elasticsearch 5.3.0 中的重大更改 java api

Question

我正在将我的 elasticsearch 从 2.3.4 升级到 5.3.0

下面是我的类路径中的 jar

elasticsearch-5.3.0.jar
HdrHistogram-2.1.6.jar

transport-5.3.0.jar
log4j-api-2.7.jar
log4j-core-2.7.jar
log4j-1.2-api-2.7.jar
spatial4j-0.6.jar

当我在做

client = new PreBuiltTransportClient(Settings.EMPTY)
            .addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("127.0.0.1"), 9300))

我得到以下异常

Java 版本 1.8

是否有人也面临同样的问题或知道我在这里遗漏了什么？

Answer 1

Elasticsearch 5.3 期待 NettyPlugin 版本 4 org.elasticsearch.transport.Netty4Plugin。您的类路径或两个版本中的版本很可能是错误的，而旧版本首先被抓取。

如果您为您的库生成依赖关系树，您会看到哪些版本被引入，然后可以 include/exclude right/wrong 版本。
