실무에서는 무조건 VO와 DAO가 나누어져 있음

LoginBean
Bean은 VO랑 DAO랑 합쳐져 있는 클래스
package test;
// VO랑 DAO가 합쳐져있는 클래스
public class LoginBeanAnswer {
private String mid;
private String mpw;
private boolean flag;
public String getMid() {
return mid;
}
public void setMid(String mid) {
this.mid = mid;
}
public String getMpw() {
return mpw;
}
public void setMpw(String mpw) {
this.mpw = mpw;
}
public boolean isFlag() {
return flag;
}
public void setFlag(boolean flag) {
this.flag = flag;
}
public void check() {
if(this.mid.equals("admin") && this.mpw.equals("1234")) {
this.flag=true;
}
}
}
ModelVO & ModelDAO를 써야 함
ModelVO
package test02;
public class MemberVO {
private String mid;
private String mpw;
public MemberVO() {
this("","");
}
public MemberVO(String mid,String mpw) {
this.mid=mid;
this.mpw=mpw;
}
public String getMid() {
return mid;
}
public void setMid(String mid) {
this.mid = mid;
}
public String getMpw() {
return mpw;
}
public void setMpw(String mpw) {
this.mpw = mpw;
}
@Override
public String toString() {
return this.mid+"님";
}
}
ModelDAO
package test02;
import java.util.ArrayList;
public class MemberDAO {
ArrayList<MemberVO> datas;
public MemberDAO () {
datas = new ArrayList<MemberVO>();
datas.add(new MemberVO ("admin","1234"));
datas.add(new MemberVO("timo","1234"));
datas.add(new MemberVO("kim","1234"));
}
public boolean insert(MemberVO vo) {
return false;
}
public boolean update(MemberVO vo) {
return false;
}
public boolean delete(MemberVO vo) {
return false;
}
public ArrayList<MemberVO> selectAll(MemberVO vo) {
return datas;
}
public MemberVO selectOne(MemberVO vo) {
for(MemberVO mVO : datas) {
if(mVO.getMid().equals(vo.getMid()) && mVO.getMpw().equals(vo.getMpw())) {
//기존 데이터 보존
MemberVO data=new MemberVO(mVO.getMid(),mVO.getMpw()); //애초에 생성할때 이렇게 만든당
return data;
}
}
return null;
}
}
