【问题描述】：
我正在将我们的一个应用程序从 spring-boot 版本 2.1.3.RELEASE 升级到 2.2.0.RELEASE，但我在使用 Elasticsearch 时遇到了一些问题。这是我得到的错误：
java.lang.IllegalStateException: Failed to load ApplicationContext
Caused by: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'customCdrElasticConfig': Unsatisfied dependency expressed through field 'elasticsearchTemplate'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'org.springframework.data.elasticsearch.core.ElasticsearchTemplate' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true), @org.springframework.beans.factory.annotation.Qualifier(value=elasticsearchTemplate)}

【问题讨论】：
-
我在 Spring Boot 项目的 POM 文件中检查了 here，并验证了
6.8.13是使用 Spring Boot2.2.x时 ElasticSearch 的正确版本。 -
"ElasticsearchTemplate" (org.springframework.data.elasticsearch.core.ElasticsearchTemplate) 是 Spring Data Elasticsearch 的一部分，我在您共享的 pom 中看不到这种依赖关系。
-
@Shailendra ：抱歉错过了之前在问题中添加的内容，它已经存在于 pom.xml 中。我使用的是 3.2.3.RELEASE 版本。
