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"> <property name="ireport.zoom" value="1.0"/> <property name="ireport.x" value="0"/> <property name="ireport.y" value="0"/> <queryString> <![CDATA[]]> </queryString> <field name="country" class="java.lang.String"> <fieldDescription><![CDATA[country]]></fieldDescription> </field> <field name="name" class="java.lang.String"> <fieldDescription><![CDATA[name]]></fieldDescription> </field> <columnHeader> <band height="23" splitType="Stretch"> <staticText> <reportElement mode="Opaque" x="0" y="3" width="535" height="15" backcolor="#70A9A9" uuid="4293b033-423d-4706-9a1d-11d62f23efb8"/> <box> <bottomPen lineWidth="1.0" lineColor="#CCCCCC"/> </box> <text><![CDATA[ ]]></text> </staticText> <staticText> <reportElement x="414" y="3" width="121" height="15" uuid="3f499bc9-245d-4241-a842-7edee2fde281"/> <textElement textAlignment="Center" verticalAlignment="Middle"> <font fontName="宋体" isBold="true" pdfFontName="STSong-Light" pdfEncoding="UniGB-UCS2-H" isPdfEmbedded="true"/> </textElement> <text><![CDATA[国家]]></text> </staticText> <staticText> <reportElement x="0" y="3" width="136" height="15" uuid="5bb52fb4-d212-47cc-ba60-baf104f05898"/> <textElement textAlignment="Center" verticalAlignment="Middle"> <font fontName="宋体" isBold="true" pdfFontName="STSong-Light" pdfEncoding="UniGB-UCS2-H" isPdfEmbedded="true"/> </textElement> <text><![CDATA[姓名]]></text> </staticText> <staticText> <reportElement x="36" y="-20" width="469" height="20" uuid="9bcfda11-3c52-4474-8eb5-0a1ce672df74"/> <textElement> <font fontName="宋体" size="16" isBold="true" pdfFontName="STSong-Light" pdfEncoding="UniGB-UCS2-H" isPdfEmbedded="true"/> </textElement> <text><![CDATA[测试报表-中文测试-blu10ph]]></text> </staticText> </band> </columnHeader> <detail> <band height="16" splitType="Stretch"> <staticText> <reportElement mode="Opaque" x="0" y="0" width="535" height="14" backcolor="#E5ECF9" uuid="be2670e4-26f3-4b6e-be34-ebcc23c1ee5d"/> <box> <bottomPen lineWidth="0.25" lineColor="#CCCCCC"/> </box> <text><![CDATA[ ]]></text> </staticText> <textField> <reportElement x="414" y="0" width="121" height="15" uuid="b80edd42-d6d1-4bff-a64e-6b463716fc25"/> <textElement textAlignment="Center" verticalAlignment="Middle"> <font fontName="宋体" pdfFontName="STSong-Light" pdfEncoding="UniGB-UCS2-H" isPdfEmbedded="true"/> </textElement> <textFieldExpression><![CDATA[$F{country}]]></textFieldExpression> </textField> <textField> <reportElement x="0" y="0" width="136" height="15" uuid="24059452-5c9f-40f0-b270-ed22993c5e26"/> <textElement textAlignment="Center" verticalAlignment="Middle"> <font fontName="宋体" pdfFontName="STSong-Light" pdfEncoding="UniGB-UCS2-H" isPdfEmbedded="true"/> </textElement> <textFieldExpression><![CDATA[$F{name}]]></textFieldExpression> </textField> </band> </detail> </jasperReport>

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。
