springboot package version abnormal project dependencies es

 

 

 

 Add dependency in the pom.xml project

<dependency>
    <groupId>org.elasticsearch.client</groupId>
    <artifactId>elasticsearch-rest-high-level-client</artifactId>
    <version>7.6.1</version>
</dependency>

<dependency>
    <groupId>org.elasticsearch</groupId>
    <artifactId>elasticsearch</artifactId>
    <version>7.6.1</version>
</dependency>

 

 Down version 6.4.3 will always find items, and will refer to this version and then start the project, the method will not find the abnormal

Point into RequestConverters references found in version 7.6.1,

Request references and version is 6.4.3. Obviously version of the problem. It would be surprising, and I quote the 7.6.1 version, but rest-client package is 6.4.3.

 

 

The reason is because I use the springboot version 2.1.6. This version of springboot default referral is es version 6.4.3. So we have to specify the version of es in pom.xml explicitly

 <properties>
        <elasticsearch.version>7.6.1</elasticsearch.version>
    </properties>
