I recently built a small prototype using Spring Boot. It wasn’t much of a site, just two forms and two reports. As it was only being demonstrated locally, there was no need to worry about deployment and hosting. What’s fascinating is how many different technologies were used in such a simple piece of development:
- Java 8
- Spring Boot
- Spring Security
- Spring Data
Obviously, it’s great how easy it is to use so many different technologies together: building software and handling dependencies through gradle is much easier than doing it by hand; using Spring Data to handle persistence saves a huge amount of time and configuration.
Having said that, a full-stack demo in Java has involved a huge number of technologies – 19 in total. Not all of these require competency (and in some, like Angular, I’d like to know a lot more). Some, like flyway or jacoco could be ignored – although I’d rather have them in place early than add them later.
When I first leaned Java it was relatively straightforward. My first job required Java, HTML, CVS, make, JSP, JDBC and MySQL. I wouldn’t want to return to that era – the applications I produce now are far more sophisticated than anything we could have done back in 2000. But I do wonder how easy it is for new developers to gain confidence and competence in so many tools. Consider how much harder it would be to get a simple site up-and-running in Java compared with PHP.
Which poses an interesting question – how does a new developer get to the point where he or she can produce something interesting? And how can we know that we are using each of these 19 technologies competently and securely?
