        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">

        (我是萌萌的防止转载不留出处的URL: http://my.oschina.net/blu10phcn/blog/418014 )

        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。
