//也数计算 @Override public Long getRowCount(DetachedCriteria criteria) { return (Long)this.getHibernateTemplate().findByCriteria(criteria).get(0); } 这里没查到结果，而你去get了

[nikyotensai]

public Long getRowCount(DetachedCriteria criteria) { return (Long)this.getHibernateTemplate().findByCriteria(criteria).get(0); } 这边有问题，为null就get（0）失败
