Elasticsearch 5.x仓库Java Spring Boot

Question

我想使用带有Java的弹性搜索库：

• https://github.com/spring-projects/spring-data-elasticsearch

它不是一个发行版，但应该适用于ElasticSearch5.4.0。我用的是麋鹿堆栈5.x。

我有以下pom.xml依赖项：

<repositories>
<repository>
    <id>elasticsearch-releases</id>
    <url>https://artifacts.elastic.co/maven</url>
    <releases>
        <enabled>true</enabled>
    </releases>
    <snapshots>
        <enabled>false</enabled>
    </snapshots>
</repository>

​

<dependency>
    <groupId>org.elasticsearch</groupId>
    <artifactId>elasticsearch</artifactId>
    <version>5.4.0</version>
</dependency>
<dependency>
    <groupId>org.elasticsearch.client</groupId>

<dependency>
    <groupId>org.springframework.data</groupId>
    <artifactId>spring-data-elasticsearch</artifactId>
    <version>3.0.0.BUILD-SNAPSHOT</version>
</dependency>

以下员额储存库：

@Repository
public interface IElasticPostRepository extends ElasticsearchRepository<Post, String> {
}

接收以下错误：

我找不到为什么会出现这个错误。谁有这方面的经验？

Answer 1

正如我在日志中看到的，您正在尝试在3.X Spring elasticsearch (SDE)中使用SpringBoot1.X。

我觉得这样行不通。SDE3.x依赖于Spring Commons2.x，据我所知，它将与Spring5.x一起发布。

因此，在本例中，您必须使用SpringBoot2.x (2.0.0 M2或最后一次快照)，它依赖于Spring5.x，并使用SDE3.x(但老实说，我还不能100%确定它现在是否适用于Spring的最新快照，因为SDE3.x还在开发中--我已经尝试了SDE3.x，但使用的是纯Spring自己的自动配置，而不是引导)。

您还必须注意，Elasticsearch 5.X不支持嵌入式节点开箱即用，而且在Spring的自动配置中，现在没有嵌入式节点- 只有传输客户端。

Answer 2

1. 如果你这样写：

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-redis</artifactId>
</dependency>

改为：

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-redis</artifactId>
    <version>x.x.x.RELEASE</version>
</dependency>

2.这种依赖性包括elasticsearch 5.6.10和弹性搜索。客户端:transport5.6.10已在考虑删除重复。

<dependency>
    <groupId>org.springframework.data</groupId>
    <artifactId>spring-data-elasticsearch</artifactId>
    <version>3.0.0.BUILD-SNAPSHOT</version>
</dependency>

1. 确保elasticsearch的版本与您的连接保持一致

4.Try

    <dependency>
        <groupId>org.elasticsearch.client</groupId>
        <artifactId>transport</artifactId>
        <version>5.6.10</version>
    </dependency>
