使用JAVA从PDF中获取文字信息，目前只能读取文字型PDF。图片型PDF尚在研究
1.导入Maven依赖
<dependency>
<groupid>org.apache.pdfbox</groupid>
<artifactid>pdfbox</artifactid>
</dependency>
2.示例代码
package com.example.pdfuntil;
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.FileWriter;
import java.io.IOException;
public class ReadPdf {
public static void main(String[] args) {
String inputPath = "C:/example/PdfTest/pdf_demo1.pdf";
String outputPath = "C:/example/PdfTest/demo.txt";
readPdf(inputPath, outputPath);
}
public static void readPdf(String inputPath, String outputPath) {
try (PDDocument document = PDDocument.load(new File(inputPath))) {
if (!document.isEncrypted()) {
PDFTextStripperByArea stripper = new PDFTextStripperByArea();
stripper.setSortByPosition(true);
PDFTextStripper tStripper = new PDFTextStripper();
String pdfFileInText = tStripper.getText(document);
String[] lines = pdfFileInText.split("\\r?\\n");
FileWriter fw = new FileWriter(outputPath);
for (String line : lines) {
System.out.println(line);
fw.write(line + "\n");
}
fw.close();
document.close();
}
} catch (IOException e) {
e.printStackTrace();
}
}
}
