我可以通过传递索引名称,类型和ID来删除文档,如下所示:
DeleteRequest deleteRequest = new DeleteRequest(data.getIndexName(),data.getType(),data.getUniqueId()); DeleteResponse deleteResponse = client.delete(deleteRequest);
但是,当我试图通过仅提供索引名称来删除索引时,如下所示(根据此文档)
DeleteRequest deleteRequest = new DeleteRequest(allData.getIndexName()); DeleteResponse deleteResponse = client.delete(deleteRequest);
得到-
org.elasticsearch.action.ActionRequestValidationException: Validation Failed: 1: type is missing;2: id is missing;
我已经尝试过另一种这样的方式(参考)
DeleteIndexRequest request = new DeleteIndexRequest(allData.getIndexName()); AcknowledgedResponse deleteIndexResponse = client.indices().delete(request, RequestOptions.DEFAULT);
得到:
java.lang.NoSuchMethodError: at org.elasticsearch.client.IndicesClient.delete(IndicesClient.java:93) ~[elasticsearch-rest-high-level-client-6.5.4.jar:6.4.3]
我正在使用此依赖项:
<dependency> <groupId>org.elasticsearch.client</groupId> <artifactId>elasticsearch-rest-high-level-client</artifactId> <version>6.5.4</version> </dependency>

Spring-boot v2.1.2发行版为Elasticsearch版本定义了以下属性:
<elasticsearch.version>6.4.3</elasticsearch.version>
和以下依赖
<dependency> <groupId>org.elasticsearch</groupId> <artifactId>elasticsearch</artifactId> <version>${elasticsearch.version}</version> </dependency>
这就是在依赖树中这样做的原因
org.elasticsearch:elasticsearch:jar:6.4.3:compile
要强制负载Elasticsearch 6.5.4,请在pom中添加以下属性,该属性将覆盖spring-boot-dependencies pom中定义的属性。
<properties> <elasticsearch.version>6.5.4</elasticsearch.version> </properties> <dependencies> ... <dependency> <groupId>org.elasticsearch.client</groupId> <artifactId>elasticsearch-rest-high-level-client</artifactId> <version>${elasticsearch.version}</version> </dependency> ... </dependencies>
