ssm框架之将数据库的数据导入导出为excel文件

在这里首先我要将自己遇到的各种问题，以及需求记录下来，做一个备忘，便于以后查看：

需求：主要实现两个功能，将oracle数据库里的数据导出为excel，同时需要将excel表格的数据导入到数据库

环境：springmvc + spring + mybatis + jdk1.7 + poi3.8 + easyui + oracle

在开始的时候，我就各种找ｊａｒ包搭建环境，搭建环境时候所有的ｊａｒ包都没有，只能去各种找，去下载，话不多说，直接上ｊａｒ包，

然后就是各种配置文件，将配置文件现在直接贴出来：

《 applicationContext-dao.xml 》：

日志文件：

　　《log4j.properties 》： 这里不再贴出

springmvc的xml

　　《springmvc.xml》：

最后最重要的就是web.xml ：

　　《web.xml 》：

</init-param>
</servlet>
<servlet-mapping>
<servlet-name>springmvc</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
</web-app>

前端主要使用的是easyui里面的datagried :大致页面如下：

然后就是把jsp页面的代码贴出来：

　　《index.jsp》：

用到了一个工具类（fileutils）：

　　

package com.sword.dataprocess.utils;

import java.io.IOException;
import java.net.URLEncoder;

import sun.misc.BASE64Encoder;

public class FileUtils {
/**
* 下载文件时，针对不同浏览器，进行附件名的编码
*
* @param filename
* 下载文件名
* @param agent
* 客户端浏览器
* @return 编码后的下载附件名
* @throws IOException
*/
public static String encodeDownloadFilename(String filename, String agent)
throws IOException {
if (agent.contains("Firefox")) { // 火狐浏览器
filename = "=?UTF-8?B?"
+ new BASE64Encoder().encode(filename.getBytes("utf-8"))
+ "?=";
filename = filename.replaceAll("\r\n", "");
} else { // IE及其他浏览器
filename = URLEncoder.encode(filename, "utf-8");
filename = filename.replace("+"," ");
}
return filename;
}
}后续会继续补充，未经允许不得转载，欢迎大家多多指正！
