You can also find some of his tutorials on his YouTube channel. Thanks to John Thompson for his great video course Spring Framework 5: Beginner to Guru, where he explains this live reloading trick. SpringBoot applies a nice trick, it has one ClassLoader for external libraries (including SpringBoot, SpringFramework etc.) and one for your apps classes and resources and it only reloads the second ClassLoader for a live reload. How can it be faster than a startup of SpringBoot with your app? The whole turnaround usually only takes a few seconds - given that the app itself is small enough. Also one initial manual reload of your app in the browser might be necessary if the config was not yet active when it got initially loaded. If it does not work, try re-loading IntelliJ IDEA - in some cases this seemed to be necessary. Now the build should automatically run, SpringBoot reload the files and resources of your app and shortly after the browser also reload and reflect the changes. Then change something in the source code, be it Java or HTML or anything else. Be careful with the other options in the Registry, though!įinally run your SpringBoot Web project and open it in the Browser. Then activate ".app.running" and press the "close" button. Open the Action popup (Windows and Linux: "Ctrl-Shift-A") and type "Registry" and select the matching entry - see screenshot: We can change this in the IntelliJ IDEA Registry, though. Unfortunately, as you can see in the hint of this setting, this does not work while an application is running. ⚠ The previous step has to be done for each IntelliJ IDEA project again! But in "File / Settings / Compiler" you can activate "Build project automatically" - see screenshot: In either case re-import your dependency config into IntelliJ IDEA (if auto-import is not activated anyway).Īfter you made and changes in your source code, you usually have to run "Build Project" to rebuild your code and restart SpringBoot. In my Chrome browser it does not turn blue when connected, but one can also hover with the mouse pointer over the icon to see it's status.įor Maven, add this dependency to your pom.xml (given the parent-pom is effectively spring-boot-starter-parent with proper version number).įor Gradle, also given you have a spring-boot-starter configuration, add the dependency like this:Ĭompile(":spring-boot-devtools") Add the plugin "LiveReaload" supplied by - see screenshot.Type "lifereload" in the search field on the top left.Open the Google Chrome WebStore with your Chrome browser.Installing the LiveRewiew plugin in Google Chrome (* At the time of writing this article, I am using Firefox Quantum 58.0.2 64bit on Ubuntu Linux 17.10), if you use a different version or get newer plugin versions, the details might vary.) It should turn from black to blue when connected, but if not, also hover with your mouse pointer over the icon to see it's status. To activate the live reload functionality, click the icon to connect. Now you see an icon which looks like a circle made of two arrows around a small circle in your Firefox toolbar - see screenshot. Supports Firefox 57 (Firefox Quantum) by Todd Wolfson. It's the Web extension based version of LiveReload.
