# 71.1. 重新打包存档

使用`org.springframework.boot.loader.tools.Repackager`可以将一个存在的存档重新打包，这样它就变成一个自包含的可执行存档。`Repackager`类需要提供单一的构造器参数，该参数指向一个存在的jar或war包。你可以使用两个可用的`repackage()`方法中的一个来替换原始的文件或写入新的目标，在repackager运行前还可以指定各种配置。

## 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/viii.-build-tool-plugins/71.-supporting-other-build-systems/71.1.-repackaging-archives.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.
