请问云效中怎么使用java做过将pdf(内容含有文字,图片)文档的内容插入到word文档中?word文档的一个表格。
您可以使用Apache POI库来实现Java代码中的PDF转Word功能。首先,您需要将PDF文件读入到内存中,然后使用Apache PDFBox提供的功能将其转换为文本格式。接着,使用POI库读入Word文件,然后将转换后的文本写入Word文件即可 。
在云效中使用Java将PDF文档的内容插入到Word文档中,可以使用Apache PDFBox和Apache POI这两个开源库进行操作。
首先,需要导入以下依赖:
<dependency>
<groupId>org.apache.pdfbox</groupId>
<artifactId>pdfbox</artifactId>
<version>2.0.26</version>
</dependency>
<dependency>
<groupId>org.apache.poi</groupId>
<artifactId>poi</artifactId>
<version>5.0.0</version>
</dependency>
<dependency>
<groupId>org.apache.poi</groupId>
<artifactId>poi-ooxml</artifactId>
<version>5.0.0</version>
</dependency>
然后,可以使用以下代码将PDF文档的内容插入到Word文档中的表格:
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import org.apache.pdfbox.pdmodel.PDDocument;
import org.apache.pdfbox.text.PDFTextStripper;
import org.apache.poi.xwpf.usermodel.XWPFDocument;
import org.apache.poi.xwpf.usermodel.XWPFTable;
import org.apache.poi.xwpf.usermodel.XWPFTableRow;
import org.apache.poi.xwpf.usermodel.XWPFTableCell;
public class PDFToWord {
public static void main(String[] args) {
try {
// 加载PDF文档
PDDocument document = PDDocument.load(new FileInputStream("input.pdf"));
// 创建一个空的Word文档
XWPFDocument wordDocument = new XWPFDocument();
// 获取PDF文档的内容
PDFTextStripper stripper = new PDFTextStripper();
String pdfContent = stripper.getText(document);
// 创建一个表格
XWPFTable table = wordDocument.createTable();
// 将PDF文档的内容按行插入到表格中
String[] lines = pdfContent.split("\\r?\\n");
for (String line : lines) {
XWPFTableRow row = table.createRow();
XWPFTableCell cell = row.getCell(0);
cell.setText(line);
}
// 保存Word文档
FileOutputStream out = new FileOutputStream("output.docx");
wordDocument.write(out);
out.close();
// 关闭文档
document.close();
wordDocument.close();
System.out.println("转换完成!");
} catch (IOException e) {
e.printStackTrace();
}
}
}
上述代码中,需要将input.pdf替换为实际的PDF文件路径,转换后的Word文档将保存为output.docx。
Java SDK 使用说明:https://help.aliyun.com/document_detail/66496.html
使用 Maven 引入 SDK:
com.aliyun
aliyun-java-sdk-core
4.5.0
com.aliyun
aliyun-java-sdk-codeup
0.0.8
调用 Codeup API
以 CreateRepository 为例:
创建AK、SK见 https://usercenter.console.aliyun.com/manage/ak
创建个人访问令牌见 个人访问令牌
可以使用 Codeup Java SDK 或者阿里云 OpenAPI SDK 调用接口,区别在于使用阿里云OpenAPI SDK 需要手动设置接口信息。
使用 Codeup Java SDK
package com.alibaba.openapitest.demo;
import com.alibaba.fastjson.JSON;
import com.aliyuncs.DefaultAcsClient;
import com.aliyuncs.IAcsClient;
import com.aliyuncs.codeup.model.v20200414.CreateRepositoryRequest;
import com.aliyuncs.codeup.model.v20200414.CreateRepositoryResponse;
import com.aliyuncs.exceptions.ClientException;
import com.aliyuncs.exceptions.ServerException;
import com.aliyuncs.http.FormatType;
import com.aliyuncs.profile.DefaultProfile;
public class CreateRepository {
private String accessKeyId = "<AccessKey>";
private String accessSecret = "<AccessSecret>";
/**
* 个人访问令牌;使用AK&SK或STS 临时授权方式不传该字段
*/
private String personalAccessToken = "<PersonalAccessToken>";
private String regionId = "cn-hangzhou";
private String endPoint = "codeup.cn-hangzhou.aliyuncs.com";
/**
* 企业 ID
*/
private String organizationId = "<OrganizationId>";
public void createRepository() {
