jasperReport + ireport组合实现报表文件（各种文件格式xsl.pdf,rtf等）的生成导出是目前开源报表中使用的最为广泛的。在平台一期完成之后，而且功能中报表以及数据分析这块是必不可少的，一下展示如何使用JasperReport + ireport导出excel报表。

1.需要.jasper文件作为生成报表的模板，这个文件是由ireport文件编译.jrxml文件之后生成的。这个需要注意的是JasperReport和ireport的版本一定要对应，否则很可能出问题。下面的文件就是.jrxml文件：

<?xml version="1.0" encoding="UTF-8"?>
