客制化jasperreport导出html的过程
*
先看一段简单的导出html过程中，修改html头部的例子：【jasperreport6.3.1】
HtmlExporter exporter = new HtmlExporter();
SimpleHtmlExporterConfiguration config=new SimpleHtmlExporterConfiguration();
String header= "<html>\n"+
"<head>\n"+
" <title></title>\n"+
" <meta http-equiv=\"Content-Type\" content=\"text/html; charset=UTF-8\"/>\n"+
" <link rel=\"stylesheet\" type=\"text/css\" href=\"css/jasper.css\" />\n"+
" <style type=\"text/css\">\n"+
" a {text-decoration: none}\n"+
" </style>\n"+
"</head>\n"+
"<body text=\"#000000\" link=\"#000000\" alink=\"#000000\" vlink=\"#000000\" bgcolor=\"gray\">\n"+
"<table width=\"100%\" cellpadding=\"0\" cellspacing=\"0\" 0\">\n"+
"<tr><td width=\"50%\"> </td><td align=\"center\">\n";
config.setHtmlHeader(header);
config.setBetweenPagesHtml("");//设置每页之间没有空行
exporter.setConfiguration(config);
exporter.setExporterInput(new SimpleExporterInput(jasperPrint));
exporter.setExporterOutput(new SimpleHtmlExporterOutput(pdfPath));
exporter.exportReport();*
