关于导出excel报表,网上也是一搜一大把。整理一下,无非就是几种思路,有利用安装excel软件或插件的服务器直接生成,或者直接在客户端生成(通常都是利用excel软件或插件直接在浏览器生成)。反正万变不离其宗,离开excel插件,这个活你还真的干不了,由此你可以看到软件公司尤其是微软的强大。下面贴一个比较简单的导出excel报表的方法。在安装了office2003的机器上,通过ie浏览器可以成功生成excel,而且一直有人在使用。如果你在测试的时候发现这个根本无法使用,请注意,这个很可能和你的机器配置有关,别怀疑代码的正确性。下面就一个利用iBatis开发的例子来简单说明一下。
1、实体类
