建立一个父工程，方便接下来分模块尝试spring boot。在父工程中引入spring boot的默认pom：spring-boot-starter-parent。
建立web子模块

引入spring boot的web boot，接下来去定义controller就可以快速建立一个web程序，完全避开web复杂的xml配置。
第一个controller
/**
* Created by lili on 16/5/16.
*/
import org.springframework.boot.*;
import org.springframework.boot.autoconfigure.*;
import org.springframework.stereotype.*;
import org.springframework.web.bind.annotation.*;
@Controller
@EnableAutoConfiguration
public class SampleController {
@RequestMapping("/")
@ResponseBody
String home() {
return "Hello World!";
}
public static void main(String[] args) throws Exception {
SpringApplication.run(SampleController.class, args);
}
}
spring boot的神奇之处就在这里，我们完全可以按照普通java程序一样去run，不需要将web应用打包到诸如tomcat的web容器中就可以启动web应用了。
效果演示
run起来的效果如下：
