You could refer to https://skywalking.apache.org/docs/skywalking-java/next/en/setup/service-agent/java-agent/java-plugin-development-guide/ to develop own plugins . It's easy to collect method return value at InstanceMethodsAroundInterceptor#afterMethod method

Another option is through returnedObj in the Tag annotation
