Spring boot with Maven ? How to use pkl ? Help provide examples #2

Open arundotin opened 9 months ago

arundotin commented 9 months ago

I am following this instruction here https://pkl-lang.org/spring/current/usage.html to configure pkl for my spring boot app (using Maven build tool)

But this document has only instructions for Gradle build tool. For build tools other than grade, it is been asked there to use pkl-codegen-java dependency which when I use it gets in to conflict with pkl-spring dependency due to lot of duplicate classes

This is my maven dependency

<dependency>
  <groupId>org.pkl-lang</groupId>
  <artifactId>pkl-spring</artifactId>
  <version>0.15.0</version>
  <scope>compile</scope>
</dependency>

When i also add pkl-codegen-java

<dependency>
    <groupId>org.pkl-lang</groupId>
    <artifactId>pkl-codegen-java</artifactId>
    <version>0.25.2</version>
  </dependency>

Then i get this error

The instructions in the pkl documentation isn't clear. Any help on this please ?

Have raised the same question in Stackoverflow as well https://stackoverflow.com/questions/78087435/how-to-use-apple-pkl-for-spring-boot-wit-maven

@linux-china - I tried and moved up to one level - but the app is not working. I get NPE

Below is my pom.xml (i have added --generate-spring-boot argument also)

Below are the pkl files i have

AppConfig.pkl

module com.arun.adventures.flights.AppConfig

server: Server

class Server {
  endpoints: Listing<Endpoint>
}

class Endpoint {
  name: String
  port: UInt16
}

This is my application.pkl

amends "AppConfig.pkl"

server {
  endpoints {
    new {
      name = "endpoint1"
      port = 1234
    }
    new {
      name = "endpoint2"
      port = 5678
    }
  }
}

This is my generated class (if you notice Endpoint class doesn't have spring annotation)

This is my FlightsService.java

@Service
public class FlightsService {

    private final AppConfig.Server server;

    public FlightsService(AppConfig.Server server) {
        this.server = server;
    }

    public AppConfig.Server getServer() {
        return server;
    }

}

From my controller when i do System.out.println(flightsService.getServer());

This is the output i get

Server {
  endpoints = null
}
