jfreechart中map在jsp页面显示
最近学习了Jfreechart发现资料有点少，找了好久都没有找到Map在jsp显示的详细资料所以记录一下，供大家学习：、Action代码：前面的不用多说，从这里开始：//map 的名字String filename = ServletUtilities.saveChartAsPNG(chart, 1030, 520, info, request.getSession());//这里的file其实就是map的字符串String file = ImageMapUtilities.getImageMap(filename, info, toolTipTagFragmentGenerator,new StandardURLTagFragmentGenerator());String graphURL = request.getContextPath() + "/DisplayChart?filename=" + filename;request.setAttribute("file", file);request.setAttribute("filename", filename);request.setAttribute("graphURL", graphURL);配置文件代码：<servlet> <servlet-name>DisplayChart</servlet-name> <servlet-class>org.jfree.chart.servlet.DisplayChart</servlet-class> </servlet><servlet-mapping> <servlet-name>DisplayChart</servlet-name> <url-pattern>/DisplayChart</url-pattern> </servlet-mapping> Jsp页面代码：<body> ${file } <img src="${graphURL }" border=0 usemap="#${filename }"></body>这样就好了。?
