Bartosz Gałek updated AVRO-4040:
--------------------------------
Description:
While generating a class from my Avro schema, the `getSpecificData` and
`getSchema` [methods are added automaticaly|#L180-L183]].
These methods are not defined in user schemas, which can be confusing.
It's particularly problematic when analyzing such a class (i.e., via reflection
or serialization).
Libraries like `Jackson`, `Gson`, or `Springdoc` should ignore these fields.
However, each library has its way of ignoring public fields/getters
(`@JsonIgnore`, `@Expose`).
The Avro class generator should allow other libraries to handle those "special"
methods/fields without introducing additional coupling to those libraries in
the Avro project, of course.
I suggest annotating those methods with `@AvroGeneratedMethod` (or existing
`@AvroGenerated`) to address this.
Any library that tries to do something with Avro-generated classes can be
configured to ignore those Avro-specific methods.
If this plan is ok for maintainers, I could try to make a pull request with my
team.
