FreeGrid Java server helpers
============================

GridRequest  reads the grid's request (paging, sort, filters, advanced filter, grouping)
GridQuery    turns it into SQL: only the columns you allow, every value bound
GridRows     turns JDBC / MyBatis rows into JSON-friendly values (dates as text)
GridSave     reads { created, updated, deleted } from saveChanges()

Plain Java 8: Spring Boot, eGovFrame 3.x to 5.x, MyBatis or JdbcTemplate.
Copy the folder into your project and change the package name if you like.
