which methods for which scenarios

- Export
    1. Normal excel export (simple format, moderate amount of data, within 50,000)
        annotation way:  ExcelExportUtil.exportExcel(ExportParams entity, Class<?> pojoClass,Collection<?> dataSet) 
    2. uncertain columns, but also with simple format and small amount of data
        customize way: ExcelExportUtil.exportExcel(ExportParams entity, List<ExcelExportEntity> entityList,Collection<?> dataSet)
    3. big data(greater than 50,000, less than one million) 
        annotation way ExcelExportUtil.exportBigExcel(ExportParams entity, Class<?> pojoClass,IExcelExportServer server, Object queryParams)
        customize way: ExcelExportUtil.exportBigExcel(ExportParams entity, List<ExcelExportEntity> excelParams,IExcelExportServer server, Object queryParams)
    4. complex style, the amount of data not too large
        Template: ExcelExportUtil.exportExcel(TemplateExportParams params, Map<String, Object> map)
    5. Export multiple sheets with different styles at one time
        Template ExcelExportUtil.exportExcel(Map<Integer, Map<String, Object>> map,TemplateExportParams params) 
    6. One template but many copies to export
        Template ExcelExportUtil.exportExcelClone(Map<Integer, List<Map<String, Object>>> map,TemplateExportParams params)
    7. If Template can't satisfy your customization, try HTML
        Build your own html, and then convert it to excel:  ExcelXorHtmlUtil.htmlToExcel(String html, ExcelType type)
    8. Big data(Over millions), please use CSV
        annotation way: CsvExportUtil.exportCsv(CsvExportParams params, Class<?> pojoClass, OutputStream outputStream)
        customize way: CsvExportUtil.exportCsv(CsvExportParams params, List<ExcelExportEntity> entityList, OutputStream outputStream)
    9. Word Export
        Template: WordExportUtil.exportWord07(String url, Map<String, Object> map)
    10. PDF Export
        Template: TODO 
- Import
    If you want to improve the performance, the concurrentTask of ImportParams will help with concurrent imports;Only support single line, minimum 1000. 
	For some special reading for single cell, you can use the  readSingleCell parameter
    1. no need verification, moderate amount of data, within 50,000
        annotation or map: ExcelImportUtil.importExcel(File file, Class<?> pojoClass, ImportParams params)
    2. the amount of data not too large
        annotation or map: ExcelImportUtil.importExcelMore(InputStream inputstream, Class<?> pojoClass, ImportParams params)
    3. For big data or with lots of importing operations; Less memory, only support single line
       SAX: ExcelImportUtil.importExcelBySax(InputStream inputstream, Class<?> pojoClass, ImportParams params, IReadHandler handler)
    4. Big data(Over millions), please use CSV
        small data: CsvImportUtil.importCsv(InputStream inputstream, Class<?> pojoClass,CsvImportParams params)
        big data: CsvImportUtil.importCsv(InputStream inputstream, Class<?> pojoClass,CsvImportParams params, IReadHandler readHandler)

The difference between XLS and XLSX for Excel Export

1. For export time, XLS is 2-3 times faster than xlsx.
2. For export size, XLS is 2-3 or more times than xlsx.
3. Export need to consider both network speed and local speed.

Packages Guide

1.easypoi -- Parent package
2.easypoi-annotation -- Basic annotation package, action on entity objects, 
                        it's convenient for Maven multi-project management after splitting
3.easypoi-base -- Import and export package, realize Excel Import/Export, Word Export
4.easypoi-web  -- Based on AbstractView, Coupled with spring MVC, greatly simplifies the export function 
5.sax -- Optional, Export uses xercesImpl, Word Export uses poi-scratchpad

If you don't use spring MVC, only easypoi-base is enough.