DefaultProfile profile = DefaultProfile.getProfile(regionId, accessKeyId, accessSecret);
IAcsClient client = new DefaultAcsClient(profile);
CreateRepositoryRequest request = new CreateRepositoryRequest();
request.setEndpoint(endPoint);
request.setOrganizationId(organizationId);
request.setAccessToken(personalAccessToken);
// 请求体参数,参考API文档
String body = "{\"name\": \"repoName\", \"path\": \"repoPath\", \"visibility_level\": 10, \"namespace_id\": 123}";
request.setHttpContent(JSON.toJSONString(body).getBytes(), "Utf-8", FormatType.JSON);
try {
CreateRepositoryResponse response = client.getAcsResponse(request);
logInfo(String.valueOf(response.getResult().getId()));
} catch (ServerException e) {
logInfo(String.format("Fail. Something with your connection with Aliyun go incorrect. ErrorCode: %s",
e.getErrCode()));
} catch (ClientException e) {
logInfo(String.format("Fail. Business error. ErrorCode: %s, RequestId: %s",
e.getErrCode(), e.getRequestId()));
}
}
private static void logInfo(String message) {
System.out.println(message);
}
public static void main(String[] args) {
new CreateRepository().createRepository();
}
}
使用阿里云 OpenAPI SDK
import com.aliyuncs.CommonRequest;
import com.aliyuncs.CommonResponse;
import com.aliyuncs.DefaultAcsClient;
import com.aliyuncs.IAcsClient;
import com.aliyuncs.exceptions.ClientException;
import com.aliyuncs.exceptions.ServerException;
import com.aliyuncs.http.FormatType;
import com.aliyuncs.http.MethodType;
import com.aliyuncs.profile.DefaultProfile;
/*
pom.xml
com.aliyun
aliyun-java-sdk-core
4.0.3
*/
public class CreateRepository {
public static void main(String[] args) {
DefaultProfile profile = DefaultProfile.getProfile("cn-hangzhou", "", "");
IAcsClient client = new DefaultAcsClient(profile);
CommonRequest request = new CommonRequest();
request.setProtocol(ProtocolType.HTTPS);
request.setMethod(MethodType.POST);
request.setDomain("codeup.cn-hangzhou.aliyuncs.com");
request.setVersion("2020-04-14");
request.setUriPattern("/api/v3/projects");
request.putQueryParameter("RegionId", "cn-hangzhou");
request.putQueryParameter("OrganizationId", "<OrganizationId>");
request.putHeadParameter("Content-Type", "application/json");
String requestBody = "" +
"{" +
" \"name\": \"<RepoName>\"," +
" \"path\": \"<RepoPath>\"," +
" \"visibility_level\": 10," +
" \"namespace_id\": 123" +
"}";
request.setHttpContent(requestBody.getBytes(), "utf-8", FormatType.JSON);
try {
CommonResponse response = client.getCommonResponse(request);
System.out.println(response.getData());
} catch (ServerException e) {
e.printStackTrace();
} catch (ClientException e) {
e.printStackTrace();
}
}
}
在云效中使用 Java 将 PDF 文档的内容插入到 Word 文档中,可以通过使用一些开源的 Java 库来实现。以下是一个简单的示例代码,演示了如何使用 Apache PDFBox 和 Apache POI 库来实现此功能:
import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import org.apache.pdfbox.pdmodel.PDDocument;
import org.apache.pdfbox.text.PDFTextStripper;
import org.apache.poi.xwpf.usermodel.XWPFDocument;
import org.apache.poi.xwpf.usermodel.XWPFTable;
import org.apache.poi.xwpf.usermodel.XWPFTableRow;
import org.apache.poi.xwpf.usermodel.XWPFTableCell;
public class PdfToWordConverter {
public static void main(String[] args) {
try {
