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

<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>
