ireport利用javabean做数据源?? 创建javabean1.创建DailySales.java,一个简单VO bean。import?java.io.Serializable; public?class?DailySales?implements?Serializable { ????private?static?final?long?serialVersionUID?= 1L; ????private?String?productNo?; ????private?String?productName?; ????private?int?number?; ????private?int?money?; ????private?int?id?; ??? ????public?DailySales(String productNo, String productName,?int?number,?int?money) ??? { ???????this?.?productNo?= productNo; ???????this?.?productName?= productName; ???????this?.?number?= number; ???????this?.?money?= money; ??? } ??? ????public?String getProductNo() ??? { ???????return?productNo?; ??? } ????public?void?setProductNo(String productNo) ??? { ???????this?.?productNo?= productNo; ??? } ????public?String getProductName() ??? { ???????return?productName?; ??? } ????public?void?setProductName(String productName) ??? { ???????this?.?productName?= productName; ??? } ????public?int?getNumber() ??? { ???????return?number?; ??? } ????public?void?setNumber(?int?number) ??? { ???????this?.?number?= number; ??? } ????public?int?getMoney() ??? { ???????return?money?; ??? } ????public?void?setMoney(?int?money) ??? { ???????this?.?money?= money; ??? } ????public?int?getId() ??? { ???????return?id?; ??? } ????public?void?setId(?int?id) ??? { ???????this?.?id?= id; ??? }?? } 2.?创建?DailySalesDataSource.java,?这是报表的数据源。这个类实现了?jasperreports?中提供的数据源接口?JRDataSource,?实现其中的两个方法?:next()?和?getFieldValue(JRField field)?。 import?net.sf.jasperreports.engine.JRDataSource; import?net.sf.jasperreports.engine.JRException; import?net.sf.jasperreports.engine.JRField; ? public?class?DailySalesDataSource?implements?JRDataSource { ????/** ??? ??*?测试数据，实际项目中是动态获取，也不一定是数组，可以是其它的数据类型?. ??? ??*/ ????private?Object[][]?data?= ?????? { ?????????? {??货号?1?,??物品１??, 1,1000}, ?????????? {??货号?2?,??物品?2?, 2,2000}, ?????????? {??货号?3?,??物品?3?, 3,3000}, ?????????? {??货号?4?,??物品?4?, 4,4000}, ?????????? {??货号?5?,??物品?5?, 5,5000}, ?????????? {??货号?6?,??物品?6?, 6,6000}, ?
