Example using React (with Apollo) to make GraphQL call to Spring Boot Data JPA backed by Oracle via UCP

See soon to be released blog under: https://blogs.oracle.com/authors/paulparkinson

Instructions

1. cd spring-data-jpa-graphql-ucp-oracle
2. Modify src/main/resources/application.properties to set values for spring.datasource.url, spring.datasource.username, and spring.datasource.password
3. Run mvn clean install
4. Run java -jar target/spring-data-jpa-graphql-oracle-0.0.1-SNAPSHOT.jar
5. (In a separate terminal/console) cd react-graphql
6. Run yarn add @apollo/client graphql (this is only necessary once for the project)
7. Run npm run build
8. Run npm start

A browser window should open to http://localhost:3000/ which is a React app that will use Apollo to make a GraphQL query against a Spring Boot service running on localhost:8080 which in turn uses JPA to query an Oracle database via a connection obtained from UCP.
