问题描述
我想在spring数据mongodb中执行以下本机查询:
I want to execute the below native query in spring data mongodb :
db.runCommand({aggregate:"mycollection", pipeline :[{$match : {$and :
[{"orderDate" : {$gte : ISODate("2016-07-25T10:33:04.196Z")}},
{"orderDate" : {$lte :ISODate("2018-07-25T10:33:04.196Z")
}}
]}},
{ "$project" : { "orderType" : 1 ,"count" : 1 ,
"month" : { "$month" : [ "$orderDate"]}}},
{ "$group" : { "_id" : { "month" : "$month" , "orderType" : "$orderType"} ,
"count" : { "$sum" : 1} }}],
cursor:{batchSize:1000}})
我尝试使用mongoTemplate.executeCommand执行一个json字符串,请帮助...

推荐答案
您可以使用mongoTemplate.executeCommand(DBObject dbObject)
变体.
只需将日期更改为Json解析器支持的扩展json并构建命令.
Just change the date to extended json which is supported by Json parser and build the command.
类似
long date1 = Instant.parse("2016-07-25T10:33:04.196Z").toEpochMilli();
long date2 = Instant.parse("2018-07-25T10:33:04.196Z").toEpochMilli();
DBObject dbObject = new BasicDBObject(
"aggregate", "mycollection").append(
"pipeline", JSON.parse("[\n" +
" {\n" +
" \"$match\": {\n" +
" \"$and\": [\n" +
" {\n" +
" \"orderDate\": {\n" +
" \"$gte\": \""+ date1 +"\"\n" +
" }\n" +
" },\n" +
" {\n" +
" \"orderDate\": {\n" +
" \"$gte\": \""+ date2 +"\"\n" +
" }\n" +
" }\n" +
" ]\n" +
" }\n" +
" },\n" +
" {\n" +
" \"$project\": {\n" +
" \"orderType\": 1,\n" +
" \"count\": 1,\n" +
" \"month\": {\n" +
" \"$month\": [\n" +
" \"$orderDate\"\n" +
" ]\n" +
" }\n" +
" }\n" +
" },\n" +
" {\n" +
" \"$group\": {\n" +
" \"_id\": {\n" +
" \"month\": \"$month\",\n" +
" \"orderType\": \"$orderType\"\n" +
" },\n" +
" \"count\": {\n" +
" \"$sum\": 1\n" +
" }\n" +
" }\n" +
" }\n" +
"]")).append(
"cursor", new BasicDBObject("batchSize", 1000)
);
mongoTemplate.executeCommand(dbObject)
