java.lang.NoClassDefFoundError: org/elasticsearch/search/aggregations/metrics/max/MaxAggregationBuilder

Question

我正在将我的应用程序从 spring-boot 2.0 升级到 2.3，然后我发现这个关于弹性搜索的错误

当我在网上搜索时，我找到了this question，但我的情况有点不同，我没有在代码中的任何地方明确使用MaxAggregationBuilder，因此它可能隐藏在抽象的某个地方。

注意：我没有明确指定spring-data-elasticserch 的版本，我知道它应该是4.x，但我把它留给了spring boot parent，所以我不认为这是一个依赖问题，但我不知道。

Answer 1

Spring Data Elasticsearch 本身不会在其代码中构建任何聚合，因此在创建 NativeSearchQuery 时必须在其他地方引用它 - 这是在 Spring Data Elasticsearch 中构建聚合请求的唯一方法。您是否包含其他可能会创建一些请求的库？
顺便说一句，请求的类在包org.elasticsearch.search.aggregations.metrics中。

Spring Boot 2.0 使用 Spring Data Elasticsearch 3.0.x 和 Elasticsearch 5.5.0，而 Spring Boot 2.3 使用 Spring Data Elasticsearch 4.0.x 和 Elasticsearch 7.6。我想这个包在 5.5 和 7.6 期间在 Elasticsearch 中发生了变化。
