先要在exporting.js中修改导出图片的url是本地的服务器地址
String type = getPara("type");//getRequest().getParameter("type");
String svg =getPara("svg");// getRequest().getParameter("svg");
String filename = getPara("filename");//getRequest().getParameter("filename");
ServletOutputStream out1 = null;
try {
//getRequest().setCharacterEncoding("utf-8");
System.out.println(type);
System.out.println(svg);
System.out.println(filename);
filename = filename==null?"chart":filename;
out1 = getResponse().getOutputStream();
if (null != type && null != svg) {
svg = svg.replaceAll(":rect", "rect");
String ext = "";
Transcoder t = null;
if (type.equals("image/png")) {
ext = "png";
t = new PNGTranscoder();
} else if (type.equals("image/jpeg")) {
ext = "jpg";
t = new JPEGTranscoder();
} else if(type.equals("image/svg+xml")) {
ext = "svg";
}else if(type.equals("application/pdf")){
t = new PDFTranscoder();
ext = "pdf";
}
getResponse().addHeader("Content-Disposition", "attachment; filename="+ filename + "."+ext);
getResponse().addHeader("Content-Type", type);
if (null != t) {
TranscoderInput input = new TranscoderInput(new StringReader(svg));
TranscoderOutput output = new TranscoderOutput(out1);
try {
t.transcode(input, output);
} catch (TranscoderException e) {
out1.print("Problem transcoding stream. See the web logs for more details.");
e.printStackTrace();
}
} else if (ext.equals("svg")) {
// out.print(svg);
OutputStreamWriter writer = new OutputStreamWriter(out1, "UTF-8");
writer.append(svg);
writer.flush();
writer.close();
} /*else
out.print("Invalid type: " + type);*/
} else {
//getResponse().addHeader("Content-Type", "text/html");
// out.println("Usage:\n\tParameter [svg]: The DOM Element to be converted." +
// "\n\tParameter [type]: The destination MIME type for the elment to be transcoded.");
}
} catch (Exception e) {
e.printStackTrace();
}finally{
try {
out1.flush();
getResponse().flushBuffer();
out1.close();
} catch (Exception e2) {
}
}
需要的jar包：
