整合Struts2JasperReportWeb报表应用示例

1、整合Struts2+JasperReport Web报表应用示例 JasperReports作为一种优秀且开源的报表引擎，不利用太可惜了。同时，借助开源的JasperReports模板设计利器iReports，可以可视化的设计报表模板。基于Web的报表在很多项目中都是需要的。而随着Struts2的流行，就应该研究一下在Struts2下如何利用JasperReports进行报表输出。本示例比较简单，采用的数据源即为JavaBean，而没有采用复杂的数据库，其实原理是一样的。只是传递给JasperReports的参数随着连接方式的变化而略加修改而已。一 准备工作所使用的类库及Jar包如下

2、图所示：图1.使用的Jar包开发环境：MyEclipse5.5+Eclipse3.2+JDK5.0+Tomcat5.5+Struts 2.0.6。当然，本该所提供的源代码下载中没有提供相关的lib，因为文件大太，如果需要，请留下email。源代码下载：Struts2AndJasperReport.rar二 设计报表模板本例中采用JavaBean作为数据源，用于显示People对象的一些基本属性，如所在序号、城市、姓名、地址，并对同一城市的人员进行汇总小结显示。至于如何在iReports中设计模板文件，请在网上参考其它文档。这里不再详细解读，或有时间俺再另写文章来具体讲解如何在iReports中

3、设计报表模板。WebRootjasperjasper_template.jrxml代码如下：<?xml version="1.0" encoding="UTF-8"  ?><!- Created with iReport - A designer for JasperReports -><!DOCTYPE jasperReport PUBLIC "/Jasp
