一位同事从未听说过这个词,我也无法给出一个确切的定义。对我来说,这一直是一个“我看到什么就知道什么”的例子。

附带问题,这个词是谁发明的?

Boilerplate definition is becoming more global in many other programming languages nowadays. It comes from OOP and hybrid languages that have become OOP and were before procedual have now the same goal to keep repeating the code you build with a model/template/class/object hence why they adapt this term. You make a template and the only things you do for each instance of a template are the parameters to individualize an object this part is what we call boilerplate. You simply re-use the code you made a template of, just with different parameters.

Joshua Bloch有一个关于API设计的演讲,涵盖了糟糕的API如何使样板代码成为必要。(参考样板文件的第46分钟,今天听这个)

从维基百科:

在计算机编程中,样板文件是用来描述必须包含在许多地方且很少或没有更改的代码段的术语。它更常用于被认为是冗长的语言,即程序员必须编写大量代码来完成最少的工作。

所以基本上,你可以把样板代码看作是一种编程语言所需要的文本,在你用这种语言编写的程序中经常用到。

现代语言正在尝试减少它,但旧的语言也有特定的类型检查器(例如OCaml有一个类型推断器,它允许您避免在像Java这样更冗长的语言中作为样板代码的太多声明)

重复的代码只会增加不必要的输入层来完成工作。

这些是必要的吗?

在大多数情况下,这些都是结构和装饰性的标记。它提供了代码、函数和语言的一致性。

因此,对于开发人员来说,它有点多余,因为我们已经见过它很多次了,但它确实向非开发人员和编译器传达了一些实际意义。

In practical terms, boilerplate code is the stuff you cut-n-paste all over the place. Often it'll be things like a module header, plus some standard/required declarations (every module must declare a logger, every module must declare variables for its name and revision, etc.) On my current project, we're writing message handlers and they all have the same structure (read a message, validate it, process it) and to eliminate dependencies among the handlers we didn't want to have them all inherit from a base class, so we came up with a boilerplate skeleton. It declared all the routine variables, the standard methods, exception handling framework — all a developer had to do was add the code specific to the message being handled. It would have been quick & easy to use, but then we found out we were getting our message definitions in a spreadsheet (which used a boilerplate format), so we wound up just writing a code generator to emit 90% of the code (including the unit tests).

您可以将其称为“片段”,或者更准确地称为“片段的集合”。 我认为这个术语是由新闻界和印刷业创造出来的,在那里他们使用实际的“板块”,然后再次将它们用作大块。 在现代互联网上,这是一个正在进行的(恕我冒犯)趋势的一部分,使用花哨的术语来描述简单的东西,以便看起来更时尚和复杂。参见响应性=适应性/流动性。
