MongoDB中ObjectId()内容json文件导入

MongoDB中数据内容
{
    "_id" : ObjectId("5b863ce743bcde4d873ab48a"),
    "_class" : "com.mongodb.BasicDBObject",
    "traceId" : "2d801db9ae86e0869e0f8c3a1fdd1c8f",
    "signature" : "签名信息",
    "timestamp" : NumberLong(1535524071355)
}

想要使用json文件直接insert到mongodb中，ObjectId不符合json规范

定义成 如下json文件，即可

{
    "_id" :{ "$oid" : "5b863ce743bcde4d873ab48a"},
    "_class" : "com.mongodb.BasicDBObject",
    "traceId" : "2d801db9ae86e0869e0f8c3a1fdd1c8f",
    "signature" : "签名信息",
    "timestamp" : 1535524071355
}
