本文详细介绍了在使用JasperReports开发报表时遇到的中文显示问题及其解决方案，包括引入itext-asiain等依赖、设置字符样式及字体属性、打包上传至私库的过程，并提供代码示例。

最近第一次使用jasper画报表，遇到中文无法显示的问题。通过在网上收集的材料，现总结一下几点：包括里边遇到的许多坑

1、首先在tibco jaspersoft开发时加入itex-asiain-5.2.0.jar；itext-asiancmaps-5.1.1.jar。导入lib库里；

2、在自己的jasper文件中的中文字符地方设置字符样式；

必须设置报表上各显示对象的相关属性,各属性设置说明如下:
    Font        name:    宋体 (中文字体)
    PDF font name:   STSong-Light
    PDF  Encoding: UniGB-UCS2-H（注意这个地方，如果使用UniGB-UCS2-V会显示字体竖着显示）
    PDF   Embeded: √

    注意:此三项的设置必须确保iTextAsian.jar亚洲语言包已经包含在项目中,否则出现编译错误；

附上一段设置：

<staticText>
   <reportElement x="80" y="0" width="370" height="40" uuid="e6f13996-a54b-49dd-aeb3-026650924bcb"/>
   <textElement textAlignment="Center">
      <font fontName="宋体" size="23" pdfFontName="STSong-Light" pdfEncoding="UniGB-UCS2-H" isPdfEmbedded="true"/>
   </textElement>
   <text><![CDATA[出库单]]></text>
</staticText>

3、将itex-asiain-5.2.0.jar自己打包上传到自己的maven库里，打包方式参考：

https://blog.youkuaiyun.com/zl834205311/article/details/78086692?depth_1-utm_source=distribute.pc_relevant.none-task&utm_source=distribute.pc_relevant.none-task

注意：上传的是自己的私库，如果有账号密码记得修改自己本地的setting.xml，设置账号密码

<server>
<id>releases</id>
<username>userName</username>
<password>password</password>
</server>
<server>
<id>snapshots</id>
<username>userName</username>
<password>password</password>
</server>

4、自己pom文件引用的依赖

<!-- 生成pdf所依赖的包 -->
    <groupId>com.itextpdf</groupId>
    <artifactId>itextpdf</artifactId>
    <version>5.5.11</version>
</dependency>
<dependency>
    <groupId>com.itextpdf</groupId>
    <artifactId>itext-pdfa</artifactId>
    <version>5.5.11</version>
</dependency>
<!-- 这个是我自己打包上传的依赖包-->
<dependency>
    <groupId>com.itextpdf</groupId>
    <artifactId>itextasian</artifactId>
    <version>1.5.2</version>
</dependency>
<dependency>
    <groupId>com.itextpdf</groupId>
    <artifactId>itext-asian</artifactId>
    <version>5.2.0</version>
</dependency>
<!-- https://mvnrepository.com/artifact/com.lowagie/itextasian -->
<!-- https://mvnrepository.com/artifact/com.itextpdf/font-asian -->
<dependency>
    <groupId>com.itextpdf</groupId>
    <artifactId>font-asian</artifactId>
    <version>7.1.10</version>
    <scope>test</scope>
</dependency>

5、发布到linux上，找不到字符集，参考解决方案

Font '宋体' is not available to the JVM. See the Javadoc for more details

1、把需要用到的字体（可以直接拷贝windows系统的C:\WINDOWS\Fonts 下的相关字体）拷贝当前项目的classpath下，一般为classes目录下

2、在classpath里添加 jasperreports.properties 属性文件

文件内容为：

net.sf.jasperreports.awt.ignore.missing.font=true

6、附上一段代码供参考

public void printApplyOrder(@RequestParam(name = "orderId",required = true) Long orderId,BladeUser user) {
      HttpServletResponse response = ((ServletRequestAttributes) RequestContextHolder.getRequestAttributes()).getResponse();
      JasperPrint jasperPrint;
      ResApplyDetailVO applyDetailVO = resOrderService.resApplyOrderDetail(orderId);
      if (null == applyDetailVO) {
         throw new ServiceException(resManageService.getExceptionMsg(InventoryConstant.ExceptionMsg.KEY_INVENTORY_ORDER));
      }

      try {

         InputStream inputStream = this.getClass().getResourceAsStream("/jasper/ResApplyOrder.jrxml");

         List<ResOrderDtlVO> resOrderDtlVOS = applyDetailVO.getResOrderDtlVOList();
         JRBeanCollectionDataSource dataSource = new JRBeanCollectionDataSource(resOrderDtlVOS);
         Map<String,Object> params = new HashMap<>();
         if (null != user) {
            R<Tenant> tenantR = sysClient.getTenant(user.getTenantId());
            if (null != tenantR&& ResultCodeConstant.ResponseCode.SUCCESS == tenantR.getCode() && null != tenantR.getData()){
               params.put("companyName",tenantR.getData().getTenantName());
            }

            params.put("operaterName",user.getUserName());
         }

         params.put("orderId",applyDetailVO.getOrderId());
         params.put("applyName",applyDetailVO.getApplyName());
         params.put("operateTime", TimeUtil.getFormattedDate(TimeUtil.getSysDate(),TimeUtil.YYYY_MM_DD_HH_MM_SS));
         params.put("departmentName", applyDetailVO.getApplyDepartment());
         params.put("inventoryName",dictClient.getValue(InventoryConstant.StorageName.CODE,InventoryConstant.StorageName.LOCAL_STORAGE).getData());
         params.put("totalNum",resOrderDtlVOS.size());
         jasperPrint = JasperFillManager.fillReport(JasperCompileManager.compileReport(inputStream), params, dataSource);
         response.setCharacterEncoding("UTF-8");
         response.setDateHeader("Expires", 0); // 清除页面缓存
//        response.setHeader("Content-Disposition",
//                "attachment;" + "filename=" + new String((fileName + "." + suffix).getBytes(), "ISO-8859-1"));
         response.setContentType("application/pdf");
         response.setHeader("Content-Disposition","inline;filename=storeOut.pdf");
         JRPdfExporter pdfExporter = new JRPdfExporter();
         pdfExporter.setExporterInput(new SimpleExporterInput(jasperPrint));
         pdfExporter.setExporterOutput(new SimpleOutputStreamExporterOutput(response.getOutputStream()));
         pdfExporter.exportReport();
      }catch (Exception e) {
         log.error(e.getMessage(), e);
      }

   }
