Java+Aspose.diagram,导出数据到Visio

背景：java,家谱图导出，主要包括家庭成员图片以及有关系进行连线

项目环境请参考

或者是参考我关于Aspose相关的文章，自己搭建项目
业务代码如下：

DemoController

@GetMapping("/exportVisio")
    public void exportVisio(HttpServletRequest request, HttpServletResponse response){
        demoService.exportVisio(request, response);
    }

DemoService

void exportVisio(HttpServletRequest request, HttpServletResponse response);

DemoServiceImpl

@Override
    public void exportVisio(HttpServletRequest request, HttpServletResponse response) {
        try {
            // 去除水印和数量限制
            Resource resource = new ClassPathResource("license.xml");
            InputStream is = resource.getInputStream();
            License license= new License();
            license.setLicense(is);

            // 画图表
            Resource resource1 = new ClassPathResource("basic.vss");
            InputStream stream = resource1.getInputStream();
            Diagram diagram = new Diagram(stream);
            Page page0 = diagram.getPages().get(0);

            //插入图片
            double pinX = 2, pinY = 2, width = 4, hieght = 3;
            URL url = new URL("https://t7.baidu.com/it/u=3818512871,2061378298&fm=193&f=GIF");
            //打开链接
            HttpURLConnection conn = (HttpURLConnection)url.openConnection();
            //通过输入流获取图片数据
            InputStream inStream = conn.getInputStream();
            long one = page0.addShape(pinX, pinY, width, hieght,inStream );

			//这样写图片的边框会带有颜色，修改边框颜色为白色
			page0.getShapes().getShape(one).getLine().getLineColor().setValue("#FFFFFF");
			
			//在指定位置插入文本图形
			page0.addText(1, 1, 1, 1, "文本文本");
			
			//将所有的文本填充模式设置为不填充
			for (Shape shape : (Iterable<Shape>) page0.getShapes()) {
                if (shape.getText().getValue().getText() != ""){
                    shape.getFill().setFillPattern(new IntValue(0,0));
                }
            }

			//也可以在插入的图片上面增加文字
			page0.getShapes().getShape(one ).getText().getValue().add(new Cp(0));
            page0.getShapes().getShape(one ).getText().getValue()
            .add(new Txt("TextStyle_Regular\n"));



            //本地图片插入
            long two = page0.addShape(pinX, pinY, width, hieght, new FileInputStream("d:\\aa.png"));

            //连线
            Shape connector1 = new Shape();
            long connecter1Id = diagram.addShape(connector1, "Dynamic connector", 0);
            diagram.getPages().getPage(0).connectShapesViaConnector(two, ConnectionPointPlace.CENTER,
                    one, ConnectionPointPlace.CENTER, connecter1Id);

            //返回流数据到前端
            response.setContentType("application/octet-stream");
            response.setHeader("Content-disposition", "attachment;filename="
                    + "export.vsdx");
            OutputStream outputStream = new BufferedOutputStream(response.getOutputStream());
            DiagramSaveOptions options = new DiagramSaveOptions(SaveFileFormat.VSDX);
            options.setAutoFitPageToDrawingContent(true);
            diagram.save(outputStream, options);
            //强制将缓存区的数据进行输出
            outputStream.flush();
            //关流
            outputStream.close();
            conn.disconnect();
            inStream.close();
        } catch (Exception e){
            e.printStackTrace();
        }
    }
