java - 使用 Spring Boot 2.0.3 启动 ElasticSearch 6.4.3 - 创建 bean 时出错

Question

我几乎尝试了一切，我发现对于每个次要版本的更改，都必须尊重复杂的依赖关系矩阵，我想我已经快到了。但 Spring 无法启动并出现错误: Error create bean with name 'articleRepository'此时不应创建它，因为我只是尝试启动应用程序，而不是实例化任何内容。

是否有任何分步、版本指南来使用 SpringBoot 启动 ElasticSearch？

你能帮我找出问题所在吗？

Answer 1

Spring Data Lovelace 版本系列支持 Elasticsearch 6.4。 Spring Boot 2.1 默认使用它。

最简单的选择是升级到 Spring Boot 2.1 并使用其依赖管理提供的版本。
