java类：
包 bootSample；

import org.springframework.stereotype.*;
import org.springframework.web.bind.annotation.*;
@Controller
@EnableAutoConfiguration
public class SampleController {

@ResponseBody
String home() {

}
public static void main(String[] args) throws Exception {
SpringApplication.run(SampleController.class, args);
