spring-oauth-jpa-demo

It is a demo project to configure OAuth2 authorization server with JWT token using Spring Boot 2, JPA, MySQL database and Gradle

Configuration

1. To configure this project you can generate you keystore file using following command :

   keytool -genkeypair -alias jwt -keyalg RSA -keypass password -keystore jwt.jks -storepass password

   

   Note: Windows user you can find keytool in JDK directory. It will generate jwt.jks which contains the Public and Private keys.

2. It is recommended to migrate above generated key to PKCS12. Execute the following command to generate PKCS12

   keytool -importkeystore -srckeystore jwt.jks -destkeystore jwt.jks -deststoretype pkcs12

3. Generate public key using following command

   keytool -list -rfc --keystore jwt.jks | openssl x509 -inform pem -pubkey

   You will get public key on console after executing the above command.

4. Copy from (including) -----BEGIN PUBLIC KEY----- to -----END PUBLIC KEY----- and save it in file public.key file. It will be used in resource server.
