jasperreports6.0报表中文问题
最近看了下jasperreports报表，写个helloworld一直出问题,最后发现让编码给坑了。。。
要显示中文的话,需要itext-asian这个库，最开始加上了但是有乱码，以为是库或者字体的问题，最后发现是项目编码默认变GBK了，说好的UTF8呢！！！~
直接发pom.xml：
<?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>cn.blu10ph.test</groupId> <artifactId>TestLocalJasperReports</artifactId> <version>1.0-SNAPSHOT</version> <dependencies> <dependency> <groupId>net.sf.jasperreports</groupId> <artifactId>jasperreports</artifactId> <version>6.0.4</version> </dependency> <dependency> <groupId>com.lowagie</groupId> <artifactId>itext</artifactId> <version>4.2.1</version> </dependency> <dependency> <groupId>com.itextpdf</groupId> <artifactId>itext-asian</artifactId> <version>5.2.0</version> </dependency> </dependencies> </project>
引入jasperreports、itext和itext-asian，然后做个模板：
<?xml version="1.0" encoding="UTF-8"?>
<jasperReport xmlns="http://jasperreports.sourceforge.net/jasperreports" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://jasperreports.sourceforge.net/jasperreports http://jasperreports.sourceforge.net/xsd/jasperreport.xsd" name="jasper_report_template" pageWidth="595" pageHeight="842" columnWidth="555" leftMargin="20" rightMargin="20" topMargin="20" bottomMargin="20" uuid="c5758bb1-3f81-4404-affc-ba3b4d2185f5">

写点填充数据的代码：
class DataBean {
private String name;
private String country;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getCountry() {
return country;
}
public void setCountry(String country) {
this.country = country;
}
}
class DataBeanList {
public ArrayList<DataBean> getDataBeanList() {
ArrayList<DataBean> dataBeanList = new ArrayList<DataBean>();
dataBeanList.add(produce("Manisha", "India"));
dataBeanList.add(produce("Dennis Ritchie", "USA"));
dataBeanList.add(produce("V.Anand", "India"));
dataBeanList.add(produce("Shrinath", "California"));
dataBeanList.add(produce("中文", "中国"));
return dataBeanList;
}
/**
* This method returns a DataBean object,
* with name and country set in it.
*/
private DataBean produce(String name, String country) {
DataBean dataBean = new DataBean();
dataBean.setName(name);
dataBean.setCountry(country);
return dataBean;
}
}
最后编译报表：
public class TestLocalJasperReports {
public static void main(String[] args) {
String sourcePath = System.getProperty("user.dir")+ File.separator+"src\\main\\resources\\reports";
String sourceFileName = sourcePath+ File.separator+"jasper_report_template.jrxml";
DataBeanList DataBeanList = new DataBeanList();
ArrayList<DataBean> dataList = DataBeanList.getDataBeanList();
JRBeanCollectionDataSource beanColDataSource = new JRBeanCollectionDataSource(dataList);
Map parameters = new HashMap();
System.out.println("Compiling Report Design ...");
JasperReport jasperReport;
JasperPrint jasperPrint;
try {
jasperReport = JasperCompileManager.compileReport(sourceFileName);
jasperPrint = JasperFillManager.fillReport( jasperReport, parameters, beanColDataSource);
JasperExportManager.exportReportToPdfFile( jasperPrint, sourcePath+ File.separator+"jasper_report_template.pdf");
} catch (JRException e) {
e.printStackTrace();
System.out.println(e.getMessage());
}
System.out.println("Done compiling!!! ...");
}
}
最近用别的语言用的比较High，忘了在学校怎么被Java的编码坑得了，一时大意害死人啊！~
需要注意的就是项目编码一定要UTF-8，然后是报表要声明字体啊什么的，例如：
<font fontName="宋体" pdfFontName="STSong-Light" pdfEncoding="UniGB-UCS2-H" isPdfEmbedded="true"/>
这个可以使用iReport进行辅助设计。
