AdminBussinessクラスからDTOに、次にDAOにデータを渡したいとします。クラスDTOとDAOの間のデータの受け渡し
私のデータは、AdminBussinessクラスからDAOまでずっと移動していません。
package com.diariofacil.business;
import com.diariofacil.pojo.Product;
import com.diariofacil.service.DiarioFacilException;
import com.diariofacil.transferobject.ProductTO;
/**

* @author asdrubal
*/
public class AdminBussiness {
public String product, description, code;
public double price;
public int productQuantity;
Product productClass = new Product();
public AdminBussiness() {
}
public AdminBussiness(String product, double price, int productQuantity, String description, String code) {
this.product = product;
this.price = price;
this.productQuantity = productQuantity;
this.description = description;
this.code = code;
}
/*gets and sets*/
public void addProduct(ProductTO productTO) throws DiarioFacilException{
productClass.setNombre(this.getProduct());
productClass.setPrice(this.getPrice());
productClass.setMinimunStock(this.getProductQuantity());
productClass.setDescription(this.getDescription());
productClass.setCode(this.getCode());
productTO.insert(productClass);
}
public void updateProduct(ProductTO productTO) throws DiarioFacilException, Exception {
productClass.setNombre(this.getProduct());
productClass.setPrice(this.getPrice());
productClass.setMinimunStock(this.getProductQuantity());
productClass.setDescription(this.getDescription());
productClass.setCode(this.getCode());
productTO.update(productClass);
}
}
addProductメソッドは追加ではありません。
package com.diariofacil.pojo;
import com.diariofacil.interfaces.Soldable;
import java.io.Serializable;
public class Product extends Item implements Serializable, Soldable {
Provider provider;
Category category;
int minimunStock,id;
public Product(int id,Provider provider, Category category, int minimunStock, String nombre, String description, String code, double price) {
super(nombre, description, code, price);
this.provider = provider;
this.category = category;
this.minimunStock = minimunStock;
}
public Product(String nombre, String description, String code, double price) {
super(nombre, description, code, price);
}
public Product() {
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public Provider getProvider() {
return provider;
}
public void setProvider(Provider provider) {
this.provider = provider;
}
public Category getCategory() {
return category;
}
public void setCategory(Category category) {
this.category = category;
}
public int getMinimunStock() {
return minimunStock;
}
public void setMinimunStock(int minimunStock) {
this.minimunStock = minimunStock;
}
}
package com.diariofacil.transferobject;
import com.diariofacil.pojo.*;
import com.diariofacil.service.DiarioFacilException;
import com.diariofacil.service.*;
import java.io.Serializable;
import java.util.List;
import java.util.logging.Level;
import java.util.logging.Logger;
public class ProductTO implements Serializable{
private ProductDAO dao = new ProductDAO();
public ProductTO() {
}
public void insert(Product product) throws DiarioFacilException {
dao.insert(product);
}
public void delete(Product product) throws DiarioFacilException{
dao.delete(product);
}
public void update(Product product) throws DiarioFacilException, Exception{
dao.update(product);
}
public List<Product> search() throws DiarioFacilException{
return dao.SearchProduct();
}
}
そしてDAO
package com.diariofacil.service;
import com.diariofacil.pojo.*;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.util.ArrayList;
import java.util.List;
public class ProductDAO extends ServiceBase {
private static final String INSERT = "INSERT INTO `product`(`id`,`price`,`description`,"
+ "`stock`,`category`,`seller` VALUES (?,?,?,?,?,?,?)";
private static final String DELETE ="DELETE FROM `diariofacil`.`product`\n" +
"WHERE ID VALUES (?);";
private static final String SELECT ="SELECT `product`.`id`,`product`.`name`"+
"FROM `diariofacil`.`product`;";
private static final String UPDATE = "UPDATE product SET id = ?, price = ?, description = ?, category = ?, seller = ?, minimum_stock "
+ "WHERE id = ?";
public void insert(Product product) throws DiarioFacilException {
this.connect();
try {
PreparedStatement pstmt = this.getConexion().prepareStatement(INSERT);
pstmt.setInt(1, 1);
pstmt.setDouble(2, product.getPrice());
pstmt.setString(3, product.getDescription());
pstmt.setInt(4, product.getMinimunStock());
pstmt.setObject(5, product.getCategory());
pstmt.setObject(6, product.getProvider());
pstmt.execute();
} catch (SQLException ex) {
ex.printStackTrace();
throw new DiarioFacilException("No se puedo insertar el registro.");
} finally {
this.disconect();
}
}
public void update(Product product) throws Exception{
this.connect();
try {
PreparedStatement pstmt = this.getConexion().prepareStatement(UPDATE);
pstmt.setInt(1, product.getId());
pstmt.setDouble(2, product.getPrice());
pstmt.setString(3, product.getDescription());
pstmt.setInt(4, product.getMinimunStock());
} catch (SQLException ex) {
ex.printStackTrace();
throw new Exception("No se pudo actualizar el registro");
} finally {
this.disconect();
}
}
public void delete(Product product) throws DiarioFacilException {
this.connect();
try {
PreparedStatement pstmt = this.getConexion().prepareStatement(DELETE);
pstmt.setInt(1, product.getId());
pstmt.executeUpdate();
} catch (SQLException ex) {
ex.printStackTrace();
throw new DiarioFacilException("No se puedo eliminar el registro.");
} finally {
this.disconect();
}
}
どのように私は、最初のクラスでaddProductメソッドでproductClassにproductToからデータを移動することができますか？
