JasperReports学习�W�记7-applet打印

lanjh — Tue, 15 Oct 2013 08:45:00 GMT

打包applet的class和所需的jar包，�q�加上数字签�?br />

要运行打印的applet需要jasperreports-x.x.x-applet.jar�Q�可以用winrar直接解压�~�了�Q?br />然后把applet�~�辑后的class和解压羃后的文�g攑֜�同一个目录（比如temp�Q�，
在命令提�C�符中输�?jar 命��o打成一个包�Q�例如：jar -cvf stengReport1Applet.jar *
接着开始做数字�{�֐��Q?/p>

(1)生成证书: keytool -genkey -alias printkey -dname "CN=stsoft, OU=stsoft, O=stsoft, L=nc, ST=nc, C=cn" -keystore printstore -keypass supervise -storepass supervise -validity 3650
默认的签名只有半�q�的有效期，�q�里我们�?validity参数讑֮��?0�q�的有效�?br /> (2)导出证书: keytool -export -keystore printstore -alias printkey -file print.cer -storepass supervise
(3)对jar包签名：
jarsigner -keystore printstore stengReport1Applet.jar printkey
jarsigner -keystore printstore commons-collections-2.1.1.jar printkey
jarsigner -keystore printstore commons-digester-2.1.jar printkey
jarsigner -keystore printstore commons-logging-1.1.1.jar printkey
jarsigner -keystore printstore jasperreports-5.2.0.jar printkey
jarsigner -keystore printstore jasperreports-applet-5.2.0.jar printkey
jarsigner -keystore printstore jasperreports-fonts-5.2.0.jar printkey
jarsigner -keystore printstore jasperreports-javaflow-5.2.0.jar printkey

现在在temp下已�l�有了一个stengReport1Applet.jar和一个print.cer�Q�把�q�两个文件拷贝回��目中，记得�q�是攑֜�同一个目录下

�q�行demo�C�Z��中的jasper-webapp�Q�访问print.html和内嵌式viewer.html

JasperReports学习�W�记5-其它数据生成动态的报表�Q�WEB�Q?

lanjh — Tue, 15 Oct 2013 08:07:00 GMT

一、空数据�Q�Empty Datasources�Q?
��是说JRXML文�g里面的内定w��是静态的,直接使用
JREmptyDataSource��p��?br />JasperRunManager.runReportToPdfStream(reportStream,
servletOutputStream, new HashMap(), new JREmptyDataSource());

二、Map数组�Q�Map Datasources�Q?
有的时候数据不一定要从数据库里面来，�q�有可能从Map数组里面来成生Map[]的方�?

private Map[] initializeMapArray()
{
//你可以把数组里面的每个map看成一个对象，��q��于数据库里面的每个字�D?br />HashMap[] reportRows = new HashMap[4];
HashMap row1Map = new HashMap();
HashMap row2Map = new HashMap();
HashMap row3Map = new HashMap();
HashMap row4Map = new HashMap();
row1Map.put("tail_num", "N263Y");
row1Map.put("aircraft_serial", "T-11");
row1Map.put("aircraft_model", "39 ROSCOE TRNR RACER");
row1Map.put("engine_model", "R1830 SERIES");
row2Map.put("tail_num", "N4087X");
row2Map.put("aircraft_serial", "BA100-163");
row2Map.put("aircraft_model", "BRADLEY AEROBAT");
row2Map.put("engine_model", "R2800 SERIES");
row3Map.put("tail_num", "N43JE");
row3Map.put("aircraft_serial", "HAYABUSA 1");
row3Map.put("aircraft_model", "NAKAJIMA KI-43 IIIA");
row3Map.put("engine_model", "R1830 SERIES");
row4Map.put("tail_num", "N912S");
row4Map.put("aircraft_serial", "9973CC");
row4Map.put("aircraft_model", "PA18-150");
row4Map.put("engine_model", "R-1820 SER");
reportRows[0] = row1Map;
reportRows[1] = row2Map;
reportRows[2] = row3Map;
reportRows[3] = row4Map;
return reportRows;
}

