web.xml中配置下serlvet：
<!--begin?exporter?highcharts-->
<servlet>
<servlet-name>HighChartsServlet</servlet-name>
<servlet-class>com.friendone.mrms.ws.material.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>
<!--over?exporter?highcharts-->
然后修改highcharts的exporting.js：
url:?'http://export.highcharts.com/'改为本地的servlet地址
url:"http://localhost:8080/cmrm/getHighchartServlet"
这就可以本地导出图片了，在servlet里可以自己设置编码消除中文乱码。??
