一、为什么停更了四五个月
还有一个原因：就是最近朋友给介绍了一个对象，比较忙(*^▽^*
二、PDF相关文件操作
1.引入依赖
<dependency>
<groupId>com.luhuiguo</groupId>
<artifactId>aspose-pdf</artifactId>
<version>23.1</version>
</dependency>
2.代码实现（只贴关键代码，代码我会放到GitHub跟Gitee上面，大家自取、还有完整的接口文档我都会放出来）
① 上传OSS工具类 OssUpLoadTools
/**
* @description: 获取文件保存地址
* @return: java.lang.String
* @author: zhouhong
* @date: 2023/4/30 12:36
*/
public String getSavePath( {
ApplicationHome applicationHome = new ApplicationHome(this.getClass(;
// 保存目录位置根据项目需求可随意更改
return applicationHome.getDir(.getParentFile(
.getParentFile(.getAbsolutePath( + "\\src\\main\\resources\\templates\\";
}
/**
* @description: 上传文件到阿里云OSS
* @return: java.lang.String
* @author: zhouhong
* @date: 2023/5/1 22:55
*/
public String uploadOssFile(String fileName, File file{
// 创建OSSClient实例。
OSS ossClient = ossConfig.getOssClient(;
try {
// 创建PutObjectRequest对象。
PutObjectRequest putObjectRequest = new PutObjectRequest(ossConfig.getBucketName(,
fileName, file;
putObjectRequest.setProcess("true";
// 上传文件。
PutObjectResult result = ossClient.putObject(putObjectRequest;
// 如果上传成功，则返回200。
if (result.getResponse(.getStatusCode( == 200 {
return result.getResponse(.getUri(;
}
} catch (OSSException oe {
} catch (ClientException ce {
} finally {
if (ossClient != null {
ossClient.shutdown(;
}
}
return null;
}
② PDF转其他文件
/**

* @return: java.util.List<java.lang.String>
* @author: zhouhong
* @date: 2023/5/1 23:34
*/
@Override
public List<String> pdfToFile(MultipartFile file,String type {
List<String> res = new ArrayList<>(;
String checkType = FilenameUtils.getExtension(file.getOriginalFilename(;
if (!"pdf".equals(checkType {
throw new ServiceException(1, "输入文件不是PDF文件！";
}
try {
switch (type.toUpperCase( {

}
return null;
}
/**

pdfFileEditor.concatenate(chilPdfPath, mergePdfPath;
// 读取文件上传OSS
File outputfile = new File(mergePdfPath;
String resUrl = ossUpLoadTools.uploadOssFile(mergeFileName, outputfile;
outputfile.delete(;
return resUrl;
} catch (Exception e {
e.printStackTrace(;

// }
default:{}
}
} catch (Exception e {
e.printStackTrace(;
}
return null;
}
private String SwitchFile(MultipartFile file, int saveFormat, String suffix {
String url = "";
try {
long old = System.currentTimeMillis(;
String fileName = UUID.randomUUID( + "." + suffix;
String filePath = ossUpLoadTools.getSavePath( + "/" + fileName;
FileOutputStream os = new FileOutputStream(filePath;
//加载源文件数据
Workbook excel = new Workbook(file.getInputStream(;
//设置转换文件类型并转换
excel.save(os, saveFormat;
os.close(;
File outputfile = new File(filePath;
url = ossUpLoadTools.uploadOssFile(fileName, outputfile;
outputfile.delete(;
long now = System.currentTimeMillis(;
log.info("共耗时：" + ((now - old / 1000.0 + "秒";
} catch (Exception e {
e.printStackTrace(;
}
return url;
}
四、Word相关操作
1.引入相关依赖
<dependency>
<groupId>com.luhuiguo</groupId>
<artifactId>aspose-words</artifactId>
<version>23.1</version>
</dependency>
2.关键代码
@Override
public String wordToFile(MultipartFile file, String type {
String checkType = FilenameUtils.getExtension(file.getOriginalFilename(;
if (!"doc".equals(checkType && !"docx".equals(checkType {
throw new ServiceException(1, "输入文件不是Word文件！";
}
try {
switch (type.toUpperCase( {
case "TEXT" : {
return switchFile(file, SaveFormat.TEXT, "txt";
}
case "PDF" : {
return switchFile(file, com.aspose.words.SaveFormat.PDF, "pdf";
}
/*************** 需要操作每一页Word文件，一般Word类的直接电脑操作，应该用不上************/
// case "PNG" : {

<version>23.1</version>
</dependency>
2.关键部分代码
@Override
public String PptToFile(MultipartFile file, String type {
// 获取文件后缀名
String checkType = FilenameUtils.getExtension(file.getOriginalFilename(;
if (!"ppt".equals(checkType && !"pptx".equals(checkType {
throw new ServiceException(1, "输入文件不是PPT文件！";
}
try {

//设置转换文件类型并转换
ppt.save(os, saveFormat;
os.close(;
File outputfile = new File(filePath;
url = ossUpLoadTools.uploadOssFile(fileName, outputfile;
// 删除临时文件
outputfile.delete(;
long now = System.currentTimeMillis(;
log.info("共耗时：" + ((now - old / 1000.0 + "秒";
return url;
}catch (IOException e {
e.printStackTrace(;
}
return url;
}
六、同时我还找到了一个几乎所有文件转换图片的工具类，被我稍作修改，就可以实现文件转图片，返回阿里云图片的储存地址集合啦
七、演示（演示有两个意思一下，别的大家自行测试）
1.PDF转Word
我有一个 cs.pdf 的PDF文件，通过调用PDF 转其他文件的接口，将其转换为 Wprd 形式
编程笔记 » 用Aspose-Java免费实现 PDF/Word/Excel/Word互相转换并将转换过得文件上传OSS,返回转换后的文件路径
