Spring Boot Technical Discussions - Pt 2

BatchConfiguration.java I am comparatively new to the Spring Boot paradigm. I've only been working with it for a little over 2 years. That time is typical developer time and as a team lead I develop less than the average developer. I say this because my two years has not been heavily Spring Boot development. My division within USAA does an awful lot of Spring Batch development and that makes sense given that financial institutions perform the vast majority of their work after hours. Seriously, what systems can handle billions of transactions in the middle of the business day? Batch jobs are perfect for that in the off peak hours when demand on the systems is lower. When I was first introduced to Spring Batch I wrote a fairly simple system monitor. It basically checked something, went back to sleep, woke up later and checked again. It really wasn'

Simple Spring Boot Technical Answers

In other words they were little weasels, always trying to plan something good for themselves (A two week flight to Hawaii for instance) and they kept it to themselves so that no one else could take the trip from them. I've noticed s/w engineers are particularly bad about it. The secrets go something like this... you> Hey, has anyone run into this weird problem where the Spring Boot jar won't start??? them> Nope... So I thought I'd provide some of the simple answers I've found. When you migrate from Spring Boot 2.x to Spring Boot 2.5.x+ the start of the app may fail due to the fact after Spring Boot 2.5, the architecture creates two jar files, rather than one. This confuses gradle a bit (I can't speak for maven) as to which jar to start and as a result your app won't start. The solution is t

I'm absolutely unashamed of any positions I took but I'm back to focusing on technology and I don't want non-technology posts distracting from my blog.  - John
