使用Maven:

pom.xml配置:

       <dependency>
           <groupId>org.apache.poi</groupId>
            <artifactId>poi</artifactId>
            <version>3.9</version>
        </dependency>
        <dependency>
            <groupId>org.apache.poi</groupId>
            <artifactId>poi-ooxml</artifactId>
            <version>3.9</version>
        </dependency>

项目maven做了限制导入,可以使用

 <repositories>  
        <repository>  
            <id>central</id>  
            <name>Maven Central Repository</name>  
            <url>http://repo1.maven.org/maven2</url>  
            <snapshots>  
                <enabled>true</enabled>  
            </snapshots>  
        </repository>  
    </repositories>  

具体JAVA实现:

这里使用的是from表单提交,为了效果,在List页面中使用的是Iframe,当Action导入完成return的是一个 result地址,所以关键问题是:上传后不能关闭iframe页面;

这里使用一个非常不优雅的方式解决【JQuery版本低,用户群使用IE8.9.10】:使用一个跳转过度页面,在这个过度页面使用js关闭ifarem,和刷新List页面。如下:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%@ include file="/resources/pages/system/inc-easyui.jsp"%>
<html>
<head>
<base href="<%=basePath %>"/>
<title>隐患数据导入</title>
<link href="styles/css/blue.css" type="text/css" rel="stylesheet" />
 <script type="text/javascript">
  $(function(){
//获取父也页面对象 parent.document.getElementById(
cancelBtn).click();
//获取父页面的id="
cancelBtn".使用click()鼠标触发事件。
parent.document.location.reload(); });
</script>
</head>
<body>
</body
</html>
