Over-engineering Memes

Java devs really looked at design patterns and said "you know what? Let's just keep adding layers until nobody knows what's going on anymore." Started with a simple order interface—totally reasonable. Then came the factory pattern because apparently we can't just instantiate objects like normal people. But wait, we need a factory to create our factories! And naturally, the factory interface needs its own factory. Before you know it, you're 17 layers deep in abstraction, your class names are longer than your actual code, and you're trying to convince yourself that AbstractSingletonProxyFactoryBean is "clean" and "maintainable." The clown makeup getting progressively more ridiculous perfectly captures the mental gymnastics required to justify this level of over-engineering. Enterprise Java in a nutshell: where adding three interfaces and two factories to create a single object is considered best practice.

Enterprise Java developers looked upon the inheritance hierarchy and saw that it was deeply nested, and they said "it is good." Just like those biblically accurate angels with their infinite eyes and spinning wheels of fire, this Spring Boot controller class comes with an inheritance chain so long it could trace its ancestry back to the Big Bang. Seven layers of abstraction deep, implementing approximately 47 interfaces (give or take a dimension), because why have a simple REST controller when you can have ControllerEndpointHandlerMapping that inherits from classes with names longer than a CVS receipt? The "Aware" interfaces at the bottom are the cherry on top—your class needs to be aware of literally everything in the Spring ecosystem. ServletContextAware? Check. EmbeddedValueResolverAware? Obviously. At this point, the class is more aware than a meditation guru. This is what happens when you let enterprise architects cook without supervision.
