hibernateを使用してデータベースのテキストフィールドから値を挿入しようとしていますが、機能しません。たとえば、次の列があるProductテーブルに挿入したいとします:idproduct、idprovider、idcategory、name、quantity。
Session session = HibernateUtil.getSessionFactory().openSession();
org.hibernate.Transaction tx = session.beginTransaction();
Product product = new Product();
int idProduct = Integer.parseInt(IdProductTextField.getText());
product.setIdproduct(idProduct);
session.save(product);
tx.commit();
setメソッドにはintパラメーターがあるため、これが挿入される唯一の列です。
ただし、他のすべての列は機能しません。そしてここに問題があります:
Productテーブルに挿入する他の列の他のすべてのsetメソッドには、パラメーターとしてClass変数があります。例えば:
idproviderを挿入する場合、このためのsetメソッドは次のとおりです。
public void setProduct(Product product) {
this.product = product;
}
そして、私はこのメソッドを使用してidproviderを挿入する方法を本当に知りません。
時間がないので、できるだけ早く助けていただければ幸いです。
ここにProduct.javaとProvider.javaを添付します
