# 11. 开发你的第一个Spring Boot应用

这一节描述怎样开发一个简单的"Hello World" web应用，以此强调下Spring Boot的一些关键特性。项目采用Maven进行构建，因为大多数IDE都支持它。

**注**：[spring.io](http://spring.io/)网站包含很多Spring Boot"入门"指南，如果你需要特定问题的解决方案，可以先去那瞅瞅。你也可以简化下面的步骤，直接从[start.spring.io](https://start.spring.io/)的依赖搜索器选中`Web` starter，这会生成一个新的项目结构，然后你就可以happy的敲代码了。具体详情参考[文档](https://github.com/spring-io/initializr)。

在开始前，你需要打开终端运行以下命令，确保已经安装好了可用的Java和Maven版本：

```
$ java -version
java version "1.8.0_102"
Java(TM) SE Runtime Environment (build 1.8.0_102-b14)
Java HotSpot(TM) 64-Bit Server VM (build 25.102-b14, mixed mode)
```

```
$ mvn -v
Apache Maven 3.3.9 (bb52d8502b132ec0a5a3f4c09453c07478323dc5; 2015-11-10T16:41:47+00:00)
Maven home: /usr/local/Cellar/maven/3.3.9/libexec Java version: 1.8.0_102, vendor: Oracle Corporation
```

**注**：该示例需要创建单独的文件夹，后续的操作建立在你已创建一个合适的文件夹，并且它是你的当前目录。
