[spring-projects-issues]

deepesh-verma opened DATACMNS-1808 and commented

The current implementation of the QuerydslPredicateArgumentResolver, which in turn uses the QuerydslPredicateBuilder.getPredicate() method, supports Precdicate building by parsing request parameters as below - 

?name=deepesh&age=28&language=hindi,english

Can this be enhanced to support the below request parameters, and allow user the pass the com.querydsl.core.types.Ops values as below - 

?name=deepesh,EQ&age=25,GT&language=[hindi,english],IN

I have a draft PR open with the first draft of changes. I have made sure that all the existing test cases are passing. Will update it with more test cases backing my changes and do a round of cleanup, before I make this ready for review.

Oliver Drotbohm, It will be great if you can review this and let me know if this seems like something which might be a fine addition, so that I can work further on it.
