一、先安装jasper的编写模板工具

二、制作报表模板

1.打开Jaspersoft Studio软件，新建jasper report模板文件：File→new→Jasper Report

2.开始画表

方法1：把传参数据作为List数据取值

方法2：把传参数据作为数据源来取值

三、java传参

1、读取报表模板

2、装载模板数据

3、打印pdf

四、打印效果

五、jrxml、java文件

我这里不涉及数据库数据打印，主要为Java传参List<Map<String,Object>>数据打印，在此提供两种画报表的方法及其对应的Java传参方法，，可以先移步打印效果，再看自己需要选择哦~~~~~~~~

一、先安装jasper的编写模板工具

主要有两个工具Jaspersoft Studio、iReport，个人推荐Jaspersoft Studio

1.安装JaspersoftStudio

链接：https://pan.baidu.com/s/1lCUsRZvqS5smmrdyzImUdA
提取码：7jd5

2.安装jasper的编写工具iReport Design

链接：https://pan.baidu.com/s/1jxTQPQCNmSBARhwJVVonZQ
提取码：s9t8

二、制作报表模板

1.打开Jaspersoft Studio软件，新建jasper report模板文件：File→new→Jasper Report

新建模板

2.开始画表

我这里不涉及数据库数据打印，主要为Java传参List<Map<String,Object>>数据打印，在此提供两种方法

方法1：把传参数据作为List数据取值

Parameters->Create Parameters，重命名为dataList：类型为java.util.List

我们想要获取的dataList数据为List类型，需循环获取数据，因此拖拽Text Field文本框到在Detail区域（关于Title，Page，Header，Colum Header等Band这里不多说啦）
- 双击Text Filed，Parameters→dataList→get(int)，此时值为：$P{dataList}.get(int)
- 双击int；Variables→COLUMN_COUNT；因为报表的COLUMN_COUNT是从1开始所以需进行-1操作,此时值为:$P{dataList}.get( {$V{COLUMN_COUNT}-1} )
- 现在获取的是List的一条数据，但我们需要根据key获取HashMap数据，因此还需强制转换
- 最终值为：((HashMap) $P{dataList}.get({$V{COLUMN_COUNT}-1)).get("C1")
重复获取数据操作，最后点击，最终界面如下：

方法2：把传参数据作为数据源来取值

这里为了区分新建模板TestMapList2.jrxml

Parameters->Create Parameters，重命名为dataList：类型为net.sf.jasperreports.engine.data.JRMapCollectionDataSource
拖拽table至detail区域中，然后一路next
双击table
outline→Table→Create Column At The Begining，我这里是五列，所以重复操作五次
双击tableData，Fields→Create Field；这里的名称对应java传参数据Map中的key值
此时我们可以直接拖拽file至table的Detail行中；不嫌麻烦的，也可以拖拽Text Filed文本框至Detail再改值
保存，点击，生成jasper文件，最终界面效果如下：

三、java传参

1、读取报表模板

方法1：读取jrxml文件

String jrxml ="C:\Users\qyl\JaspersoftWorkspace\MyReports\TestMapList.jrxml";
JasperReport report = JasperCompileManager.compileReport(jrxml);

方法2：读取jasper文件

FileInputStream is = new FileInputStream("C:\\Users\\qyl\\JaspersoftWorkspace\\MyReports\\TestMapList.jasper");
JasperReport jasperReport = (JasperReport) JRLoader.loadObject(is);

2、装载模板数据

针对制作报表方法1：

 // 设置模板数据Map<String,Object> map=new HashMap<String,Object>();       List<Map<String, Object>> dataList = new ArrayList<Map<String, Object>>();for (int i = 0; i < 4; i++) {Map<String, Object> rowMap1 = new HashMap<String, Object>();rowMap1.put("C1", "第:" + i + "行1列");rowMap1.put("C2", "第:" + i + "行1列");rowMap1.put("C3", "第:" + i + "行1列");rowMap1.put("C4", "第:" + i + "行1列");rowMap1.put("C5", "第:" + i + "行1列");dataList.add(rowMap1);}//设置paramtersmap.put("dataList",dataList);JasperPrint jasperPrint = null;try {jasperPrint = JasperFillManager.fillReport(jasperReport, map, new JRBeanCollectionDataSource(dataList));           } catch (JRException e) {e.printStackTrace();}

针对制作报表方法2：

//  读取jasper模板文件JasperReport jasperReport = null;try {String jrxml ="C:\\Users\\qyl\\JaspersoftWorkspace\\MyReports\\TestMapList2.jrxml";jasperReport = JasperCompileManager.compileReport(jrxml);//  此行代码可解决部分打印空页问题jasperReport.setWhenNoDataType(WhenNoDataTypeEnum.ALL_SECTIONS_NO_DETAIL);}  catch (JRException e) {e.printStackTrace();}// 设置模板数据Map<String,Object> map=new HashMap<String,Object>();List<Map<String, ?>> dataList = new ArrayList<Map<String, ?>>();for (int i = 0; i < 4; i++) {Map<String, Object> rowMap1 = new HashMap<String, Object>();rowMap1.put("C1", "第:" + i + "行1列"); rowMap1.put("C2", "第:" + i + "行1列");rowMap1.put("C3", "第:" + i + "行1列");rowMap1.put("C4", "第:" + i + "行1列");rowMap1.put("C5", "第:" + i + "行1列");dataList.add(rowMap1);}//设置paramtersmap.put("tableData", new JRMapCollectionDataSource(dataList));JasperPrint jasperPrint = null;try {jasperPrint = JasperFillManager.fillReport(jasperReport, map,  new JREmptyDataSource());} catch (JRException e) {e.printStackTrace();}

3、打印pdf

方法1：

   JRPdfExporter exporter = new JRPdfExporter();try {exporter.setParameter(JRExporterParameter.JASPER_PRINT, jasperPrint);exporter.setParameter(JRExporterParameter.OUTPUT_STREAM, new FileOutputStream("D:\\test1.pdf"));exporter.exportReport();} catch (FileNotFoundException e) {e.printStackTrace();} catch (JRException e) {e.printStackTrace();}

方法2：

JasperExportManager.exportReportToPdfStream(jasperPrint, new FileOutputStream("D:\\test1.pdf"));

五、jrxml、java文件
