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

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:

  1. 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.eyJhdWQiOlsidGVzdGp3dHJlc291cmNlaWQiXSwidXNlcl9uYW1lIjoiYWRtaW4uYWRtaW4iLCJzY29wZSI6WyJyZWFkIiwid3JpdGUiXSwiZXhwIjoxNDk0NDU0MjgyLCJhdXRob3JpdGllcyI6WyJTVEFOREFSRF9VU0VSIiwiQURNSU5fVVNFUiJdLCJqdGkiOiIwYmQ4ZTQ1MC03ZjVjLTQ5ZjMtOTFmMC01Nzc1YjdiY2MwMGYiLCJjbGllbnRfaWQiOiJ0ZXN0and0Y2xpZW50aWQifQ.rvEAa4dIz8hT8uxzfjkEJKG982Ree5PdUW17KtFyeec",
  "token_type": "bearer",

  "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" } ] } ]
