實例說明JSP打印報表的方法
作者：evan
本文通過實例說明了JSP打印報表的方法。使用JSP打印報表的優勢是模板設計、調整方便，無需在服務器端使用復雜的POI或jxl技術，也無需在客戶端使用ActiveX控件技術，更安全、方便，輕松實現較好的打印效果。
因為ms word和excel的文檔都支持html文本格式，因此可以先用word或excel做好模版，另存為Web頁，然后將該html改成jsp，將數據部分動態填入即可，不用很辛苦的調整格式即可實現JSP打印報表。
word頁面只要在jsp頭設置如下指令：
- < %@page contentType="application/msword;charset=GBK" %>
excel如下：
- < %@page contentType="application/vnd.ms-excel;charset=GBK" %>
使用這種方式客戶端必須安裝有office軟件，用戶訪問時將在ie中直接用word或excel打開該頁面。

JSP打印報表簡單示例：
使用word建立一文檔，畫表格如下：
----------------------------
| 用戶名 | 真實姓名 | 性別 |
----------------------------
| guest | 路人甲 | 男 |
----------------------------
保存為Web頁test.htm， 將test.htm改名為test.jsp，修改其中guest、路人甲、男為從數據庫動態查詢，如下：
- < %@ page contentType="application/msword;charset=GBK" %>
- < %@ page import="java.sql.*" %>
- < html xmlns:o="urn:schemas-microsoft-com:office:office"
