Querydsl - Typesafe queries for Java

Easy and safe to use, the right tool for Adaptive Domain Development.

Description

Querydsl (spell: query diesel) is a framework which enables the construction of statically typed SQL-like queries. Instead of writing queries as inline strings or externalizing them into XML files they can be constructed via a fluentDSL/API like Querydsl.

The benefits of using a fluent API in comparison to simple strings are

  • code completion in IDE (all properties, methods and operations can be expanded in your favorite Java IDE)
  • almost none syntactically invalid queries allowed (type-safe on all levels)
  • domain types and properties can be referenced safely (no Strings involved!)
  • adopts better to refactoring changes in domain types
  • incremental Query defintion is easier
