java aspose的集成

1. 导入aspose.slides-15.9.0.jar、aspose-cad-20.4.jar、aspose-cells-8.5.2.jar、aspose-words-18.5.0718-jdk16.jar四个jar包，由于这个几jar包不支持maven，所以需要手动导入。
2. 将license.xml放到src/main/resources下
3. 工具类

import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.util.Date;

		FileOutputStream os = null;
		try {

			File file = new File(outPath); // 新建一个空白pdf文档
			os = new FileOutputStream(file);
			Document doc = new Document(inPath); // Address是将要被转化的word文档
			doc.save(os, SaveFormat.PDF);// 全面支持DOC, DOCX, OOXML, RTF HTML, OpenDocument, PDF,

			long now = System.currentTimeMillis();
			System.out.println("pdf转换成功，共耗时：" + ((now - old) / 1000.0) + "秒"); // 转化用时

	}
	//cad dwg 文件转 pdf
	public static void dwg2pdf(String oldUrl, String pdfUrl) {
		if (!getLicense()) {
			return;
		}

		// TODO Auto-generated method stub
		com.aspose.cad.Image objImage = com.aspose.cad.Image.load(oldUrl);
		// Create an instance of PdfOptions
		PdfOptions pdfOptions = new PdfOptions();
		pdfOptions.setVectorRasterizationOptions(new CadRasterizationOptions());

		pdfOptions.setCorePdfOptions(new PdfDocumentOptions());
		pdfOptions.getCorePdfOptions().setCompliance(PdfCompliance.PdfA1a);
		long curTime = new Date().getTime();
		// 初始化pdf文件 dataDir（本地） urlPrefix:http
		objImage.save(pdfUrl, pdfOptions);
	}

}

4.调用

public static void main(String [] args){
	//将word文档转成PDF，根据工具类的名称进行调用，前面是要转的文件，后面是要转成的文件
	ConvertPdfUtil.doc2pdf("文档的地址","要转成的pdf的地址");
}

5. 导入jar包的步骤
   选中项目-》右键-》build path，然后
   
   6. 4个jar包的地址和license.xml的地址
