SSI实现 excel 与ORACLE 之间的导入导出
1.导入相应的jar包
jxl.jar antlr-2.7.2.jar commons-collections.jar commons-dbcp.jar commons-logging-1.0.4.jar freemarker-2.3.8.jar ibatis-2.3.4.726.jar ognl-2.6.11.jar spring.jar struts2-core-2.0.14.jar struts2-spring-plugin-2.0.14.jar xwork-2.0.7.jar ojbc14.jar
2.页面用freemerk
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">

<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>用户管理</title>
<script>
function interExcel(){
window.location.href="interExcel.action"
}
function goExcelToOracle(){
window.location.href="goExcelToOracle.action"
}
</script>
</head>
<body>
<form>
<table>
<tr><td>ID</td><td>姓名</td><td>密码</td></tr><br />
<#list list?if_exists as user>
<tr><td>${user.id}</td><td>${user.userName}</td><td>${user.password}</td></tr>
</#list>
<tr><td><input type="button" onclick="interExcel()" value="导入到Excel表中"/></td></tr>
<tr><td><input type="button" onclick="goExcelToOracle()" value="Excel导入Oracle数据库"/></td></tr>
</table>
</form>
</body>
</html>
3. web.xml的配置
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">
