该文是解决highchart导出中文乱码的笔记。

步骤：
1、下载jar包
我下了5个，网上说可以下载4个
2.修改web.xml
3.新建servlet
4.将highchats 的exporting属性的url修改为 自己建立的servlet
具体如下：
2.web.xml中增加如下代码
< servlet >
< servlet-name > HighChartsServlet servlet-name >
< servlet-class > com.sinosoft.lis.highcharts.HighChartsServlet servlet-class >
< load-on-startup > 10 load-on-startup >
servlet >
< servlet-mapping >
< servlet-name > HighChartsServlet servlet-name >
< url-pattern > /getHighchartServlet url-pattern >
servlet-mapping >
3.sevlet代码如下
package com.sinosoft.lis.highcharts;

import java.io.IOException;
import java.io.StringReader;

import javax.servlet.ServletException;
import javax.servlet.ServletOutputStream;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.apache.batik.transcoder.Transcoder;
import org.apache.batik.transcoder.TranscoderException;
import org.apache.batik.transcoder.TranscoderInput;
import org.apache.batik.transcoder.TranscoderOutput;
import org.apache.batik.transcoder.p_w_picpath.JPEGTranscoder;
import org.apache.batik.transcoder.p_w_picpath.PNGTranscoder;
import org.apache.fop.svg.PDFTranscoder;

/**
* Servlet implementation class for the batik Transcoder
* @author tangyujing

*/
public class HighChartsServlet extends HttpServlet {
private static final long serialVersionUID = 3920224595120519682L;
public HighChartsServlet() {
super ();
}

protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
doPost(request,response);
}
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException{
request.setCharacterEncoding( "utf-8" ); //注意编码
String type = request.getParameter( "type" );
String svg = request.getParameter( "svg" );
ServletOutputStream out = response.getOutputStream();
if ( null != type && null != svg){
// This line is necessary due to a bug in the highcharts SVG generator for IE
// I'm guessing it wont be needed later.
svg = svg.replaceAll( ":rect" , "rect" );
String ext = "" ;
Transcoder t = null ;
if (type.equals( "p_w_picpath/png" )) {
ext = "png" ;
t = new PNGTranscoder();
} else if (type.equals( "p_w_picpath/jpeg" )) {
ext = "jpg" ;
t = new JPEGTranscoder();

} else if (type.equals( "application/pdf" )) {
ext = "pdf" ;
t = new PDFTranscoder();

} else if (type.equals( "p_w_picpath/svg+xml" )) {
ext = "svg" ;
}
response.addHeader( "Content-Disposition" , "p_w_upload; filename=chart." +ext);
response.addHeader( "Content-Type" , type);
if ( null != t){
TranscoderInput input = new TranscoderInput( new StringReader(svg));
TranscoderOutput output = new TranscoderOutput(out);
try {
t.transcode(input,output);
} catch (TranscoderException e){
out.print( "Problem transcoding stream. See the web logs for more details." );
e.printStackTrace();
}
} else if (ext == "svg" ){
out.print(svg);
} else {
out.print( "Invalid type: " + type);
}
} else {
response.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." );
}
out.flush();
out.close();
}
}
4. jsp中highchs的导出功能
//增加导出功能
exporting: {
enabled: true ,
///url:getRootPath()+"/getHighchartServlet",
url: 'http://localhost:8080/xiangmuming/getHighchartServlet' ,
filename: 'chart' ,
width:800,
type: 'p_w_picpath/png'
},


或者采用（这是设置时间方法，下载pdf）

chart.exportChart({
url: 'http://localhost:8080/hr821/getHighchartServlet' ,
type: 'application/pdf' ,
filename: 'fff'
}); //导出pdf
