java使用Jacob合并word

文件解压后是这样：

1、需要将jacob*.dll文件复制到jre的bin目录下，类似：D:\Program Files\Java\jre1.8.0_144\bin

2、将jacob.jar文件复制到lib并添加依赖

 

代码：

import java.io.File;
import java.util.ArrayList;
import java.util.List;

import com.jacob.activeX.ActiveXComponent;
import com.jacob.com.Dispatch;
import com.jacob.com.Variant;

public class WordMerge {

	/**
	 * @param fileList
	 *            合并多个word文档内容
	 * @param savepaths
	 *            合并保存新文档
	 */
	public static void mergeWordDataDoc(List<String> fileList, String savepaths) {
		if (fileList.size() == 0 || fileList == null) {
			return;
		}
		// 判断文件是否存在
		if (new File(savepaths).exists()) {
			try {
				new File(savepaths).createNewFile();
			} catch (Exception e) {
				e.printStackTrace();
			}
		} else {
			try {
				new File(savepaths).delete();
			} catch (Exception e) {
				e.printStackTrace();
			}
		}
		// 打开word
		ActiveXComponent app = new ActiveXComponent("Word.Application");
		try {
			// 设置word不可见
			app.setProperty("Visible", new Variant(false));
			// 获得documents对象
			Object docs = app.getProperty("Documents").toDispatch();
			// 打开第一个文件
			Object doc = Dispatch
					.invoke((Dispatch) docs,
							"Open",
							Dispatch.Method,
							new Object[] { (String) fileList.get(0),
									new Variant(false), new Variant(true) },
							new int[3]).toDispatch();
			// 追加文件
			for (int i = 1; i < fileList.size(); i++) {
				Dispatch.invoke(app.getProperty("Selection").toDispatch(),
						"insertFile", Dispatch.Method, new Object[] {
								(String) fileList.get(i), "",
								new Variant(false), new Variant(false),
								new Variant(false) }, new int[3]);
			}
			// 保存新的word文件
			Dispatch.invoke((Dispatch) doc, "SaveAs", Dispatch.Method,
					new Object[] { savepaths, new Variant(1) }, new int[3]);
			Variant f = new Variant(false);
			Dispatch.call((Dispatch) doc, "Close", f);
		} catch (Exception e) {
			throw new RuntimeException("合并word文件出错.原因:" + e);
		} finally {
			app.invoke("Quit", new Variant[] {});
		}
	}

	public static void main(String[] args) {
		//1、手打word列表
		List<String> filePathList = new ArrayList<>();
		filePathList.add("d:\\test\\1.doc");
		filePathList.add("d:\\test\\2.doc");
		filePathList.add("d:\\test\\3.doc");
		filePathList.add("d:\\test\\4.doc");
		mergeWordDataDoc(filePathList, "d:\\merge.doc");
		
		
		//2、自动读取目录下word
		String path = "d:\\test";
		File file = new File(path);
		File[] files = file.listFiles();
		List<String> list = new ArrayList<>();
		for (File f : files) {
			list.add(f.getAbsolutePath());
		}
		mergeWordDataDoc(list,"d:\\test\\merge.doc");
		System.out.println("success");

	}

}

可以手打word路径列表，也可以读取整个目录。
