            "OOPS", 
            "CORE JAVA", 
            "JDBC"

    {
        "skillID" : "2",
        "skillLists" : [

推荐答案

您可以尝试

db.collection.update(
  { "userID": "1", "userSkilldetailslists": { "$elemMatch": { "skillID": "1" }}},
  { "$push": { "userSkilldetailslists.$.skillLists": "SERVLETS" }}
)
