Spire.Cloud.Word provides the mergeApi interface for developers to merge Word documents, and this tutorial will demonstrate how to do it.

import spire.cloud.word.sdk.client.*;
import spire.cloud.word.sdk.client.api.MergeApi;
import spire.cloud.word.sdk.client.model.MergingFile;
import java.util.*;

public class MergeWordDocuments {
    static String appId = "App ID";
    static String appKey = "App Key";
    static String baseUrl = " https://api.cloudxdocs.com ";

    //Create a Configuration object based on your AppID and AppKey
    static Configuration wordConfiguration = new Configuration(appId, appKey, baseUrl);
    //Create a mergeApi instance
    static MergeApi mergeApi = new MergeApi(wordConfiguration);

    public static void main(String[] args) throws ApiException{
        //Load the first sample document
        String name = "Sample1.docx";
        //Load the second sample document and add it into List
        List files = new ArrayList();
        files.add(new MergingFile("input/Sample2.docx",null,null));

        //Specify the folder storing the first sample. It’s null if nothing
        String folder = "input";
        //Specify password of the first sample. It’s null if nothing
        String password = null;
//Use the 2G storage provided by E-iceblue. It's null by default
        String storage = null;
        //Save the resulting document to a specified path
        String destFilePath = "output/mergeDocument.docx";

        //Call the mergeDocument method to merge Word documents
        mergeApi.mergeDocument(name, files, destFilePath, folder, storage, password);
    }
}
