[SPRING] 원인 : java.lang.ClassNotFoundException : org.elasticsearch.transport.Netty3Plugin

원인 : java.lang.ClassNotFoundException : org.elasticsearch.transport.Netty3Plugin

나는 봄 부팅 2.0.3 릴리스를 사용하고 org.elasticsearch.client.Client를 인스턴스화하는 동안 문제가있다. 내 코드 :

Client client = new PreBuiltTransportClient(Settings.builder()
                .put("cluster.name", clustername)
                .build())
                .addTransportAddress(
new InetSocketTransportAddress(InetAddress.getByName(host), port)
);

이 코드는 다음과 같은 오류를줍니다.

org.elasticsearch : elasticsearch : 5.6.10 및 org.elasticsearch.client : client : 5.6.10을 사용합니다.

해결법

1. ==============================

   1.spring-boot-startter-data-elasticsearch 만 추가하면 모든 종속성이 만족되는 것은 아닙니다.

   spring-boot-startter-data-elasticsearch 만 추가하면 모든 종속성이 만족되는 것은 아닙니다.

   나머지 모든 종속성을 명시 적으로 정의해야합니다.

       <dependency>
           <groupId>org.elasticsearch.client</groupId>
           <artifactId>transport</artifactId>
           <version>${elasticsearch.version}</version>
       </dependency>
   
       <dependency>
           <groupId>org.elasticsearch.plugin</groupId>
           <artifactId>transport-netty4-client</artifactId>
           <version>${elasticsearch.version}</version>
       </dependency>
   

   부모를 선언했다면 대부분의 태그를 생략 할 수 있습니다.
