ControllerConfig.java 파일에 @Autowired, @Bean 설정

package config;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

import controller.RegisterController;
import spring.MemberRegisterService;

@Configuration
public class ControllerConfig {

	@Autowired
	private MemberRegisterService memberRegSvc;
	
	@Bean
	public RegisterController registerController() {
		return new RegisterController();
	}
	
}

JSP 파일 설정

index.jsp ( 서버 실행 시 켜지는 jsp )

<%@ page contentType="text/html; charset=utf-8" %>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<!DOCTYPE html>
<html>
<head>
    <title>메인</title>
</head>
<body>
    <p>환영합니다.</p>
    <p><a href="<c:url value="/register/step1" />">[회원 가입하기]</a>
</body>
</html>

step1.jsp ( 약관 동의 체크 )

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>회원가입</title>
</head>
<body>
<h2>약관</h2>
<p>약관 내용</p>
<form action="step2" method="post">
<label>
<input type="checkbox" name="agree" value="true">약관 동의
</label>
<input type="submit" value="다음 단계" />
</form>
</body>
</html>

step2.jsp ( 회원가입 )

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>회원가입</title>

step3.jsp ( 회원가입 완료 후 ID 표시 ) name 값 바꿔서 다른 거 출력 가능
