Apache POI是一个用于读写Microsoft Office格式文档的Java库,包括Excel、Word和PowerPoint等。使用POI可以通过模板生成Word文档,具体步骤如下:
1. 创建一个空的Word文档
```
XWPFDocument doc = new XWPFDocument();
```
2. 打开模板文件
```
InputStream is = new FileInputStream("template.docx");
XWPFDocument template = new XWPFDocument(is);
```
3. 获取模板中的段落和表格
```
List<XWPFParagraph> paragraphs = template.getParagraphs();
List<XWPFTable> tables = template.getTables();
```
4. 遍历段落和表格,替换占位符
```
for (XWPFParagraph paragraph : paragraphs) {
String text = paragraph.getText();
if (text.contains("{{name}}")) {
text = text.replace("{{name}}", "Tom");
paragraph.setText(text);
}
}
for (XWPFTable table : tables) {
List<XWPFTableRow> rows = table.getRows();
for (XWPFTableRow row : rows) {
List<XWPFTableCell> cells = row.getTableCells();
for (XWPFTableCell cell : cells) {
String text = cell.getText();
if (text.contains("{{age}}")) {
text = text.replace("{{age}}", "25");
cell.setText(text);
}
}
}
}
```
5. 将生成的内容写入到新的Word文档中
```
FileOutputStream fos = new FileOutputStream("output.docx");
doc.write(fos);
fos.close();
```
这样就可以使用POI通过模板生成Word文档了。需要注意的是,模板中的占位符需要与代码中的占位符一致,否则替换不成功。
