今天药忘吃喽~ 2023-02-15 05:18 12阅读 0赞

本文向您展示了如何使用[Apache PDFBox][]读取Java中的PDF文件。

## 1.获取PDFBox ##

pom.xml

<dependency>
            <groupId>org.apache.pdfbox</groupId>
            <artifactId>pdfbox</artifactId>
            <version>2.0.6</version>
    </dependency>

## 2.打印PDF文件 ##

从PDF文件提取所有文本的示例。

ReadPdf.java

package com.mkyong;
    
    import org.apache.pdfbox.pdmodel.PDDocument;
    import org.apache.pdfbox.text.PDFTextStripper;
    import org.apache.pdfbox.text.PDFTextStripperByArea;
    
    import java.io.File;
    import java.io.IOException;
    
    public class ReadPdf {
    
        public static void main(String[] args) throws IOException {
    
            try (PDDocument document = PDDocument.load(new File("/path-to/abc.pdf"))) {
    
                document.getClass();
    
                if (!document.isEncrypted()) {
    			
                    PDFTextStripperByArea stripper = new PDFTextStripperByArea();
                    stripper.setSortByPosition(true);
    
                    PDFTextStripper tStripper = new PDFTextStripper();
    
                    String pdfFileInText = tStripper.getText(document);
                    //System.out.println("Text:" + st);
    
    				// split by whitespace
                    String lines[] = pdfFileInText.split("\\r?\\n");
                    for (String line : lines) {
                        System.out.println(line);
                    }
    
                }
    
            }
    
        }
    }
