用Scala语言生成HTML到PDF

我已经用JAVA从HTML生成Pdf，效果很好。 但我需要用“scala”来完成这个。尽管我像在JAVA中那样导入了所有JAR，但IText渲染器还是出现了一个问题。 请建议我以同样的方式实现输出

Java代码：

import java.io.*;
import com.lowagie.text.DocumentException;
import org.xhtmlrenderer.pdf.ITextRenderer;

public class Htmltopdf_hcue {

    public static void main(String[] args) throws IOException, DocumentException {
        String File_To_Convert = "F:/Pdf_Generation/Appointment Schedule_Fair_Edit.html";
        //String File_To_Convert = "C:/Users/hCue/Desktop/img.html";        
        String url = new File(File_To_Convert).toURI().toURL().toString();
        System.out.println(""+url);
        String HTML_TO_PDF = "F:/Pdf_Generation/TheEndPDF344444444444.pdf";
        OutputStream os = new FileOutputStream(HTML_TO_PDF);
        ITextRenderer renderer = new ITextRenderer();
        renderer.setDocument(url);      
        renderer.layout();
        renderer.createPDF(os);        
        os.close();
    }   
}

import java.awt.image.BufferedImage
import java.io.File

import java.io.FileOutputStream
import java.io.FileInputStream
import java.io.InputStreamReader
import java.net.URL
import javax.imageio.ImageIO
import java.io
import com.lowagie.text.DocumentException;
import org.xhtmlrenderer.pdf.ITextRenderer;
import org.xhtmlrenderer.pdf.ITextTextRenderer
object Hello{
    def main(args: Array[String]) { 
    var fos: FileOutputStream = null
    val File_To_Convert  ="F:/Pdf_Generation/Appointment Schedule_Fair_Edit.html";
    val url = new File(File_To_Convert).toURI().toURL().toString();
    val HTML_TO_PDF = "F:/Pdf_Generation/TheEndPDF344444444444.pdf";
    fos = new FileOutputStream(HTML_TO_PDF);
    ITextRenderer renderer = new ITextRenderer();/*Getting Error as Value renderer is not a member object of org.xhtmlrenderer.pdf.ITextRenderer */
        renderer.setDocument(url);      
        renderer.layout();
        renderer.createPDF(fos);  
        fos.close();

    } 

}

Scala代码：

import java.io.*;
import com.lowagie.text.DocumentException;
import org.xhtmlrenderer.pdf.ITextRenderer;

public class Htmltopdf_hcue {

    public static void main(String[] args) throws IOException, DocumentException {
        String File_To_Convert = "F:/Pdf_Generation/Appointment Schedule_Fair_Edit.html";
        //String File_To_Convert = "C:/Users/hCue/Desktop/img.html";        
        String url = new File(File_To_Convert).toURI().toURL().toString();
        System.out.println(""+url);
        String HTML_TO_PDF = "F:/Pdf_Generation/TheEndPDF344444444444.pdf";
        OutputStream os = new FileOutputStream(HTML_TO_PDF);
        ITextRenderer renderer = new ITextRenderer();
        renderer.setDocument(url);      
        renderer.layout();
        renderer.createPDF(os);        
        os.close();
    }   
}

import java.awt.image.BufferedImage
import java.io.File

import java.io.FileOutputStream
import java.io.FileInputStream
import java.io.InputStreamReader
import java.net.URL
import javax.imageio.ImageIO
import java.io
import com.lowagie.text.DocumentException;
import org.xhtmlrenderer.pdf.ITextRenderer;
import org.xhtmlrenderer.pdf.ITextTextRenderer
object Hello{
    def main(args: Array[String]) { 
    var fos: FileOutputStream = null
    val File_To_Convert  ="F:/Pdf_Generation/Appointment Schedule_Fair_Edit.html";
    val url = new File(File_To_Convert).toURI().toURL().toString();
    val HTML_TO_PDF = "F:/Pdf_Generation/TheEndPDF344444444444.pdf";
    fos = new FileOutputStream(HTML_TO_PDF);
    ITextRenderer renderer = new ITextRenderer();/*Getting Error as Value renderer is not a member object of org.xhtmlrenderer.pdf.ITextRenderer */
        renderer.setDocument(url);      
        renderer.layout();
        renderer.createPDF(fos);  
        fos.close();

    } 

}

提前谢谢你

将渲染定义为

val

import java.awt.image.BufferedImage
import java.io.File

import java.io.FileOutputStream
import java.io.FileInputStream
import java.io.InputStreamReader
import java.net.URL
import javax.imageio.ImageIO
import java.io
import com.lowagie.text.DocumentException
import org.xhtmlrenderer.pdf.ITextRenderer

object Hello{
  def main(args: Array[String]) {
    var fos: FileOutputStream = null
    val File_To_Convert  ="F:/Pdf_Generation/Appointment Schedule_Fair_Edit.html"
    val url = new File(File_To_Convert).toURI().toURL().toString()
    val HTML_TO_PDF = "F:/Pdf_Generation/TheEndPDF344444444444.pdf"
    fos = new FileOutputStream(HTML_TO_PDF)
    val renderer = new ITextRenderer()
    renderer.setDocument(url)
    renderer.layout()
    renderer.createPDF(fos)
    fos.close()

  }

}

您会收到什么错误消息？ITextRenderer=newitextrenderer（）/*值呈现器不是对象org.xhtmlrenderer.pdf.ITextRenderer*/renderer.setDocument（url）的成员；/*未找到值renderer*/renderer.layout（）；/*未找到值渲染器*/renderer.createPDF（os）；/*找不到值渲染器*/非常感谢@FaigB。这对我来说真的很有效。。！您好@FaigB，对于独立程序来说，它工作得很好，但实际上我有scala项目。但是当我编译整个项目的时候。我收到以下错误：[error]F:\WorkSpacescala\helper\hcueDocuments.scala:37:对象lowagie不是包com的成员[error]import com.lowagie.text.DocumentException；[error]^[error]F:\WorkSpace\scala\helper\hcueDocuments.scala:38:object xhtmlrenderer不是包组织的成员[error]import org.xhtmlrenderer.pdf.ITextRenderer；[error]^[error]F:\WorkSpace\scala\helper\hcueDocuments.scala:102:未找到：键入ITextRenderer[error]var renderer=new ITextRenderer（）[error]^[error]发现三个错误[error]（编译：编译）编译失败已将所需的JAR导入到项目中。。！出现此问题的可能性有多大？build.sbt的外观如何？
