Question

我在Elasticsearch中使用spring-boot。该项目是使用jhipster创建的。

pom.xml包含：

<parent>
  <artifactId>spring-boot-starter-parent</artifactId> 
  <groupId>org.springframework.boot</groupId>
  <version>1.4.0.RELEASE</version>
  <relativePath/>
</parent>

和

<dependency>
  <groupId>org.springframework.boot</groupId>
  <artifactId>spring-boot-starter-data-elasticsearch</artifactId>
</dependency>

在生产模式下，会发生以下错误：

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

如何解决此错误？

Answer 1

在开发资料中，JHipster使用嵌入式Elasticsearch。

在生产配置文件中，它默认尝试连接到本地群集，因此要么您未在本地计算机上安装Elasticsearch，要么尚未在application-prod.yml中配置正确的网址以连接到现有群集。

首先感谢GaëlMarziou。我在本地计算机上安装了Elasticsearch，但问题仍然存在。所以，这是我的application-prod.yml文件。

Answer 3

我在ElasticSearchConfiguration.java中更改了我的elasticTemplate方法并且工作正常。我只需添加以下行并将我的群集节点名称设置为＆＃34; Gibborim＆＃34;在Elasticsearch 2.0中。

Settings settings = Settings.settingsBuilder()
        .put("client.transport.sniff", true).put("name","Gibborim").put("cluster.name", "elasticsearch").put("network.host","127.0.0.1").build();

    client = TransportClient.builder().settings(settings).build().addTransportAddress(new InetSocketTransportAddress(new InetSocketAddress("127.0.0.1", 9300)));

Answer 4

如果您使用默认的elasticsearch配置运行jhipster项目，请确保您的elasticsearh服务器版本为1.7，因为jhipster java项目适用于此版本（在生产配置文件中）

在开发简介中存在一个我无法解决的问题
