agoncal / agoncal-fascicle-quarkus Goto Github PK

In chapter 3.6 the native image returns an empty json with "curl http://localhost:8080/artists | jq"

I have added the annotation "@RegisterForReflection" to the Artist class, as described in the documentation https://quarkus.io/guides/writing-native-applications-tips#registering-for-reflection

The Json is then not empty anymore

I started building agoncal-fascicle-quarkus/getting-started project. The quarkus:dev and getting-started-1.0-SNAPSHOT-runner.jar works perfectly fine and getting following response for http://localhost:8080/artists

[
  {
    "first_name": "John",
    "last_name": "Lennon"
  },
  {
    "first_name": "Paul",
    "last_name": "McCartney"
  },
  {
    "first_name": "George",
    "last_name": "Harrison"
  },
  {
    "first_name": "Ringo",
    "last_name": "Starr"
  }
]

However, when I build the native image and run that JSON bodies are not returning correctly.
Steps:

1. Build native image using ./mvnw package -Pnative
2. Access URL using curl http://localhost:8080/artists | jq

Actual response:

[
  {},
  {},
  {},
  {}
]

Expected response:

[
  {
    "first_name": "John",
    "last_name": "Lennon"
  },
  {
    "first_name": "Paul",
    "last_name": "McCartney"
  },
  {
    "first_name": "George",
    "last_name": "Harrison"
  },
  {
    "first_name": "Ringo",
    "last_name": "Starr"
  }
]

agoncal/hello-fascicle image does not exist in dockerhub, therefore the deployment step in book Undestanding Quarkus fails...

quarkusio/quarkus#14066

At book page 345, Listing 277 is not "POJO with Bean Validation and JSON-B Annotations", it is the BookResource code.

Hi,

In page 76 of Understanding Quarkus you wrote:

Qualifiers let you choose between multiple implementations of an interface at development time.

I am wondering what to do if I need to choose between two implementations at runtime?

PS: The book is amazing.
