初步判定，应该是spring-boot-starter-data-elasticsearch与Elasticsearch 7.x版本不兼容造成的。

通过测试发现，将Elasticsearch降级到6.x版本，即可解决。

【2019-08-22】更新

最新版本

<dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-elasticsearch</artifactId>
        <version>2.1.7.RELEASE</version>
    </dependency>

由https://mvnrepository.com网页可知，spring-boot-starter-data-elasticsearch编译依赖于spring-boot-starter和 spring-data-elasticsearch，进一步知道spring-data-elasticsearch的最新版本时3.1.10

通过github网址：https://github.com/spring-projects/spring-data-elasticsearch  
可知当前最新发布版是3.1版本，对应Elasticsearch版本时6.2.2，尚不支持Elasticsearch 7.x版本
