start local single node crdb instance by running...

./up.sh

run the following to build and execute the test...

./mvnw clean spring-boot:run

the application automatically creates the database schema using JPA. A table called Aircraft will be created with the following sql...

CREATE TABLE public.aircraft (
  id UUID NOT NULL,
  location GEOMETRY NULL,
  CONSTRAINT "primary" PRIMARY KEY (id ASC),
  FAMILY "primary" (id, location)
)

once the database is created a simple insert of the geometry data type is completed.
