java - NoSuchBeanDefinitionException:当我使用自动配置时，没有名为 'elasticsearchTemplate'的bean可用

Question

我想使用ElasticSearch和Spring Data。我添加了此依赖项:

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-elasticsearch</artifactId>
</dependency>
<dependency>
    <groupId>org.elasticsearch.client</groupId>
    <artifactId>elasticsearch-rest-high-level-client</artifactId>
</dependency>

我要使用自动配置。我遵循此文档:https://docs.spring.io/spring-boot/docs/current/reference/html/spring-boot-features.html#boot-features-connecting-to-elasticsearch-rest

If you have the org.elasticsearch.client:elasticsearch-rest-high-level-client 
dependency on the classpath, Spring Boot will auto-configure a RestHighLevelClient

我创建了存储库:

@Repository
public interface ArticleRepository extends ElasticsearchRepository<Article, String> {

    Page<Article> findByAuthorsName(String name, Pageable pageable);
}

我添加了它，但是现在可以使用了!

启动我的应用程序后出现错误:

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating 
bean with name 'articleRepository' defined in com.example.elasticsearch.repository.ArticleRepository defined in @EnableElasticsearchRepositories declared on Config: 
Cannot resolve reference to bean 'elasticsearchTemplate' while setting bean property 'elasticsearchOperations'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'elasticsearchTemplate' available
    at org.springframework.beans.factory.support.BeanDefinitionValueResolver.resolveReference(BeanDefinitionValueResolver.java:342)

但是为什么会这样呢？我想使用自动配置，我不想手动描述bean，正如在对stackoverflow的其他响应中所说的那样!

我使用Spring Boot 2.3.1.RELEASE和Java 11

编辑:

我的配置:

@Configuration
@EnableElasticsearchRepositories(basePackages = " com.example.elasticsearch.repository")
public class Config {
}

我的应用程序:

@SpringBootApplication
public class Application {

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }

}

我尝试在本地复制您的设置，并且一切正常。

正如问题注释中所问的那样，我启用了调试输出以获取应用程序的自动配置报告，并且得到:

   ElasticsearchDataAutoConfiguration matched:
      - @ConditionalOnClass found required class 'org.springframework.data.elasticsearch.core.ElasticsearchTemplate' (OnClassCondition)

   ElasticsearchDataConfiguration.BaseConfiguration#elasticsearchConverter matched:

   ElasticsearchDataConfiguration.RestClientConfiguration matched:

   ElasticsearchDataConfiguration.RestClientConfiguration#elasticsearchTemplate matched:

ElasticsearchRestTemplate是由Spring Boot创建的，符合预期。请使用要求的信息更新您的问题。
