还在看论坛的朋友们，你们好！我最近刚从大学毕业，开始担任初级开发工程师（目前正努力从资深同事那里汲取尽可能多的知识）。但似乎现实世界和大学里的实践大相径庭。在大学里，我们学习了设计模式，以及领域层、应用层、基础设施层、UI层等各种职责。领域层不应依赖基础设施层或应用层，等等。但我在实际项目中遇到的情况是，领域层依赖于基础设施层，还有个项目应用层直接引用了基础设施层，而且他们还告诉我这是正确的实现方式…… 唉…… 我觉得我上课听得还不错，但现在我开始怀疑，学习这些东西到底值不值得，因为现实世界的情况如此矛盾。当然，我没有资格质疑资深开发人员，但你们觉得呢——大学里那些所谓的“最佳实践”真的都直接被扔进垃圾桶了吗？还是我只是误解了真实的工作环境？

Hello those who still read forums.<p>I have recently graduated from a college and started working as a junior dev (trying to consume as much knowledge from senior colleagues as I can now) and it seems that the real world is kind of a different story compared to the college practice.<p>In the college we've been taught about design patterns and all these responsibilities like domain, application, infrastructure, UI. Domain should never depend on infrastructure or application layer and so on. But the projects I got have domain that depend on infrastructure and another one where application has a reference directly to infrastructure and been told that this is correct implementation... doh..<p>I think I was kind of a good at listening for the lectures, but I now am doubting about, whether it was worth learning stuff at all lol since it's so controversial out there. I am, of course, in no position to question senior dev, but what do you guys think - is it really normal that all the college so called "best practices" go straight to the trash bin or am I just misunderstanding the real-work-like context?
