Querydsl is a framework which enables the construction of type-safe SQL-like queries for multiple backends including JPA, MongoDB and SQL in Java.

Instead of writing queries as inline strings or externalizing them into XML files they are constructed via a fluent API.

How to build

Querydsl provides releases via public Maven repositories, but you can also build the sources yourself like this

$ mvn -DskipTests=true clean install

For more information visit the project homepage at

Vagrant/Puppet setup

For running tests, a Vagrant/Puppet setup is provided. It is based on Ubuntu 12.04 and comes with the following databases:

  • Oracle Express Edition 11g
  • PostgreSQL 9.1.10
  • MySQL 5.5.34
  • Cubrid 9.2

You will need to install VirtualBox, Puppet, Vagrant, the vagrant-vbguest plugin and librarian-puppet. You will also need to download the Oracle XE 11g installer file ( manually and place it in the devops directory.

To launch the virtual machine:

$ cd devops
$ librarian-puppet install
$ vagrant up

All of the databases' default ports are forwarded to the host machine. See the Vagrantfile for details.
