Mi configuración de proyecto son Spring MVC, Hibernate 3.2.x, en la base de datos MySQLorg.hibernate.QueryParameterException: No se pudo encontrar el nombre de parámetro
consiguiendo el error siguiente:
org.hibernate.QueryParameterException: could not locate named parameter email
Enfoque # 1:
@Override
public Boolean isExist(String email) {
boolean flag = false;
String hql = "from com.cmgr.beans.UserAccount u where u.email = :email";
List<UserAccount> result = currentSession().createQuery(hql)
.setParameter("email", email)
.list();
UserAccount userAccount = (UserAccount)result.get(0);
if (userAccount!=null && userAccount.getEmail().equalsIgnoreCase(email)) {
flag = true;
}
return flag;
}
