Why do I say don't over-rely on or blindly trust unit tests? It starts with a merge request. GitHub's Dependabot keeps your application secure and always up to date, meaning it automatically creates merge requests to change my Maven dependency versions. And so the story begins.
When using the IDEA development tool, sometimes a Spring project's config files application.yml or bootstrap.yml aren't recognized properly — the icon isn't the green little leaf, causing the project to fail to start. At this point we need to manually check IDEA's configuration to fix it.
When using MyBatis, IDEA prompts 'Could not autowire. No beans of 'XXXMapper' type found.' and draws a red squiggly line on the mapper class. The actual reason is that you forgot to add the @Repository annotation to the mapper.
The well-known game company EA (Electronic Arts) made a splash on GitHub, open-sourcing part of the source code of two games in the Command & Conquer series! The two games are: Tiberian Dawn and Red Alert.

Earlier I wrote "Key-Exchange Logic for Encrypting Interface Data in Front-End/Back-End Separated Projects (RSA, AES)", explaining the encryption/decryption strategy when front and back ends exchange data.

Why can't you use double/float for transactions and financial currency in Java? In daily use, floating-point calculations with double/float often produce unexpected results, because binary can't precisely represent most decimal fractions. Today we'll discuss how to do decimal calculations correctly in Java.

The SLF4J warning "Class path contains multiple SLF4J bindings" appears in the run log, for example after referencing sdk.renfei.net in SpringBoot. Actually this is a Jar package conflict; you just need to exclude the conflicting Jar package.
In Vue.js development you'll encounter asynchronous-call scenarios, but sometimes you need to wait for the async to finish before the next step, which is where func().then() comes in.
