Building web apps can be a daunting task. There are many moving parts: you need to define the structure in HTML and then use CSS to make it look the way you want. For frontend apps, you also need to write the app logic in JavaScript and connect it to your backend over REST. And of course, you also need to implement the…
The “State of Spring 2020” report will be published soon, based on the views and experiences of Spring Boot development experts across the globe. In exchange for 15 minutes of your time to complete the survey, you’ll be among the first to receive the survey report and the insights included in it. Please feel free to share this email with your Spring development colleagues. The survey will close at the end of July.
Thanks for sharing your thoughts and experiences with us! The Spring Team
Hi, Spring fans! How're things? Good? Good. I just finished (virtually) presenting for the always-lovely London Java Community this morning. We spoke about Kotlin and Spring and things. It was good. Thank you so much for having me LJC! I also kicked off the epic JetBrains Java Day Online event last Friday. That was a ton of fun! Thank you Jetbrains. I finally, finally, put some elbow grease into automating a listing of some my activity and so now whenever I publish a new Spring Tips video, a new A Bootiful Podcast podcast, or commit to a new public appearance, I'll have information here on my…
Earlier this month, we released a first milestone of Reactor 2020.0.
This cycle, codename Europium, follows the Dysprosium one (which included reactor-core 3.3.x and reactor-netty 0.9.x).
It includes reactor-core 3.4.0 and reactor-netty 1.0.0.
In this blog post, we'll cover a few highlights of the reactor-core milestone, and briefly mention what's in store for M2.
For reactor-netty, we'll link to a separate blog post here as soon as it is out.
Note also that there is a new versioning scheme in place, which has been adopted accross the Spring portfolio: see the reference guide and this blog post…
Hi, Spring fans! Welcome to another installment of a Bootiful Podcast! In this installment Josh Long (@starbuxman) talks about the week that was and talks to the amazing Spring Data JDBC cofounder Jens Schauder (@jensschauder) about JPA, JDBC, and domain-driven design.
Hi, Spring fans! What a crazy week it's been! How are you? I hope you're safe, healthy, happy.
I'll be speaking later today (Tuesday) at the Accento Digital conference and at the Jetbrains Java Day online event on the 10th (Friday). Both of these should be accessible from EMEA and APJ timezones. I look forward to seeing you there!
We've got a ton of good stuff to get to this week so let's get to it!
-XX:SoftMaxHeapSizeHi, Spring fans! In this installment, Josh Long (@starbuxman) talks to Dr. Yordan Karadzhov about instrumenting and visualizing the Linux Kernel, and understanding what's happening from the perspective of the platform, containers, and cloud-native Spring applications.
Hi, Spring fans! Welcome to another installment of This Week in Spring! What a wonderful week it's been and it's only Tuesday! I spoke to folks in Switzerland on Monday, had a few awesome meetings with folks later, then today spoke to folks in Germany in the morning and then folks in APJ (Singapore, mostly) in the evening. And tomorrow, I'm speaking at the JPoint virtual conference about Bootiful Kotlin. I'd love to see you there!
Now then, we've got a ton of things to look at this roundup so let's get to it!
The recent Spring Framework 5.3 M1 release announcement mentions "Spring MVC comes with PathPattern parsing for efficient URL matching". This post expands on that with more context and detail.
In Spring applications AntPathMatcher is used to identify classpath, file system, remote, and other resources in Spring configuration. It has also been used in Spring MVC to match URL paths. Over time the use of patterns in web applications grew in number and syntax with AntPathMatcher evolving to meet those needs but some pain points remain without a solution:
In web applications, patterns need to be matched many times per request and therefore any gains in performance and efficiency matter. However String pattern matching limits what can be achieved.
Choosing the most specific pattern among several that match a request has proven challenging over the years with no simple ways to make it more predictable without impacting other cases.
Matching a String path to a String pattern makes it difficult to avoid URI encoding issues. For example should the incoming path be decoded first and then matched? That allows for patterns themselves to be declared without encoded characters, but what if the request path contains %2F or %3B which are / and ; respectively? Once decoded those alter the structure of the path making it harder to match reliably. We could leave the request path encoded via UrlPathHelper#urlDecode…
