  • 회원가입용 jsp를 만들었다.
  • 이 jsp는 views폴더 밑에 있기때문에 주소로는 접속할수없다.

접속할수있는 Controller를 구성한다.

@Controller
public class MemberController {
	
	
	@RequestMapping(value="/member/joinView.kh", method=RequestMethod.GET)
	public String memberJoinView() {
		
		return "member/join";
		//이름.jsp의 이름을 reutrn으로 만든다
		//이름의 주소를 파악하여 연결한다.
		//WEB-INF/views/member/join.jsp
	}
  • @Controller를 class명 위에 적어줘야 스프링이 controller로 인식하게 된다.
  • @RequestMapping(value="/member/joinView.kh", method=RequestMethod.GET)
    • 메소드명 위에도 이렇게 적어줘야 서블릿과 같은 형식으로 인식한다.
    • value="/member/joinView.kh 메소드를 접속할 주소
    • method=RequestMethod.GET 겟방식으로 접속한다는 뜻
    • WEB-INF/spring/appServlet/servlet-context.xml파일에

		http://www.springframework.org/schema/context https://www.springframework.org/schema/context/spring-context.xsd">

	<!-- DispatcherServlet Context: defines this servlet's request-processing infrastructure -->
	
	<!-- Enables the Spring MVC @Controller programming model -->
	<annotation-driven />

	<!-- Handles HTTP GET requests for /resources/** by efficiently serving up static resources in the ${webappRoot}/resources directory -->
	<resources mapping="/resources/**" location="/resources/" />

      1. 이 bean태그에 의해 return한 값의

        "/WEB-INF/views/ [리턴값] .jsp" 경로로 이동하도록 만들어져있다.

        그렇기때문에 컨트롤러에서 join이라고 리턴했다면

        "/WEB-INF/views/join.jsp" 으로 자동연결되는 것이다.

폼에서 값을 입력받고 그 값을 post형식으로 controller로 보낸다

@RequestMapping(value = "/member/register.kh", method=RequestMethod.POST)
	public String memberJoin(
			@RequestParam("memberId") String memberId,
			@RequestParam("memberPwd") String memberPwd,
			@RequestParam("memberName") String memberName,
			@RequestParam("memberEmail") String memberEmail,
			@RequestParam("memberPhone") String memberPhone,
			@RequestParam("post") String post,
			@RequestParam("address") String memberAddress){
		
		Member member = new Member(memberId,memberPwd,memberName,memberEmail,memberPhone,post+" , "+memberAddress);
		
		int result = mService.registerMember(member);
		if(result>0){
			
			return "redirect:/home.kh";
			
		}else {
			
		}
		
	
		return"";
	}
  • 방금 controller처럼 @RequestMapping(value = "/member/register.kh", method=RequestMethod.POST) 를 이용해 이동할 주소와 방식을 메소드위에 부여한다.
  • public 반환값 메소드명() : 이 괄호안에 입력받은 값과 저장할 변수명을 넣어준다.
  • 아래에 Member 변수에 넣은 값은
    public class Member {

	private String memberId;
	private String memberPw;
	private String memberName;
	private String memberEmail;
	private String memberPhone;
	private String memberAddress;
	private Date endrollDate;
	private Date updateDate;
	private String status;
	
 

	public Member(String memberId, String memberPw, String memberName, String memberEmail, String memberPhone, String memberAddress) {
		super();
		this.memberId = memberId;
		this.memberPw = memberPw;
		this.memberName = memberName;
		this.memberEmail = memberEmail;
		this.memberPhone = memberPhone;
		this.memberAddress = memberAddress;
	}
}
  • 이런식으로 메소드를 오버라이드 해서 만든것이다, (게터세터 생략함 실제로는 있음)
  • post변수가 없기때문에 post는 post+" , "+memberAddress 이런식으로 문자열을 더해서 memberAddress에 더하였다.

이제 service와 store클래스로 가서 값을 저장하자

@Autowired
	private MemberService mService;
  • service클래스로 이동하기전에 controller클래스에서 다음과 같이 service클래스를 정의하였다.
  • @Autowired 를 해주어보내면 Logic클래스와 연결하지 않아도 결합을 약하게 하여 메소드로 값을 전송하는것이 가능하다.

ServiceImpl

@Service
public class MemberServicImpl implements MemberService{
	
	@Autowired
	private SqlSessionTemplate session;
	@Autowired
	private MemberStore mStore;
	

	@Override
	public int registerMember(Member member) {
		
		int result=mStore.insertMember(session, member);
		
		return result;
	}
}
  • 클래스 명 위에 반드시 @Service를 넣어줘야 정상적으로 impl 클래스에서 실행된다.
  • SqlSessionTemplate와 Store클래스를 @Autowired 를 해준뒤 변수로 선언한다.

StoreLogic

@Repository //반드시 해줘야함
public class MemberStoreLogic implements MemberStore {

	@Override
	public int insertMember(SqlSession session, Member member) {
		int result = session.insert("MemberMapper.insertMember",member);
		return result;
	}
  • 이제 Mapper안에 있는 쿼리문의 값을 받아 database에 전송하고 성공/실패 반환값을 받으면된다.

Mapper

  • src/main/resources폴더에 mapper폴더를 만들고 member-mapper라는 xml을 생성하였다.
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper
  PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
  "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="MemberMapper">
<insert id="insertMember">

insert into member_tbl values(#{memberId}, #{memberPw},#{memberName}, #{memberEmail}, #{memberPhone}, #{memberAddress},default,default,default )

</insert> 
</mapper>
  • 규칙은 이전과 동일하다. 오타를 많이 내서 제법 틀렸다… 페이지 상단에 !DOCTYPE mapper값을 꼭 붙여넣어준다

SqlSession설정하기

  • 데이터베이스와 연결할수있는 세션을 구성해야 한다! 아니면 연결이 안된다.
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://www.springframework.org/schema/beans https://www.springframework.org/schema/beans/spring-beans.xsd">

	<!-- Root Context: defines shared resources visible to all other web components -->
	<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
		<property name="driverClassName" 	value="oracle.jdbc.driver.OracleDriver"></property>
		<property name="url" 				value="jdbc:oracle:thin:@localhost:1521:xe"></property>
		<property name="username" 			value="SPRING"></property>
		<property name="password" 			value="SPRING"></property>

	</bean>
	
	<bean id="sqlSession" class="org.mybatis.spring.SqlSessionFactoryBean">
		<property name="configLocation" value="classpath:mybatis-config.xml"></property>
		<property name="dataSource" ref="dataSource"></property>
	</bean>
	
	<bean id="sqlSessionTemplate" class="org.mybatis.spring.SqlSessionTemplate">
		<constructor-arg ref="sqlSession"></constructor-arg>
	</bean>
	
</beans>
  • src/main/WEB-INF/spring에 있는 root-context.xml이다
  • 이 파일을 수정하여 sql세션으로 만든다
  • 연결을 관리하기때문에 하나라도 오타가나면 연결이 안된다

마이바티스를 이용하여 mapper연결하기

  • src/main/resources/에 있는 Mybatis-config.xml이다
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE configuration
  PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
  "http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
<mappers>
<mapper resource="mappers/member-mapper.xml"></mapper>
</mappers>
</configuration>
  • 이 파일이 mappers와 mapper태그를 이용하여 mamber-mapper에 접속하도록 경로를 안내한다.
