以前只知道用poi导出Excel，最近用了SpringMvc的Excel导出功能，结合jxl和poi实现，的确比只用Poi好，两种实现方式如下： 一、结合jxl实现： 1、引入jxl的所需jar包： <...org.apache.poi.hssf.usermodel.HSSFWorkbook; import org.apache.poi.poifs.filesystem.POIFSFileSystem;...* // getSheetAt: only if workbook is created from an existing document * // HSSFSheet sheet...二、结合POI使用： 1、引入Poi compile(*),...format.setFont(font); return format; } } UP!
