In this post I explain how we implemented the way we created the RSS feeds in a project and the challenges that we had during the set-up.
My colleague Jettro Coenradie explained in a previous post how you can create a feed using Rome and Spring 3, but didn’t elaborated on the Spring 3 part. I will explain how we used Spring 3 to create the feeds.
For a project I am doing there was a feature request to come up with an rss component for their new website. This seems pretty easy but the amount of possible feeds (100.000) and the potential for very high load made us think about a custom made solution based on ehcache, spring 3 and rome.
Some of the requirements for the solution have already been mentioned. The following list gives an overview of the things to consider.
Within this post I will discuss the different technical requirements for caching in these kind of solutions. I will also step through the creating of a feed using spring 3 and finally I present the demo application that can actually be used as a web application that exposes news content using a feed as well as a website.
