猜你需要:
在jsp中使用Highchart的步骤:
第一步:引入highchart必需的js文件
<! -- jquery的js要在引入highchart插件的js之前引入 --> <script src="<%=basePath%>js/Highcharts3.0.8/jquery-1.8.3.js"> </script> <!-- 实现highchart核心功能的js --> <script src="<%=basePath%>js/Highcharts3.0.8/highcharts.js"> </script> <!-- 导出和打印相关的js ,因为这里修改过的exporting.js包含中文,使用 charset="UTF-8" 进行指定 --> <script src="<%=basePath%>js/Highcharts3.0.8/exporting.js" charset="UTF-8"> </script>
开发过程遇到的问题:
1) Js的引入顺序错了,导致highchart的图表出不来,
Highchart插件中用到了jquery,当时jquery-1.8.3.js的引入顺序放到了highchart插件js的下面,
导致当加载highchart插件用到的js时,找不到jquery的js,报出某个js的函数不合法
因此 jquery的js要在引入highchart的js之前引入
2) exporting.js 打印下载的js中,提示的都是英文,
要显示中文,这里采用的方法是修改exporting.js
p(s.lang,{printChart:"打印报表",downloadPNG:"下载为PNG格式图片",downloadJPEG:"下载为JPEG格式图片",
downloadPDF:"下载为PDF格式文档",downloadSVG:"下载为SVG格式矢量图片",contextButtonTitle:"打印 下载"});
修改后的效果:
当修改了exporting.js后,当保存时,没法保存js,提示编码问题
解决方法是:
window>>preferences>>general>>content types
在右边的窗口中打开列表,选中"JavaScript",在下面的"default encoding"右边的输入框中输入"utf-8",再点"update"按钮
单击打印下载时,显示的下拉框在大部分的ie浏览器中显示的很难看,火狐下正常
原因: 上面的下拉框显示很长,是由于hr标签的原因,导致hr的宽度按照 100%进行了显示
解决方法:
在显示highchart图标的jsp页面中,添加hr的样式
<style>
hr{height: 0;margin: 0;padding: 0;width: 0;}
</style>
第二步:组装添加显示highchart图表所用的数据
显示highchart图标的js代码 $(function () { //填充数据使用,使用jquery来获取隐藏域的值 var xAxisTimeInfo = $("#xAxisTime").val(); var totalRecordInfo = $("#totalRecord").val(); var totalRecordHYInfo = $("#totalRecordHY").val(); var totalRecordLJInfo = $("#totalRecordLJ").val(); $('#container').highcharts({ chart: { type: 'spline' }, title: { text: '每月订单数量统计' }, subtitle: { text: '' }, exporting:{ filename:"订单统计", //下载显示的文件名称 sourceWidth: 1000, //下载图片的宽度 sourceHeight: 550, //下载图片的高度 //指定下载图片的url,这里使用的本地的java代码,没有使用官网的代码(那//样会受到highchart官网的网络限制,这里的java代码是结合的struts1来//实现的,在java代码解决了导出图片中中文乱码的问题以及下载文件名乱码//的问题,详见java代码中说明) url:'<%=basePath%>shop/newOrder/orderPre/exportImage.do'//这里是一个重点哦,也可以修改exporting.js中对应的url }, /** * 去掉图标的右下角HightCharts.com 的图标 */ credits: { enabled : false, //设置false就不会显示右下角的官网链接 //右下角连接的显示位置 position:{ align: 'right',x: -8, verticalAlign: 'bottom',y: -390 }, //右下角链接的地址href:'<%=basePath%>shop/newOrder/orderPre/orderSearch4HighCharts.do?type=1', text:'区域图表',//右下角连接的名字 style : {cursor:'pointer',color:'#909090',fontSize:'20px'} }, xAxis: { categories: }, yAxis: { min: 0, title: { text: '单位 (个)' } }, //鼠标旁边的提示框的样式 //1. point.y:.0f 提示框中显示的y轴单位的小数点位数 //2. style="width:160px;height:50px" 提示框的宽高 //3. point.key 坐标的x轴的值 tooltip: { headerFormat: '<span style="font-size:20px;">{point.key}</span><table style="width:160px;height:50px">', pointFormat: '<tr><td style="color:{series.color};padding:0">{series.name}: </td>' + '<td style="padding:0"><b>{point.y:.0f} </b></td></tr>', footerFormat: '</table>', shared: true, useHTML: true }, plotOptions: { column: { pointPadding: 0.2, borderWidth: 0 } }, //图例的显示名称和数据 //这里使用了eval函数处理一下,使用jquery获取到的隐藏域的值 //否则不会显示 series: [{ name: '裸机数量', data: }, { name: '订单总量', data: }, { name: '合约机数量', data: }] }); });
基本的highchart显示的数据格式是:
X轴数据信息
图例和显示数据的格式:
因此我们要做的就是根据需求,在java后台组装好上面的数据,填充到highchart的js代码中即可
