FusionCharts 动态生成XML数据问题

导读:前台页面: var chart = new FusionCharts("${ctx}/plugins/FusionCharts/Charts/Column3D.swf","ChartId","904","300"); chart.setDataURL("${ctx}/info/getDataInfo"); 后台代码: try { String beginYear = super.getParameter("beginYear"); String endY
前台页面: var chart = new FusionCharts("${ctx}/plugins/FusionCharts/Charts/Column3D.swf","ChartId","904","300"); chart.setDataURL("${ctx}/info/getDataInfo"); 后台代码: try { String beginYear = super.getParameter("beginYear"); String endYear = super.getParameter("endYear"); StringBuffer wsdwFileContent = new StringBuffer("<?xml version="1.0" encoding="UTF-8"?><chart caption="" + beginYear + "年至" + endYear + "年" baseFontSize="12" palette="2" bgColor="#99CCFF,#FFFFFF"></chart>"); getResponse().setContentType("application/xml"); getResponse().setCharacterEncoding("utf-8"); byte[] tjkjByte = wsdwFileContent.toString().getBytes("utf-8"); getResponse().getOutputStream().write(tjkjByte); } catch (IOException e) { e.printStackTrace(); } 最终页面怎么也无法生成图表,显示"Invalid XML Data"。 网上查找资料说是在生成XML文档前,必须插入BOM标记(Byte Order Mark),代码如下: try {
String beginYear = super.getParameter("beginYear");
String endYear = super.getParameter("endYear");
StringBuffer wsdwFileContent = new StringBuffer(getBom() + "<?xml version="1.0" encoding="UTF-8"?><chart caption="" + beginYear + "年至" + endYear + "年" baseFontSize="12" palette="2" bgColor="#99CCFF,#FFFFFF"></chart>");
getResponse().setContentType("application/xml");
getResponse().setCharacterEncoding("utf-8");
byte[] tjkjByte = wsdwFileContent.toString().getBytes("utf-8");
getResponse().getOutputStream().write(tjkjByte);
} catch (IOException e) {
e.printStackTrace();
}
getBom() 方法: public String getBom () { String bom = null; try { byte[] bomByte = new byte[]{ (byte) 0xef,(byte) 0xbb,(byte) 0xbf }; bom = new String(bomByte,"UTF-8"); } catch (UnsupportedEncodingException e) { e.printStackTrace(); } return bom; } (编辑:李大同) 【声明】本站内容均来自网络,其相关言论仅代表作者个人观点,不代表本站立场。若无意侵犯到您的权利,请及时与联系站长删除相关内容! |
