在词源上，术语boilerplate: from http://www.takeourword.com/Issue009.html…

Interestingly, the term arose from the newspaper business. Columns and other pieces that were syndicated were sent out to subscribing newspapers in the form of a mat (i.e. a matrix). Once received, boiling lead was poured into this mat to create the plate used to print the piece, hence the name boilerplate. As the article printed on a boilerplate could not be altered, the term came to be used by attorneys to refer to the portions of a contract which did not change through repeated uses in different applications, and finally to language in general which did not change in any document that was used repeatedly for different occasions.

编程中的样板文件由什么组成?正如其他人可能已经指出的那样，它 只是一大块代码，一遍又一遍地复制，很少或 在这个过程中没有对它做任何改变。

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。

样板文件是优秀程序员所避免的:重复。

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.

“样板代码”是任何看似重复的代码，它们一次又一次地出现，以获得一些看起来应该简单得多的结果。

这是一个主观的定义。

这个术语来源于报纸行业的“标准版”:wiki

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)
