Here are the results of the new Java 8 / Spring 4 / Spring Boot Adoption Survey: http://t.co/ylEBUBmaLh (over 1500 votes) — Baeldung (@baeldung) June 1, 2015

Java developers are a dynamic, ever changing bunch.

Over the past couple of weeks, I ran an industry survey here on Baeldung, to see how Java 8, Spring 4 and the newer Spring Boot are adopted and used in the industry.

We got over 1500 answers to the survey – leading to some very cool numbers:

Java 8 Adoption

Let's start with Java, where we numbers are as follows:

38% – Java 8

48.5% – Java 7

13.5% – Java 6

The community is clearly moving to Java 8 at a very fast pace – a Typesafe survey had Java 8 adoption hovering at around 26% back in October of 2014.

We are now at almost 40% adoption in May of 2015 – only 7 months later – which is quite impressive.

Spring 4 Adoption

Spring 4 has been released in December of 2013. Let's see how much it has been adopted across the industry today:

65% – Spring 4

32.5% – Spring 3

2.5% – Spring 2

The numbers are very clear – the ecosystem is moving to Spring 4.

Back in June of 2014 – almost 1 year ago – adoption looked quite different:

37% – Spring 4

– Spring 4 57% – Spring 3

– Spring 3 6% – Spring 2

Spring Boot Adoption

Finally – Spring Boot was released back in April of 2014. Let's see it has been adopted over this past year:

34% – Using Spring Boot Now

66% – Not Yet

Conclusion

The earlier releases – Java 7 and Spring 3 – are clearly on a downward trend but do have a solid part of the market. What's interesting though is that the older versions – Java 6 and Spring 2 are nearly gone or down to single digits.

Overall, it looks like the pace of adoption is strong for both Java 8 and the newer Spring technologies.
