繼續(xù)報(bào)錯(cuò)：java.lang.NoClassDefFoundError: org/elasticsearch/plugins/NetworkPlugin

Caused by: java.lang.ClassNotFoundException: org.elasticsearch.plugins.NetworkPlugin

按照網(wǎng)上的解決方案，在pom.xml指定ElasticSearch的版本號(hào)

<dependency>
     <groupId>org.elasticsearch</groupId>
     <artifactId>elasticsearch</artifactId>
     <version>5.0.1</version>
</dependency>
<dependency>
       <groupId>org.elasticsearch.client</groupId>
       <artifactId>transport</artifactId>
       <version>5.0.1</version>
</dependency>

找到一個(gè)貌似比較靠譜的答案，spring boot 1.x不支持elasticsearch5.x

As I can see in the logs you are trying to use Spring Boot 1.X with the 3.X spring-data-elasticsearch (SDE).
I think that it won’t work that way. SDE 3.X has dependency to spring-data-commons 2.X which as I know will be released with the Spring 5.X.
So in this case you have to use Spring Boot 2.X (2.0.0 M2 or last snapshot) which has dependency to Spring 5.X and uses the SDE 3.X (but to be honest I am not 100% sure is it working right now with latest snapshot of Spring Boot because SDE 3.X is still under development- I’ve tried SDE 3.X but with pure Spring own auto-configuration – not with boot).
