Java 将pdf打印到excel中
我需要将PDF打印到excel工作表中,并将PDF中的数字作为第一列的值,第二列将放置PDF中的文本。我有可以读取PDF的代码,但我很难将其保存到excel中(只有.txt适合我)。多谢各位Java 将pdf打印到excel中,java,Java,我需要将PDF打印到excel工作表中,并将PDF中的数字作为第一列的值,第二列将放置PDF中的文本。我有可以读取PDF的代码,但我很难将其保存到excel中(只有.txt适合我)。多谢各位 公共类saveData{ 公共静态void main(字符串[]args)引发异常{ File File=新文件(“C:/Users/jurkeda1/Desktop/TestERV/layout1_3333445.pdf”); PDDocument文件=null; 试一试{ document=PDDocu

基本上,您可以编写如下工作簿:
// create a new workbook instance
XSSFWorkbook workbook = new XSSFWorkbook();
// ...
// write data into the workbook and format the data
// data may be written by adding and configuring instances of XSSFSheet, XSSFRow and XSSFCell
// ...
// then write the workbook into a file (until here, it is in the RAM)
try {
// create a new FileOutputStream with the path to the file (don't forget the extension)
FileOutputStream fos = new FileOutputStream("Y:\\our\\path\\to\\the\\file.xlsx");
// then write the workbook using that stream
workbook.write(fos);
// force the stream to write everything out of the buffers
fos.flush();
// and close it afterwards
fos.close();
// same for the workbook resource
workbook.close();
} catch (FileNotFoundException e) {
// inform about the special exception, maybe
e.printStackTrace();
} catch (IOException e) {
// inform about the special exception, maybe
e.printStackTrace();
}
您需要了解如何添加新工作表以及如何向工作表中添加新行和单元格。这只是如何将
XSSFWorkbook
的实例写入文件系统的示例。首先,您需要在pom.xml文件中添加Apache POI
依赖项:
</dependencies>
<dependency>
<groupId>org.apache-extras.beanshell</groupId>
<artifactId>bsh</artifactId>

</dependency>
<dependency>
<groupId>org.apache.poi</groupId>
<artifactId>poi</artifactId>
<version>4.0.1</version>
</dependency>
</dependencies>
现在您需要创建工作簿和工作表:

对于(int i=0;i
您的输出应该是这样的:您需要使用外部库来创建Excel文件,如.xlsx。查看并签出类,如
XSSFWorkbook
,例如。File fileX=new File(“C:/Users/jurkeda1/Desktop/TestERV/template_VMV.xlsx”);FileInputStream fip=new FileInputStream(fileX);XSSFWorkbook工作簿=新XSSFWorkbook(fip);但文本仍未保存在Excel中。您需要文件输入流
如果要读取现有的XSSFWorkbook
,请尝试使用文件输出流
