ireport? 中增加圖片，添加上屬性，但是運行時報錯如下，是屬性logoPath沒有聲明到map中
| 1. Parameter not found : logoPath net.sf.jasperreports.engine.design.JRValidationException: Report design not valid : ????? 1.

解決辦法：（1）添加圖片屬性以流的方式傳給map
//打印模板地址inputStream = classLoader.getResourceAsStream("template/policy0507tdfb.jrxml");InputStream url = classLoader.getResourceAsStream("photo/top.png");paramMap.put("logoPath",url);paramMap.put("templetPath", inputStream);paramMap.putAll((HashMap)getOffParamsC(printrespvo));listMap.add(paramMap);PrintUtil.printReportPdfMore(listMap,1,response);并且在模板中缺少配置，打開policy0507tdfb.jrxml文件，添加
<parameter name="logoPath" class="java.io.InputStream" isForPrompting="false"/>
即完成。
