Application configuration

SpringApplication will load properties from the application.yml file and add them to the Spring Environment.

Let's specify properties for our Spring application in the application.yml file:

    logging:
      level:
        org.springframework.web.servlet: INFO
    spring:
      datasource:
        platform: "postgis"
        driver-class-name: "org.postgis.DriverWrapper"
        url: "jdbc:postgresql_postGIS://localhost/geo"
        username: "postgres"
        password: "root"
     mvc:
          async:
            request-timeout: 1000000

Tasync request timeout is crucial because saving the message into the database takes time and the process is asynchronous and an event is triggered when it is saved. Here the response takes more time than normal to get back, hence we increase the request timeout.

The data-source properties (database) point to our PostGIS database: 

    url: "jdbc:postgresql_postGIS://localhost/YOUR_DATABASE_NAME"

Make sure to change YOUR_DATABASE_NAME to the name of your PostGIS database, also change the username and password based on your database credentials.
