@Encrypted Support in POJOs for Aggregation Pipeline #61

Open PradeepNooney4569 opened 9 months ago

PradeepNooney4569 commented 9 months ago

Hello , I'm using an aggregate pipeline in MongoDB and have a POJO class to represent the results. Projection involves a class with encrypted fields.

I tried using @Encrypted in the POJO class, expecting automatic decryption during aggregation, but its getting only Binary Data only.

If there's an existing solution or workaround, kindly provide guidance. Thanks!

Hi!

Thanks for the report. Some operations are not supported, since they do not go through the 'normal' spring-data save/load events.

This is one of those. There is no actual 'save' or 'load' event sent by spring-data-mongodb, however, there seems to be a way to register for conversion to cover this case too.

I'll need to take a deep dive into how to make use of the BeforeConvert/AfterConvert events in spring-data. And also add coverage for mongoTemplate.aggregate() in the test suite. If you feel like it, feel free to peek into this, or else I'll try check this out.
