判断许可证是否成功加载

确定许可证是否成功加载

以下代码在设置许可证之前访问Workbook.isLicensed()方法并返回false。然后加载许可证并再次访问属性,此时返回true。

// For complete examples and data files, please go to https://github.com/aspose-cells/Aspose.Cells-for-Java
// The path to the documents directory.
String dataDir = Utils.getDataDir(DeterminetheLicenseLoadedSuccessfully.class);
// Create workbook object before setting a license
Workbook workbook = new Workbook();
// Check if the license is loaded or not
// It will return false
System.out.println(workbook.isLicensed());
// Set the license now
String licPath = dataDir + "Aspose.Total.lic";
com.aspose.cells.License lic = new com.aspose.cells.License();
lic.setLicense(licPath);
// Check if the license is loaded or not
// Now it will return true
System.out.println(workbook.isLicensed());
