springframework一直是服务器端开发的一匹野马深受广大开发者的青睐，优点：架构体系成熟、功能丰富、文档教程多；缺点：环境搭建成本较高。
话不多说咋们来看看springboot给我们带来了什么。
准备工作
官方网址：
http://projects.spring.io/spring-boot/
官方文档：
http://docs.spring.io/spring-boot/docs/current/reference/htmlsingle/
现在还有不少公司还用着最原始的copy lib来搭建，如果你在这样的公司工作或许你不知道pom.xml是什么，没关系 赶紧补习一下maven吧，这里我就不多做介绍了百度一下环境搭建资料一大把，同学还来得及...
Idea创建Maven项目扫盲，熟悉的同志直接跳过
idea是个好东西哈～～，没有使用过的可以来尝鲜
第一步没什么好介绍的
第一步，创建
第二步：选择maven
next
第三部：设置GroupId和ArtifactId，然后一直next
设置名称
项目创建完成
完成创建
是骡子是马，咋们拉出来遛一遛。
修改pom.xml
<!-- springboot 核心依赖-->
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.3.5.RELEASE</version>
</parent>
<dependencies>
<!-- web项目必须依赖，主要集成容器相关jar -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
</dependencies>
创建Tomcat启动类
@SpringBootApplication
public class Bootstrap {
public static void main(String[] args) {
ApplicationContext context = SpringApplication.run(Bootstrap.class, args);
if (context instanceof EmbeddedWebApplicationContext) {
int port = ((EmbeddedWebApplicationContext) context).getEmbeddedServletContainer().getPort();
String contextPath = context.getApplicationName();
String url = String.format(Locale.US, "http://localhost:%d%s", port, contextPath);
System.out.println("url: " + url);
}
}
}
配置文件：
springboot除了支持properties还支持yml配置，如果需要修改boot配置信息可以直接在
src/main/resources中
添加application.yml或者application.properties
配置属性列表
启动日志：

到现在为止一个简单的springboot功能已经跑起来了待续....
有兴趣的可以直接git clone 一份https://github.com/cyzaoj/spring-boot-scaffold自行研究一下，同时欢迎各位大神丢砖拍板。
