DBConnection, DBClose 만들어두기

DBConnection

package db;
 
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
 
public class DBConnection {
    public static void initConnection() {
        try {
            Class.forName("oracle.jdbc.driver.OracleDriver");
 
            System.out.println("Driver Loading Success! ");
 
        } catch (ClassNotFoundException e) {
            e.printStackTrace();
        }
    }
    
    public static Connection getConnection() {
 
        Connection conn = null;
 
//        New Oracle : 우클릭 프로퍼티 -> 드라이버 프로퍼티 -> Connection Url 복사 
        try {
            conn = DriverManager.getConnection("jdbc:oracle:thin:@192.168.2.5:1521:xe", "hr", "hr");
 
            System.out.println("DB Connection Success");
 
        } catch (SQLException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
 
        return conn;
 
    }
}
 

 

DBCLOSE

package db;
 
import java.sql.Connection;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;
 
public class DBClose {
    public static void close(PreparedStatement psmt, Connection conn, ResultSet rs) {
 
        try {
            if (psmt != null) {
                psmt.close();
            }
            if(conn != null) {
                conn.close();
            }
            if(rs != null) {
                rs.close();
            }
        } catch (SQLException e) {
            e.printStackTrace();
        }
 
    }
}
