javahtml转pdf
要在Java中将HTML转换为PDF,可以使用iText库。以下是一个示例代码来执行此操作:
```java
import com.itextpdf.text.Document;
import com.itextpdf.text.html.simpleparser.HTMLWorker;
import com.itextpdf.text.pdf.PdfWriter;
import java.io.ByteArrayInputStream;
import java.io.ByteArrayOutputStream;
import java.io.FileOutputStream;
import java.io.InputStream;
import java.nio.charset.StandardCharsets;
public class HtmlToPdfConverter {
public static void main(String[] args) {
String htmlContent = "
Hello
world!
This is a sample HTML content.
";String pdfFilePath = "output.pdf";
try {
InputStream inputStream = new ByteArrayInputStream(htmlContent.getBytes(StandardCharsets.UTF_8));
// Create output stream to write PDF file
FileOutputStream outputStream = new FileOutputStream(pdfFilePath);
// Create document
Document document = new Document();
PdfWriter writer = PdfWriter.getInstance(document
outputStream);
// Open document for writing
document.open();
// Parse HTML content and write it to the PDF document
HTMLWorker htmlWorker = new HTMLWorker(document);
htmlWorker.parse(inputStream);
// Close the document and output stream
document.close();
outputStream.close();
System.out.println("PDF file created successfully.");
} catch (Exception e) {
System.out.println("An error occurred: " + e);
}
}
}
```
以上代码将HTML内容转换为PDF并保存在指定的文件路径中。要将1000字写入HTML内容,只需将`htmlContent`变量更改为您要写入的内容。
请注意,此示例使用iText 5库,您需要将其添加到项目的依赖中。以下是一些常用的Maven依赖,可用于添加iText 5:
```xml
```
希望这可以帮助您将HTML转换为PDF。
