Hello,

I am pleased to announce the Wellington Java User Group meeting for June 2016.

Querydsl - Unified Queries for Java

Wednesday, June 8: 5:00 for 5:15 - 6:30pm

What is Querydsl?

Querydsl is a Java framework which allows for generation of type-safe queries in a syntax very similar to SQL. The framework provides a number of modules for supporting a variety of backends, including JPA, SQL, Lucene and even Java Collections. This session will focus on the Querydsl framework and show a number of examples of each of the modules.

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

- code completion in IDE

- almost no syntactically invalid queries allowed

- domain types and properties can be referenced safely

- adopts better to refactoring changes in domain types

Speaker: Marvin Froeder

Marvin has 11 years’ experience in IT, mainly as a Java Engineer. Just arrived from Brazil an year ago. During his time in Brazil, he worked for several startups, most notably at ContaAzul (Online booking) and Sonatype (the company behind Maven).
