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wold
        try {
            // 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 response
            OutputStream 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());
        }
    }

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wold
        try {
            // 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 response
            OutputStream 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());
        }
    }
