java - Java 中的 ElasticSearch 库无法找到 AggregationBuilders.sum 方法

Question

我试图在java中使用ElasticSearch的AggregationBuilders api来查找总和聚合。但是在使用使用此(AggregationBuilders.sum())方法的服务时，它给出以下错误:

java.lang.NoSuchMethodError:org.elasticsearch.search.aggregations.;

这是我的 pom.xml 文件

到目前为止，我已尝试清理 .m2 并再次运行干净安装，但仍然出现此错误。任何帮助将不胜感激:

PS:更改 pom 后，我可以停止安装 elasticsearch 6.5，但 6.4.3 仍在安装。我只想要 7.2 版本。知道如何找到导致其他版本安装的依赖项

es模块新增Pom

Answer 1

Spring Data Elasticsearch 3.2 不适用于 Elasticsearch 7； 3.2.0.GA使用Elasticsearch 6.8。

对 Easticsearch 7 的支持和适配位于当前的主分支中，稍后将成为版本 4
