# 65. 使用Groovy beans DSL开发应用

Spring框架4.0版本对`beans{}`"DSL"（借鉴自[Grails](http://grails.org/)）提供原生支持，你可以使用相同格式在Groovy应用程序脚本中嵌入bean定义。有时这是引入外部特性的很好方式，比如中间件声明，例如：

```java
@Configuration
class Application implements CommandLineRunner {

    @Autowired
    SharedService service

    @Override
    void run(String... args) {
        println service.message
    }

}

import my.company.SharedService

beans {
    service(SharedService) {
        message = "Hello World"
    }
}
```

你可以使用`beans{}`混合位于相同文件的类声明，只要它们都处于顶级，或如果喜欢的话，你可以将beans DSL放到一个单独的文件中。

## 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/vii.-spring-boot-cli/65.-developing-application-with-the-groovy-beans-dsl.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.