// 读取 PDF 文档
PDDocument pdfDoc = PDDocument.load(new FileInputStream("input.pdf"));
// 提取 PDF 文档的文本内容
PDFTextStripper stripper = new PDFTextStripper();
String pdfContent = stripper.getText(pdfDoc);
// 创建 Word 文档
XWPFDocument wordDoc = new XWPFDocument();
XWPFTable table = wordDoc.createTable();
// 将 PDF 内容添加到 Word 表格中
String[] lines = pdfContent.split("\\r?\\n");
for (String line : lines) {
XWPFTableRow row = table.createRow();
XWPFTableCell cell = row.getCell(0);
cell.setText(line);
}
// 保存 Word 文档
FileOutputStream out = new FileOutputStream(new File("output.docx"));
wordDoc.write(out);
out.close();
// 关闭文档
pdfDoc.close();
wordDoc.close();
System.out.println("PDF 文档转换为 Word 文档成功!");
} catch (IOException e) {
e.printStackTrace();
}
}
}
你可以使用Apache POI和iText库来实现将PDF文档内容插入到Word文档中。具体步骤如下:
以下是一个简单的Java代码示例:
import java.io.*;
import java.util.List;
import org.apache.poi.xwpf.usermodel.*;
import com.itextpdf.text.pdf.*;
import com.itextpdf.text.*;
public class PdfToWord {
public static void main(String[] args) throws IOException, DocumentException {
// 读取PDF文档
PdfReader reader = new PdfReader("input.pdf");
StringWriter output = new StringWriter();
List<TextRenderInfo> textRenderInfos = PdfTextExtractor.getTextFromPage(reader, 1).get(0).getCharacterRenderInfos();
for (TextRenderInfo textRenderInfo : textRenderInfos) {
output.write(textRenderInfo.getText());
}
// 获取PDF文档中的图片
PdfDictionary pageDict = reader.getPageN(1);
PdfDictionary resourcesDict = pageDict.getAsDict(PdfName.RESOURCES);
PdfDictionary xObjectDict = resourcesDict.getAsDict(PdfName.XOBJECT);
for (PdfName name : xObjectDict.getKeys()) {
PdfObject object = xObjectDict.get(name);
if (object.isIndirect()) {
PdfDictionary xObject = (PdfDictionary) PdfReader.getPdfObject(object);
PdfName subType = (PdfName) xObject.get(PdfName.SUBTYPE);
if (subType != null && subType.equals(PdfName.IMAGE)) {
int width = xObject.getAsNumber(PdfName.WIDTH).intValue();
int height = xObject.getAsNumber(PdfName.HEIGHT).intValue();
Image image = Image.getInstance(object);
// 在Word文档中插入图片
XWPFDocument doc = new XWPFDocument();
XWPFTable table = doc.createTable();
XWPFTableRow row = table.getRow(0);
XWPFTableCell cell = row.getCell(0);
cell.addParagraph().createRun().addPicture(image.getData(), XWPFDocument.PICTURE_TYPE_PNG, "image.png", Units.toEMU(width), Units.toEMU(height));
// 保存Word文档
FileOutputStream out = new FileOutputStream("output.docx");
doc.write(out);
out.close();
}
}
}
reader.close();
}
}
需要注意的是,以上代码只是一个简单的示例,实际使用时可能需要根据实际情况进行修改和优化。

String text = pdfStripper.getText(document);
document.close();
// Create a new Word document and add a table to it
XWPFDocument wordDocument = new XWPFDocument();
XWPFTable table = wordDocument.createTable(3, 3); // Create a table with three rows and three columns
// Split the text into lines and add them to the table row by row
List<String> lines = Arrays.asList(text.split("\\r?
")); // Split the text into lines using line breaks as delimiter
for (int i = 0; i < lines.size(); i++) {
XWPFTableRow row = table.getRow(i); // Get the current row
XWPFTableCell cell = row.getCell(0); // Get the first cell in the row (column index starts from 0)
