roles": [ { "id": 1, "roleName": "STANDARD_USER", "description": "Standard User - Has no admin rights" } ] }, { "id": 2, "username": "admin.admin", "firstName": "Admin", "lastName": "Admin", "roles": [ { "id": 1, "roleName": "STANDARD_USER", "description": "Standard User - Has no admin rights" }, { "id": 2, "roleName": "ADMIN_USER", "description": "Admin User - Has permission to perform admin tasks" } ] } ]
