1.자료형으로 파라미터 받는 방법

	/**
	 * 자료형으로 파라미터 받는 방법
	 * @param id
	 * @param code
	 * @param model
	 */
	@GetMapping("/example1")
	public void example1(@RequestParam String id, @RequestParam String code, Model model) {
		model.addAttribute("id" ,id);
		model.addAttribute("code" ,code);
	}

<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Example</title>
</head>
<body>
<h1>example1</h1>
<h2> id : {{id}}</h2>
<h2> code : {{code}}</h2>
</body>
</html>

2.Map을 활용한 파라미터 받는 방법

	/**
	 * Map을 활용한 파라미터 받는 방법
	 * @param paramMap
	 * @param model
	 */
	@GetMapping("/example2")
	public void example2(@RequestParam Map<String,Object> paramMap, Model model) {
		model.addAttribute("paramMap" ,paramMap);
	}

<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Example</title>
</head>
<body>
<h1>example2</h1>
<h2> paramMap.id : {{paramMap.id}}</h2>
<h2> paramMap.code : {{paramMap.code}}</h2>
</body>
</html>

3.Class를 활용한 파라메터 받는 방법

	/**
	 * Class를 활용한 파라메터 받는 방법
	 * @param parameter
	 * @param model
	 */
	@GetMapping("/example3")
	public void example3(ExampleParameter parameter, Model model) {
		model.addAttribute("parameter" ,parameter);
	}

ExampleParameter

import lombok.Data;

@Data
public class ExampleParameter {

	private String id;
	private String code;
}

<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Example</title>
</head>
<body>
<h1>example3</h1>
<h2> parameter.id : {{parameter.id}}</h2>
<h2> parameter.code : {{parameter.code}}</h2>
</body>
</html>

4.@PathVariable 을 활용한 파라메터 받는 방법

	/**
	 * @PathVariable 을 활용한 파라메터 받는 방법
	 * @param id
	 * @param code
	 * @param model
	 * @return
	 */
	@GetMapping("/example4/{id}/{code}")
	public String example4(@PathVariable String id, @PathVariable String code, Model model) {
		model.addAttribute("id" ,id);
		model.addAttribute("code" ,code);
		return "/example/parameter/example4";
	}

<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Example</title>
</head>
<body>
<h1>example4</h1>
<h2> id : {{id}}</h2>
<h2> code : {{code}}</h2>
</body>
</html>

5. Stirng[] 배열을 받는방법

	/**
	 * Stirng[] 배열을 받는방법
	 * @param ids
	 * @param model
	 * @return
	 */
	@GetMapping("/example5")
	public String example5(@RequestParam String[] ids, Model model) {
		model.addAttribute("ids" ,ids);		
		return "/example/parameter/example5";
	}

<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Example</title>
</head>
<body>
<h1>example5</h1>
<h2> ids :  {{ids}}
</h2> 
{{#ids}}
	{{.}}
{{/ids}}
</body>
</html>

6.json Map 으로 받는 방법

	/**
	 * example6 json Form 페이지 이동
	 */
	@GetMapping("/example6/form")
	public String example6() {
		return "/example/parameter/example6/form";
	}
	
	
	/**
	 * json Map 으로 받는 방법

		Map<String, Object> resultMap=new HashMap<String, Object>();
		resultMap.put("requestBody", requestBody);
		resultMap.put("result", true);		
		return resultMap;
	}

<!DOCTYPE html>
<html>
