Spring Data Mongo not reporting mongo unique constraint error

[riddler23]

Hi

I am new to using Spring Data with mongo. I configured mongo to have unique contraint on a collection so that the name element is unique.

The code works as expected, not allowing duplicates to be entered, but I get nothing back in the app - no exception or error.

How can I set this to occur?

Thanks for your help....

a little more clarification....if a user enter a name that is already in mongo I want to be notified some how so I can display the message to the user in the UI

At the risk of talking to myself, I found the answer to my own question. It's amazing what happens when one reads the instructions

I added this statement when creating my mongotemplate and I am good to go. Exceptions are now thrown and caught.

mongoTemplate.setWriteConcern(WriteConcern.SAFE);
