This is perhaps the best solution in most cases that need to apply multiple contexts or share conditions. If you start to feel lost, you may want to review the "Build Your First Drupal 7 Web Site" collection where we cover these. This way the page will stop on only one context, yet that one context contains multiple contexts within it. PrerequisitesĪ basic familiarity with Drupal concepts and terminology will be useful. This will of course be useful for determining which techniques to use on your own projects, but because we will cover the most common techniques you will be likely to run into when working with existing Drupal projects, this collection will help you tremendously when working on a team. This collection is for anyone who wants to learn the most powerful tools and techniques for organizing and positioning content on a Drupal site.

How to import content into your site using the Feeds module.Working with advanced Views tools like relationships and argument-passing.How to use Display Suite for positioning content and building new view modes without code!.How to use the Panels modules to position content.How to configure content types and decide when to share fields and other configuration.How to set up administrative tools to speed up your building process.Some of the key points we'll be covering include: Follow the videos in the Setting Up a Web Environment With Drupal to get Drupal set up on your Windows, OSX (Mac) or Linux machine. Most importantly, we look at how all of these tools work together and how to decide which tools are best for which situation.īefore watching this series, you will need a fresh Drupal 7 installation. We uncover importing content into a Drupal site with the Feeds module, build and customize a slideshow with Views Slideshow and immerse ourselves in ways to spam-proof our site. Here we look deep into Views, Panels, Display Suite, and Context modules for laying out Drupal pages. There are errors displayed in the console related to exporting JMX endpoints, however, these are informational and don't appear to affect the start-up.Get ready for a dive into some of Drupal's most powerful tools for site builders.
This section provides an overview of security contexts. For unsupported features in multiple context mode, see Guidelines for Multiple Context Mode. A visualization via the /beans actuator endpoint shows this: Multiple contexts are similar to having multiple standalone devices. If the application is now started up, there would be a root context with two different child contexts, each exposing an endpoint via a different port. The application context returned by the SpringBootApplicationBuilder appears to be the final one in the chain, defined via ChildContext2 above. Given this setup, Spring Boot provides a fluid interface to load up the root context and the two child contexts: SpringApplicationBuilder appBuilder =ĬonfigurableApplicationContext applicationContext = n() The port to listen on is provided as properties, since the two contexts are expected to listen on different ports I have explicitly specified the property file to load with a content along these lines: Note that the bean in the child contexts depends on a bean that is expected to come from the root context. Return new ChildBean1(rootBean, someProperty) Įach of the applications resides in its own root package to avoid collisions when scanning for beans. Import class ChildContext1 ChildBean1 childBean(RootBean String someProperty) Application Context hierarchies provide a way to reuse beans - beans defined in the parent context are accessible in the child contexts.Ĭonsider a contrived use-case of using multiple application contexts and the application context hierarchy - this is to provide two different ports with a different set of endpoints at each of these ports.Ĭhild1 and Child2 are typical Spring Boot Applications, along these lines: package child1 To quickly take a step back - a Spring Application Context manages the lifecycle of all the beans registered with it.

Spring Cloud uses this feature for creating a bootstrap context where properties are loaded up, if required, from an external configuration server, which is made available to the main application context later on. I have a multi-site setup using multiple contexts: Context A Conditions: - Path:This post is simply demonstrating this feature - I have yet to find a good use of it in the projects I have worked on. Spring Boot supports a simple way of specifying a Spring application context hierarchy.
