问题
I have a JSON file (from Mongo University) with some JSON in it
However, when I run the import:
PS C:\Program Files\MongoDB\Server\3.0\bin> .\mongoimport.exe -d blog -c posts --drop posts.json
I get an error and nothing is imported:

What's going on?
I've tried it with 3.0 and 3.2.
回答1:
According to https://jira.mongodb.org/browse/TOOLS-939, there is a bug which is affecting some versions of mongoimport and mongorestore that causes your mongoimport command to fail.
To sort out this problem, you can use --batchSize option with argument as 1.
Use this reformed query:
mongoimport -d blog -c posts < posts.json --batchSize 1
Hope this will work.
回答2:
Try with -j or --numInsertionWorkers flag. Some version has some issues and ticket was created in past. https://jira.mongodb.org/plugins/servlet/mobile#issue/TOOLS-939
mongoimport -j 4 -d blog -c posts --drop posts.json
回答3:
Try the following format
mongoimport posts.json -d blog -c posts --drop --jsonArray
回答4:
To import json file to your currently working mongoDB batabase, please follow the steps given below.
- Go to your the link and then select the cluster that your currently working with.
- Click on COLLECTIONS and after that go to command line tools.
- You can see Data Import and Export Tools over there which provides the command to import your json file to your database.
- Replace the tags as instructed in the command.
If you get any error like:
Failed: cannot decode array into a D
Then add --jsonArray at last of the command. Example:
mongoimport --host <hostname> --ssl --username <username> --password <PASSWORD> --authenticationDatabase admin --db <DATABASE> --collection <COLLECTION> --file <FILENAME> --jsonArray