生成JRMapArrayDataSource对象
private JRDataSource createReportDataSource()
{
JRMapArrayDataSource dataSource;
Map[] reportRows = initializeMapArray();
dataSource = new JRMapArrayDataSource(reportRows);
return dataSource;
}

三、Map集合

private JRDataSource createReportDataSource()
{
JRMapCollectionDataSource dataSource;
Collection reportRows = initializeMapCollection();
dataSource = new JRMapCollectionDataSource(reportRows);
return dataSource;
}
private Collection initializeMapCollection()
{
ArrayList reportRows = new ArrayList();
HashMap row1Map = new HashMap();
HashMap row2Map = new HashMap();
HashMap row3Map = new HashMap();
HashMap row4Map = new HashMap();
row1Map.put("tail_num", "N263Y");
row1Map.put("aircraft_serial", "T-11");
row1Map.put("aircraft_model", "39 ROSCOE TRNR RACER");
row1Map.put("engine_model", "R1830 SERIES");
row2Map.put("tail_num", "N4087X");
row2Map.put("aircraft_serial", "BA100-163");
row2Map.put("aircraft_model", "BRADLEY AEROBAT");
row2Map.put("engine_model", "R2800 SERIES");
row3Map.put("tail_num", "N43JE");
row3Map.put("aircraft_serial", "HAYABUSA 1");
row3Map.put("aircraft_model", "NAKAJIMA KI-43 IIIA");
row3Map.put("engine_model", "R1830 SERIES");
row4Map.put("tail_num", "N912S");
row4Map.put("aircraft_serial", "9973CC");
row4Map.put("aircraft_model", "PA18-150");
row4Map.put("engine_model", "R-1820 SER");
reportRows.add(row1Map);
reportRows.add(row2Map);
reportRows.add(row3Map);
reportRows.add(row4Map);
return reportRows;
}

JRDataSource dataSource = createReportDataSource();
JasperRunManager.runReportToPdfStream(reportStream,
servletOutputStream, new HashMap(), dataSource);

四、对象数�l�（Java Objects as Datasources�Q�对象JAVABEAN

private JRDataSource createReportDataSource()
{
JRBeanArrayDataSource dataSource;
AircraftData[] reportRows = initializeBeanArray();
dataSource = new JRBeanArrayDataSource(reportRows);
return dataSource;
}

private AircraftData[] initializeBeanArray()
{
AircraftData[] reportRows = new AircraftData[4];
reportRows[0] = new AircraftData("N263Y", "T-11", "39 ROSCOE TRNR
RACER", "R1830 SERIES");
reportRows[1] = new AircraftData("N4087X", "BA100-163", "BRADLEY
AEROBAT", "R2800 SERIES");
reportRows[2] = new AircraftData("N43JE", "HAYABUSA 1", "NAKAJIMA
KI-43 IIIA", "R1830 SERIES");
reportRows[3] = new AircraftData("N912S", "9973CC", "PA18-150",
"R-1820 SER");
return reportRows;
}

//最后servlet里面调用
JRDataSource dataSource = createReportDataSource();
JasperRunManager.runReportToPdfStream(reportStream,
servletOutputStream, new HashMap(), dataSource);

五、对象集�?
和对象数�l�基本上一�?��是最后生成的是JRBeanCollectionDataSource

private JRDataSource createReportDataSource()
{
JRBeanCollectionDataSource dataSource;
Collection reportRows = initializeBeanCollection();
dataSource = new JRBeanCollectionDataSource(reportRows);
return dataSource;
}

JRDataSource dataSource = createReportDataSource();
JasperRunManager.runReportToPdfStream(reportStream,
servletOutputStream, new HashMap(), dataSource);

六、XML数据成生报表�Q�XML as Datasource�Q?br />
JRXmlDataSource xmlDataSource = new JRXmlDataSource(
new BufferedInputStream(getServletConfig().getServletContext()
.getResourceAsStream("/reports/AircraftData.xml")),
"/AircraftData/aircraft");

七、json数据�?

