springboot 集成es是出现这个错误

经过排查发现是因为两者的版本不兼容

springboot版本

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
    <version>2.1.2.RELEASE</version>
</dependency>

RestHighLevelClient版本

<dependency>
    <groupId>org.elasticsearch.client</groupId>
    <artifact5.6.0</version>
</dependency>

报错内容:

Description:

An attempt was made to call the method org.elasticsearch.client.RestHighLevelClient.<init>(Lorg/elasticsearch/client/RestClientBuilder;)V but it does not exist. Its class, org.elasticsearch.client.RestHighLevelClient, is available from the following locations:

    jar:file:/D:/repository/owner/org/elasticsearch/client/elasticsearch-rest-high-level-client/5.6.0/elasticsearch-rest-high-level-client-5.6.0.jar!/org/elasticsearch/client/RestHighLevelClient.class

It was loaded from the following location:

    file:/D:/repository/owner/org/elasticsearch/client/elasticsearch-rest-high-level-client/5.6.0/elasticsearch-rest-high-level-client-5.6.0.jar

Action:

Correct the classpath of your application so that it contains a single, compatible version of org.elasticsearch.client.RestHighLevelClient

后面把springboot的版本号改成了

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
    <version>2.0.1.RELEASE</version>
</dependency>

后面启动就生效了，所以出现以上的提示很大可能是版本兼容问题
