I agree with @Marco around the java/maven options posted & I often use the following to build & test spring boot apps via maven:

mvn clean package

mvn -DENV_VAR_1=<val1> \
  -DENV_VAR_2=<val2> \
  -DENV_VAR_3=<val3> \
  spring-boot:run

However, I recommend using a docker file for spring boot applications using 'Dockerfile' (base image with entry point and run 'java -jar /app.war' command), 'docker-compose.yml' (with environment section that maps env vars after assigning ports), & '.env' file that holds environment variables/values only for local runs.

docker-compose.yml

services:
  service_name:
    image: app_name
    ports:
      - "8080:8080"
    environment:
      ENV_VAR_1: ${ENV_VAR_1}
      ENV_VAR_2: ${ENV_VAR_2}
      ENV_VAR_3: ${ENV_VAR_3}

.env file contents:

ENV_VAR_1=<val1>
ENV_VAR_2=<val2>
ENV_VAR_3=<val3>

Run steps via local docker desktop environment.

docker image build -t <app_name> .
docker compose up -d
docker logs <container> -f
