我要使用Spring Data Elasticsearch将Spring Boot 1.5.1支持添加到现有的Spring Data Neo4j 4.2.0.RELEASE应用中。
我在我的pom.xml中添加了以下Maven依赖项：
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-elasticsearch</artifactId>
</dependency>
现在我的应用程序在启动期间失败，但有以下异常：
Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'elasticsearchClient' defined in class path resource [org/springframework/boot/autoconfigure/data/elasticsearch/ElasticsearchAutoConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.elasticsearch.client.Client]: Factory method 'elasticsearchClient' threw exception; nested exception is java.lang.NoSuchFieldError: LUCENE_5_5_2

如何使用Spring Boot 1.5.1和Spring Data Neo4j 4.2.0.RELEASE正确配置Spring Data Elasticsearch 2.1.0.RELEASE？
答案 0 :(得分：2)
弹性搜索和Neo4j所需的Lucene版本是不同的。如果您使用neo4j-ogm-embedded-driver并且指定要使用的neo4j版本，则Spring Data Neo4j将仅使用Lucene库。在你的pom中你指定了所有三个驱动程序：bolt，http和embedded。
首先确定您真正需要的驱动程序。仅指定该驱动程序。如果使用嵌入式驱动程序，则需要添加另一个依赖项以添加要使用的Neo4j版本。当您在pom中包含此依赖项时，您必须排除lucene（或者告诉spring data elasticsearch排除lucene）。
您还必须意识到，如果您使用后一种选项，则可能在相关库中存在不兼容性。理想情况下，您将需要使用为Lucene使用相同主要和次要semver的Spring Data项目版本。
