RequestReturnUtil 接口调用工具类
Delate 192.168.2.29:9200/bp_view/1 //删除数据
POST 192.168.2.29:9200/bp_view/_delete_by_query?refresh&slices=5&pretty { "query": { "match_all": {} } } //清空数据
封装工具介绍
void getParmOfdeleteCataByID(List<String> list)
参数传入ids删除编目数据
void getParmOfdeleteCollectionByID(List<String> list)
参数传入ids删除典藏数据
void addCollection(String id ,String json)
参数传入id和典藏参数
void addCata(String id ,String json)
参数传入id和典藏参数
服务
Windows
启动时通过cmd直接在elasticsearch的bin目录下执行elasticsearch
这样直接启动的话集群名称会默认为elasticsearch，节点名称会随机生成。
停止就直接在cmd界面按Ctrl+C
其实我们也可以将elasticsearch设置为windows系统服务：
elasticsearch的bin目录下有一个elasticsearch-service.bat
进入bin目录下执行:
elasticsearch-service.bat install
1
然后在系统服务中可以看到Elasticsearch已成为系统服务。
elasticsearch-service.bat后面还可以执行这些命令
install: 安装Elasticsearch服务
remove: 删除已安装的Elasticsearch服务
start: 启动Elasticsearch服务
stop: 停止服务
