Java中可以使用Apache PDFBox库将InputStream转换为PDF文件。具体步骤如下:
1. 引入PDFBox库
```java
<dependency>
<groupId>org.apache.pdfbox</groupId>
<artifactId>pdfbox</artifactId>
<version>2.0.22</version>
</dependency>
```
2. 创建一个PDDocument对象
```java
PDDocument document = new PDDocument();
```
3. 使用PDDocument对象的load方法将InputStream加载到PDDocument中
```java
document.load(inputStream);
```
4. 关闭InputStream
```java
inputStream.close();
```
5. 保存PDDocument为PDF文件
```java
document.save("output.pdf");
```
6. 关闭PDDocument
```java
document.close();
```
完整代码示例:
```java
import java.io.*;
import org.apache.pdfbox.pdmodel.*;
import org.apache.pdfbox.exceptions.*;
public class InputStreamToPDF {
public static void main(String[] args) throws IOException, InvalidPasswordException {
InputStream inputStream = new FileInputStream("input.pdf");
PDDocument document = new PDDocument();
document.load(inputStream);
inputStream.close();
document.save("output.pdf");
document.close();
}
}
```
