java使用poi-tl模版引擎导出word之饼状图生成及循环批量生成饼状图

一、单个饼状图生成

1.word模版制作

在word中创建一个饼状图，点击图表，点击“文本选项”，在可选文字标题中填入{{pieChart}}

2.编写接口完整代码

    @GetMapping("/exportWord")public void exportWord(HttpServletResponse response) throws FileNotFoundException {//存放数据，也就是填充在word里面的值Map<String, Object> params = new HashMap<>();params.put("title","测试使用poi-tl模版导出word");ChartSingleSeriesRenderData pie = Charts.ofSingleSeries("测试第一个饼图", new String[] { "男", "女" }).series("countries", new Integer[] { 9826675, 9596961 }).create();params.put("pieChart", pie);// 或模板在静态资源的相对路径File rootFile = new File((ResourceUtils.getURL("classpath:").getPath()));File templateFile = new File(rootFile, "/static/templates/exportWord.docx");//jar包获取不到文件路径`//URLDecoder.decode() 解决获取中文名称文件路径乱码String templatePath = URLDecoder.decode(templateFile.getPath());//生成文件名String fileName = new SimpleDateFormat("yyyyMMddHHmmss").format(new Date()) + "_" + System.currentTimeMillis();// 导出woldtry {// 导出Word文档为文件XWPFTemplate template = XWPFTemplate.compile(templatePath,builder.build()).render(params);// 将导出的Word文件转换为流response.setContentType("application/octet-stream");response.setHeader("Content-disposition","attachment;filename=\""+fileName+".docx"+"\"");// HttpServletResponse responseOutputStream out = response.getOutputStream();BufferedOutputStream bos = new BufferedOutputStream(out);template.write(bos);bos.flush();out.flush();// 最后不要忘记关闭这些流。PoitlIOUtils.closeQuietlyMulti(template, bos, out);} catch (Exception e) {System.out.println("导出Word文档时出现异常：" + e.getMessage());}}

3.导出结果

二、批量生成饼图

1.word模版制作

在word中创建一个饼状图，点击图表，点击“文本选项”，在可选文字标题中同样填入{{pieChart}}

2.编写接口完整代码

    @GetMapping("/exportWord")public void exportWord(HttpServletResponse response) throws FileNotFoundException {//存放数据，也就是填充在word里面的值Map<String, Object> params = new HashMap<>();params.put("title","测试使用poi-tl模版导出word");List<Map<String, Object>> list = new ArrayList<>();Map<String, Object> map = new HashMap<>();map.put("a","测试");map.put("b","米");map.put("c","201312");ChartSingleSeriesRenderData pie = Charts.ofSingleSeries("测试第一个饼图", new String[] { "男", "女" }).series("countries", new Integer[] { 9826675, 9596961 }).create();map.put("pieChart", pie);list.add(map);Map<String, Object> map1 = new HashMap<>();map1.put("a","测试2");map1.put("b","千米");map1.put("c","2012312");ChartSingleSeriesRenderData pie1 = Charts.ofSingleSeries("测试第二个饼图", new String[] { "上海", "广州" }).series("countries", new Integer[] { 253, 985 }).create();map1.put("pieChart", pie1);list.add(map1);params.put("list",list);// 或模板在静态资源的相对路径File rootFile = new File((ResourceUtils.getURL("classpath:").getPath()));File templateFile = new File(rootFile, "/static/templates/exportWord.docx");//jar包获取不到文件路径`//URLDecoder.decode() 解决获取中文名称文件路径乱码String templatePath = URLDecoder.decode(templateFile.getPath());//生成文件名String fileName = new SimpleDateFormat("yyyyMMddHHmmss").format(new Date()) + "_" + System.currentTimeMillis();// 导出woldtry {// 导出Word文档为文件XWPFTemplate template = XWPFTemplate.compile(templatePath,builder.build()).render(params);// 将导出的Word文件转换为流response.setContentType("application/octet-stream");response.setHeader("Content-disposition","attachment;filename=\""+fileName+".docx"+"\"");// HttpServletResponse responseOutputStream out = response.getOutputStream();BufferedOutputStream bos = new BufferedOutputStream(out);template.write(bos);bos.flush();out.flush();// 最后不要忘记关闭这些流。PoitlIOUtils.closeQuietlyMulti(template, bos, out);} catch (Exception e) {System.out.println("导出Word文档时出现异常：" + e.getMessage());}}
