spring-boot - Elasticsearch和Java Spring Boot:java.lang.NoSuchMethodError:

Question

所以我试图让我的Spring Boot Web服务与Elasticsearch对话(我有另一个运行的Java应用程序)

我得到的错误是

DependencyException: Error creating bean with name 'searchController': Unsatisfied dependency expressed through field 'searchService'; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'searchService': Unsatisfied dependency expressed through field 'searchRepository'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'searchRepository': Invocation of init method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.data.elasticsearch.repository.support.SimpleElasticsearchRepository]: Constructor threw exception; nested exception is java.lang.NoSuchMethodError: org.elasticsearch.action.admin.indices.mapping.put.PutMappingRequestBuilder.execute()Lorg/elasticsearch/action/ListenableActionFuture; 2018-10-27 22:18:49.139 INFO 1925 --- [ main] o.apache.catalina.core.StandardService : Stopping service [Tomcat]

我的依赖(Gradle)是

compile group: 'org.elasticsearch.plugin', name: 'transport-netty4-client', version: '6.4.2'
    compile group: 'org.elasticsearch.client', name: 'transport', version: '6.4.2'
    compile 'org.elasticsearch:elasticsearch:6.4.2'
    compile('org.springframework.boot:spring-boot-starter-data-elasticsearch')

我的模特

@org.springframework.data.elasticsearch.annotations.Document(indexName = "burf", type = "pages")
data class Result(@Id val handle: String,
                  val url: String,
                  val title: String,
                  val body: String,
                  val meta_description: String?) {

}

设定档

@Configuration
@EnableElasticsearchRepositories(basePackages = arrayOf("com.burfdevelopment.skynet.repository\n"))
@ComponentScan(basePackages = arrayOf("com.burfdevelopment.skynet.service"))
class Config {

    @Value("\${elasticsearch.home:/usr/local/Cellar/elasticsearch}")
    private val elasticsearchHome: String? = null

    @Value("\${elasticsearch.cluster.name:skynet}")
    private val clusterName: String? = null

    @Bean
    fun client(): Client {
        val settings = Settings.builder()
                .put("cluster.name", clusterName).build()

        return PreBuiltTransportClient(settings).addTransportAddress(TransportAddress(InetAddress.getByName("192.168.0.100"), 9300))
    }

    @Bean
    fun elasticsearchTemplate(): ElasticsearchOperations {
        return ElasticsearchTemplate(client())
    }
}

资料库

interface SearchRepository : ElasticsearchRepository<Result, String>  {

    fun findByTitle(name: String, pageable: Pageable): Page<Result>
}

有人知道怎么了吗？

您使用的Spring Boot版本使用与Elasticsearch 6.4不兼容的Spring Data Elasticsearch版本。

为了确保使用兼容版本，请从Elasticsearch依赖项中删除该版本，并允许Spring Boot的依赖项管理来控制该版本。
