1、查找方面的区别
在增删改方面6.x和7.x是一样的在查找方面分为普通查找和有高亮的查找6.x和7.x有区别。
在7.x的es中 org.springframework.data.elasticsearch.core.SearchResultMapper没有这个类了 org.springframework.data.elasticsearch.core.ElasticsearchTemplate 已废弃 org.springframework.data.elasticsearch.repository.ElasticsearchRepositoryT,
ID.search(org.springframework.data.elasticsearch.core.query.Query) 已废弃
于是在普通查找和带高亮的查找方面es6.x和7.x不一样。
2、配置文件的区别
es6.x application.properties
# 旧版本以spring.data.elasticsearch.开头;访问地址配置不用声明访问协议,监听es的tcp端口
# 7.x已经弃用了
spring.data.elasticsearch.cluster-namemy-application
spring.data.elasticsearch.cluster-nodes127.0.0.1:9300es7.x application.properties
# 新版本以spring.elasticsearch.rest.开头;访问地址配置需要声明访问协议,直接监听es访问端口
spring.elasticsearch.rest.urishttp://localhost:92003、Document注解的type属性
es6.x 有type “_doc”
Document(indexName discusspost, type _doc, shards 6, replicas 3)
public class DiscussPost {}es7.x 无type “_doc”
Document(indexName discusspost, shards 6, replicas 3)
public class DiscussPost {}4、Elasticsearch Clients的区别
下方内容来自官方文档
https://docs.spring.io/spring-data/elasticsearch/docs/4.0.1.RELEASE/reference/html/#reference
ES6.xTransport Client
Configuration
public class TransportClientConfig extends ElasticsearchConfigurationSupport {Beanpublic Client elasticsearchClient() throws UnknownHostException {Settings settings Settings.builder().put(cluster.name, elasticsearch).build(); TransportClient client new PreBuiltTransportClient(settings);client.addTransportAddress(new TransportAddress(InetAddress.getByName(127.0.0.1), 9300)); return client;}Bean(name { elasticsearchOperations, elasticsearchTemplate })public ElasticsearchTemplate elasticsearchTemplate() throws UnknownHostException {return new ElasticsearchTemplate(elasticsearchClient());}
}ES7.xHigh Level REST Client
Configuration
public class RestClientConfig extends AbstractElasticsearchConfiguration {OverrideBeanpublic RestHighLevelClient elasticsearchClient() {final ClientConfiguration clientConfiguration ClientConfiguration.builder() .connectedTo(localhost:9200).build();return RestClients.create(clientConfiguration).rest(); }
}
