Java實現(xiàn)讀取Excel數(shù)據(jù)并寫入到Word
更新時間：2025年07月09日 09:26:25 作者：極客星云
這篇文章主要為大家詳細(xì)介紹了如何使用Java實現(xiàn)讀取Excel數(shù)據(jù)并寫入到Word功能,文中的示例代碼講解詳細(xì),感興趣的小伙伴可以跟隨小編一起學(xué)習(xí)一下
讀取Excel 數(shù)據(jù)并寫入到Word
我們知道操作office 文檔一般常用的就是Apache POI 以及Easy POI.
Apache POI 是對office 早期的版本 .doc ,.xls 以及后期的*.docx 和*.xlsx API 的實現(xiàn)。
關(guān)于EasyPOI 據(jù)說是對Apache POI做了更好的封裝和功能擴(kuò)展，讓開發(fā)變得更加簡單。
好了廢話不多說，本篇博文將使用Apache POI 來讀取Excel 數(shù)據(jù)并寫入到word 文檔中。
最終效果如圖所示：
配置pom.xml
pom.xml 添加依賴如下:

配置 application.properties
application.properties
spring.profiles.active=dev
application-dev.properties
spring.application.name=transport-excel-data-to-word server.address=127.0.0.1 server.port=8080 server.servlet.context-path=/ spring.thymeleaf.prefix=classpath:/templates/bootstrap-ui-framework/ spring.thymeleaf.suffix=.html spring.thymeleaf.encoding=UTF-8 # 上次文件配置 com.xingyun.customize.upload-folder=C:/opt/upload # Servlet配置 # 連接超時設(shè)置為最大值 server.connection-timeout=999999999 spring.servlet.multipart.max-file-size=4096GB spring.servlet.multipart.max-request-size=4096GB spring.servlet.multipart.enabled=true # Tomcat配置 # 解決大文件上傳問題 # Tomcat針對中止上載將吞下的最大請求正文字節(jié)數(shù)（不包括傳輸編碼開銷） #中止上傳是指Tomcat知道請求體將被忽略但客戶端仍然發(fā)送它 # 如果Tomcat沒有吞下身體，則客戶端不太可能看到響應(yīng) # 如果未指定，將使用默認(rèn)值2097152（2兆字節(jié)） # 值小于零表示不應(yīng)強(qiáng)制執(zhí)行限制 server.tomcat.max-swallow-size=-1 server.tomcat.max-connections=10000 server.tomcat.max-http-post-size=4096GB
自定義配置屬性
由于上面com.xingyun.customize.upload-folder=C:/opt/upload
我們使用了一些自定義配置，因此按照最佳實踐來做，需要做點代碼配置支持。
創(chuàng)建一個Java Config 類，并激活配置屬性文件。
import com.xingyun.transportexceldatatoword.customize.SmartUploadProperties;
import org.springframework.boot.context.properties.EnableConfigurationProperties;
import org.springframework.context.annotation.Configuration;
/**
* @author 星云
* @功能
* @date 10/13/2019 12:00 PM
*/
@EnableConfigurationProperties({
SmartUploadProperties.class
})
@Configuration
public class CustomizePropertiesConfig {
}
然后創(chuàng)建一個自定義配置類
import lombok.Getter;
import lombok.Setter;
import lombok.ToString;
import org.springframework.boot.context.properties.ConfigurationProperties;
/**
* @author 星云
* @功能
* @date 10/13/2019 12:01 PM
*/
@Getter
@Setter
@ToString
@ConfigurationProperties(prefix="com.xingyun.customize")
public class SmartUploadProperties {
/**
* 注意"這里的變量名稱不可以有下劃線 否則會出錯
*/
private String uploadFolder;
}
注意：
這樣配置后，映射到配置文件就是
com.xingyun.customize.upload-folder=C:/opt/upload
配置首頁請求攔截并初始化文件夾
代碼如下:
import com.xingyun.transportexceldatatoword.customize.SmartUploadProperties;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
import java.io.File;
/**
* @author 星云
* @功能
* @date 10/13/2019 9:34 AM
*/
@Controller
public class HomePageController {
@Autowired
SmartUploadProperties smartUploadProperties;
@GetMapping(value = "/")
public String homePage(){
File file=new File(smartUploadProperties.getUploadFolder());
if(!file.exists()){
file.mkdirs();
}
return "index";
}
}
注意：這樣當(dāng)訪問首頁的時候就會初始化上傳文件夾了
配置上傳頁面
