引起原因:java.lang.ClassNotFoundException:org.elasticsearch.transport.Netty3Plugin [英] Caused by: java.lang.ClassNotFoundException: org.elasticsearch.transport.Netty3Plugin

问题描述

我正在使用Spring Boot 2.0.3 Release，实例化org.elasticsearch.client.Client时遇到问题.我的代码:

I'm using Spring Boot 2.0.3 Release and i have problem while instantiating org.elasticsearch.client.Client. My code:

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

此代码给我错误:

我使用org.elasticsearch:elasticsearch:5.6.10和org.elasticsearch.client:client:5.6.10.

推荐答案

仅添加spring-boot-starter-data-elasticsearch并不能满足所有依赖关系.

Not all dependencies are satisfied by only adding spring-boot-starter-data-elasticsearch.

有必要明确定义所有剩余的依赖项:

It's necessary to explicitly define all remaining dependencies:

    <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>

如果您声明了父母，很可能会省略<version>标签.

If you've declared a parent, most likely <version> tag can be omitted.
