使用Apache POI生成word写入到浏览器的代码怎么写

以下是使用Apache POI生成word写入到浏览器的Java代码示例：

import java.io.ByteArrayOutputStream;
import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.ServletOutputStream;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.poi.xwpf.usermodel.XWPFDocument;

public class WriteWordServlet extends HttpServlet {
    protected void doGet(HttpServletRequest request, HttpServletResponse response)
            throws ServletException, IOException {
        response.setContentType("application/msword");
        response.setHeader("Content-Disposition", "attachment;filename=example.docx");
        ServletOutputStream ouputStream = response.getOutputStream();
        try {
            XWPFDocument doc = new XWPFDocument();
            // 在这里添加word文档的内容
            // ......
            ByteArrayOutputStream baos = new ByteArrayOutputStream();
            doc.write(baos);
            byte[] outByteStream = baos.toByteArray();
            response.setContentLength(outByteStream.length);
            ouputStream.write(outByteStream, 0, outByteStream.length);
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            ouputStream.flush();
            ouputStream.close();
        }
    }
}

你可以根据自己的需求对这个示例进行修改。
