![]() You can find the end result of the above project setup (after you’ve installed Spring Loaded and changed the path accordingly of course) in my example GitHub repository.Java Ecosystem, Kotlin, Engineering Management, Sociology of Software Development How to Increase Your JVM Development Productivity Now since it’s open source and I see more people paying attention to Spring Loaded I would not be suprised if multi-module support would be added any time soon. If you just stick to keeping your Java source files within your site or cms project module you should be fine and Spring Loaded is a definitly a very promising alternative. If your Hippo CMS project isn’t that large then this is no problem. jar files or other modules in the project. In our case it can handle the classes within the webapp WEB-INF/classes directory really well, but it will not detect changes made in. I guess this is mainly becase Grails 2 based projects do not make use of a multi-module project setup, but all the code is in one source section. Also Spring Loaded does not yet support multi-module Maven projects. I’ve noticed that if you compare Spring Loaded with JRebel it’s still pretty young with regards to plugins for particular frameworks. This video shows all the steps we’ve done above from beginning till end and shows you a working end result. Within IntelliJ you can do this by just pressing CMD + SHIFT + F9. If you change a JSP or class file from now on, all you need to do is compile and package the change from within your IDE. Now these are actually the only changes required to get started with Spring Loaded and seeing live changes without package and deployment cycles. cargo-maven2-plugin $/contexts/site-context.xml conf/Catalina/localhost/ site.xml If you’re running on Mac OS X and have Homebrew you can just do: The annotations on types/methods/fields/constructors can also be modified and it is possible to add/remove/change values in enum types. ![]() changes to method bodies), Spring Loaded allows you to add/modify/delete methods/fields/constructors. Unlike ‘hot code replace’ which only allows simple changes once a JVM is running (e.g. ![]() It transforms classes at load time to make them amenable to later reloading. Spring Loaded is a JVM agent for reloading class file changes whilst a JVM is running. Getting Spring Loadedīefore we start with adding Spring loaded let’s take a look at what Spring Loaded can help us with. Setting it up with your IDE can be less straightforward and time-consuming. IDE tooling can also help, but has it’s limits. ![]() If you don’t have a license you will have to build, re-package and run a cargo:redeploy to get the latest changes into the running Tomcat instance. By default this archetype comes with a JRebel profile, which you can leverage if you (or your employer) already have a license. Most Hippo CMS projects start from our archetype (i.e. This makes it simple to use for new users, because you don’t have to install an application container first and you only need Java and Maven. Some background informationīuilding a Hippo CMS driven website is usually done with the cargo-maven2-plugin to deploy the CMS and Site (delivery-tier) application into a by Cargo created Tomcat instance. In this post I will explain how you can leverage Spring Loaded to implement your Hippo CMS project in less time. It’s battle tested, open source and free to use. Spring Loaded is used as the reloading system in Grails 2 based projects. One of these alternatives is Spring Loaded. ![]() For developers on those kinds of projects getting a JRebel license is usually a thougher challange, but don’t worry there are alternatives besides using JRebel that can also help you speed up development. For this specific scenario JRebel is excellent and it works really well, but most of the developers I meet are spending time on developing websites with Hippo CMS, which are usually less complex projects. JRebel helps limiting the amount of build, aggregate, package and redeploy cycles needed to test the changes and new features which we add to the CMS. The main reason that we use JRebel is that the the CMS suite itself is build from several multi-module Maven projects. JRebel is a great tool and allows us to do live reloading of source code and enables us to develop the CMS product in a lot less time. At Hippo we use JRebel a lot during the development of our CMS product. ![]()
