Elasticsearch 失败并出现 NoNodeAvailableException

Question

我正在运行这样的弹性搜索图像： docker-compose.yml

version: '2'
services:
  elasticsearch:
    image: elasticsearch:5.4
    ports:
      - "9200:9200"
      - "9300:9300"

我可以用 curl 检查它是否正在运行。

curl http://127.0.0.1:9200/_cluster/health

回复：

{"cluster_name":"elasticsearch","status":"green","timed_out":false,"number_of_nodes":1,"number_of_data_nodes":1,"active_primary_shards":0,"active_shards":0,"relocating_shards":0,"initializing_shards":0,"unassigned_shards":0,"delayed_unassigned_shards":0,"number_of_pending_tasks":0,"number_of_in_flight_fetch":0,"task_max_waiting_in_queue_millis":0,"active_shards_percent_as_number":100.0}

在应用程序中，我像这样配置 TransportClient：

@Bean(destroyMethod = "close")
    public TransportClient transportClient() throws UnknownHostException {
        return new PreBuiltTransportClient(Settings.EMPTY)
                .addTransportAddress(new InetSocketTransportAddress(
                        InetAddress.getByName("localhost"), 9300));
    }

然后我想检查一下：

@Autowired
private TransportClient client;
@GetMapping(value = "test")
    public Object test(){
        return client.admin().cluster().health(Requests
                .clusterHealthRequest())
                .actionGet();
    }

但异常失败：

org.elasticsearch.client.transport.NoNodeAvailableException: None of the configured nodes are available: [{#transport#-1}{_atMOwK5R5mgOXqAPJWvWg}{localhost}{127.0.0.1:9300}]

顺便说一句，我正在使用此依赖项：compile('org.elasticsearch.client:transport:5.4.0')

尝试使用 elasticsearch 而不是本地主机，因为这是您的容器名称，以防 Spring Boot 应用程序也在 docker 中运行
