[Spring] @RequestBody vs @RequestParam

@RequestBody vs @RequestParam

@RequestBody

• JSON 형식의 데이터로 받는다.
• 변수명 상관없이 단일 데이터(Map, Object)로 받는다.

@RestController
@RequestMapping(value = "/test")
public class TestController {
	
	@RequestMapping(value = "/testRequestBody", method = RequestMethod.POST) 
	public void testRequestBody(@RequestBody String param) {
	
		System.out.println("param : " + param);
		System.out.println("text : " + param.get("TEXT"));
	
	}

}

 

▶ Postman Test

 

• [ URL ]
  http://localhost:8080/yeyo/test/testRequestBody.do
• [ Method ]
  POST
• [ Header ]
  Content-Type : application/json
• [ Body ]
  {"TEXT" : "HELLO"}
• [ Result ]
  param : {TEXT=HELLO}
  text : HELLO

@RequestParam

• JSON 형식의 데이터로 받을 수 없다.
• URL 상에서 데이터를 찾는다.
• 데이터의 보낼 때 변수 명과 받을 때 변수 명이 일치해야 한다.

@RestController
@RequestMapping(value = "/test")
public class TestController {
	
	@RequestMapping(value = "/testRequestParam", method = RequestMethod.POST) 
	public void testRequestParam(@RequestParam String text, @RequestParam Map<String, String> param) {
	
		System.out.println("text : " + text);

		System.out.println("param : " + param);
		System.out.println("number : " + param.get("number"));
	
	}

}

 

▶ Postman Test

 

• [ URL ]
  http://localhost:8080/yeyo/test/testRequestParam.do?text=HELLO&number=5
• [ Method ]
  POST
• [ Header ]
  Content-Type : application/x-www-form-urlencoded
• [ Result ]
  text : HELLO
  param : {text=HELLO, number=5}
  number : 5
