@RestController
@EnableAutoConfiguration
public class Example {
 
  @RequestMapping("/")
  public String home() {
    return "Hello World";
  }
 
  public static void main(String[] args) {
    /**
     * SpringApplication会自动加载application.properties文件，具体的加载路径包含以下:
     * <p>
     *   1. A <b>/config</b> subdirectory of the current directory;
     *   <p/>
     * <p>
     *   2. The Current Directory
     * </p>
     * <p>
     *   3. A classpath /config package
     * </p>
     * <p>
     *   4. The classpath root.
     * </p>
     */
    SpringApplication.run(Example.class, args);
  }
}
