去年寫的乙個小工具類,整理了一下分享出來
源設計**於csdn某篇博文,這個工具類是在那位博主基礎上新增了一些功能,找了很久找不到那篇博文位址了,十分抱歉,在此宣告一下。如果有找到的朋友可以跟我說,我好把鏈結加上。
這是乙個簡陋的es工具類
elasticsearch 6.0.0
test=, "num": , "begin_date": } }
string index =
"test"
;string type =
"testtype"
;elasticsearchservice elasticsearchservice =
newelasticsearchservice()
;elasticsearchservice.
createindex
(index, type)
;
一共有四種新增資料的方式
string index =
"test"
;string type =
"testtype"
;elasticsearchservice elasticsearchservice =
newelasticsearchservice()
;map
data =
newhashmap
();map
param =
newhashmap
();param.
put(
"name"
,"張三");
param.
put(
"num",1
);param.
put(
"begin_date"
,"2019-02-11 10:10:10");
mapparam1 =
newhashmap
();param1.
put(
"name"
,"張三四");
param1.
put(
"num",2
);param1.
put(
"begin_date"
,"2019-02-10 06:06:06");
data.
put(digestutils.
md5hex
(json.
tojsonstring
(param)
), param)
;data.
put(digestutils.
md5hex
(json.
tojsonstring
(param1)
), param1)
;elasticsearchservice.
bulkinsertdataprocesser
(index, type, data)
;
termesquerybuilderconstructor esbc =
newesquerybuilderconstructor()
;esquerybuilders esb =
newesquerybuilders()
;esb.
term
("name"
,"張三");
esbc.
must
(esb)
;map
data = ess.
search
(index, type, esbc,
newstring
);data.
foreach
((key,value)
->
);
esquerybuilderconstructor 分為must,should,mustnot
must 必須匹配 and
should 可匹配 or
mustnot 必不匹配 非 and
match
esquerybuilderconstructor esbc =
newesquerybuilderconstructor()
;esquerybuilders esb =
newesquerybuilders()
;esb.
match
("name"
,"張三");
esbc.
must
(esb)
;map
data = ess.
search
(index, type, esbc,
newstring
);data.
foreach
((key,value)
->
);
後面跟es提供的型別一樣,請參閱es查詢方式,這裡就不一一舉例了
esquerybuilderconstructor esbc =
newesquerybuilderconstructor()
;esquerybuilders esb =
newesquerybuilders()
;esgroupby esgb =
newesgroupby
("num");
esgb.
desc(2
);esbc.
setesgroupby
(esgb)
;
desc,esc中1:by_count
2:by_key
分組日期需要增加一段
esgb.
setsearchway
(searchway, format, interval)
;
searchway 預設為1
1:search_term
,2:search_date
esquerybuilderconstructor esbc =
newesquerybuilderconstructor()
;esquerybuilders esb =
newesquerybuilders()
;esgroupby esgb =
newesgroupby
("num");
esgb.
min(
"num"
,"min");
esbc.
setesgroupby
(esgb)
;
elasticsearchservice.
getsearchdatabyscrolls
(indexfrom, indexto, type)
;
indexfrom: 源索引
indexto: 目標索引
type: 共用的型別名必須相同
elasticsearchservice.
deleteindex
(index)
;
elasticsearchservice.
delbyquery
(index,map,notmap)
;
index 索引名
map 暫時只支援 must->term
notmap 同理 mustnot->term
將查詢到的資料刪除
這裡是git位址
