第二步 制作word模板
图片的循环这里使用[@xxxx]占位，普通文本字段使用{{xxxx}}占位，因为存在行复制，所以使用{{xxx}}占位后，使用[xxxx]进行占位
第三步 直接上代码
a.因为涉及到对于图片的处理，图片也要进行行循环，所以要继承AbstractRenderPolicy，话不多数，直接上代码
public class PictureRenderPolicy extends AbstractRenderPolicy<List<PictureRenderData>> {
@Override
public void doRender(RenderContext<List<PictureRenderData>> renderContext) throws Exception {
WhereDelegate where = renderContext.getWhereDelegate();
List<PictureRenderData> data = renderContext.getData();
for (int i = 0; i < data.size(); i++) {
// 目标宽度,等比例缩放图片，指定宽度
int targetWidth = 200;
ByteArrayInputStream in = new ByteArrayInputStream(data.get(i).getPictureSupplier().get());
BufferedImage image = ImageIO.read(in);
int originalWidth = image.getWidth();
int originalHeight = image.getHeight();
int targetHeight = (int) Math.round((double) targetWidth / originalWidth * originalHeight);
//缩放图片
BufferedImage scaledImage = new BufferedImage(targetWidth, targetHeight, BufferedImage.TYPE_INT_RGB);
Graphics2D graphics2D = scaledImage.createGraphics();
graphics2D.drawImage(image.getScaledInstance(targetWidth, targetHeight, Image.SCALE_SMOOTH), 0, 0, null);
graphics2D.dispose();
byte[] scaledImageData = getImageBytes(scaledImage);
where.addPicture(new ByteArrayInputStream(scaledImageData),6,targetWidth,targetHeight);
}
}
@Override
protected void afterRender(RenderContext<List<PictureRenderData>> context) {
// 清空标签
clearPlaceholder(context, true);
}
}
private static byte[] getImageBytes(BufferedImage image) throws Exception {
File tempFile = File.createTempFile("tempImage", "");
ImageIO.write(image, "png", tempFile);
FileInputStream inputStream = new FileInputStream(tempFile);
byte[] imageData = IOUtils.toByteArray(inputStream);
inputStream.close();
tempFile.delete();
return imageData;
}
最后进行测试
@Test
public void test5(){
//创建行循环策略
LoopRowTableRenderPolicy rowTableRenderPolicy = new LoopRowTableRenderPolicy();
//告诉模板引擎，要在p做行循环,绑定行循环策略
Configure configure = Configure.builder().bind("p", rowTableRenderPolicy).bind("c",rowTableRenderPolicy).bind("img", new PictureRenderPolicy()).bind("img1", new PictureRenderPolicy()).build();
//创建目标文件
File sourceFile = new File("D:\\company\\develop\\pdfdemo\\src\\main\\resources\\templates\\temp.docx");
//构建数据
Map<String, Object> data = new HashMap();
data.put("projectName", "jiefei");
data.put("date", "18");
data.put("person1", "福建福清");
data.put("person2", "福建福清");
