ODATA4 filter to SQL where

I have created an odata service with postgrace database. I need to implement filter. For that I need to convert filter url params to jdbc where clause. Have anyone done this already?

Best Regards, Malaka Silva

Implementing ExpressionVisitor interface from Apache Olingo (based on the tag I assume you use this library) is your way to go.

I did an example app with Spring, Hibernate and Apache Olingo and used the mentioned interface for creating a HQL query. You can see the code here and here and build on top of this with JDBC. App main directory: https://github.com/sollersconsulting/confitura2017/tree/master/snapgram.
