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 three options:

  1. Build using maven goal:
    mvn clean package
    and execute the resulting artifact as follows
    java -jar springboot-jwt-0.0.1-SNAPSHOT.jar
    or
  2. 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
  3. Build and start as a Docker container. Instructions at: README

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
  1. Generate an access token

Use the following generic command to generate an access token:

$ curl client:[email protected]: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:[email protected]t: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",
  "expires_in": 43199,
  "scope": "read write",
  "jti": "0bd8e450-7f5c-49f3-91f0-5775b7bcc00f"
}`
  1. 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"
           }
         ]
       }
     ]