然后我們需要一個上傳頁面，編寫代碼如下:
<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.thymeleaf.org">
<head>
<!-- Required meta tags -->
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">
<link rel="stylesheet" th:href="@{../static/third-party/bootstrap-4.3.1-dist/css/bootstrap.min.css}" rel="external nofollow" >
<title>Excel Data To Word App</title>
</head>
<body>
<div align="center">
<h1>Excel Data To World App</h1>
</div>
<div class="jumbotron text-center">
<div align="left">
<form action="/upload.do" enctype="multipart/form-data" method="post">
<input th:type="file" name="uploadFileName" >
<input type="submit" value="提交">
</form>
</div>
</div>
<!-- Optional JavaScript -->
<!-- jQuery first, then Popper.js, then Bootstrap JS -->
<script th:src="@{../static/third-party/jquery/jquery-3.3.1.slim.min.js}"></script>
<script th:src="@{../static/third-party/ajax/libs/popper.js/1.14.7/umd/popper.min.js}"/>
<script th:src="@{../static/third-party/bootstrap-4.3.1-dist/js/bootstrap.min.js}"/>
</body>
</html>
上傳文件
處理文件上傳的控制器編寫如下:
import com.xingyun.transportexceldatatoword.constant.CommonConstant;
import com.xingyun.transportexceldatatoword.customize.SmartUploadProperties;
import com.xingyun.transportexceldatatoword.util.SmartPoiExcelUtils;
import com.xingyun.transportexceldatatoword.util.SmartPoiWordUtils;
import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.multipart.MultipartFile;
import javax.servlet.http.HttpServletResponse;
import java.io.File;
import java.io.IOException;
import java.util.List;
/**
* @author 星云
* @功能
* @date 10/13/2019 9:43 AM
*/
@Slf4j
@Controller
public class UploadApiController {
@Autowired
SmartUploadProperties smartUploadProperties;
@PostMapping(value = "/upload.do")
public String upload(@RequestParam(value = "uploadFileName") MultipartFile multipartFile, HttpServletResponse response){
log.info(multipartFile.getOriginalFilename());
//構(gòu)建保存文件路徑
StringBuilder stringBuilder=new StringBuilder();
stringBuilder.append(smartUploadProperties.getUploadFolder());
stringBuilder.append(File.separator);
stringBuilder.append(multipartFile.getOriginalFilename());
//上傳文件路徑
String uploadFilePath=stringBuilder.toString();
//文件
File file=new File(uploadFilePath);
try {
//將上傳的文件保存下來
multipartFile.transferTo(file);
} catch (IOException e) {
log.error(e.getMessage(),e);
}
//將Excel中的數(shù)據(jù)進(jìn)行解析成對象
List<String> dataList= SmartPoiExcelUtils.parseExcelData(file.getAbsolutePath());
//生成World 的文件路徑
StringBuilder worldName=new StringBuilder();
worldName.append(smartUploadProperties.getUploadFolder());
worldName.append(File.separator);
worldName.append("data.docx");
//將數(shù)據(jù)寫入到文檔中
try {
SmartPoiWordUtils.writeDataToWord(worldName.toString(),dataList);
} catch (IOException e) {
log.error("IO Exception:",e);
}
//寫入完成后放入這個列表中
CommonConstant.shareFileMap.put("downloadFile",worldName.toString());
return "redirect:/api/v1/download.do";
}
}
這里使用了兩個工具類，將上傳的excel 文件保存到指定的路徑，然后將內(nèi)容寫入到word中，最后重定向到一個處理文件下載的控制器中。
