# 46. 创建自己的自动配置

如果你在公司里开发共享库，或者正在开发一个开源或商业库，你可能想开发自己的自动配置（auto-configuration）。自动配置类可以打包到外部jars，并且依旧可以被Spring Boot识别。自动配置可以关联一个“starter”，用于提供自动配置的代码及需要引用的libraries。我们首先讲解构建自己的自动配置需要知道哪些内容，然后讲解[创建自定义starter的常见步骤](https://docs.spring.io/spring-boot/docs/2.0.0.RELEASE/reference/htmlsingle/#boot-features-custom-starter)。

**注** 可参考[demo工程](https://github.com/snicoll-demos/spring-boot-master-auto-configuration)了解如何一步步创建一个starter。

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://jack80342.gitbook.io/spring-boot/iv.-spring-boot-features/46.-creating-your-own-auto-configuration.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
