029 elasticsearch文档管理(ElasticsearchRepository、ElasticsearchRestTemplate)

文档的管理
ElasticSearchRepository接口
使用方法：
创建一个接口，继承于ElasticSearchRepository，指定使用的Entity类及对应主键数据类型
Springboot自动扫描接口并创建代理对象

1. 新增、更新数据
   使用repository的save方法实现
2. 删除数据
   deleteById
   deleteAll
3. 查询数据
   可以使用repository自带的查询方法
   findById
   findAll
   可以自定义查询方法
   findBy{Title}And{content}(String title, String content);
   按照命名规则定义方法，就可以实现相应的查询
