にこのクエリを使用していないよ：範囲の外にHibernateパラメータインデックスが、私は番号のパラメータ
java.sql.SQLException: Parameter index out of range (2 > number of parameters, which is 1).
なぜで
em.createQuery("SELECT p FROM Player p WHERE p.displayName LIKE :q ESCAPE '\\'", Player.class)
.setParameter("q", "%" + query.replace("_", "\\_") + "%")
.setMaxResults(20)
.getResultList()
結果？私はクエリで番号の付いたパラメータを使用していません。私が見る限り、正確にバインドされているもの（q）です。
完全性のためにここに完全なスタックトレースがあります。
