[Spring Security] 회원가입하기

[Spring Security] 회원가입하기

DEV/Spring 2020. 8. 20. 16:52

회원가입을 하기 위해 dao,service,serviceImpl,controller에 필요한 메소드를 추가하고 view를 생성한다.

 

package securityexam.dao;

import java.util.HashMap;
import java.util.Map;

import javax.sql.DataSource;

import org.springframework.jdbc.core.BeanPropertyRowMapper;
import org.springframework.jdbc.core.RowMapper;
import org.springframework.jdbc.core.namedparam.BeanPropertySqlParameterSource;
import org.springframework.jdbc.core.namedparam.NamedParameterJdbcTemplate;
import org.springframework.jdbc.core.namedparam.SqlParameterSource;
import org.springframework.jdbc.core.simple.SimpleJdbcInsert;
import org.springframework.stereotype.Repository;

import securityexam.dto.Member;

@Repository
public class MemberDao {
	private NamedParameterJdbcTemplate jdbc;
	private RowMapper<Member> rowMapper = BeanPropertyRowMapper.newInstance(Member.class);
	private SimpleJdbcInsert insertAction;
	
	public MemberDao(DataSource dataSource) {
		this.jdbc = new NamedParameterJdbcTemplate(dataSource);
		this.insertAction = new SimpleJdbcInsert(dataSource)
				.withTableName("member")
				.usingGeneratedKeyColumns("id");
	}
	
	public Member getMemberByEmail(String email) {
		Map<String,Object> map = new HashMap<>();
		map.put("email", email);
		
		return jdbc.queryForObject(MemberDaoSqls.SELECT_ALL_BY_EMAIL, map, rowMapper);
	}

	public long insertUser(Member member) {
		SqlParameterSource params = new BeanPropertySqlParameterSource(member);
		return insertAction.executeAndReturnKey(params).longValue();
	}

	public long insertAdmin(Member member) {
		SqlParameterSource params = new BeanPropertySqlParameterSource(member);
		return insertAction.executeAndReturnKey(params).longValue();				
	}
}

MemberDao.java

 

회원가입폼에서 받아온 데이터를 추가시키기위해서 insertAction을 사용하는데

위 코드처럼 테이블명과 기본키만 지정해주면 sql문을 직접 작성하지않아도 스프링프레임워크가 데이터를 insert해준다.

 

 

package securityexam.service;

import securityexam.dto.Member;
import securityexam.service.security.UserDbService;

//회원관련 정보처리하는 서비스
public interface MemberService extends UserDbService {

	void addMember(Member member, boolean b);

}

MemberService.java

 

package securityexam.service;

import java.util.ArrayList;
import java.util.List;

import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

import securityexam.dao.MemberDao;
import securityexam.dao.MemberRoleDao;
import securityexam.dto.Member;
import securityexam.dto.MemberRole;
import securityexam.service.security.UserEntity;
import securityexam.service.security.UserRoleEntity;

@Service
public class MemberServiceImpl implements MemberService {
	// 생성자에 의해 주입되는 객체이고, 해당 객체를 초기화할 필요가 이후에 없기 때문에 final로 선언하였다.
    // final로 선언하고 초기화를 안한 필드는 생성자에서 초기화를 해준다.
	private final MemberDao memberDao;
	private final MemberRoleDao memberRoleDao;
	
	// @Service가 붙은 객체는 스프링이 자동으로 Bean으로 생성하는데
    // 기본생성자가 없고 아래와 같이 인자를 받는 생성자만 있을 경우 자동으로 관련된 타입이 Bean으로 있을 경우 주입해서 사용하게 된다.
    public MemberServiceImpl(MemberDao memberDao, MemberRoleDao memberRoleDao) {
        this.memberDao = memberDao;
        this.memberRoleDao = memberRoleDao;
    }
	
	@Override
	@Transactional
	public UserEntity getUser(String loginUserId) {
		Member member = memberDao.getMemberByEmail(loginUserId);
		return new UserEntity(member.getEmail(),member.getPassword());
	}

	@Override
	@Transactional
	public List<UserRoleEntity> getUserRoles(String loginUserId) {
		List<MemberRole> memberRoles = memberRoleDao.getRolesByEmail(loginUserId);
		List<UserRoleEntity> list = new ArrayList<UserRoleEntity>();
		
		for(MemberRole memberRole : memberRoles) {
			list.add(new UserRoleEntity(loginUserId, memberRole.getRoleName()));
		}

		return list;
	}

	@Override
	@Transactional
	public void addMember(Member member, boolean b) {
		if(b) {
			memberDao.insertUser(member);
		}else {
			memberDao.insertAdmin(member);
		}
	}

}

MemberServiceImpl.java

 

boolean 타입의 매개변수가 true이면 관리자, false이면 일반 회원 계정으로 추가해주었다.

 

package securityexam.controller;

import java.security.Principal;

import org.springframework.security.crypto.password.PasswordEncoder;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;

import securityexam.dto.Member;
import securityexam.service.MemberService;

@Controller
@RequestMapping(path="/members")
public class MemberController {
	//스프링컨테이너가 생성자를 통해 자동으로 주입한다.
	private final MemberService memberService;
	private final PasswordEncoder passwordEncoder;
	
	public MemberController(MemberService memberService, PasswordEncoder passwordEncoder) {
		this.memberService = memberService;
		this.passwordEncoder = passwordEncoder;
	}
	
	@GetMapping("/loginform")
	public String loginform() {
		return "members/loginform";
	}
	
	@RequestMapping("/loginerror")
	public String loginerror(@RequestParam("login_error")String loginError) {
		return "members/loginerror";
	}
	
	@GetMapping("/joinform")
	public String joinform() {
		return "members/joinform";
	}
	
	//사용자가 입력한 name, email, password가 member에 저장된다.
	@PostMapping("/join")
	public String join(@ModelAttribute Member member) {
		member.setPassword(passwordEncoder.encode(member.getPassword()));
		memberService.addMember(member,false);
		return "redirect:/members/welcome";
	}
	
	@GetMapping("/welcome")
	public String welcome() {
		return "members/welcome";
	}

}

MemberController.java

 

회원가입에 필요한 메소드(joinform, join)와 회원가입 성공시 보여줄 메소드(welcome)를 추가해준다.

 

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

<body>
	<div>
		<h1>회원 가입 폼</h1>
		<div>
			<form method="post" action="join">

		</div>
	</div>

</body>
</html>

joinform.jsp

 

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>welcome</title>
</head>
<body>
<h1>회원가입 성공</h1>
</body>
</html>

welcome.jsp

 

 

웹 어플리케이션을 실행한 후 http://localhost:8080/securityexam/members/joinform 를 입력한다.

 

회원가입 폼에 데이터를 기입하고 회원가입을 클릭하면 /members/welcome으로 넘어간다.

데이터베이스를 확인하면 데이터도 잘 추가된 것을 확인할 수 있다!