导出的Java后台代码 (使用的是struts1)没有在struts的配置文件中配置,直接是在jsp中url请求
struts1版的结合highchart导出图片的java代码
使用highchart调用本地的java类导出图片时,用到的jar包
batik-all-1.6.jar fop.jar xerces-2.9.0.jar
/** * 配合highchart插件导出图片 * @param mapping * @param form * @param request * @param response * @return * @throws Exception */ public ActionForward exportImage (ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response) throws Exception { log.info("图片导出................"); request.setCharacterEncoding("gb2312");//设置编码,解决乱码问题 String type = request.getParameter("type"); String svg = request.getParameter("svg"); response.setCharacterEncoding("gb2312");//设置编码,解决乱码问题 String filename = request.getParameter("filename"); filename = filename==null?"chart":filename; ServletOutputStream out = response.getOutputStream(); log.info("type :"+type+" filename:"+filename); if (null != type && null != svg) { svg = svg.replaceAll(":rect", "rect"); String ext = ""; Transcoder t = null; if (type.equals("image/png")) { ext = "png"; t = new PNGTranscoder(); } else if (type.equals("image/jpeg")) { ext = "jpg"; t = new JPEGTranscoder(); }else if (type.equals("application/pdf")) { ext = "pdf"; t =(Transcoder) new PDFTranscoder(); }else if(type.equals("image/svg+xml")) ext = "svg"; //解决下载文件的文件名的乱码 response.addHeader("Content-Disposition", "attachment; filename="+ new String (filename.getBytes("gb2312"),"iso-8859-1") + "."+ext); response.addHeader("Content-Type", type); if (null != t) { TranscoderInput input = new TranscoderInput(new StringReader(svg)); TranscoderOutput output = new TranscoderOutput(out); try { t.transcode(input, output); } catch (TranscoderException e) { out.print("Problem transcoding stream. See the web logs for more details."); e.printStackTrace(); } } else if (ext.equals("svg")) { OutputStreamWriter writer = new OutputStreamWriter(out, "UTF-8"); writer.append(svg); writer.close(); } else out.print("Invalid type: " + type); } else { response.addHeader("Content-Type", "text/html"); out.println("Usage:\n\tParameter [svg]: The DOM Element to be converted." + "\n\tParameter [type]: The destination MIME type for the elment to be transcoded."); } out.flush(); out.close(); return null; }
使用highchart生成报表信息的部分后台java代码
开发中遇到的问题
java代码片段
Dao层的代码片段,查询数据封装成map,然后把map数据放到List中,然后在把list放到map中,调用json-lib插件转换成json数据 List ltHY = findSQL(dto, sqlHY.toString(), list.toArray()); List adminSqlTotalHY = new ArrayList(); //使用的LinkedHashMap,放到map中的数据使用顺序的 Map<String ,String> totalRecordHYMap = new LinkedHashMap<String ,String>(); for (int i = 0; ltHY!=null && i < ltHY.size(); i++) { Object[] obj = (Object[]) ltHY.get(i); totalRecordHYMap.put(obj[0]!=null?String.valueOf(obj[0]):"" ,obj[1]!=null? String.valueOf(obj[1]):""); } adminSqlTotalHY.add(totalRecordHYMap); //保存到map中 Map recordInfo = new LinkedHashMap(); recordInfo.put("Record_total", adminSqlTotalList); recordInfo.put("Record_LJ", adminSqlTotalLJ); recordInfo.put("Record_HY", adminSqlTotalHY); //把map数据转化为json数据 JSONObject jsonObjectFromMap =JSONObject.fromObject(recordInfo); dto.setAddress(jsonObjectFromMap.toString());
