Spring云流汇合架构注册表无法正常工作

Question

以下代码不适用于汇合架构注册表。它没有给出模式注册表URL的连接超时错误。

消费者配置

@SpringBootApplication
@EnableBinding(Sink.class)
@EnableSchemaRegistryClient
public class ConsumerApplication {

    private final Log logger = LogFactory.getLog(getClass());

    public static void main(String[] args) {
        SpringApplication.run(ConsumerApplication.class, args);
    }

    @StreamListener(Sink.INPUT)
    public void process(Sensor data) {
        logger.info(data);
    }

    @Configuration
    static class ConfluentSchemaRegistryConfiguration {
        @Bean
        public SchemaRegistryClient schemaRegistryClient(@Value("${spring.cloud.stream.schemaRegistryClient.endpoint}") String endpoint){
            ConfluentSchemaRegistryClient client = new ConfluentSchemaRegistryClient();
            client.setEndpoint("http://localhost:8081");
            return client;
        }
    }
}

配置看起来像这样

spring:
  cloud:
    stream:
      bindings:
        input:
          destination: sensor-topic
      schemaRegistryClient:
        endpoint: http://localhost:8081
      schema:
        avro:
          schema-locations: classpath:avro/sensor.avsc
server.port: 9999

制作人配置

下面是放置消息的生产者配置，它无法连接到架构注册表

spring:
  cloud:
    stream:
      bindings:
        output:
          contentType: application/*+avro
          destination: sensor-topic
      schemaRegistryClient:
        endpoint: http://localhost:8081
      schema:
        avro:
          schema-locations: classpath:avro/sensor.avsc
server.port: 9009

下面的

是生产者配置

@SpringBootApplication
@EnableBinding(Source.class)
@EnableSchemaRegistryClient
@RestController
public class Producer1Application {

    @Autowired
    private Source source;

    private Random random = new Random();

    public static void main(String[] args) {
        SpringApplication.run(Producer1Application.class, args);
    }

    @RequestMapping(value = "/messages", method = RequestMethod.POST)
    public String sendMessage() {
        source.output().send(MessageBuilder.withPayload(randomSensor()).build());
        return "ok, have fun with v1 payload!";
    }

    private Sensor randomSensor() {
        Sensor sensor = new Sensor();
        sensor.setId(UUID.randomUUID().toString() + "-v1");
        sensor.setAcceleration(random.nextFloat() * 10);
        sensor.setVelocity(random.nextFloat() * 100);
        sensor.setTemperature(random.nextFloat() * 50);
        return sensor;
    }

    //Another convenience POST method for testing deterministic values
    @RequestMapping(value = "/messagesX", method = RequestMethod.POST)
    public String sendMessageX(@RequestParam(value="id") String id, @RequestParam(value="acceleration") float acceleartion,
                               @RequestParam(value="velocity") float velocity, @RequestParam(value="temperature") float temperature) {
        Sensor sensor = new Sensor();
        sensor.setId(id + "-v1");
        sensor.setAcceleration(acceleartion);
        sensor.setVelocity(velocity);
        sensor.setTemperature(temperature);
        source.output().send(MessageBuilder.withPayload(sensor).build());
        return "ok, have fun with v1 payload!";
    }

    @Configuration
    static class ConfluentSchemaRegistryConfiguration {
        @Bean
        public SchemaRegistryClient schemaRegistryClient(@Value("${spring.cloud.stream.schemaRegistryClient.endpoint}") String endpoint){
            ConfluentSchemaRegistryClient client = new ConfluentSchemaRegistryClient();
            client.setEndpoint(endpoint);
            return client;
        }
    }
}
