要实现基于Java合并doc和docx格式的Word文件,可以考虑使用Apache POI库来操作Word文件。下面是一个简单的示例代码,可以将多个docx文件合并为一个:
```java
import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import java.util.ArrayList;
import java.util.List;
import org.apache.poi.xwpf.usermodel.*;
public class MergeWordFiles {
public static void main(String[] args) throws IOException {
String[] filesToMerge = {"file1.docx", "file2.docx", "file3.docx"};
String mergedFileName = "merged.docx";
List<XWPFDocument> files = new ArrayList<>();
for (String fileName : filesToMerge) {
XWPFDocument document = new XWPFDocument(OPCPackage.open(fileName));
files.add(document);
}
XWPFDocument mergedDocument = mergeDocuments(files);
FileOutputStream outputStream = new FileOutputStream(new File(mergedFileName));
mergedDocument.write(outputStream);
outputStream.close();
}
private static XWPFDocument mergeDocuments(List<XWPFDocument> files) {
XWPFDocument mergedDocument = new XWPFDocument();
XWPFParagraph newParagraph;
for (XWPFDocument document : files) {
for (XWPFParagraph paragraph : document.getParagraphs()) {
newParagraph = mergedDocument.createParagraph();
newParagraph.setAlignment(paragraph.getAlignment());
for (XWPFRun run : paragraph.getRuns()) {
newParagraph.createRun().setText(run.getText(0));
}
}
for (XWPFTable table : document.getTables()) {
mergedDocument.createTable().addNewCol();
mergedDocument.createTable().addNewRow();
for (XWPFTableRow row : table.getRows()) {
XWPFTableRow newRow = mergedDocument.createTable().getRow(0);
newRow.setHeight(row.getHeight());
for (XWPFTableCell cell : row.getTableCells()) {
XWPFTableCell newCell = newRow.addNewTableCell();
newCell.setVerticalAlignment(cell.getVerticalAlignment());
newCell.setAlignment(cell.getAlignment());
newCell.setText(cell.getText());
}
}
}
}
return mergedDocument;
}
}
```
这个示例代码中,先将要合并的docx文件读取为XWPFDocument对象,然后将所有文件合并到一个新的XWPFDocument对象中,最后将合并后的XWPFDocument对象写入到一个新的docx文件中。
需要注意的是,这个示例代码只能合并docx格式的Word文件,如果需要合并doc格式的Word文件,需要使用HWPF库进行操作。同时,如果要处理较大的Word文件,可能需要考虑分段处理,以避免内存溢出等问题。
