springboot集成ElasticSearch遇到的一个小问题

Exception in thread "main" java.lang.NoSuchMethodError: org.elasticsearch.client.Request.addParameters(Ljava/util/Map;)V
    at org.elasticsearch.client.IndicesRequestConverters.getIndex(IndicesRequestConverters.java:489)
    at org.elasticsearch.client.RestHighLevelClient.internalPerformRequest(RestHighLevelClient.java:1607)

这个异常是es的client执行时报的，猜测是springboot默认了集成了某个版本的es导致的，所以我们需要在pom.xml里显式的声明我们es的版本：

    7.8.0
