I use this properties spring.zipkin.sender.type=rabbit spring.zipkin.base-url=http://zipkin-server:9411/

Answer 1

I implemented my own configuration class as;

@Slf4j
@Configuration
public class TracingReportToRabbitConfiguration {

// Custom configuration for a Zipkin RabbitMQ Sender instantiation

@Bean(value="zipkinSender")
Sender sender(@Value("${spring.rabbitmq.addresses}") String rabbitmqHostUrl,
              @Value("${spring.rabbitmq.queue:zipkin}") String zipkinQueue,
              @Value("${spring.rabbitmq.username}") String username,
              @Value("${spring.rabbitmq.password}") String password,
              @Value("${spring.rabbitmq.ssl.enabled:false}") boolean useSSL) throws KeyManagementException, NoSuchAlgorithmException {
....

which works for me.
