eastwood中文显示乱码问题的解决办法

eastwood是google图表api的开源的独立的实现，基于jfreechart。eastwood使得调用jfreechart不用再深入到什么plot、Axis、Renderer的细节中去，用更简单优雅的方式画图。

默认配置的eastwood会有中文乱码问题，解决方法如下：

将jfreechart升级到1.0.10，eastwood升级到1.1.0，然后在web.xml里面配置

  <servlet>
    <servlet-name>chart</servlet-name>
    <servlet-class>org.jfree.eastwood.ChartServlet</servlet-class>
    <init-param>
      <param-name>fontResource</param-name>
      <param-value>/WEB-INF/classes/wqy-zenhei.ttc</param-value>
    </init-param>
  </servlet>
  <servlet-mapping>
    <servlet-name>chart</servlet-name>
    <url-pattern>/chart</url-pattern>
  </servlet-mapping>

这里的wqy-zenhei.ttc可以是任何一种支持中文的字体文件，我用文泉驿。

如果是用tomcat，要在它的server.xml里面处理get中文乱码问题。

对于firefox，这样配置已经没有中文乱码问题了，但是对于ie，对中文要这样编码

URLEncoder.encode("费用","utf-8")

ps,eastwood已1年多没有发布新版本，有人就去问项目是否停止了，jfreechart开发者的回答让人心酸。一个著名的开源项目开发者还要为生计奔波。

It isn't discontinued, just very quiet. There's only been limited interest in the project, and for financial reasons I have had to focus my energies on tasks that generate some income rather than just creating more free stuff. I committed some stuff to Subversion last month, and would like to make a new release of Eastwood some time...but I have another project on right now.
