1. 引入maven依赖

	<repositories>
        <repository>
            <id>com.e-iceblue</id>
            <name>e-iceblue</name>
            <url>https://repo.e-iceblue.cn/repository/maven-public/</url>
        </repository>
    </repositories>

	<dependency>
	    <groupId>e-iceblue</groupId>
	    <artifactId>spire.doc.free</artifactId>
	    <version>5.2.0</version>
	</dependency>

2. 需要合并的word

3. 合并文档代码

package com.spire.demo;


import com.spire.doc.Document;
import com.spire.doc.FileFormat;

public class MergeDocDemo {

    public static void main(String[] args) {
        String file1 = "D:\\poiword\\wd\\hb\\测试合并文档1.docx";
        String file2 = "D:\\poiword\\wd\\hb\\测试合并文档2.docx";
        String file3 = "D:\\poiword\\wd\\hb\\测试合并文档3.docx";

        String mergeFilePath = "D:\\poiword\\wd\\hb\\合并文档.docx";

        Document document = new Document(file1);
        //将文档file2内容完全插入到文档file1
        document.insertTextFromFile(file2, FileFormat.Docx_2013);

        //将文档file3内容完全插入到文档file1
        document.insertTextFromFile(file3, FileFormat.Docx_2013);


        //合并后的文档保存到mergeFilePath
        document.saveToFile(mergeFilePath, FileFormat.Docx_2013);
    }
}
