如何使用poi或任何其他API在word文档中插入框架

Question

如何使用Apache POI从我的Java代码中将框架插入word文件？

我希望框架（仅限左边框）插入页面的右上角。

您可以看到以红色框突出显示的框架：

您可以使用docx4j。使用docx4j处理docx文件更容易。 您可以查看：http://blog.iprofs.nl/2012/10/22/adding-images-and-layout-to-your-docx4j-generated-word-documents-part-1/

以下是代码：

public class AddingAnInlineImage {
/**
 *  As is usual, we create a package to contain the document.
 *  Then we create a file that contains the image we want to add to the document.
 *  In order to be able to do something with this image, we'll have to convert
 *  it to an array of bytes. Finally we add the image to the package
 *  and save the package.
 */
public static void main (String[] args) throws Exception {
    WordprocessingMLPackage  wordMLPackage =
        WordprocessingMLPackage.createPackage();

    File file = new File("src/main/resources/iProfsLogo.png");
    byte[] bytes = convertImageToByteArray(file);
    addImageToPackage(wordMLPackage, bytes);

    wordMLPackage.save(new java.io.File("src/main/files/HelloWord7.docx"));
}

/**
 *  Docx4j contains a utility method to create an image part from an array of
 *  bytes and then adds it to the given package. In order to be able to add this
 *  image to a paragraph, we have to convert it into an inline object. For this
 *  there is also a method, which takes a filename hint, an alt-text, two ids
 *  and an indication on whether it should be embedded or linked to.
 *  One id is for the drawing object non-visual properties of the document, and
 *  the second id is for the non visual drawing properties of the picture itself.
 *  Finally we add this inline object to the paragraph and the paragraph to the
 *  main document of the package.
 *
 *  @param wordMLPackage The package we want to add the image to
 *  @param bytes         The bytes of the image
 *  @throws Exception    Sadly the createImageInline method throws an Exception
 *                       (and not a more specific exception type)
