EasyPoi Excel和 Word简易工具类
===========================

easypoi功能如同名字easy,主打的功能就是容易,让一个没见接触过poi的人员
就可以方便的写出Excel导出,Excel模板导出,Excel导入,Word模板导出,通过简单的注解和模板
语言(熟悉的表达式语法),完成以前复杂的写法

---------------------------
EasyPoi的主要特点
--------------------------
	1.设计精巧,使用简单
	2.接口丰富,扩展简单
	3.默认值多,write less do more
	4.AbstractView 支持,web导出可以简单明了

---------------------------
什么场景该用哪个方法
---------------------------

- 导出
	    1.正规excel导出 (格式简单,数据量可以,5W以内吧)
	        注解方式:  ExcelExportUtil.exportExcel(ExportParams entity, Class<?> pojoClass,Collection<?> dataSet) 
	    2.不定多少列,但是格式依然简单数据库不大
	        自定义方式: ExcelExportUtil.exportExcel(ExportParams entity, List<ExcelExportEntity> entityList,Collection<?> dataSet)
	    3.数据量大超过5W,还在100W以内
	        注解方式 ExcelExportUtil.exportBigExcel(ExportParams entity, Class<?> pojoClass,IExcelExportServer server, Object queryParams)
	        自定义方式: ExcelExportUtil.exportBigExcel(ExportParams entity, List<ExcelExportEntity> excelParams,IExcelExportServer server, Object queryParams)
	    4.样式复杂,数据量尽量别大
	        模板导出 ExcelExportUtil.exportExcel(TemplateExportParams params, Map<String, Object> map)
	    5.一次导出多个风格不一致的sheet
	        模板导出 ExcelExportUtil.exportExcel(Map<Integer, Map<String, Object>> map,TemplateExportParams params) 
	    6.一个模板但是要导出非常多份
	        模板导出 ExcelExportUtil.exportExcelClone(Map<Integer, List<Map<String, Object>>> map,TemplateExportParams params)
	    7.模板无法满足你的自定义,试试html
	        自己构造html,然后我给你转成excel  ExcelXorHtmlUtil.htmlToExcel(String html, ExcelType type)
	    8.数据量过百万级了.放弃excel吧,csv导出
	        注解方式: CsvExportUtil.exportCsv(CsvExportParams params, Class<?> pojoClass, OutputStream outputStream)
	        自定义方式: CsvExportUtil.exportCsv(CsvExportParams params, List<ExcelExportEntity> entityList, OutputStream outputStream)
        9.word导出
            模板导出: WordExportUtil.exportWord07(String url, Map<String, Object> map)
        10.PDF导出
            模板导出: TODO 
    - 导入 
        如果想提高性能 ImportParams 的concurrentTask 可以帮助并发导入,仅单行,最小1000
        excel有单个的那种特殊读取,readSingleCell 参数可以支持
        1. 不需要检验,数据量不大(5W以内)
            注解或者MAP: ExcelImportUtil.importExcel(File file, Class<?> pojoClass, ImportParams params)
        2. 需要导入,数据量不大
            注解或者MAP: ExcelImportUtil.importExcelMore(InputStream inputstream, Class<?> pojoClass, ImportParams params)
        3. 数据量大了,或者你有特别多的导入操作,内存比较少,仅支持单行
           SAX方式  ExcelImportUtil.importExcelBySax(InputStream inputstream, Class<?> pojoClass, ImportParams params, IReadHandler handler)
        4. 数据量超过EXCEL限制,CSV读取
            小数据量: CsvImportUtil.importCsv(InputStream inputstream, Class<?> pojoClass,CsvImportParams params)
            大数据量: CsvImportUtil.importCsv(InputStream inputstream, Class<?> pojoClass,CsvImportParams params, IReadHandler readHandler)

---------------------------
关于Excel导出XLS和XLSX区别
---------------------------

1.导出时间XLS比XLSX快2-3倍
	2.导出大小XLS是XLSX的2-3倍或者更多
	3.导出需要综合网速和本地速度做考虑^~^
	
---------------------------
几个工程的说明
---------------------------
	1.easypoi 父包--作用大家都懂得
	2.easypoi-annotation 基础注解包,作用与实体对象上,拆分后方便maven多工程的依赖管理
	3.easypoi-base 导入导出的工具包,可以完成Excel导出,导入,Word的导出,Excel的导出功能
	4.easypoi-web  耦合了spring-mvc 基于AbstractView,极大的简化spring-mvc下的导出功能
	5.sax 导入使用xercesImpl这个包(这个包可能造成奇怪的问题哈),word导出使用poi-scratchpad,都作为可选包了
--------------------------
maven
--------------------------
maven库应该都可以了
