I am trying to use Json-B with Spring Boot version: 2.3.1

Json-b

I've a POST endpoint below. I want to get access to the raw JSON that is being sent inside the handler method. Ideally this would either be as a String or converted to a Map. The data in the JSON could vary and I don't want to cast it to a specific class as is done in the Pokemon example.

I've tried two methods below, one trying to access the data from the request object and the second using a handler with String.class. The first logs the following error "SEVERE org.eclipse.yasson.internal.Unmarshaller Thread[nioEventLoopGroup-3-2,10,main]: Unexpected char 39 at (line no=1, column no=1, offset=0)".

The second prints the first part of the JSON "{key1:value1,".

I have an application based on Wildfly 15, which uses Yasson to serialize entities in REST requests. I use the javaee-api 8.0.1 and created a ContextResolver for configuring the date serialization format like in https://stackoverflow.com/a/56300246/584532.

I'm converting a JAXB application to JSON-B and I've run into an issue while trying to deserialize a Java enum using a custom JsonbDeserializer inside one of my tests.

The original JSON I need to deserialize contains ints referencing the enum's constants. Therefore my custom JsonbDeserializer needs to take the int and return the enum constant with the matching ordinal. It looks like this:

I'm using JSON-B (yasson implementation) and I'm receiving data for an object with a field like this

I am trying to Export the following Entities with JSONB:

I'm using Jackson 2 with Payara 4 and I would liked to use Jackson 2 in Payara 5.

Using JAX-RS, I also would like to avoid changing annotations and so on...

In Payara 5 the default Jsonb provider is Yasson. Any ideas to disable it and use Jackson instead? All comments/ideas are welcome :-)

NB: Yasson is very interesting but handle abstract class or interface serialization/deserialization is a little more complex than putting a Jackson annotation. My current understanding is that it requires to implement a JsonbSerializer/Deserializer but actually the serializer/deserializer is only available on field/method (an issue is opened for class, which will be very helpful). Anyway, migrating to Yasson will mean implementing many serializer/deserializer as required (for entities and of course collections) but I guess it's a hard stuff.

I have using Jersey so far and I am doing my first implementation with JSON-B.

I am using Payara, so I working with Jersey and Yasson. I had an issue, because the serialized dates would always contain the "[UTC]" suffix.

I have managed to use an annotation on my date property, in my DTO. But I would like to configure that globally (in the JAX-RS application config?), instead of repeating myself on every date property. Is that possible? I haven't found anything so far...

Side question: I assume that it is possible to get rid of this "[UTC]" suffix, since it breaks all clients trying to parse the date. Any idea?

When including a not-so-recent version of Guava (20.0) in my Quarkus (0.19.1) application via a third-party lib, at runtime (mvn compile quarkus:dev), I get the following exception:
