springcloud doc转docx

根据提供的引用[1]，可以使用Apache POI库将Spring Cloud文档从doc格式转换为docx格式。下面是一个Java代码示例：

import java.io.FileInputStream;
import java.io.FileOutputStream;
import org.apache.poi.hwpf.HWPFDocument;
import org.apache.poi.hwpf.converter.WordToConverter;
import org.apache.poi.hwpf.usermodel.Range;
import org.apache.poi.xwpf.usermodel.XWPFDocument;

public class DocToDocxConverter {
    public static void main(String[] args) throws Exception {
        // 读取doc文件
        FileInputStream fis = new FileInputStream("springcloud.doc");
        HWPFDocument doc = new HWPFDocument(fis);

        // 将doc文件内容复制到docx文件中
        XWPFDocument docx = new XWPFDocument();
        WordToConverter converter = new WordToConverter(docx);
        converter.processDocument(doc, new Range(0, doc.getRange().numParagraphs()), null);

        // 保存docx文件
        FileOutputStream fos = new FileOutputStream("springcloud.docx");
        docx.write(fos);

        // 关闭流
        fos.close();
        fis.close();
    }
}

请注意，此代码需要Apache POI库的支持。你需要将以下依赖项添加到你的Maven项目中：
