How To Be More Effective In Spring
I wasn't thinking about being more effective at university. I was more busy to handle new technologies than speeding up compiling or deploying my app. My first job changed my thinking about this topic, it was a big and old project and my changes took effect in approximately 10 minutes. It was depressing because I hate switching a context. In the end, I reduced that time, but still, it took about 3-5 minutes.
When I started to work in CloseIT, I was eager to understand how the app works. Usually, I try it by trial and fail. On the other hand, each build takes time and it disturbs my workflow. I was wondering if there is a way to make it faster. It was my first work experience with Spring framework, but it didn't take a long time to find people with the same problem, and that's how I found the devtools from Spring.
So, how to use the devtools in your application? It's pretty straightforward as finding it.
| <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-devtools</artifactId> <optional>true</optional> </dependency> |
Note: The <optional>true</optional> prevents SpringDevtools from being transitively applied to other modules that use your project.
That's all from me for now. The devtools offers more features as remote support, for example, but I didn't try this on our servers yet. The reason is that I find out a problem, we use drool rules and they don't work together with devtools. For more information see this page.
Another cool feature that I haven't tried yet is a live reload which is used by frontend guys. Simply, it automatically refreshes a browser when a resource is changed. So, you can see how your page looks as you type.
Now, I run out of my notes about testing the devtools. I hope my notes saved you some time, I didn't write a detailed how-to, because you can find more specific information on the official documentation.
