の期待されるタイプとパラメータマークアップのためにjava.lang.String型の値を設定するはIllegalArgumentException：あなたは、私は以下の例外を取得、私は以下のクエリを実行するときのjava.math.BigDecimal
public int checkIfQueryExist(String query){
List<Product> products= em.createQuery("SELECT p FROM Product p WHERE p.markup=:markup").
setParameter("markup", query).getResultList();
return products.size();
}
を試みてきました：
Caused by: java.lang.IllegalArgumentException: You have attempted to set a value of type class java.lang.String for parameter markup with expected type of class java.math.BigDecimal from query string SELECT p FROM Product p WHERE p.markup=:markup.

BigDecimalを入力しqueryを変換しようと、あなたは、例外の完全なスタックトレースを投稿することができますか？ – shays10私は完全なスタックトレースを追加しました:)本当に助けに感謝します:) – ShayLay22
