SpringBoot2.x项目模块整合之elasticSearch 6.x（geo使用等）

elasticsearch安装：https://blog.csdn.net/u012888052/article/details/79710429

ik分词安装：https://blog.csdn.net/u012888052/article/details/81941912

springboot整合：https://blog.csdn.net/chen_2890/article/details/83895646（这篇总结的很到位）

我这里主要将就geo的使用：

如果使用geo功能必须使用ElasticsearchTemplate，必须使用Mapping先去创建然后在添加数据，否则会出现geo类型错误

使用Repository基本查询：
