我有一个测试用例，需要下载 xlsx Excel 文件，向其中写入数据，然后保存。使用 apache poi，我能够成功地做到这一点。但是现在，我需要一种方法将该文件转换为 xls 并将其上传到我们的应用程序的文本。

我正在使用documents4j 尝试将文件从xlsx 转换为xls。但它无法创建 xls 文件。因此，当我运行测试时，它找不到文件，并且脚本在那时失败。

import com.documents4j.api.DocumentType;
import com.documents4j.api.IConverter;
import com.documents4j.job.LocalConverter;
import java.io.File;
import java.io.IOException;
import java.util.concurrent.ExecutionException;
import java.util.concurrent.Future;
import java.util.concurrent.TimeUnit;

public class File_Converter {

    public static void convert_XLSX_To_XLS() throws InterruptedException, ExecutionException, IOException {
        File wordFile = new File("C:\\Users\\Jeff15\\Downloads\\scheduleUpload.xlsx"),
                target = new File("C:\\Users\\Jeff15\\Downloads\\scheduleUpload.xls");

        IConverter converter = LocalConverter.builder()
                .baseFolder(new File("C:\\Users\\Jeff15\\Downloads\\"))
                .workerPool(20, 25, 2, TimeUnit.SECONDS)
                .processTimeout(5, TimeUnit.SECONDS)
                .build();

        Future<Boolean> conversion = converter.convert(wordFile)
                .as(DocumentType.XLSX)
                .to(target)
                .as(DocumentType.XLS)
                // .prioritizeWith(1000) // optional
                .schedule();
    }
}

我有以下 Maven 依赖项：

documents4j-transformer-msoffice-base 1.0.3
documents4j-api 1.0.3
documents4j-util-conversion 1.0.3
documents4j-transformer-api 1.0.3
documents4j-util-all 1.0.3
documents4j-local 1.0.3
documents4j-util-ws 1.0.3
documents4j-util-standalone 1.0.3
documents4j-transformer-msoffice-excel 1.0.3
documents4j-test 1.0.3
documents4j-transformer-msoffice-test 1.0.3
documents4j-transformer-msoffice 1.0.3
documents4j-aggregation 1.0.3

我没有收到任何相关错误。脚本在找不到 xls 文件时失败，然后单击“上传”按钮。

看来，它是降级 excel 文件版本的错误。我检查并发现我们可以从 XLS 更改为 XLSX，但反向不起作用。我建议你使用 apache poi 来转换格式。希望这对你有用。
