1、建立一個javabean對象
import java.io.Serializable;
public class GoodPrint implements Serializable{
private static final long serialVersionUID = 1L;
private String goodName;
private String goodNo;
private String barcode;
private java.math.BigDecimal quantity;
private String quantityUnit;
public GoodPrint(){
}
public GoodPrint(String goodName,String goodNo,String barcode,java.math.BigDecimal quantity,String quantityUnit){
this.goodName=goodName;
this.goodNo=goodNo;
this.barcode=barcode;
this.quantity=quantity;
this.quantityUnit=quantityUnit;
}
public String getGoodName() {
return goodName;
}
public void setGoodName(String goodName) {
this.goodName = goodName;
}
public String getGoodNo() {
return goodNo;
}
public void setGoodNo(String goodNo) {
this.goodNo = goodNo;
}
public String getBarcode() {
return barcode;
}
public void setBarcode(String barcode) {
this.barcode = barcode;
}
public java.math.BigDecimal getQuantity() {
return quantity;
}
public void setQuantity(java.math.BigDecimal quantity) {
this.quantity = quantity;
}
public String getQuantityUnit() {
return quantityUnit;
}
public void setQuantityUnit(String quantityUnit) {
this.quantityUnit = quantityUnit;
}
}
2、工具--》選項--》classpath，導入\WebContent\WEB-INF\classes ，并打鈎該選項。
3、建立域字段，如下：
一、用ireport建立資料源，如下:
建立一個工廠類，如下：
public class GoodsFactory {
private static GoodPrint[] data={new GoodPrint("GOO1","A","GOO1A",new BigDecimal(10),"M"),
new GoodPrint("GOO2","B","GOO2B",new BigDecimal(20),"PCS")};
public static Object[] getBeanArray() {
return data;
}
public static Collection<?> getBeanCollection() {
return Arrays.asList(data);
}
}
導入工廠類
建立Text報表，如下：
二、背景建立資料源如下，如下：
String root_path=request.getRootPath();
String reportFilePath = root_path + "report/Test.jasper";
List goodList=new ArrayList<Goods>();
goodList.add(new GoodPrint("GOO1","A","GOO1A",new BigDecimal(10),"M"));
goodList.add(new GoodPrint("GOO2","B","GOO2B",new BigDecimal(20),"PCS"));
// JRDataSource dataSource = this.createDataSource();
JRDataSource dataSource = new JRBeanCollectionDataSource(goodList);;
// Map<String, Object> parameters = new HashMap<String, Object>();
// List dataList =new ArrayList();
// parameters.put("dataList", dataList);
JasperReport report = (JasperReport)JRLoader.loadObject(reportFilePath);
JasperPrint jasperPrint = JasperFillManager.fillReport(report, null, dataSource);
String repTpl="123";
JasperExportManager.exportReportToPdfFile(jasperPrint,root_path+"report/123.pdf");
// JasperRunManager.runReportToHtmlFile(root_path+"report/123.pdf",null,null);
//如果建立報表成功，則轉向該報表，其實可以把報表套在架構内，這樣實作比較有意義的報表格式。
response.sendRedirect("report2.html");
// JasperFillManager.fillReport(report, parameters, dataSource);
// OutputStream ouputStream = response.getOutputStream();
// response.setContentType("application/pdf");
// response.setCharacterEncoding("UTF-8");
// String repName=URLEncoder.encode("物料報表", "UTF-8");
// response.setHeader("Content-Disposition", "attachment; filename=\""+repName+"\".pdf");
//
// // 使用JRPdfExproter導出器導出pdf
// JRPdfExporter exporter = new JRPdfExporter();
// exporter.setParameter(JRExporterParameter.JASPER_PRINT, jasperPrint);
// exporter.setParameter(JRExporterParameter.OUTPUT_STREAM, ouputStream);
// exporter.exportReport();
// ouputStream.close();
預覽結果，如下：