List<Map<String, Object>> list = new ArrayList<Map<String, Object>>();

        Map<String, Object> row1 = new HashMap<String, Object>();
        Map<String, Object> row2 = new HashMap<String, Object>();

        Map<String, Object> row = new HashMap<String, Object>();
        row.put("field1", "001");
        row.put("field2", "张三");
        row.put("field3", "中国上�v");
        row.put("field4", "field4");
        row.put("field5", "field5");
        list.add(row);
        row = new HashMap<String, Object>();
        row.put("field1", "002");
        row.put("field2", "李四");
        row.put("field3", "中国杭州");
        row.put("field4", "field4");
        row.put("field5", "field5");
        list.add(row);
        row = new HashMap<String, Object>();
        row.put("field1", "003");
        row.put("field2", "王五");
        row.put("field3", "中国南昌");
        row.put("field4", "field4");
        row.put("field5", "field5");
        list.add(row);

        row2.put("uAnswer", list);
        row1.put("qNaire", row2);

        JSONObject jsonObject = JSONObject.fromObject(row1);
        String json = jsonObject.toString();

        Map<String, Object> jasperPara = new HashMap<String, Object>();
        jasperPara.put("TITLE", "json数据报表演示样例�Q?0131012�Q?/span>");
        InputStream is = new ByteArrayInputStream(json.getBytes());
        jasperPara.put("JSON_INPUT_STREAM", is);
        jasperPara.put(JsonQueryExecuterFactory.JSON_LOCALE, Locale.CHINA);
        jasperPara.put(JRParameter.REPORT_LOCALE, Locale.CHINA);

json数据

    {"qNaire": {
          "uAnswer": [
            {
              "field1": "001",

JasperReports学习�W�记2-创徏��单的报表例子

lanjh — Tue, 15 Oct 2013 06:55:00 GMT

一、创建简单的jrxml文�g

�q�里可以手动创徏jrxml文�g�Q�也可以使用ireport设计器创�?
1xml version="1.0"?>
2DOCTYPE jasperReport
3PUBLIC "-//JasperReports//DTD Report Design//EN"
4"http://jasperreports.sourceforge.net/dtds/jasperreport.dtd">
5<jasperReport name="FirstReport">
6    <detail>
7        <band height="20">
8            <staticText>
9                <reportElement x="20" y="0" width="200" height="20" />
10                <text>If you see this, it work]]>text>
11            staticText>
12        band>
13    detail>
14jasperReport>

以上是一个简单的JRXML文�g�Q�实际上��是一个标准的XML文�g�Q?lt;jasperReport>是根元素�Q?lt;staticText>表示静态的数据�Q?lt;reportElement>定义�?lt;staticText>的位�|�和宽度,定义了实际的静态数据�?br />
二、把JRXML文�g解析成jasper文�g,文�g��或JasperReport对象

�~�译jrxml生成jasper文�g

JasperCompileManager.compileReportToFile("WebRoot/report/jasperreports_demo.jrxml", "WebRoot/report/lanjh.jasper");

生成文�g��?br />public static void compileReportToStream(InputStream inputStream,OutputStream outputStream)

生成报表对象
public static JasperReport compileReport("WebRoot/report/jasperreports_demo.jrxml")

三、有了JasperReport对象�Q�文件流或jasper文�g之后�Q�就可以用JasperFillManager生成JasperPrint对象,jrprint文�g�Q�jrprint文�g��?

生成JasperPrint 对象
public static JasperPrint fillReport(JasperReport jasperReport,Map parameters, JRDataSource dataSource)

四、��用JasperExportManager导出或显�C?br />JasperExportManager.exportReportToHtmlFile(jasperPrint, "c://1.html");
JasperExportManager.exportReportToPdfFile(jasperPrint, "c://1.pdf");

完整的例�?br />

1 JasperReport jasperReport;
2        JasperPrint jasperPrint;
3        try{
4          jasperReport = JasperCompileManager.compileReport("WebRoot/report/jasperreports_demo.jrxml");
5          jasperPrint = JasperFillManager.fillReport(jasperReport, new HashMap(),new  JREmptyDataSource());
6          JasperExportManager.exportReportToPdfFile(jasperPrint, "c://1.pdf");
7   }
8        catch (JRException e){
9          e.printStackTrace();
10        }
