Spring Boot Learning (iii) Building restful APIs and unit tests

The @controller, @RestController, @RequestMapping annotations we used before. If you are unfamiliar with spring MVC and have not tried a QuickStart case, it is advisable to look at the SPRINGMVC annotation first; @Controller: Modifier class, which is used to create an object that handles HTTP requests @RestController: Annotations added after Spring4, the original return of JSON in @controller requires @responsebody to match, If you replace @controller directly with @restcontroller, you do not need to configure @responsebody, which returns the JSON format by default. @RequestMapping: Configuring URL Mappings
