PrintCodeWebService (PC-WS)

Main service for the BFH AppTrans exercise.

Live demo (with mock external systems) at https://bfh-pcws-mock.herokuapp.com/swagger-ui/index.html

See also https://github.com/SamuelBucheliZ/bfh-apptrans-exercise/blob/master/README.md

Versions

PC-WS is known to work with the following versions

  • Java: 11
  • Tomcat: 9
  • PostgreSQL: 10

Installation

The relevant artifacts can be found here https://github.com/SamuelBucheliZ/bfh-pcws/releases/tag/latest-war

  1. Set up database using setup_db.sql.
  2. Set up cronjob to run transfer_logs.sh every minute.
  3. Deploy pcws.war in Tomcat.

Note: PC-WS provides a "mock" configuration (see below) which allows to run it in a demo mode without need for a database or external systems. This can be used to initially test the Tomcat setup, i.e., to directly start with step 3 above.

Configuration

The PrintCode-WebService can be configured using the following environment variables

  • SPRING_PROFILES_ACTIVE: Either real (to use the actual external services and database) or mock (to use mocked services). For the exercise, eventually, the real configuration must be used.
  • PCWS_DATALOG_DIRECTORY: Absolute path to the directory the service should write the datalogs into, e.g., /datalogDirectory.
  • PCWS_ACCOUNT_SERVICE_URL: URL of the account service, you can use https://bfh-paketblitz-account-service.herokuapp.com.
  • PCWS_DATASOURCE_JDBC_URL: JDBC URL of the database, this has the form jdbc:postgresql://<hostname>:<port>/<database-name>.
  • PCWS_DATASOURCE_USERNAME and PCWS_DATASOURCE_PASSWORD: Credentials to access the database.

The shell script to transfer the logs can be configured using the following environment variables

  • PCWS_DATALOG_DIRECTORY: Location of the datalog files to send.
  • PCWS_DATALOG_SERVICE_URL: URL of the datalog service, you can use https://bfh-paketblitz-datalog-service.herokuapp.com.
