我正在尝试做this sample tutorial,以便熟悉elasticsearch.但是运行项目会在intellij中出现这个错误：

我搜索过,据说春季启动和elasticsearch版本之间可能存在冲突.但是在该教程的pom文件中没有指定弹性搜索版本：
是版本冲突的问题,我该如何解决？
最佳答案
看看我的Github repository.它适用于Elasticsearch版本2.4.6的实例.
不幸的是,Spring Boot Starter Data Elasticsearch不支持Elasticsearch 5.x版,他们正在研究它,但您可以使用我的存储库只是改变模型属性并使用您自己的方法更新存储库.
您的错误是因为您正在使用Elasticsearch 5.x的实例,并且您需要2.x版本.
