I just announced the new Spring Boot 2 material, coming in REST With Spring:
The 2015 Numbers
Spring 4 came out in December 2013 and it’s been slowly ramping up ever since.
In May 2015, I ran a survey that puts Spring 4 adoption at 65% and Spring Boot adoption at 34%.
The New 2016 Spring Numbers
Last week I just wrapped up a the new “Java and Spring in 2016” survey and received 2253 answers from the community.
In March of 2016, 81.1% of Spring users are using Spring 4 – so definitely a lot of growth since last years 65%:
The Spring Boot Numbers
Spring Boot is even more interesting, growing from 34% last year to 52.8%:
The new numbers are quite interesting, especially the Spring Boot ones which clearly show Boot reached critical mass as it broke the 50% mark.
Out of the full 2255 participants, 388 (17.2%) voted as not using Spring – but keep in mind that my audience is skewed towards Spring developers.
And of course Spring 5 is less than a year away and 4.3 is even closer – so things are going to be just as fast-paced in 2016.
