2. Code section

step ：

2. Processing images
3. Replace docx file
4. Write to hard disk

public class ReplaceDocx {
    
    //  Replace docx Information in the file 
    private File docxReplace(String wordPath)  {
    
        //  Text to be replaced 、 Picture writing map Collection 
        Map<String, Object> map = new HashMap<>();
        map.put("name", " Zhang San ");
        map.put("sex", " male ");
        map.put("address", " The Beijing municipal XX District XX road ");
        try {
    
            //  Image processing 
            PictureRenderData pictureRenderData = Pictures.ofStream(new FileInputStream("d:\\zhangsan.jpg"), PictureType.PNG)
                    .size(102, 126).create();
        } catch (FileNotFoundException e) {
    
            e.printStackTrace();
        }
        map.put("photo", pictureRenderData);

        //  The path to save the generated new file 
        File repotrFile = new File("D:\\new.docx");
        try {
    
        //  Create a new file and write it to the hard disk 
            XWPFTemplate.compile(wordPath).render(map, new FileOutputStream(repotrFile));
        } catch (IOException e) {
    
            e.printStackTrace();
        }
        // Todo
        //  You can perform other operations on files , for example ： Print , Delete the file after printing 
		// repotrFile.delete(); 
		//  Or just go back File
        return repotrFile;
    }

    public static void main(String[] args) {
    
        File file = new ReplaceDocx().docxReplace("D:\\old.docx");
    }
}

3. a key

1. map Types defined in the collection ：Map<String, Object> If there are pictures, you need to vlaue Value is defined as Object, If the replacement is all characters , Then it only needs to be defined as Map<String, String>
   1.1 Be careful map aggregate key Value , It only needs { {}} String in the , Methods used in other tutorials , May need to be signed .
2. Image processing ：Pictures.ofStream(new FileInputStream("d:\\zhangsan.jpg"), PictureType.PNG).size(102, 126).create()
   2.1 Pictures There are many ways to construct , This example is constructed by character stream , You can also use BufferedImage、base64、byte[] Isoparametric construction , See the source code for details .
   2.2 The second parameter is the image format created
   2.3 size() Method , Obviously, it is to specify the size of the generated image
   2.4 The most important point ： stay docx The name of the picture in the template file should be preceded by @
3. Replace the template file and write to the hard disk ： XWPFTemplate.compile(wordPath).render(map, new FileOutputStream(repotrFile));
