VMWare recently did a survey of over 1500 individuals who use Spring for their "State of Spring 2021", which you can view here.
I read the survey and here are a few things that I learnt from it.
Most users (95%) said that Spring boot increases the developer productivity hugely. Similarly for Spring, overall, most developers agreed that it increases the productivity, more than other Java platforms.
Also, in terms of who knows most about Spring in the team, most people said, they do not have a Spring specialist (34%), which I agree with as well. I think since Spring is a framework, rather than a language, most teams leverage their developers, architects, etc. to be up to date on the new features of Spring, and related projects, rather than having someone dedicated for this role. But this also means, each company, needs to make sure, they give their developers enough space, time and resources, to keep themselves updated of the things happening in the spring community.
For a majority of developers, stackoverflow.com is the way to go for any questions about spring. Spring official documentation on spring.io is a close second. Close to 70% developers still go to the official documentation, which I think is a pretty good number. But VMware acknowledged that they need to focus more on creating demos and improving the docs. The fact that there are multiple resources apart from the official documentation and stackoverflow, it's surprising that they didn't come up as an answer in the survey. If they do publish the raw data, I'm sure we'll find many people who leverage these in their day to day.
Developers love the new shiny modules spring continues to come up with. Half of them said, that's one of the reasons they stay with spring. 39% said they would add new modules to their existing or new projects in the near future. It speaks to the fact that spring keeps up to date with new tech, and keeps adding integrations for them. And who doesn't like a new lego block in their toy box.
Spring data is the most popular module, which suggest a lot of database integrations, mostly relational. Although noSQL also seemed to be close behind with Mongo, Redis and Elastic.
Spring security is as popular as spring data, which is good, since that means people are keeping their applications secure!
About picking a new module, or Spring project, people consider documentation and maturity as the main factors.
Another thing that came out, as a winner, is Kotlin ! More than 90% of the surveyors have a positive view about it and ~60% plan to learn or use it for their projects.
Although REST, SOA has been around for very long, the primary use-case for Spring and Spring Boot is still creating and exposing API to internal and external consumers.
