I've used Spring since circa 2008 and better I knew it then more I disliked it. It poorly designed and even worse implemented. I really impressed how Spring guys were able to screw up every single idea they've implemented. They implemented slowest possible DI container (about 10x times slower than reflection-based class istantiation!). They made using string constants as a code and exceptions in business logic a everyday norm - which is just insane. Moreover, classic "business exceptions" (let's keep aside for the moment that this concept should not even exist) assumes that "business exceptions" are checked ones and present in method prototypes. Spring uses "technical exceptions" derived from RuntimeException in the place of "business exceptions" and hides remaining signs of business error handling. In other words, they were able to screw up even the idea which is already screwed up. I'm really, really impressed.
Haha totally agree, Spring is vastly overrated ... the point is of course that back then J2EE was so horrible that Spring felt like an improvement :-) but that doesn't say much, it only proves what an incredibly low bar was set by J2EE.
Maybe it could even be argued that Spring was quite okay in the beginning, but over the years it became more and more bloated and overcomplicated.
And at some point J2EE was improved and simplified so much that it was probably better and simpler (more "lightweight" even) than Spring ... but by then Spring had become totally dominant as the new "incumbent" and J2EE didn't stand a chance anymore.
But even years ago there were already Java frameworks which were much, much better than both J2EE and Spring ... Play (playframework.com) is an example, it does away with all the Servlets and container baggage and is much simpler and easier than either Spring or J2EE.
Well, I understand how Spring achieved it's popularity. I just realize that there are rarely any justification to use it in new projects. For those who can't imagine their project without Spring "magic" there is a modern alternative (Micronaut) which solves significant amount of Spring issues and shifts huge part of run time reflection to compile time.
There are a lot of Java Web frameworks which are better than Spring - Spark, Jooby, Vert.x, etc. Vert.x, for example usually one of the top performers in Techempower benchmarks.
In my spare time I'm working on similar framework which is based on Promise-based asynchronous processing model and asynchronous I/O API present in recent Linux kernels - io_uring. I hope it will be extremely fast while easy to use.

We're a place where coders share, stay up-to-date and grow their careers.
