-----------------------------------
Summary: Allow avro-maven-plugin to generate Java classes that
implement interfaces
Key: AVRO-2544
URL: https://issues.apache.org/jira/browse/AVRO-2544
Project: Apache Avro
Issue Type: Wish
Components: java
Affects Versions: 1.9.0
Reporter: Michael Snell
Currently Java code generated by the avro-maven-plugin implements the
org.apache.avro.specific.SpecificRecord interface, but there is no ability to
have the generated code implement additional interfaces, which would make it
possible to improve type-safety and readability.
Similar to the already existing @java-class annotation
([https://avro.apache.org/docs/current/idl.html#minutiae_annotations]) I
suggest adding a @java-implements annotation that could be added to a record
definition:
{code:java}
@java-implements("an.example.JavaInterface")
record AnExampleRecord {
...{code}
This would be used by the avro-maven-plugin when generating Java code such that
the result implements both SpecificRecord and the specified interface:
{code:java}
public class AnExampleRecord extends
org.apache.avro.specific.SpecificRecordBase implements
org.apache.avro.specific.SpecificRecord , an.example.JavaInterface{code}
