需求,用户将用户上传的word文件转换成为pdf格式,然后返回
第一步:引入依赖
XML
<dependency>
<groupId>aspose</groupId>
<artifactId>aspose-words</artifactId>
<version>15.8.0-jdk16</version>
</dependency>
<dependency>
<groupId>aspose</groupId>
<artifactId>aspose-slides</artifactId>
<version>19.3</version>
</dependency>
温馨提示:
如果这两个jar包maven下载出错,就直接从我的网盘下载,然后将jar包放到对应的本地maven仓库下
网盘链接
链接:https://pan.baidu.com/s/1ytKGx4EXfK7OWRsOC6yhJg
提取码:6666
jar包所在位置(我的仅供参考,以你自己的实际maven地址为准)
下载好放到本地后,在idea刷新maven就可以了
第二步:编写工具类
java
import com.aspose.words.Document;
import com.aspose.words.License;
import com.aspose.words.SaveFormat;
import java.io.*;
/**
* word转pdf工具类
*
* @author shmily
*/
public class Word2PdfUtil {
/**
* 许可证字符串(可以放到resource下的xml文件中也可)
*/
private static final String LICENSE = "<License>" +
"<Data>" +
"<Products><Product>Aspose.Total for Java</Product><Product>Aspose.Words for Java</Product></Products>" +
"<EditionType>Enterprise</EditionType>" +
"<SubscriptionExpiry>20991231</SubscriptionExpiry>" +
"<LicenseExpiry>20991231</LicenseExpiry>" +
"<SerialNumber>8bfe198c-7f0c-4ef8-8ff0-acc3237bf0d7</SerialNumber>" +
"</Data>" +
"<Signature>sNLLKGMUdF0r8O1kKilWAGdgfs2BvJb/2Xp8p5iuDVfZXmhppo+d0Ran1P9TKdjV4ABwAgKXxJ3jcQTqE/2IRfqwnPf8itN8aFZlV3TJPYeD3yWE7IT55Gz6EijUpC7aKeoohTb4w2fpox58wWoF3SNp6sK6jDfiAUGEHYJ9pjU=</Signature>" +
"</License>";
/**
* 设置 license 去除水印
*/
private static void setLicense() {
ByteArrayInputStream byteArrayInputStream = new ByteArrayInputStream(LICENSE.getBytes());
License license = new License();
try {
license.setLicense(byteArrayInputStream);
} catch (Exception e) {
e.printStackTrace();
}
}
/**
* word 转 pdf 生成至指定路径,pdf为空则上传至word同级目录
*
* @param wordPath word文件路径
* @param pdfPath pdf文件路径
*/
public static void wordConvertPdfFile(String wordPath, String pdfPath) {
FileOutputStream fileOutputStream = null;
try {
pdfPath = pdfPath == null ? getPdfFilePath(wordPath) : pdfPath;
setLicense();
File file = new File(pdfPath);
fileOutputStream = new FileOutputStream(file);
Document doc = new Document(wordPath);
doc.save(fileOutputStream, SaveFormat.PDF);
} catch (Exception e) {
e.printStackTrace();
} finally {
try {
assert fileOutputStream != null;
fileOutputStream.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
/**
* word 转 pdf 生成byte字节流
*
* @param wordPath word所在的目录地址
* @return
*/
public static byte[] wordConvertPdfByte(String wordPath) {
ByteArrayOutputStream fileOutputStream = null;
try {
setLicense();
fileOutputStream = new ByteArrayOutputStream();
Document doc = new Document(wordPath);
doc.save(fileOutputStream, SaveFormat.PDF);
return fileOutputStream.toByteArray();
} catch (Exception e) {
e.printStackTrace();
} finally {
try {
assert fileOutputStream != null;
fileOutputStream.close();
} catch (IOException e) {
e.printStackTrace();
}
}
return null;
}
/**
* 获取 生成的 pdf 文件路径,默认与源文件同一目录
*
* @param wordPath word文件
* @return 生成的 pdf 文件
*/
private static String getPdfFilePath(String wordPath) {
int lastIndexOfPoint = wordPath.lastIndexOf(".");
String pdfFilePath = "";
if (lastIndexOfPoint > -1) {
pdfFilePath = wordPath.substring(0, lastIndexOfPoint);
}
return pdfFilePath + ".pdf";
}
}
第三步:验证controller
java
import com.xp.utils.Word2PdfUtil;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
@GetMapping("word2Pdf")
public void word2Pdf() {
Word2PdfUtil.wordConvertPdfFile("C:\\Users\\Administrator\\Desktop\\aaa\\you.docx","C:\\Users\\Administrator\\Desktop\\aaa\\success.pdf");
}
@GetMapping("word2PdfByte")
public byte[] word2PdfByte() {
return Word2PdfUtil.wordConvertPdfByte("C:\\Users\\Administrator\\Desktop\\aaa\\you.docx");
}
看效果
