限制和 API 差异

公共 API 差异

以下列表(含示例代码段)展示了Aspose.Cells for Java和Aspose.Cells for Node.js via Java API之间的一些差异。

导入库（包比较）

Aspose.Cells for Java

 import com.aspose.cells.*;

Aspose.Cells for Node.js via Java

 var aspose = aspose || {};

aspose.cells = require("aspose.cells");

实例化新工作簿

Aspose.Cells for Java

 Workbook excelbook = new Workbook();

Aspose.Cells for Node.js via Java

 var excelbook = new aspose.cells.Workbook();

枚举或常量

Aspose.Cells for Java

 arc2.getLineFormat().setDashStyle(MsoLineDashStyle.SOLID);

Aspose.Cells for Node.js via Java

 arc2.getLineFormat().setDashStyle(aspose.cells.MsoLineDashStyle.SOLID);

流式文件

Aspose.Cells for Java

 InputStream inputstream = new FileInputStream(“Book1.xlsx”);

Workbook workbook = new Workbook(inputstream);

workbook.save(“result.xlsx”);

Aspose.Cells for Node.js via Java

 var aspose = aspose || {};

aspose.cells = require("aspose.cells");

var fs = require("fs");

var readStream = fs.createReadStream("Book1.xlsx");

aspose.cells.Workbook.createWorkbookFromStream(readStream, function(workbook, err) {

    if (err) {

        console.log("open workbook error");

        return;

    }

   workbook.save('result.xlsx');

    console.log('saved to file');

});

Aspose.Cells for Node.js via Java API相对于Aspose.Cells for Java API的其他限制

1. 不支持从数组、ArrayList、ResultSet 等导入/导出数据。
2. 不支持打印。
