There are a few options to run the application (from more flexible to least)

  1. You can just use the SpringBoot run functionality that is default in IntelliJ or SpringTools in Eclipse.

  2. Start the service with Maven.

    mvn spring-boot:run -Dspring.profiles.active=local

  3. Package the jar file and run it

mvn clean package
java -jar ./target/ads-service-exec.jar --spring.profiles.active=local

  "description": "TOYOTA",
  "price": 300000.0,
  "owner": "Hello",
  "status": "LIVE"
}

JWT token algo

{
  "alg": "RS256",
  "typ": "JWT"
}
