如何使用Apache POI重写. xlsm文件？

Question

我使用这段代码使用ApachePOI重写xlsm文件。我必须从resultset重写Sheet1上的数据，这段代码创建模板xlsm文件的副本，并执行所有处理。

但当我打开创建的xlsm文件时，会显示以下消息：

我们发现“文件名”中的某些内容有问题。xlsm’。你想让我们尽力恢复吗？如果您信任此工作簿的来源，请单击“是”。

这是我的代码，请建议我该怎么做。

public void dbConnect(String driver_connect_string, String db_connect_string, String db_userid, String db_password){
  try{ 
    Class.forName(driver_connect_string);
    Connection conn = DriverManager.getConnection(db_connect_string, db_userid, db_password);
    System.out.println("connected");
    Statement statement = conn.createStatement();
    Properties propq = new Properties();    
    FileInputStream fisq = new FileInputStream("query.properties");
    propq.load(fisq);
    String queryString = propq.getProperty("myQueryString");
    ResultSet rs = statement.executeQuery(queryString);

    Properties propf2 = new Properties();   
    FileInputStream fisf2 = new FileInputStream("file.properties");
    propf2.load(fisf2);

    OPCPackage pkg = OPCPackage.open(new File(propf2.getProperty("sourceFile")));
    XSSFWorkbook wb_template;
    wb_template = new XSSFWorkbook(pkg);
    System.out.println("package loaded");
    SXSSFWorkbook wb = new SXSSFWorkbook(wb_template); 
    wb.setCompressTempFiles(true);

     Sheet  sheet = wb.getSheetAt(0); 
     Row rowhead = sheet.createRow((short) 0);
         rowhead.createCell((short) 0).setCellValue("EmpId");
         rowhead.createCell((short) 1).setCellValue("EmaName");
         rowhead.createCell((short) 2).setCellValue("Department");
         rowhead.createCell((short) 3).setCellValue("Job Title");
         rowhead.createCell((short) 4).setCellValue("DOB");
         int index = 1;
         while (rs.next()) {
              Row row = sheet.createRow((short) index);
              row.createCell((short) 0).setCellValue(rs.getString(1));
              row.createCell((short) 1).setCellValue(rs.getString(2));
              row.createCell((short) 2).setCellValue(rs.getString(3));
              row.createCell((short) 3).setCellValue(rs.getString(4));
              row.createCell((short) 4).setCellValue(rs.getString(5));
              index++;
          }


         FileOutputStream out = new FileOutputStream(new File(propf2.getProperty("destFile")));
         System.out.println("XLSM created Successfully");
         wb.write(out);
         out.close();  
    }catch(Exception e){
      e.printStackTrace();
  }
}

完成。。。。。。。

public void dbConnect(String driver_connect_string, String db_connect_string, String db_userid, String db_password){
 try{ 
  Class.forName(driver_connect_string);
  Connection conn = DriverManager.getConnection(db_connect_string, db_userid, db_password);
  System.out.println("connected");
  Statement statement = conn.createStatement();
  Properties propq = new Properties();    
  FileInputStream fisq = new FileInputStream("query.properties");
  propq.load(fisq);
  String queryString = propq.getProperty("myQueryString");
  ResultSet rs = statement.executeQuery(queryString);

  Properties propf2 = new Properties();   
  FileInputStream fisf2 = new FileInputStream("file.properties");
  propf2.load(fisf2);

  OPCPackage pkg = OPCPackage.open(new File(propf2.getProperty("sourceFile")));
  XSSFWorkbook wb_template;
  wb_template = new XSSFWorkbook(pkg);
  System.out.println("package loaded");


  Sheet  sheet = wb_template.getSheetAt(0);

  Row rowhead = sheet.createRow(0);
     rowhead.createCell(0).setCellValue("EmpId");
     rowhead.createCell(1).setCellValue("EmaName");
     rowhead.createCell(2).setCellValue("Department");
     rowhead.createCell(3).setCellValue("Job Title");
     rowhead.createCell(4).setCellValue("DOB");
     int index = 1;
     while (rs.next()) {
          Row row = sheet.createRow((short) index);
          row.createCell(0).setCellValue(rs.getString(1));
          row.createCell(1).setCellValue(rs.getString(2));
          row.createCell(2).setCellValue(rs.getString(3));
          row.createCell(3).setCellValue(rs.getString(4));
          row.createCell(4).setCellValue(rs.getString(5));
          index++;
      }


     FileOutputStream out = new FileOutputStream(new File(propf2.getProperty("destFile")));
     System.out.println("XLSM created Successfully");
     wb.write(out);
     out.close();  
  }catch(Exception e){
    e.printStackTrace();
  }
