方法不存在：org.elasticsearch.client.requestoptions $ builder.setRequestConfig（lorg/apache/http/client/client/config/requestconfig;）

Question

我正在创建带有Spring Boot 2.3.4的Hibernate Search 6应用程序时，

我在尝试构建应用程序时面临此错误 -

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>

让我知道是否缺少某些内容。

Answer 1

这一切都在此处解释： https://docs.jboss.org/hibernate/stable/search/reference/reference/en-us/html_single/#gettingstarted-framework-framework-spring-spring-boot-boot-boot-depperency-verned-versency-versions

基本上，Spring Boot是管理您的依赖关系，并且正在迫使Elasticsearch客户端的较旧版本。您需要将其强制回到Hibernate搜索期望版本（一个较新的版本，7.16.x）。

---

只是为了澄清，这与我在其他答案中提到的Elasticsearch Server版本无关。这严格来说是关于您的客户的。

Answer 2

这可能是由于Elasticsearch依赖性不兼容的版本。来自看来您似乎需要7.10或7.16，但是您具有7.6依赖关系。还要检查服务器版本以确保。

Answer 3

Hibernate-Search-Backend-elasticsearch

在内部取决于 elasticsearch-rest-client-7.6.2.jar

和该方法

org.elasticsearch.client.requestoptions $ builder.setRequestConfig（lorg/apache/http/client/client/configert/requestconfig;）lorg/elasticsearch/client/client/requestoptions $ builder;

它试图找到的是在低级客户端的以后版本中。

临时解决方案将排除7.6.2，并包含最新版本的 elasticsearch-rest-client-7.6.2.2.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>

包括，

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

由于这是临时的，我不确定这是否可靠。
如果有更好的解决方案，请让我知道。
