Class OpenapiJacksonModule

java.lang.Object
com.fasterxml.jackson.databind.Module
com.google.genai.gaos.utils.OpenapiJacksonModule
All Implemented Interfaces:
com.fasterxml.jackson.core.Versioned
public class OpenapiJacksonModule extends com.fasterxml.jackson.databind.Module
A composite Jackson Module that registers all SDK-required Jackson customizations.

Register this with a custom ObjectMapper to enable full serialization support for SDK types. Bundles JavaTimeModule, Jdk8Module, and SDK strict deserializers, and applies the same feature flags used by JSON.getMapper():

  • Disables WRITE_DATES_AS_TIMESTAMPS (ISO-8601 date strings)
  • Disables FAIL_ON_UNKNOWN_PROPERTIES
  • Disables FAIL_ON_EMPTY_BEANS
  • Enables FAIL_ON_NULL_FOR_PRIMITIVES
  • Restricts field visibility to annotated fields only

 ObjectMapper myMapper = new ObjectMapper()
     .registerModule(new OpenapiJacksonModule());
 String json = myMapper.writeValueAsString(response);

Alternatively, use JSON.getMapper() to access the pre-configured SDK mapper directly.
