我使用的是Elasticsearch7.2.0,因爲官網上推薦使用elasticsearch-rest-high-level-client端集成在springboot因此嘗試爬坑。html
首先直接引入官網的配置文件java
<dependency> <groupId>org.elasticsearch.client</groupId> <artifactId>elasticsearch-rest-high-level-client</artifactId> <version>7.2.0</version> </dependency>
而後在運行時報錯:spring
... ... Caused by: java.lang.ClassNotFoundException: org.elasticsearch.common.xcontent.DeprecationHandler ... ...
百度了一下說jar裏的Elasticsearch版本有錯,要移除了再從新引入,因此把配置文件改爲下面的樣子springboot
<dependency> <groupId>org.elasticsearch.client</groupId> <artifactId>elasticsearch-rest-high-level-client</artifactId> <version>7.2.0</version> <exclusions> <exclusion> <groupId>org.elasticsearch</groupId> <artifactId>elasticsearch</artifactId> </exclusion> </exclusions> </dependency> <!-- 正確版本 --> <dependency> <groupId>org.elasticsearch</groupId> <artifactId>elasticsearch</artifactId> <version>7.2.0</version> </dependency>
而後再次啓動,Elasticsearch正常運行,可是發現spring的rest服務運行不正常,配置的Filter沒有正常運行,且不報錯。網上找了好久也沒有找到有相似錯誤的問題,後來反覆查看官網,他說elasticsearch-rest-high-level-client是基於elasticsearch-rest-client的,我就猜這個基於會不會是依賴的意思呢?bash
因而把配置改爲了這樣:elasticsearch
<dependency> <groupId>org.elasticsearch.client</groupId> <artifactId>elasticsearch-rest-high-level-client</artifactId> <version>7.2.0</version> </dependency> <dependency> <groupId>org.elasticsearch.client</groupId> <artifactId>elasticsearch-rest-client</artifactId> <version>7.2.0</version> </dependency> <dependency> <groupId>org.elasticsearch</groupId> <artifactId>elasticsearch</artifactId> <version>7.2.0</version> </dependency>
而後再次啓動,Elasticsearch正常運行,REST服務也正常,個人老天鵝,終於能夠了。rest
後來我找到了這篇文章Elasticsearch High Level REST Client,具體配置能夠參考下code
