[Spring] Enhancing the Hello World REST API with a Path Variable

Building REST API with Spring Boot (3)

/ @PathVariable /

Let’s understand what is a path parameter

• Path Parameters
  • /users/{id}/todos/{id} => /users/2/todos/200

HelloWorldController.java

@GetMapping(path = "/hello-world/path-variable/{name}")  
public HelloWorldBean helloWorldPathVariable(@PathVariable String name) {  
	return new HelloWorldBean(String.format("Hello World, %s", name));  
}

• @PathVariable 를 이용해서 파라미터 처리
• String.format 으로 문자열 형식 지정
