Java 冬眠虫？

我的代码是：

16:59:08,082  INFO org.springframework.test.context.transaction.TransactionalTestExecutionListener:274 - Began transaction (1): transaction manager [org.springframework.orm.hibernate3.HibernateTransactionManager@f90137]; rollback [true]java.lang.IndexOutOfBoundsException: Remember that ordinal parameters are 1-based!

在这里很难找到问题：）

基于序号1表示参数从1开始计数（不是从0开始）。我通常倾向于使用setParameter（String，Object）方法，不依赖于顺序，而是依赖于查询参数的名称

所以答案是不，这不是一个bug。它可能在JPA规范的某个地方提到过。

您还没有显示HQL，但无论如何，这条消息都是误导性的。Hibernate参数在setParameter方法中从0开始，如中所述。这就是为什么使用setParameter（i，arg[i]）时它会起作用。请记住，如果参数的args和no不相同，您也会收到此消息，这可能是为了提醒有关元数据的信息，但会使开发人员感到困惑

我编辑了两次。。很难格式化..呃..代码是：dao.list（“from History where id=？”，0,120213），正如我所说的，这个消息是误导性的。您的q.setParameter（i，args[i]）是正确的。我想知道是否有这么多的++表示接受：）？如果是，请告诉SOaha，这意味着打印：）len（++++…）次：），因此hibernate内核应该正确地注意它：“0-base”而不是1-base

public List<T> list(final String hql,final int start, final int limit,final Object ...args) {
    return hibernateTemplate.executeFind(new HibernateCallback<List<T>>() {
        public List<T> doInHibernate(Session session) throws HibernateException, SQLException {
            Query q = session.createQuery(hql).setFirstResult(start).setMaxResults(limit);
            if(args!=null&&args.length>0){
                for (int i = 0; i < args.length; i++) {
                    q.setParameter(i+1, args[i]);
                }
            }
            return (List<T>) q.list();
        }

    });
}

public List<T> listJPA(final String hql,final int start, final int limit,final Object ...args) {
    return hibernateTemplate.executeFind(new HibernateCallback<List<T>>() {
        public List<T> doInHibernate(Session session) throws HibernateException, SQLException {
            javax.persistence.Query q = entityManagerFactory.createEntityManager().createQuery(hql).setFirstResult(start).setMaxResults(limit);
            if(args!=null&&args.length>0){
                for (int i = 0; i < args.length; i++) {
                    q.setParameter(i+1, args[i]);
                }
            }
            return (List<T>) q.getResultList();
        }

    });
}
