今天在做Struts页面时,遇到了这样的一个错误,很是郁闷啊,从网上找了好多资料,也没有一个好的解决方法,因为Struts设计的页面对Struts的依赖性太大,所以,我一般不用Struts,可是今天的项目,用Struts标签中的<html:select />和<html:optionsCollection />这个两个标签实现起来会更好些, 就在引入了Struts标签,然后就进行编码,本来觉得很容易的问题,可是一直都在报异常,怎么看自己的代码都对,在学校,没有上网,只能硬着头皮找,百思不得其解,直到快6点了,还是没有看出错误,觉得自己做 的肯定对,晚上我女朋友来找的吃的饭,我也没心情和她聊天,我还是在想着这个问题,还以为是把结果存在Context范围内的问题来,想换Session试一下.怎么可能这样呢,真的是太郁闷..........
现在问题解决了,是因为自己没有用<html : form />的问题,难怪呢,这么简单的问题啊,怎么就没有想到呢?这个也不能说是粗心,以前的确没有遇到过这样的问题,经验啊,教训啊,哈哈,高兴啊,不过现在已经晚上22:22分了,呵呵,我也高兴,至少今天晚上不用因为这个问题而睡不着了,呵呵.以后一定要注意了.
