Springboot集成OpenOffice实现各类文件转PDF，在线预览

ops 2025/7/1 3:21:50

一、下载安装OpenOffice

Springboot集成OpenOffice，首先计算机环境是需要OpenOffice的。

官网下载地址Apache OpenOffice - Official Download

下载完成双击exe文件进行安装

需要先解压缩再进行安装，解压缩可以修改路径
安装时有典型安装和自定义安装。典型安装默认装在C盘，自定义安装可修改安装位置

安装完成后进入到安装目录，再进入到program文件

在输入栏输入cmd再回车，进入命令行窗口

在命令行窗口内输入以下语句进行启动：

soffice -headless -accept="socket,host=127.0.0.1,port=8100;urp;" -nofirststartwizard

二、Springboot项目集成OpenOffice

pom文件中先导入相关依赖：

        <dependency><groupId>org.jodconverter</groupId><artifactId>jodconverter-core</artifactId><version>4.2.2</version></dependency><dependency><groupId>org.jodconverter</groupId><artifactId>jodconverter-spring-boot-starter</artifactId><version>4.2.2</version></dependency><dependency><groupId>org.jodconverter</groupId><artifactId>jodconverter-local</artifactId><version>4.2.2</version></dependency>

yml配置文件：

jodconverter:local:enabled: trueoffice-home: C:\Program Files (x86)\OpenOffice 4 #安装路径max-tasks-per-process: 10port-numbers: 8100 #端口号

由于我代码中将用户上传的文件、以及转换后的文件都存储在计算机上，所以我配置了两个地址

file:source_path: D:/sourceFiles/target_path: D:/targetFiles/

编写控制器进行实现：

import com.wk.convert.config.FileProperties;
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiOperation;
import lombok.SneakyThrows;
import lombok.extern.slf4j.Slf4j;
import org.apache.commons.io.IOUtils;
import org.apache.pdfbox.rendering.PDFRenderer;

import java.util.concurrent.CompletableFuture;@Slf4j
@RestController
@RequestMapping()
@Api(tags = "文件")
public class FileController {@Autowiredprivate DocumentConverter converter;@SneakyThrows@ApiOperation(value = "文件预览")@PostMapping("/viewPDF")public void viewPDF(HttpServletResponse response, @RequestPart("multipartFile") MultipartFile multipartFile) {File targetFile = getPDFFile(multipartFile);if (targetFile == null) return;// 返回前端预览String pdfPath = targetFile.getAbsolutePath();try {ServletOutputStream outputStream = response.getOutputStream();InputStream in = Files.newInputStream(new File(pdfPath).toPath());IOUtils.copy(in, outputStream);in.close();outputStream.close();} catch (Exception e) {e.printStackTrace();}}@ApiOperation(value = "文件转换PDF")@PostMapping("/toPDF")public ResponseEntity<InputStreamResource> toPDF(HttpServletRequest request, HttpServletResponse response, @RequestPart("multipartFile") MultipartFile multipartFile) throws IOException, OfficeException {File targetFile = getPDFFile(multipartFile);if (targetFile == null) return null;// 返回文件InputStream inputStream = Files.newInputStream(new File(targetFile.getAbsolutePath()).toPath());HttpHeaders headers = new HttpHeaders();headers.add("Content-Disposition", "attachment; filename=" + targetFile.getName());return ResponseEntity.ok().headers(headers).contentType(MediaType.APPLICATION_OCTET_STREAM).body(new InputStreamResource(inputStream));}private File getPDFFile(MultipartFile multipartFile) throws IOException, OfficeException {if (multipartFile.isEmpty()) {log.info("文件为空");return null;}File file1 = new File(FileProperties.SOURCE_PATH);if (!file1.exists()) file1.mkdir();File file2 = new File(FileProperties.TARGET_PATH);if (!file2.exists()) file2.mkdir();String originalFilename = Objects.requireNonNull(multipartFile.getOriginalFilename());String fileName = UUID.randomUUID().toString().replaceAll("-", "").substring(0, 6) + "_" + originalFilename.split("\\.")[0];File sourceFile = new File(FileProperties.SOURCE_PATH + fileName + "." + originalFilename.substring(originalFilename.lastIndexOf(".") + 1));try (FileOutputStream fos = new FileOutputStream(sourceFile)) {fos.write(multipartFile.getBytes());}File targetFile = new File(FileProperties.TARGET_PATH + fileName + ".pdf");converter.convert(sourceFile).to(targetFile).execute();return targetFile;}}

文件配置类

import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Configuration;@Configuration
public class FileProperties {public static String SOURCE_PATH;public static String TARGET_PATH;@Value("${file.source_path}")public void setSourcePath(String sourcePath) {SOURCE_PATH = sourcePath;}@Value("${file.target_path}")public void setTargetPath(String targetPath) {TARGET_PATH = targetPath;}
}

附上简单前端代码：

<!DOCTYPE html>
<html>
<head><meta charset="UTF-8"><title>File Converter</title>
</head>
<body>
<h1>Converter</h1><br>
<form action="/viewPDF" method="post" enctype="multipart/form-data"><label>文件预览：</label><input type="file" name="multipartFile" accept="application/*"><button type="submit">submit</button>
</form><br>
<form action="/toPDF" method="post" enctype="multipart/form-data"><label>文件转PDF：</label><input type="file" name="multipartFile" accept="application/*"><button type="submit">submit</button>
</form></body>
</html>
