                XWPFDocument document = new MyXWPFDocument(cpr.getInputStream());

                byte[] chartBytes = GenerateChartUtil.createPieChart("各级占比情况", legendNameList, dataList
                        , 300, 400, JFreeChartUtil.createChartTheme("宋体"));
                //将饼图数据变成图片

                WordExportUtil.exportWord07(document, contentMap);

                response.setHeader("content-type", "application/octet-stream");

### 3 模板文件 ###

模板路径：

模板内容：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM4OTc0NjM4_size_16_color_FFFFFF_t_70 1][]

###  注： ###

（1）模板中的替换标记必须以\{ \{开始，以\}\}结尾，同时替换标记最好先在记事本中输入好，在复制到Word文档中，否则会出现内容替换失败的情况。

（2）GenerateChartUtil、JFreeChartUtil的源码请查看以下博客。
