Overview

This section describes how to generate pdf documents based on jasper reports and data, solutions to Chinese font problems, and formatted output of date and time.

IReport version: 5.2.0

Generate maven dependency for pdf documents

<dependency>    <groupId>net.sf.jasperreports</groupId>    <artifactId>jasperreports</artifactId>    <version>5.2.0</version></dependency>

Here, font-song jar is a self-made font jar package: http://pan.baidu.com/s/1nzmkm.

SQL-based data 1. Configure the data source

  
public void test() throws JRException, IOException, SQLException {    InputStream is = Main.class.getClassLoader().getResourceAsStream("reports/XZFYSQS-query.jasper");    Map<String, Object> parameters = new HashMap<String, Object>();    parameters.put("SQD_SYSID", "4028ca9850d19ccb0150d19cd1ae0000");        Connection conn = ...;    byte[] datas = JasperRunManager.runReportToPdf(is, parameters, conn);    conn.close();}

Data Based on JavaBean 1. Create a JavaBean

package cn.sinobest.jzpt.fzywgz.reports.pojo;public class XZFYSQS_RY {    private java.lang.String SQR;    private java.lang.String XB;    private java.sql.Timestamp CSNY;    ......}

2. Add the compilation path to iReport.

  
public void test() throws JRException, IOException {    InputStream is = Main.class.getClassLoader()            .getResourceAsStream(reports/XZFYSQS-javabean.jasper);    List<XZFYSQS_RY> ryList = new ArrayList<XZFYSQS_RY>();    ryList.add(...);    JRBeanCollectionDataSource dataSource = new JRBeanCollectionDataSource(            ryList);    byte[] datas = JasperRunManager.runReportToPdf(is, null, dataSource);    ...}

Chinese font Solution

When generating pdf content based on the template during programming, Chinese characters may not be printed. The solution is as follows:

1. Add the font jar package: font-song
   Http://pan.baidu.com/s/1NzMkm
2. Chinese font, which can be simplified to simplified Chinese characters, such as,, and .
3. Set Properties of the Chinese component
   Date and Time formatting output

   Right-click TextField and choose Field pattern.

   For the date type, MM always displays 2-digit month, M Displays 1 or 2-digit as needed, and other fields and so on.
