启动方法初始化异常Elasticsearch 7.8.0

Question

使用java高级rest客户端，当我们调用getMapping进行索引或创建以下索引函数时，每次都会生成错误。几乎所有与索引相关的调用都会生成此异常

我正在使用以下环境

弹性搜索-7.8.0。openJDK-11和14，JDK 1.8elasticsearch-rest-high-level-client-7.8.0.jar及其在pom.xml中的依赖关系操作系统：尝试了Windows 10和Linux Mint

Answer 1

我收到了同样的错误，我发现httpcore版本不正确。我喜欢这个

<dependency>
<groupId>org.elasticsearch.client</groupId>
<artifactId>elasticsearch-rest-high-level-client</artifactId>
<version>7.16.2</version>
</dependency>
<dependency>
<groupId>org.elasticsearch.client</groupId>
<artifactId>elasticsearch-rest-client</artifactId>
<version>7.16.2</version>
</dependency>
<dependency>
<groupId>org.elasticsearch</groupId>
<artifactId>elasticsearch</artifactId>
<version>7.16.2</version>
</dependency>
<dependency>
<groupId>org.apache.httpcomponents</groupId>
<artifactId>httpcore</artifactId>
<version>4.4.12</version>
</dependency>

Answer 2

更改pom.xml配置

这可能是因为你的弹性搜索休息高级客户端版本太高了。

<dependency>
<groupId>org.elasticsearch.client</groupId>
<artifactId>elasticsearch-rest-high-level-client</artifactId>
<version>7.2.1</version>
</dependency>

在我这样做之后，这是正常的

Answer 3

我遇到这种情况是因为与httpcore依赖项发生冲突，特别是httpcore和httpcore nio不兼容。深入研究您的弹性搜索rest客户端版本的pom，并使用与中相同的版本，或者将它们从其他依赖项中排除。
