SpringBoot 集成 ElasticSearch 报错

Error creating bean with name ‘elasticsearchOperations’ defined in class path resource [com/ruixin/esSpring/ElasticsearchConfig.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.data.elasticsearch.core.ElasticsearchOperations]: Factory method ‘elasticsearchOperations’ threw exception; nested exception is java.lang.NullPointerException

我这里用的 ElasticSearch 为本地 windows 下的，

问题解决：修改 springboot 默认ElasticSearch 版本

在 pom.xml 中添加这行配置，我的本地es版本就是 7.8.0
