delete all records in mongoDB Spring application using CURL

I'm Working with one of Spring's tutorials on integrating Spring with Mongo DB. http://ift.tt/1nMSrHF

I simply want to be able to delete multiple records using CURL.

something like

curl -X DELETE http://localhost:8080/people/

The tutorial shows how to delete a specific record but not multiple records. Fairly new with working with CURL as well..Pretty sure I'm missing something simple, thanks.
