Overview of this book

Get up to speed with Groovy, a language for the Java Virtual Machine (JVM) that integrates features of both object-oriented and functional programming. This book will show you the powerful features of Groovy 2 applied to real-world scenarios and how the dynamic nature of the language makes it very simple to tackle problems that would otherwise require hours or days of research and implementation. Groovy 2 Cookbook contains a vast number of recipes covering many facets of today's programming landscape. From language-specific topics such as closures and metaprogramming, to more advanced applications of Groovy flexibility such as DSL and testing techniques, this book gives you quick solutions to everyday problems. The recipes in this book start from the basics of installing Groovy and running your first scripts and continue with progressively more advanced examples that will help you to take advantage of the language's amazing features. Packed with hundreds of tried-and-true Groovy recipes, Groovy 2 Cookbook includes code segments covering many specialized APIs to work with files and collections, manipulate XML, work with REST services and JSON, create asynchronous tasks, and more. But Groovy does more than just ease traditional Java development: it brings modern programming features to the Java platform like closures, duck-typing, and metaprogramming. In this new book, you'll find code examples that you can use in your projects right away along with a discussion about how and why the solution works. Focusing on what's useful and tricky, Groovy 2 Cookbook offers a wealth of useful code for all Java and Groovy programmers, not just advanced practitioners.

Using Groovy to access MongoDB


MongoDB (http://www.mongodb.org) is a document-oriented database written in C++ with RDBMS-like features such as indexing and replication. It is developed and supported by 10gen.

MongoDB is very popular mainly for its simplicity: documents are created as JSON-like records (key/value pairs with a rich data type model) and the interface is simple enough to be used directly from JavaScript. It has been designed for scalability in mind. Its document-oriented data model allows it to automatically split up data across multiple servers, letting developers focus on application logic instead of scaling up the data store.

Other very useful features of MongoDB are built-in support for Map/Reduce-style aggregation and geospatial indexes.

This recipe will show you how to execute CRUD-like operations on a MongoDB instance and how to search for data.

Getting ready

MongoDB installation is quite simple, especially if you are on Linux or OS X, where you can use a package manager...
