当我们为索引调用 getMapping 或在下面创建索引函数时使用 java-high-level-rest 客户端，每次都会生成错误。几乎所有与索引相关的调用都会产生此异常。

我正在使用以下环境

弹性搜索 - 7.8.0。openJDK - 11 和 14、JDK 1.8 elasticsearch-rest-high-level-client-7.8.0.jar 及其依赖项包含在 pom.xml 操作系统中：尝试了 Windows 10 和 Linux Mint。

我得到了同样的错误，我发现httpcore版本不正确。我这样的依赖

<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>

        </dependency>
        <dependency>

            <artifactId>httpcore</artifactId>
            <version>4.4.12</version>
        </dependency>

更改您的 pom.xml 配置

可能是您的 elasticsearch-rest-high-level-client 版本太高。

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

做完之后就正常了

由于与 httpcore 依赖项的冲突，我遇到了这个问题，特别是 httpcore 和 httpcore-nio 不兼容。深入研究您的 elasticsearch-rest-client 版本的 pom 并使用与那里相同的版本，或者将它们从您的其他依赖项中排除。
