struts2整合jfreechart1.0.14 中文显示问题

zsq_kaka1 2012-05-01 01:07:42

由于毕业设计想用jfreechart1.0.14做报表统计，但是图片显示出来后中文无法正常显示，都变成了方框，而且我已经对字体进行了设置，求教各位网友....(在未整合struts2直接把java代码写在jsp文件中时能正常显示)
Action部分代码：



HttpServletRequest request=ServletActionContext.getRequest();

HttpSession session=request.getSession();

CategoryDataset dataset = DatasetUtilities.createCategoryDataset(rowKeys, columnKeys, data);

JFreeChart chart = ChartFactory.createBarChart3D(title,

        x,

        y,

        dataset,

        PlotOrientation.VERTICAL,

        true,

        true,

        false); 

CategoryPlot plot = chart.getCategoryPlot();



//设置字体，不然会中文乱码

Font font = new Font("宋体", Font.BOLD, 16); 

TextTitle title1 = new TextTitle(title, font);

chart.setTitle(title1); //标题

        

NumberAxis numberaxis = (NumberAxis) plot.getRangeAxis();

CategoryAxis domainAxis = plot.getDomainAxis();  

domainAxis.setTickLabelFont(new Font("sans-serif", Font.PLAIN, 11));     /*------设置X轴坐标上的文字-------*/ 

domainAxis.setLabelFont(new Font("宋体", Font.PLAIN, 12));       /*------设置X轴的标题文字------------*/  

numberaxis.setTickLabelFont(new Font("sans-serif", Font.PLAIN, 12)); /*------设置Y轴坐标上的文字-----------*/  

numberaxis.setLabelFont(new Font("黑体", Font.PLAIN, 12));      /*------设置Y轴的标题文字------------*/

chart.getLegend().setItemFont(new Font("宋体", Font.PLAIN, 12));
