documents4j

package org.jeecg.modules.demo.utils;

import com.aspose.words.document;
import com.aspose.words.License;
import com.aspose.words.SaveFormat;

import java.io.*;
import org.springframework.core.io.ClassPathResource;

public class WordPdfUtils {

    public static boolean getLicense() {
        boolean result = false;
        try {
            ClassPathResource classPathResource = new ClassPathResource("license.xml");
            License aposeLic = new License();
            aposeLic.setLicense(classPathResource.getInputStream());
            result = true;
        } catch (Exception e) {
            e.printStackTrace();
        }
        return result;
    }

    public static boolean doc2pdf(InputStream inputStream, OutputStream outputStream) {
        if (!getLicense()) { // 验证License 若不验证则转化出的pdf文档会有水印产生
            return false;
        }
        try {
            document doc = new document(inputStream);
            doc.save(outputStream, SaveFormat.PDF);
        } catch (Exception e) {

        }
        return true;
    }
}

resources下license.xml可以去除水印
