我想在开始生产和消费工作之前确保kafka服务器是否正在运行.它是在windows环境中,这是我的kafka服务器在eclipse中的代码...

Properties kafka = new Properties();
kafka.setProperty("broker.id", "1");
kafka.setProperty("port", "9092");
kafka.setProperty("log.dirs", "D://workspace//");
kafka.setProperty("zookeeper.connect", "localhost:2181");    
Option<String> option = Option.empty();
KafkaConfig config = new KafkaConfig(kafka);        
KafkaServer server = new KafkaServer(config, new CurrentTime(), option);
server.startup();

在这种情况下if (server != null)是不够的,因为它总是如此.那么有没有办法知道我的kafka服务器正在运行并为生产者做好准备.我有必要检查一下,因为它会导致丢失一些起始数据包.

谢谢.

我有一个使用 apache kafka-streams 的 Spring Boot 应用程序。我不使用 spring 云流。我添加了执行器健康检查端点。我是application.yml这样配置的：

management:
  health.db.enabled: false
  endpoints.web:
    base-path:
    path-mapping.health: /

当抛出运行时异常并且我的流被停止时，日志显示但运行状况检查状态为 UP。

2019-09-17 13:16:31.522 INFO 1 --- [ Thread-5] org.apache.kafka.streams.KafkaStreams : stream-client [lpp-model-stream-7e6e8fea-fcad-4033-92a4-5ede50de6e17] Streams client stopped complet伊利

如何将 kafka 流状态绑定到健康检查端点？
