fusioncharts获取xml数据源路劲问题？
最近在研究fusioncharts报表，今天遇到一个问题很纠结,始终无法明确xml数据源的路径，忘高手指点:
后台:
public String showChart(){
try {
//获得数据集
List<SaleNum> list = this.saleNumService.getSaleNum();
Document document = DocumentHelper.createDocument();
document.setXMLEncoding("utf-8");
Element eGraph = document.addElement("graph");
eGraph.addAttribute("caption", "sale") ;
eGraph.addAttribute("xAxisName", "mon");
eGraph.addAttribute("yAxisName", "Units");
eGraph.addAttribute("showNames", "1") ;
eGraph.addAttribute("decimalPrecision", "0");
eGraph.addAttribute("formatNumberScale","0") ;
for(int i = 0;i < list.size(); i++){
Element eSet = eGraph.addElement("set");
eSet.addAttribute("label", list.get(i).getMonth());
eSet.addAttribute("value", list.get(i).getNum().toString());
eSet.addAttribute("color", "17400") ;
}
String path = Address.getAddress();//path是tomcat\webapps\项目名称
Writer out = new FileWriter(path+"\\data.xml");
OutputFormat format = OutputFormat.createPrettyPrint();
format.setEncoding("UTF-8");
XMLWriter writer = new XMLWriter(out,format);
writer.write(document);
writer.close();
System.out.println("xml生成成功");
} catch (Exception e) {
System.out.println("xml生成失败");
e.printStackTrace();
}
return "showChart";
}
前台:

String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
String path1 = System.getProperty("user.dir");
int num = path1.indexOf("\\bin");
String path2 = path1.substring(0,num);
out.println(path1+"\n");
out.println(path+"\n");
out.println(basePath);
out.println(path2);
String path3 = path2+"\\webapps\\ZZXJ2\\data.xml";
out.println(path3);
