In a terminal window, change to the jdbcdemo directory, build, package, and run the application:

mvn clean package spring-boot:run

To use the service to insert data, you can use an application like Postman, or if you have curl installed, execute

curl -X POST -H "Content-Type: application/json" -d '{"type":"Chequing","status":"Active","balance":"777"}' http://localhost:8080/account

Retrieve a list of accounts:

curl -X GET -H "Content-Type: application/json" http://localhost:8080/accounts

Delete an account:

curl -X DELETE -H "Content-Type: application/json" http://localhost:8080/account/6367736797661010002

Log into your PCF instance, and verify your Org and Space by running the cf target command.

Create a user-provided service JSON configuration file with the following content, substituting your own values for each DB2_ parameter:

{
     "hostname": "DB2_HOST",
     "jdbcUrl": "jdbc:db2://DB2_HOST/DB2_SCHEMA?user=DB2_USER\u0026password=DB2_PASSWORD",
     "name": "DB2_SCHEMA",
     "password": "DB2_PASSWORD",
     "port": "DB2_PORT",
     "uri": "db2://DB2_HOST:DB2_PORT/DB2_SCHEMA?reconnect=true",
     "username": "DB2_USER"
}

Create the user-provided service in PCF:

cf cups jdbcdemo-db -p config.json

Examine the manifest.yml file, note that it will automatically bind to the service. Deploy your application from the jdbcdemo root directory:

cf push

Test the application using the same curl commands (or Postman) used for the local deployment above, just changing the app URL endpoint to match your application route.
