Java模板导出Excel

为什么使用Apache POI 框架导出Excel？

POI 是Apache 基于Java语言顶级开源项目，功能强大，稳定，符合Office openXML规范，入门简单。

能够处理Microsoft office 大多数文件。如：Word , Excel , PowerPoint。加上Apache的光环，所以是不二之选。

JXL是一套提供对Excel操作的类库，操作效率低，功能较为单一，对函数表达式，导出图片支持不好。

为什么为封装此工具类？

由于公司供应链部门业务需要，对Excel处理这块有较为严苛的要求。为了使导出的Excel保持统一的风格和提高开发效率，从实际项目出发封装了通用自定义导出Excel工具类。

基于POI 3.9 版本，建议读者在使用该工具类的时候升级为最新版本，最新版本对以前老版本的一些Bug做了修复，性能会更好。

此工具类只支持Offece 2007 及以上版本，如果读者要支持2003版本可以对该工具类进行扩展。

功能概述

支持在任意位置填充字符，数字，图片
支持在任意位置填充一行值
支持在任意位置填充列表值
支持设置列宽，行高
支持在任意位置填充标题
支持自定义单元格样式风格

效果预览

1. 定义模板

2.添加模板到项目模板目录

3.执行填充逻辑，生成Excel

填充列表效果：

设计思想

设计原则：简单易用。由于导出模板的多样性和不确定性，则需要封装常用的数据结构和样式风格，由开发人员根据业务需求对数据进行组装填充模板，满足业务需求。

采用策略模式，符合开闭原则。

对象关系

对象	说明
ExportExcelCustom	自定义导出接口类，封装了常用导出excel方式
ExportExcelCustomXlsx	xlsx格式excel导出实现
AbstractExcelData	数据实体抽象基类，抽象通用数据字段
ExcelConfigExt	扩展配置实体，用于扩展其它功能传递参数
ExcelTextData	单列内容实体，支持字符，数字，时间
ExcelTitleData	列表标题实体，支持自定义风格
ExcelRowSignData	单行内容实体
ExcelRowMultiData	列表内容实体
ExcelPictureData	图片内容实体
ExcelFontEnum	通用字体样式枚举
ExcelStyleEnum	通用样式枚举

使用注意点

由于操作Excel文件一般较大，建议对JVM调优，将大对象直接放在老年代，具体调优方式，网上资料很多。

待优化点

没有采用annation的方式

待扩充功能点

1. 基于模板导出，导出一个对象，使用表达式，自动填充字段名（不需要指定%s）支持重复填充

2. 导出一个list自动填充一个列表

3. 样式扩展优化（列表标题自动固定样式）

4.添加函数表达式

5. logo 添加

6. 单元格下拉选择

7. 合并单元格

8. 由于该工具类使用JDK 1.7 ，可以升级到JDK1.8或JDK1.9 使用函数式变成和lambda进行代码结构优化

有兴趣的同学可以对此工具类进行扩展。
