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.xml3.新建servlet4.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[align=left]<!--begin exporter highcharts-->[/align][align=left]<servlet>[/align][align=left]<servlet-name>HighChartsServlet</servlet-name>[/align][align=left]<servlet-class>com.sinosoft.lis.highcharts.HighChartsServlet</servlet-class>[/align][align=left]<load-on-startup>10</load-on-startup>[/align][align=left]</servlet>[/align][align=left]<servlet-mapping>[/align][align=left]<servlet-name>HighChartsServlet</servlet-name>[/align][align=left]<url-pattern>/getHighchartServlet</url-pattern>[/align][align=left]</servlet-mapping>[/align][align=left]<!--over exporter highcharts-->[/align][align=left]3.sevlet代码如下[/align][align=left]packagecom.sinosoft.lis.highcharts;[/align][align=left]
