+ * @Controller - Indicates that an annotated class is a "Controller" (e.g. a web controller). This annotation serves as a specialization of @Component.
+ * @EnableAutoConfiguration - This annotation tells Spring Boot to "guess" how you want to configure Spring, based on the jar dependencies that you have added.
+ * 
+ * @RequestMapping - Map the url pattern to a method
+ * @ResponseBody - Annotation that indicates a method return value should be bound to the web response body.
