package hh.proc;

public class Book {
private int id;
private String name;
private double price;
private int bookCount;
private String author;

public int getId(){
return id;
}
public void setId(int id){
this.id=id;
}
public String getName(){
return name;
}
public void setName(String name){
this.name=name;
}
public double getPrice(){
return price;
}
public void setPrice(double price){
this.price=price;
}
public int getBookCount(){
return bookCount;
}
public void setBookCount(int bookCount){
this.bookCount=bookCount;
}
public String getAuthor(){
return author;
}
public void setAuthor(String author){
this.author=author;
}
}

import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.util.ArrayList;
import java.util.List;

public class FindBook {

//	public static void main(String[] args) {
//		findAll();
//	}

public Connection getConnection(){
Connection conn=null;
try{
Class.forName("com.mysql.jdbc.Driver");
String url = "jdbc:mysql://localhost:3306/hh";
String username = "root";
String password = "root";
conn=DriverManager.getConnection(url,username,password);

}catch(ClassNotFoundException e){
e.printStackTrace();
}catch(SQLException e){
e.printStackTrace();
}
return conn;
}

public List<Book> findAll(){
List<Book> list=new ArrayList<Book>();
Connection conn=getConnection();
try{
CallableStatement cs=conn.prepareCall("{call findBook()}");
ResultSet rs=cs.executeQuery();
while(rs.next()){
Book book =new Book();
book.setId(rs.getInt("id"));
book.setName(rs.getString("name"));
book.setPrice(rs.getDouble("price"));
book.setBookCount(rs.getInt("bookCount"));
book.setAuthor(rs.getString("author"));
list.add(book);
}
} catch(Exception e){
e.printStackTrace();
}
return list;
}
}
