쿼리

CREATE TABLE T_MEMBER ( MEMBER_SEQ INT NOT NULL AUTO_INCREMENT COMMENT '회원 번호', ACCOUNT VARCHAR(50) NOT NULL COMMENT '계정', PASSWORD VARCHAR(100) NOT NULL COMMENT '비밀번호', NICKNAME VARCHAR(10) NOT NULL COMMENT '닉네임', JOIN_DATE DATETIME NOT NULL COMMENT '가입일자', PRIMARY KEY (MEMBER_SEQ) ) COMMENT='회원' COLLATE='utf8mb4_general_ci' ;

Member.java
회원 도메인 생성

package com.example.domain;

import lombok.Data;

@Data
public class Member {
	
	private int memberSeq;
	private String account;
	private String password;
	private String	nickname;
	private String	joinDate;

}

MemberJoinForm.java : validation을 따로 구현하기 위해
메세지 프로퍼티 추가

package com.example.controller.form;

import javax.validation.GroupSequence;
import javax.validation.constraints.Email;
import javax.validation.constraints.NotEmpty;
import javax.validation.constraints.Pattern;

import org.hibernate.validator.constraints.Length;

import com.example.validation.ValidationSteps;

import lombok.Data;

@Data
@GroupSequence({
	MemberJoinForm.class,
	ValidationSteps.Step1.class,
	ValidationSteps.Step2.class,
	ValidationSteps.Step3.class,
	ValidationSteps.Step4.class,
	ValidationSteps.Step5.class,
	ValidationSteps.Step6.class,
})
public class MemberJoinForm {
	
	@NotEmpty(groups = ValidationSteps.Step1.class, message = "{MemberSaveForm.account.notEmpty}")
	@Email(groups = ValidationSteps.Step2.class, message = "{MemberSaveForm.account.pattern}")
	private String account;

	@NotEmpty(groups = ValidationSteps.Step3.class, message = "{MemberSaveForm.password.notEmpty}")
	@Pattern(regexp = "^(?=.*[A-Za-z])(?=.*\\d)(?=.*[$@$!%*#?&])[A-Za-z\\d$@$!%*#?&]{8,12}$",groups = ValidationSteps.Step4.class, message = "{MemberSaveForm.password.pattern}")
	private String password;
	
	@NotEmpty(groups = ValidationSteps.Step5.class, message = "{MemberSaveForm.nickname.notEmpty}")
	@Length(groups = ValidationSteps.Step6.class, min = 2, max = 10, message = "{MemberSaveForm.nickname.length}")
	private String nickname;


}

MemberMapper.java

package com.example.mapper;

import com.example.controller.form.MemberJoinForm;

public interface MemberMapper {
	
	int selectMemberAccount(String account);
	
	void insertMember(MemberJoinForm form);
	

}

MemberService.java

package com.example.service;

import org.springframework.stereotype.Service;

import com.example.controller.form.MemberJoinForm;
import com.example.mapper.MemberMapper;

import lombok.RequiredArgsConstructor;

@Service
@RequiredArgsConstructor
public class MemberService {
	
	private final MemberMapper memberMapper;
	
	public int selectMemberAccount(String account) {
		return memberMapper.selectMemberAccount(account);
	}
	
	public void insertMember(MemberJoinForm form) {
		memberMapper.insertMember(form);
	}
	

}

MemberController.java

package com.example.controller;

import org.springframework.http.HttpEntity;
import org.springframework.http.HttpStatus;
import org.springframework.http.ResponseEntity;
import org.springframework.stereotype.Controller;
import org.springframework.util.Assert;
import org.springframework.validation.annotation.Validated;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

import com.example.controller.form.MemberJoinForm;
import com.example.service.MemberService;

import lombok.RequiredArgsConstructor;

@Controller
@RequestMapping("/member")
@RequiredArgsConstructor
public class MemberController {
	
	private final MemberService memberService;
	
	@GetMapping("/form")
	public String form() {
		return "/member/form";
	}
	
	@PostMapping("/join")
	@ResponseBody
	public HttpEntity<Boolean> join(@Validated MemberJoinForm form) {
		// 계정 중복체크 : true면 사용중인 계정
		boolean isUseAccount=memberService.selectMemberAccount(form.getAccount()) > 0 ;
		Assert.state(!isUseAccount, "이미 사용중인 계정입니다");
		memberService.insertMember(form);
		
		return new ResponseEntity<Boolean>(true, HttpStatus.OK);
	}
	
	
	/**
	 * 가입 완료 화면
	 * @return
	 */
	@GetMapping("/join-complete")
	public String joinComplete() {
		return "/member/join-complete";
	}

}

HttpEntity와 ResponseEntity의 차이?

ResponseEntity : 사용자의 HttpRequest에 대한 응답데이터를 포함하는 클래스, HttpStatus, HttpHeaders, HttpBody를 포함한다. HttpEntity를 상속받으며, RestTemplate 및 @Controller메서드에 사용하고 있다.

HttpEntity : HTTP요청 또는 응답에 해당하는 HttpHeader와 HttpBody를 포함하는 클래스.
HttpEntity 클래스를 상속받아 구현한 클래스가 RequestEntity, ResponseEntity 클래스이다.
