Blog:Why I don't use lombok

很多人，如同我的同事，似乎觉得lombok这玩意就像神一样的存在，“极大”的方便了项目的开发。我个人是不喜欢这玩意的，很简单的理由：

• 生成getter/setter不是多么困难的事情，IDE很简单就能帮你搞定
• 我不喜欢为自己的IDE装一大堆插件，还要为项目手动开启一下Annotation Processing
• 代码不可见，意味着生成的getters/setter方法，以及@AllArgConstructor生成的方法无法维护

当我把这些想法告诉同事的时候，同事们都觉得我脑子有问题，理由不充分，”lombok只是一个工具，只是没有找到使用工具的最佳实践“。实际上对于技术人员来说，想说服别人是很困难的事情，然而我们为什么要试图说服别人呢？没有多大的意义。相比于工具，有一些更重要的东西就是：经验和原则。

就我的经验，能简单的事情就不要复杂化，越是复杂越难以维护。当然也有人和我是相同的观点，看了一些有意思的关于为什么不用lombok的讨论，贴出来看看：

> OK, let me put it one more time: this has caused me too many bugs. Let me tell > you my past experiences with Lombok, as this is the root of the issue. > > On one project, a new version of the Lombok plugin caused the IDE to > crash (I think this was Intellij). So nobody could work anymore. On > another project, Lombok made the CI server crash (and would have > probably caused the production server to crash), as it triggered a bug > in the JVM On a third project, we achieved 30% performance increase by > recoding the equals/hashcode from Lombok > -> In those 3 projects, some developer gained 5 minutes, and I spent hours recoding everything. So yes, a bad experience. > > Then, for JHipster, the story is also that we can't ask people to > install a plugin on their IDE: > > 1st goal is to have a smooth experience: you generate the app and it > works in your IDE, by default 2nd goal is that you can use whatever > IDE you want. And some people have very exotic things, for example I > just tried https://codenvy.com/ -> no plugin for this one, of course > > Oh, and I just got 2 more: > > Lombok crashing with MapStruct Lombok making Jacoco fails, which meant > the project didn't pass the Sonar quality gate
