    "_class" : "ead.cs.domain.ShipSchedule",
    "ship" : {
        "_id" : ObjectId("55d6e4ed44ae8b2f121c2e55"),
        "referenceId" : "1",
        "name" : "Dasun Ship",
        "description" : "Desv"
    },
    "departureDate" : ISODate("2015-08-20T18:30:00Z"),
    "arrivalDate" : ISODate("2015-08-29T18:30:00Z"),

    "distance" : 100,

如何通过提供船舶的objectId

获取此文档

我在下面尝试但没有工作

db.shipSchedules.findOne(ObjectId("55d6e4ed44ae8b2f121c2e55")).pretty();


db.shipSchedules.findOne("ship":ObjectId("55d6e4ed44ae8b2f121c2e55")).pretty();

我怎样才能完成这项工作？

Answer 1

db.shipSchedules.findOne({ "ship._id":ObjectId("55d6e4ed44ae8b2f121c2e55")})
