样板代码是指可以反复使用的一段代码。另一方面，任何人都可以说它是一段可重用的代码。

这个词实际上来自钢铁行业。

对于一点历史，根据维基百科:

在19世纪90年代，样板版实际上是铸造或冲压成金属，准备印刷，并分发给美国各地的报纸。直到20世纪50年代，成千上万的报纸从美国最大的供应商西部报业联盟那里收到并使用了这种样板文件。有些公司还以样板文件的形式发布新闻稿，这样它们就必须按书面形式打印出来。

根据维基百科:

In object-oriented programs, classes are often provided with methods for getting and setting instance variables. The definitions of these methods can frequently be regarded as boilerplate. Although the code will vary from one class to another, it is sufficiently stereotypical in structure that it would be better generated automatically than written by hand. For example, in the following Java class representing a pet, almost all the code is boilerplate except for the declarations of Pet, name and owner: public class Pet { private PetName name; private Person owner; public Pet(PetName name, Person owner) { this.name = name; this.owner = owner; } public PetName getName() { return name; } public void setName(PetName name) { this.name = name; } public Person getOwner() { return owner; } public void setOwner(Person owner) { this.owner = owner; } }

样板文件是优秀程序员所避免的:重复。

软件开发中的样板对不同的人有不同的含义，但通常是指反复使用的代码块。

在MEAN栈开发中，这个术语指的是通过使用模板来生成代码。它比从头开始手动编码整个应用程序更容易，它提供了代码块的一致性和更少的错误，因为它是干净的，经过测试和验证的代码，而且它是开源的，所以它不断更新或修复，因此它在使用框架或代码生成器时节省了大量时间。有关MEAN stack的更多信息，请点击这里。

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).

样板文件是一种写作单元，可以不作任何更改地反复使用。通过扩展，这种思想有时应用于可重用编程，如“样板代码”
