方法不存在：org.elasticsearch.client.RequestOptions$Builder.setRequestConfig(Lorg/apache/http/client/config/RequestConfig;)

Question

我正在使用 Spring Boot 2.3.4

创建 Hibernate Search 6 应用程序

我在尝试构建我的应用程序时遇到此错误 -

Description:

An attempt was made to call a method that does not exist. The attempt was made from the 
following location:

   org.hibernate.search.backend.elasticsearch.client.impl.ElasticsearchClientImpl.setPerRequestSocketTimeout(ElasticsearchClientImpl.java:198)

The following method did not exist:


org.elasticsearch.client.RequestOptions$Builder.setRequestConfig(Lorg/apache/http/client/config/RequestConfig;)Lorg/elasticsearch/client/RequestOptions$Builder;

The method's class, org.elasticsearch.client.RequestOptions$Builder, is available from the following locations:

jar:file:/C:/Users/pranali.rasal/.m2/repository/org/elasticsearch/client/elasticsearch-rest-client/7.6.2/elasticsearch-rest-client-7.6.2.jar!/org/elasticsearch/client/RequestOptions$Builder.class

The class hierarchy was loaded from the following locations:

org.elasticsearch.client.RequestOptions.Builder: 
file:/C:/Users/pranali.rasal/.m2/repository/org/elasticsearch/client/elasticsearch-rest-client/7.6.2/elasticsearch-rest-client-7.6.2.jar


Action:

Correct the classpath of your application so that it contains a single, compatible version of org.elasticsearch.client.RequestOptions$Builder

以下是我添加的依赖项-

        <dependency>
            <groupId>org.hibernate.search</groupId>
            <artifactId>hibernate-search-mapper-orm</artifactId>
            <version>6.1.5.Final</version>
        </dependency>

        <dependency>
            <groupId>org.hibernate.search</groupId>
            <artifactId>hibernate-search-backend-elasticsearch</artifactId>
            <version>6.1.5.Final</version>
        </dependency>

如果我遗漏了什么，请告诉我。

Answer 1

这可能是由于 elasticsearch 依赖项的版本不兼容。从 https://docs.jboss.org/hibernate/stable/search/reference/en-US/html_single/#getting-started-compatibility 看来您需要 7.10 或 7.16，但您有 7.6 依赖项。还要检查服务器版本以确保。

Answer 2

hibernate-search-backend-elasticsearch

内部依赖于elasticsearch-rest-client-7.6.2.jar

和方法

org.elasticsearch.client.RequestOptions$Builder.setRequestConfig(Lorg/apache/http/client/config/RequestConfig;)Lorg/elasticsearch/client/RequestOptions$Builder;

正在尝试在低级别客户端的更高版本中查找。

临时解决方案是排除 7.6.2 并包括最新版本 elasticsearch-rest-client-7.6.2.jar -

    <dependency>
        <groupId>org.hibernate.search</groupId>
        <artifactId>hibernate-search-backend-elasticsearch</artifactId>
        <exclusions>
            <exclusion>
                <groupId>org.elasticsearch.client</groupId>
                <artifactId>elasticsearch-rest-client</artifactId>
            </exclusion>
        </exclusions>
    </dependency>

并包括，

       <dependency>
            <groupId>org.elasticsearch.client</groupId>
            <artifactId>elasticsearch-rest-client</artifactId>
            <version>7.10.0</version>
        </dependency>

临时的，不知道靠谱不。如果有更好的解决方案，请告诉我。

Answer 3

这一切都在这里解释：https://docs.jboss.org/hibernate/stable/search/reference/en-US/html_single/#gettingstarted-framework-spring-boot-dependency-versions

基本上，Spring Boot 正在管理您的依赖项，它会强制使用旧版本的 Elasticsearch 客户端。您需要强制它回到 Hibernate Search 期望的版本（较新的版本，7.16.x）。

澄清一下，这与我在其他答案中提到的 Elasticsearch 服务器版本无关。这完全是关于您的客户的。
