• Spring Data JPA. Persist data in SQL stores with Java Persistence API using Spring Data and Hibernate.
• PostgreSQL Driver. A JDBC and R2DBC driver that allows Java programs to connect to a PostgreSQL database using standard, database independent Java code.
• Spring Security. Highly customizable authentication and access-control framework for Spring applications.

Dependencies

• Maven Project
• Java 16
• Spring Boot 2.5.3
• PostgreSQL via Homebrew preferably

• Clone the project locally

    $ git clone https://github.com/urbanbigdatacentre/WPD-Auth.git

    $ cd WPD-Auth

• Start the PostgreSQL and run the scripts to create the database and get the load data.

  $ brew services start postgresql
  $ psql postgres
  postgres=# \conninfo
  postgres=# CREATE DATABASE wpdauth;
  postgres=# \c wpdauth
  wpdauth=# CREATE SCHEMA auth;
  wpdauth=# CREATE EXTENSION "uuid-ossp";  
  wpdauth=# \i db/ddl.sql
  wpdauth=# \i db/sys_config.sql
  wpdauth=# create user uwpdauth;
  wpdauth=# alter user uwpdauth with encrypted password '<your really secure password>';
  wpdauth=# GRANT USAGE ON SCHEMA auth TO uwpdauth; 
  wpdauth=# GRANT ALL PRIVILEGES ON ALL TABLES IN SCHEMA auth TO uwpdauth;
  wpdauth=# GRANT ALL PRIVILEGES ON ALL SEQUENCES IN SCHEMA auth TO uwpdauth;
  wpdauth=# \q

• Make sure the load mode ran successfully as described in the load folder

• Install dependencies

  $ mvn install

• Run the project

  $ mvn spring-boot:run

• Run the project as a service most likely in a production environment (mind the '&' character at the end)

  $ mvn spring-boot:run &

How to run this project

Navigate to http://localhost:8080/swagger-ui.html in your browser to check everything is working correctly. You can change the default port in the application.properties file.

• Make a GET request to /users/me to check you're not authenticated. You should receive a response with a 403 with an Access Denied message since you haven't set your valid JWT token yet.

$ curl -X GET http://localhost:8080/users/me

• Make a POST request to /users/signin with the default admin user we programatically created to get a valid JWT token

$ curl -X POST 'http://localhost:8080/users/login?username=admin&password=admin'

• Add the JWT token as a Header parameter and make the initial GET request to /users/me again

$ curl -X GET http://localhost:8080/users/me -H 'Authorization: Bearer <JWT_TOKEN>'

• You should get a similar response to this one, meaning that you're now authenticated
