首先说明一下springboot是什么吧！spriangboot是spring独立出来的项目，用于快速搭建服务项目。引用springBoot自己的话：‘’Spring Boot makes it easy to create stand-alone, production-grade Spring based Applications that you can "just run". We take an opinionated view of the Spring platform and third-party libraries so you can get started with minimum fuss. Most Spring Boot applications need very little Spring configuration.“

1. springboot地址：http://projects.spring.io/spring-boot/；
   2、需要下载相应依赖包；
   废话不多说，上demo

```@SpringBootApplication
@EnableAutoConfiguration(exclude = {DataSourceAutoConfiguration.class})
@ImportResource({"classpath:/applicationContext.xml"})
public class Application extends SpringBootServletInitializer{
@RequestMapping("/")
String home() {
return "Hello World!";
}

@RequestMapping("/now")
String hehe() {
    return "现在时间：" + (new Date().toLocaleString());
}

public static void main(String[] args) {
    SpringApplication.run(Application.class, args);
    System.out.println(2);
}

ok，这样就可以启动项目了，直接http：localhost：8080，访问即可！
