DaoImp
public StockHolders getInfoByCode(String stockCode) {
return (StockHolders)this.getHibernateTemplate().get(StockHolders.class,stockCode);
}public boolean updateInfo(StockHolders stockHolders) {
this.getHibernateTemplate().update(stockHolders);
return false;
}

解决方案 »

  1.   

    Action 中属性名与页面input name 一样不？
      

  2.   

    我叻个去
    看的好吃力
    楼主你打下断点跟踪一下呗
    System.out.print(this.getStockCode());
    把这个值打印出来看有没有
    如果没有就去看页面和Action的对应关系是否有问题

    哥哥问题在下面，还有我不是哥们....
    没报错
    我要的结果就是点击修改把那条数据传到update中显示
