關于導出excel報表，網上也是一搜一大把。整理一下，無非就是幾種思路，有利用安裝excel軟件或插件的服務器直接生成，或者直接在客戶端生成（通常都是利用excel軟件或插件直接在瀏覽器生成）。反正萬變不離其宗，離開excel插件，這個活你還真的干不了，由此你可以看到軟件公司尤其是微軟的強大。下面貼一個比較簡單的導出excel報表的方法。在安裝了office2003的機器上，通過ie瀏覽器可以成功生成excel，而且一直有人在使用。如果你在測試的時候發(fā)現這個根本無法使用，請注意，這個很可能和你的機器配置有關，別懷疑代碼的正確性。下面就一個利用iBatis開發(fā)的例子來簡單說明一下。
