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：

1<?xml version="1.0" encoding="UTF-8"?>
2<project xmlns="http://maven.apache.org/POM/4.0.0"
3         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

        引入jasperreports、itext和itext-asian，然后做个模板：

        （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：

1class DataBean {
2    private String name;
3    private String country;
4
5    public String getName() {
6        return name;
7    }
8
9    public void setName(String name) {
10        this.name = name;
11    }
12
13    public String getCountry() {
14        return country;
15    }
16
17    public void setCountry(String country) {
18        this.country = country;
19    }
20}
21
22
23class DataBeanList {
24    public ArrayList<DataBean> getDataBeanList() {
25        ArrayList<DataBean> dataBeanList = new ArrayList<DataBean>();
26
27        dataBeanList.add(produce("Manisha", "India"));
28        dataBeanList.add(produce("Dennis Ritchie", "USA"));
29        dataBeanList.add(produce("V.Anand", "India"));
30        dataBeanList.add(produce("Shrinath", "California"));
31        dataBeanList.add(produce("中文", "中国"));
32        return dataBeanList;
33    }
34
35    /**
36     * This method returns a DataBean object,
37     * with name and country set in it.
38     */
39    private DataBean produce(String name, String country) {
40        DataBean dataBean = new DataBean();
41        dataBean.setName(name);
42        dataBean.setCountry(country);
43        return dataBean;
44    }
45}

        最后编译报表：

1public class TestLocalJasperReports {
2    public static void main(String[] args) {
3        String sourcePath = System.getProperty("user.dir")+ File.separator+"src\\main\\resources\\reports";
4        String sourceFileName = sourcePath+ File.separator+"jasper_report_template.jrxml";
5
6        DataBeanList DataBeanList = new DataBeanList();
7        ArrayList<DataBean> dataList = DataBeanList.getDataBeanList();
8        JRBeanCollectionDataSource beanColDataSource = new JRBeanCollectionDataSource(dataList);
9        Map parameters = new HashMap();
10
11        System.out.println("Compiling Report Design ...");
12        JasperReport jasperReport;
13        JasperPrint jasperPrint;
14        try {
15            jasperReport = JasperCompileManager.compileReport(sourceFileName);
16            jasperPrint = JasperFillManager.fillReport( jasperReport, parameters, beanColDataSource);
17            JasperExportManager.exportReportToPdfFile( jasperPrint, sourcePath+ File.separator+"jasper_report_template.pdf");
18        } catch (JRException e) {
19            e.printStackTrace();
20            System.out.println(e.getMessage());
21        }
22        System.out.println("Done compiling!!! ...");
23    }
24}

        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。
