ireport 中增加图片，添加上属性，但是运行时报错如下，是属性logoPath没有声明到map中

1. Parameter not found : logoPath

net.sf.jasperreports.engine.design.JRValidationException: Report design not valid :

解决办法：（1）添加图片属性以流的方式传给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，打开policy0507tdfb.jrxml文件，添加
