Elasticsearch 5.x Repository Java Spring Boot

问题:

I want to use the elasticsearchrepository with Java Spring Boot:

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

It is not a RELEASE version, but should work for elasticsearch 5.4.0. I'm using ELK stack 5.x.

I have the following pom.xml dependencies:

<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>     <artifactId>transport</artifactId>     <version>5.4.0</version> </dependency> <dependency>     <groupId>org.elasticsearch.client</groupId>     <artifactId>x-pack-transport</artifactId>     <version>5.4.0</version> </dependency> <dependency>     <groupId>org.springframework.data</groupId>     <artifactId>spring-data-elasticsearch</artifactId>     <version>3.0.0.BUILD-SNAPSHOT</version> </dependency> 

The following post repository:

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

Receiving the following error:

I cannot find why this error shows up. Who has experience with this?

回答1:

As I can see in the logs you are trying to use Spring Boot 1.X with the 3.X spring-data-elasticsearch (SDE).

I think that it won't work that way. SDE 3.X has dependency to spring-data-commons 2.X which as I know will be released with the Spring 5.X.

So in this case you have to use Spring Boot 2.X (2.0.0 M2 or last snapshot) which has dependency to Spring 5.X and uses the SDE 3.X (but to be honest I am not 100% sure is it working right now with latest snapshot of Spring Boot because SDE 3.X is still under development- I've tried SDE 3.X but with pure Spring own auto-configuration - not with boot).

You have to be also aware that Elasticsearch 5.X doesn't support embedded node out-of-the-box and within autoconfiguration for Spring Boot there is no embedded node now - only transport client.

回答2:

1. If you write it this way:

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

Change it into:

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

2.This dependency included elasticsearch 5.6.10 and elasticsearch.client:transport:5.6.10 already, Consider removing duplication

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

3. make sure the version of elasticsearch have keep consistent with your connections

4.Try

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