使用jacob将word转换为PDF，转换前如何接受所有修订？

[知道就是你]

1.环境： JDK1.6 jacob-1.18
2.接受所有修订，尝试及对应错误信息
(1) Dispatch.call(doc, "AcceptAllRevisions");


(2) Dispatch.put(doc, "AcceptAllRevisions", true);



3.源代码：

import java.util.concurrent.ExecutorService;
import java.util.concurrent.Executors;
import java.util.concurrent.Future;

Dispatch.put(doc, "AcceptAllRevisions", true) ；注释掉就ok了

[知道就是你]

如果注释掉，效果不尽人意！ 参考转换结果如下：

Free Spire.Doc for Java里面有个方法acceptChanges()，可以设置接受所有修订后直接将Word转为PDF,参考代码：

import com.spire.doc.*;

public class Main {
    public static void main(String[] args) {
        //加载word示例文档
        Document doc = new Document();
        doc.loadFromFile("sample.docx");

        //启用修订功能
        doc.setTrackChanges(true);
        
        //判断文档是否有修改
        if (doc.hasChanges())

            //接受修订
            doc.acceptChanges();

        //保存结果文件
        doc.saveToFile("Word转PDF.pdf", FileFormat.PDF);
        doc.close();
    }
}
