Persi opened a new issue #6842: URL: https://github.com/apache/pulsar/issues/6842
**Is your feature request related to a problem? Please describe.** I am trying to use Pulsar Java client in a Spring Boot application and was able to produce and consume messages. I ran in trouble when sending messages with JSON content which contains fields of type OffsetDateTime. My Spring Boot application already uses the same JSON for it's REST API and can serialize and deserialize OffsetDateTime as "jackson-datatype-jsr310" is in my classpath. But the included version of Jackson in the Pulsar Java client, does not know this extension and instead fails while deserialization with erros like the following: ``` ... Caused by: org.apache.pulsar.shade.com.fasterxml.jackson.databind.exc.InvalidDefinitionException: Cannot construct instance of `java.time.OffsetDateTime` (no Creators, like default construct, exist): cannot deserialize from Object value (no delegate- or property-based Creator) ``` **Describe the solution you'd like** Could you provide a non-shaded version of the Pulsar Java client? This would be really helpful for Spring Boot integrations, as most Spring Boot applications already provide a global configured instance of Jackson ObjectMapper, which the Pulsar Java client could use, to use the same mapping settings as the rest of the application. **Describe alternatives you've considered** The JSONSchema class instanciates it's ObjectMapper as internal ThreadLocal which makes it unchangeble as well as unconfigurable. You could add the opportunity to provide an ObjectMapper instance, e.g. on pulsar client instanciation, which could be used by all producers and consumers created. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
