使用Spring Boot创建PDF到Word的转换程序需要几个步骤。可以使用现有的库来处理转换过程。使用ApachePDFBox进行PDF操作和使用ApachePOI创建Word文档的过程。
-
添加依赖项:
将以下依赖项添加到"pom.xml"文件中,以在项目中包括PDFBox和POI:
xml<dependencies> <dependency> <groupId>org.apache.pdfbox</groupId> <artifactId>pdfbox</artifactId> <version>2.0.27</version> </dependency> <dependency> <groupId>org.apache.poi</groupId> <artifactId>poi</artifactId> <version>4.1.2</version> </dependency> <dependency> <groupId>org.apache.poi</groupId> <artifactId>poi-ooxml</artifactId> <version>4.1.2</version> </dependency> </dependencies>
-
创建 Service:
创建一个处理PDF到Word转换的服务类:
javaimport org.apache.pdfbox.pdmodel.PDDocument; import org.apache.pdfbox.text.PDFTextStripper; import org.apache.poi.xwpf.usermodel.XWPFDocument; import org.apache.poi.xwpf.usermodel.XWPFParagraph; import org.apache.poi.xwpf.usermodel.XWPFRun; import org.springframework.stereotype.Service; import java.io.ByteArrayInputStream; import java.io.ByteArrayOutputStream; import java.io.IOException; @Service public class PdfToWordConverterService { public byte[] convertPdfToWord(byte[] pdfBytes) throws IOException { try (PDDocument pdfDocument = PDDocument.load(new ByteArrayInputStream(pdfBytes)); XWPFDocument wordDocument = new XWPFDocument()) { PDFTextStripper pdfTextStripper = new PDFTextStripper(); String text = pdfTextStripper.getText(pdfDocument); XWPFParagraph paragraph = wordDocument.createParagraph(); XWPFRun run = paragraph.createRun(); run.setText(text); ByteArrayOutputStream outputStream = new ByteArrayOutputStream(); wordDocument.write(outputStream); return outputStream.toByteArray(); } } }
-
创建控制器:
创建一个Spring MVC控制器来处理传入的请求。此控制器应使用"PdfToWordConverterService"来执行转换.
javaimport org.springframework.beans.factory.annotation.Autowired; import org.springframework.web.bind.annotation.PostMapping; import org.springframework.web.bind.annotation.RequestBody; import org.springframework.web.bind.annotation.RestController; @RestController public class PdfToWordController { @Autowired private PdfToWordConverterService converterService; @PostMapping("/convert") public byte[] convertPdfToWord(@RequestBody byte[] pdfBytes) throws IOException { return converterService.convertPdfToWord(pdfBytes); } }
