我有以下代码可以在 groovy 中插入文档，但我在 grails 应用程序中不断收到此错误

   def zipcode = getDocumentCollection()
   zipcode.insert(["city": "ACMAR", "loc": [-86.51557F, 33.584132F], "pop": 6055, "state": "AL", "_id": "35004"])

没有方法签名：com.mongodb.DBApiLayer$MyCollection.insert() 适用于参数类型：(java.util.LinkedHashMap) 值：[[city:ACMAR, loc:[-86.51557, 33.584133], ...] ] 可能的解决方案：insert([Lcom.mongodb.DBObject;), insert(java.util.List), insert([Lcom.mongodb.DBObject;, com.mongodb.WriteConcern), insert(com.mongodb.DBObject, com .mongodb.WriteConcern），插入（com.mongodb.WriteConcern，[Lcom.mongodb.DBObject;），插入（java.util.List，com.mongodb.WriteConcern）

此代码取自 gmongo 的示例。任何想法为什么我会出错？

更新
在尝试@dmahapatro 的方法后，我在 Grails 应用程序中收到以下错误：

当您使用时，insert您需要提供键值对作为命名参数（我认为您也可以使用映射，但它会不那么冗长）。

zipcode.insert(city: "ACMAR", loc: [-86.51557F, 33.584132F], pop: 6055, state: "AL", _id: "35004")

如果要使用 aHashMap然后使用左移运算符将文档插入到集合中。

zipcode << ["city": "ACMAR", "loc": [-86.51557F, 33.584132F], "pop": 6055, "state": "AL", "_id": "35004"]

如果我使用聚合，我会采用第二种方法。

样本

在测试时，这对我来说是完美的。

@Grab(group='com.gmongo', module='gmongo', version='1.0')
import com.gmongo.GMongo

def mongo = new GMongo("127.0.0.1", 27017)
def db = mongo.getDB("gmongo")
//Instead of doing below I can also use db.zipcodes.insert(blah: blah)
def zipCode = db.getCollection("zipcodes")
zipCode.insert(city: "ACMAR", loc: [-86.51557F, 33.584132F], pop: 6055, state: "AL", _id: "35004")
zipCode << [city: "DUMMY", loc: [-86.51587F, 33.584172F], pop: 6056, state: "AL", _id: "35005"]

assert db.zipcodes.findOne(city: "DUMMY").city == 'DUMMY'
assert db.zipcodes.findOne(city: "ACMAR").city == 'ACMAR'
