SpringBoot Auth demo REST APIs with GCP AppEngine

This project demonstrates how to use SpringBoot JWT token to secure your REST APIs

It also showcase how we can use springfox-swagger2 to document APIs

To use the code:
Refer to google documentation to create a cloud sql instance: https://cloud.google.com/sql/docs/mysql/create-instance

git clone git@github.com:abharku/SpringBootAuthentication.git

Update SpringBootAuthentication/src/main/resources/application.properties from cloud sql instance you have created

spring.cloud.gcp.sql.instance-connection-name.

spring.cloud.gcp.sql.database-name.

spring.datasource.username.

spring.datasource.password

Replace following properties in pom.xml in appengine-maven-plugin section

project-id

GCLOUD_SDK_PATH

How to setup GCP CLOUD SDK is explained at https://cloud.google.com/sdk/docs/install

To deploy to Appengine run below mvn command:

clean install appengine:deploy

Assuming that SDK is setup properly. If you want to run locally then make sure following environment variable is setup and pointing to a credential json file:

GOOGLE_APPLICATION_CREDENTIALS.

Use the token received from signin/Signup method and click the Authorize button on Swagger-ui

In the text box add

Bearer token (Replace token with token received)

After this you will be able to access get api/v1/users/{int} method which is the only method secured by auth header

A running version of the code is available below:
