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。

“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

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)

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; } }
