SSI兑现 excel 与ORACLE 之间的导入导出 _Web前端

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

<script>
  function interExcel(){
     window.location.href="interExcel.action"
  }
  
  function goExcelToOracle(){

      <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>
