Hi Springer,
I am learning Spring Mongo, and I am using Spring 3.2.2, Spring Data Mongo 1.2.1.
https://github.com/hantsy/spring-san...ets/data-mongo
The source codes under https://github.com/hantsy/spring-sanbox also include other data store. such JPA. I used Data JPA and Query DSL, it worked well.
But switched to Mongo and QueryDSL, the @DBRef can not be queried.
The test codes:
Query by QSignup.signup.conferenceXXXX alway return empty list.
Confernce and Signup class.
The QueryDSL apt maven plugin is configured correctly and the QConferecne and QSignup are generated as expected.
