Springboot弹性搜索运行状况管理：ConnectException：连接被拒绝 [英] Springboot elastic search health management : ConnectException: Connection refused

问题描述

在我的spring yaml文件中：

In my spring yaml file:

spring:
  application:
    name: myApp
  elasticsearch:
    jest:
      uris: ["http://myelasticserver:9200"]
      multi-threaded: true
      read-timeout: 10000

management:
  health:
    elasticsearch:
      indices: ["one","two"]
      response-timeout: 1000
      enabled: true

实际上，Jest客户端可以被注入和使用而没有任何问题。但是以某种方式，运行状况检查始终会因以下错误而失败：

Thing is, the Jest client can be injected and used without any problem. But somehow, the health check always fails with this error:

Elasticsearch运行状况检查失败java.net.ConnectException：
连接被拒绝

Elasticsearch health check failed java.net.ConnectException: Connection refused

URL似乎是 http： //没有使用myelasticserver：9200 ，而运行状况检查则改为使用localhost：9200。

It seems like the URL "http://myelasticserver:9200" wasn't used, and health check use localhost:9200 instead.

有人知道我在做什么错吗？

Does anyone know what did I do wrong?

谢谢。

推荐答案

Spring boot elasticsearch需要知道连接到哪个端口（和主机）以进行健康检查。添加：

Spring boot elasticsearch needs to know to which port (and host) to connect for the health check. Add:

spring:
  elasticsearch:
    rest:
      uris: "myelasticserver:9200"
      #username: ""
      #password: ""

除了您已经拥有的配置。这是分开的，因为像我一样，许多人使用elasticsearch的（非http）端口9300进行实际搜索，而不是使用配置的一部分。我都没有management.health.elasticsearch。我对Elasticsearch的总体配置是：

This is in addition to the config you already have. This is separate because many people, like me, use the (non-http) port 9300 of elasticsearch for the actual searches instead of your part of the config. I neither have management.health.elasticsearch. My total config for elasticsearch is:

spring:
  elasticsearch:
    rest:
      uris: "myelasticserver:9200"
  data:
    elasticsearch:
      cluster-nodes: "myelasticserver:9300"
      cluster-name: "my-cluster-name"
