:: Spring Boot Remote :: (v2.0.6.RELEASE) The good news is that Spring Boot DevTools configure many properties for your local development out of the box. It is unnecessarily complicated to manage dual sets of configuration by yourself. Another example may be enhanced logging, which can be useful in development but too detailed for production. In development, it can make you miserable by serving old data and not reflecting your latest changes. When in production, it is crucial to depend on various caches (such as templating engine's caches, caching headers for static resources and so on). When developing your application locally, you usually have different configuration needs than when running in production. It is not only useful for developing frontend of your application (in case you distribute it as a part of your Spring app artifact), but it can also be used to monitor and reload output of your REST API.

All you need to do is to install a browser extension, and you're good to go. Spring DevTools automatically launch a local instance of LiveReload server, which monitors your files. It even pre-processes files as needed - that means automatically compiling your SASS or LESS files.

LIVERELOAD ALTERNATIVE UPDATE

LiveReload is a useful tool, which allows you to instantly update your page in browser whenever you make changes in your files such as HTML, CSS, images and more. If your application detects you're running in production, DevTools are automatically disabled.įor this purposes, whenever you run your app as a fully packaged artifact such as a jar with an embedded application server, it is considered to be a production app: The usage of the Spring Boot DevTools is intended only for development, not for production. In Eclipse it is enough just to save your files. In the second combo-box, you can configure reloading all the static resources and templates when IDEA window loses focus (for example when switching to a browser window). Alternatively, you can even select the option to try Hot Swap and restart using DevTools only if Hot Swap failed. In the first combo-box, you can select Update trigger file to trigger DevTools restart whenever you call the Update action. Alternatively, you can open your Spring Boot run configuration and define what happens when you trigger an application update ( Ctrl + F10): You can also configure IDEA to rebuild automatically. When using IntelliJ IDEA, you need to build your project ( Ctrl + F9 or Build → Build Project). What matters is that your IDE actually updates. That means, it is not enough to just change your.

However, this varies depending on your IDE. The restart is triggered whenever there is a change on the classpath. This way restarting your application is much faster than usual and can be a viable alternative to dynamic class reloading with tools such as JRebel. Whenever a restart is triggered, restart classloader is discarded and recreated. Classes you are working with are loaded by restart classloader. Classes which do not change are loaded by the base classloader. Under the hood, Spring DevTools use two classloaders - base and restart.

You change a tiny fraction of your application as the majority of loaded classes are from frameworks and third party libs. You see, when developing an application, you usually change a class or a few and want to check results in your running application for feedback. Fortunately, these restarts are way faster than regular restarts because of a clever trick, which DevTools use. On its own, it wouldn't be so useful as restarts can still take a lot of time. When developing locally, this can be valuable as you don't need to redeploy your application manually. Whenever there is a change in files on your classpath, DevTools automatically restart your running application with the new changes applied. This prevents DevTools dependency being transitively applied to other modules that depend on your project. Note that the dependency is declared as optional.
