I am working on spring data mongodb project and i have a complex object that not able to map using metadata mapping because it has composite key. I wrote a custom converter and trying to use mongoTemplate.find() but its not triggering the custom converter mapping.
Configuration:
converters:
Service class:
Using spring data 1.1.0 version,
If anybody find what am doing wrong here, please let me know
thank you in advance :)
