Development methodology is a framework that is used to structure, plan, and control the development of software systems. Agile and CMMI Waterfall methodologies are very alike and have enough differences to be named differently. Let’s consider the methodologies in detail.
Representational state transfer (REST) is a very popular architecture for distributed hypermedia. Lots of different web services expose their APIs in a RESTful manner. It is very convenient when a service of a choice provides a library for its API, but this is not always so. In this case you have to construct valid requests and parse responses by yourself. Assuming that you are familiar with REST itself, I will tell you how you can make your life easier with the help of Spring and Java annotations.
Hi, guys, today we’re gonna talk about the really interesting and tricky Grails task, implementation of the custom sorting.
It’s a pretty often appearing situation, when you need to sort the list of items, basing on the values that can only be calculated, and that are not persisted in the db.
I know what you might say, - "Hey, why don’t you just use transient properties for that?"
Unlike Java, which mixes primitive and reference types, Groovy handles everything in common manner — as objects, what makes it truly object-oriented. When a primitive type gets passed into the Groovy world, it is automatically “boxed” into its object equivalent, and vice versa. This allows Groovy to support some interesting concepts like methods on primitives, operator overloading and The Groovy Truth. Let’s look at them more closely.
Hudson is an excellent continuous integration tool and has become an indispensable assistant in software quality control for many organisations. As for this post I will describe how to couple Hudson and Grails to work in effective synergy.
Spring Security plugin is a fast and convenient solution for authorizing user access. Almost every Grails web application uses it. In this article I would like to provide a guide about how to apply this solution quickly, and show you some tips that should be really useful for beginners.
Groovy is an object oriented dynamic language for the JVM. Dynamically compiled to a bytecode and interoperable with most Java libraries, Groovy is a perfect candidate for writing lightweight scripts that still can benefit from the Java ecosystem. Also, it is really easy to learn since the good old Java syntax is usually valid in Groovy. There are, however, a few caveats that you should be aware of before start coding. This post shows some specific features, and also gives a few suggestions which will help to write a clear, groovy-style code.
At our company’s blog we have already considered many types of the Grails testing. But there are yet one testing type, on which we have to take a look at. In this article we will check out the overview of writing functional tests using Geb/Spock technologies.
Git is a version control system, that was designed by Linus Torvalds, first released in 2005. In opposite to CVS (concurrent version systems) systems, which in it’s basics have a file as a processing item, in the Git basics lays work with the set of changes, other words, patches. This article dedicated to that persons, that is already familiar with the version control systems, such as SVN, and wants to know more about alternative version control solutions and persons that wants to get a tutorials about quick migration to the Git.
