JAVA实现数据库数据导入/导出到Excel（POI）

准备工作：

1.导入POI包：POI下载地址http://mirrors.tuna.tsinghua.edu.cn/apache/poi/release/src/（重要）

如下

2.导入Java界面美化包BeautyEye下载地址http://code.google.com/p/beautyeye/downloads/detail?name=beautyeye_lnf_v3.5_all_in_one.zip&can=2&q=（可选）如果不想加入界面美化代码可以把void setlookandfeel()这个方法及其调用去掉

jar在下载解压在文件夹dist目录下

beautyeye_lnf.jar包是个开源的美化Java界面的包，推荐学习做出的Java界面比较美观

BeautyEye L&F简明开发者指南. http://code.google.com/p/beautyeye/wiki/Introduction

3.本案例使用Hiberate下配置Oracle导入导出数据

导出的数据库表为users表

SQL> desc system.users; 
Name               Type                           Nullable              Default Comments 
-----               ------------------                   --------                    ------- -------- 
ID                  NUMBER(10)                                   
NAME             VARCHAR2(50 CHAR)                            
PWORD           VARCHAR2(32 CHAR)                            
EMAIL            VARCHAR2(100 CHAR)        Y

注意Column顺序不能乱

1.ExcelOutandIn.java

ExcelOutandIn主要利用Jtable显示数据库里面的数据

显示效果如图所示
