Elasticsearch TransportClient NetworkPlugin NoClassDefFoundError [英] Elasticsearch TransportClient NetworkPlugin NoClassDefFoundError

问题描述

我期待在Spring Boot Web应用程序中集成Elasticsearch。这是我的配置，创建我的运输客户端：

  @Configuration 
 public class ElasticsearchConfig {
 
私人TransportClient客户端; 
 
 @Bean 
 public TransportClient client（）throws UnknownHostException {
 
设置设置= Settings.builder（）
 .put（client.transport 
 .put（client.transport.sniff，false）
 .put（transport.tcp.compress，true）
 .put（cluster .name，clusterName）
 .put（xpack.security.transport.ssl.enabled，true）
 .build（）; 
 
 client = new PreBuiltTransportClient（settings）; 
 
 client.addTransportAddress（new InetSocketTransportAddress（InetAddress.getByName（localhost），9300））; 
 
返回客户端; 
} 
  

当我启动项目我收到以下错误，我不知道为什么：

  java.lang.ClassNotFoundException：org.elasticsearch.plugins.NetworkPlugin 
  / pre> 
 
 
我忘了添加依赖关系吗？
  ;依赖性> 
< groupId> org.springframework.data< / groupId> 
< artifactId> spring-data-elasticsearch< / artifactId> 
< / dependency> 
<依赖关系> 
< groupId> org.elasticsearch.client< / groupId> 
< artifactId> transport< / artifactId> 
< version> 5.1.1< / version> 
< / dependency> 
  
希望你能帮助我
解决方案
我只是偶然发现同样的问题。似乎Elasticsearch文档不完整。除了运输客户端依赖，您还需要添加弹性搜索依赖关系：
 < dependency> 
< groupId> org.elasticsearch< / groupId> 
< artifactId> elasticsearch< / artifactId> 
< version> 5.1.1< / version> 
< / dependency> 
  
您还需要log4j依赖关系，但这在 Elasticsearch docs 。
 
I am looking forward to integrate Elasticsearch in a Spring Boot Web Application. Here is my configuration that creates my Transport Client:
@Configuration
public class ElasticsearchConfig {

private TransportClient client;

@Bean
public TransportClient client() throws UnknownHostException{

    Settings settings = Settings.builder()
            .put("client.transport.nodes_sampler_interval", "5s")
            .put("client.transport.sniff", false)
            .put("transport.tcp.compress", true)
            .put("cluster.name", "clusterName")
            .put("xpack.security.transport.ssl.enabled", true)
            .build();

    client = new PreBuiltTransportClient(settings);

    client.addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("localhost"), 9300));

    return client;
}
When I start the Project I get following error and I don't know why:
java.lang.ClassNotFoundException: org.elasticsearch.plugins.NetworkPlugin
Did I forgot to add a dependency?
<dependency>
    <groupId>org.springframework.data</groupId>
    <artifactId>spring-data-elasticsearch</artifactId>
</dependency>
<dependency>
    <groupId>org.elasticsearch.client</groupId>
    <artifactId>transport</artifactId>
    <version>5.1.1</version>
</dependency>
Hope you can help me
解决方案
I just stumbled over the same problem. Seems that the Elasticsearch docs aren't complete. In addition to the transport client dependency, you need to also add the elasticsearch dependency:
<dependency>
    <groupId>org.elasticsearch</groupId>
    <artifactId>elasticsearch</artifactId>
    <version>5.1.1</version>
</dependency>
You'll also need the log4j dependency, but that is clearly stated in the Elasticsearch docs.
