java 读取数据 并分开打印出来_如何通过java来对PDF文件的合并，拆分以及对内容读取的处理...

项目用打印出来的pdf需要电子化处理。就用到了读取pdf内容，合并pdf文件，以及拆分pdf的处理。

废话不多说，直接上代码。

import java.io.File;

import java.io.IOException;

import java.util.List;

import org.apache.pdfbox.multipdf.Splitter;

import org.apache.pdfbox.pdmodel.PDDocument;

public class PdfSplit {

public static void main(String[] args) throws IOException {

try {

Splitter splitter = new Splitter();

PDDocument source = PDDocument.load(new File("C:/temp/combine.pdf"));

List documents = splitter.split(source);

int i = 0;

for (PDDocument document : documents) {

i++;

document.save("C:/temp/split/" + "out" + i + ".pdf");

}

} finally {

}

}

}

========================================

合并多个pdf 为1个pdf文件

import java.io.File;

import java.io.IOException;

import org.apache.pdfbox.io.MemoryUsageSetting;

import org.apache.pdfbox.multipdf.PDFMergerUtility;

public class PdfCombining {

public static void main(String[] args) throws IOException {

try {

PDFMergerUtility merger = new PDFMergerUtility();

merger.addSource(new File("C:/temp/test_excel.pdf"));

merger.addSource(new File("C:/temp/test_word.pdf"));

merger.addSource(new File("C:/temp/test_ppt.pdf"));

merger.setDestinationFileName("C:/temp/office3page.pdf");

merger.mergeDocuments(MemoryUsageSetting.setupTempFileOnly());

}finally {

System.out.println("combining end");

}

}

}

========================================

读取pdf上面的内容

import java.io.File;

import java.io.IOException;

import org.apache.pdfbox.pdmodel.PDDocument;

import org.apache.pdfbox.text.PDFTextStripper;

public class PdfGetStr {

public static final void main(String[] args) throws IOException {

File file = new File("C:/temp/office3page.pdf");

PDDocument document = PDDocument.load(file);

int lastPage = document.getNumberOfPages();

System.out.println("pageNum：" + document.getNumberOfPages());

PDFTextStripper stripper = new PDFTextStripper();

stripper.setStartPage(0);

stripper.setEndPage(3);

String text = stripper.getText(document);

System.out.println(text);

}

}
