java导出word套打
这篇文档手把手教你完成导出word套打，有这个demo，其他word套打导出都通用。
1、主要依赖
cn.hutool
hutool-all
5.3.0
cn.hutool
hutool-core
5.3.0
org.apache.poi
poi-ooxml
4.1.2
repository.org.projectlombok
lombok
1.16.22
repository.org.apache.commons
commons-lang3
3.9
2、模板excel见附件。
3、以下为导出代码逻辑：
package com.example.demo.excel;
import cn.hutool.poi.word.PicType;
import lombok.Data;
/**
* 图片对象
* @author xiajun
*/
@Data
public class WordImage {
/**
* 图片宽度
*/
private int width = 100;
/**
* 图片高度
*/
private int height = 100;
/**
* 图片地址
* resource资源相对路径
*/
private String path;
/**
* 字节流
*/
private byte[] source;
/**
* 图片类型
* 默认PNG
*
*/
private PicType imageType = PicType.PNG;
}
package com.example.demo.excel;
import cn.hutool.core.collection.CollectionUtil;
import cn.hutool.core.io.FileUtil;
import cn.hutool.poi.word.Word07Writer;
import cn.hutool.poi.word.WordUtil;
import lombok.extern.slf4j.Slf4j;
import org.apache.poi.xwpf.usermodel.*;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import javax.servlet.ServletOutputStream;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.util.*;
/**

@Slf4j
@RestController
@RequestMapping("mvc/word")
public class WordExport {
@GetMapping(path = "/export")
public void export(HttpServletResponse response) throws IOException {
//1、============================模拟数据===============================
Map params = new HashMap<>();
params.put("${name}", "张三");
params.put("${sex}", "男");
params.put("${birth}", "1999.11");
params.put("${age}", "25");
params.put("${nation}", "汉族");
params.put("${npn}", "四川成都");
params.put("${bpn}", "四川成都");
params.put("${pt}", "2017.02");
params.put("${workTime}", "2016.03");
params.put("${hn}", "健康");
params.put("${beFawts}", "打篮球");
params.put("${proTec}", "高级工程师");
params.put("${degree}", "大学本科");
params.put("${education}", "文学学士");
params.put("${school}", "北京大学文院");
params.put("${major}", "语言学");
params.put("${dutyDegree}", "研究生毕业");
params.put("${dutyEducation}", "其他");
params.put("${dutySchool}", "四川大学土木学院");
params.put("${dutyMajor}", "工程造价");
params.put("${jobName}", "党委书记,组织部长,宣传部部长");
//图片设置
WordImage wordImage = new WordImage();
wordImage.setHeight(150);
wordImage.setWidth(100);
byte[] imageBytes = FileUtil.readBytes("templates/fm.png");
wordImage.setSource(imageBytes);
params.put("@{photo}", wordImage);
//一段长文本拆分，按照分行进行展示，例如简历这种
String resume = "2017.08--2018.08 北京大学光华管理学院工商管理就读研究生\r2023.05--2023.09 简历测试职务\r2023.05--2023.09 外部人员挂职职务\r2023.09-- 图书档案资料人员";
params.put("${resume}", resume);
//2、============================获取word模板===============================
Word07Writer writer = WordUtil.getWriter(FileUtil.file("templates/mb.docx"));
XWPFDocument document = writer.getDoc();//获取模板文档
//3、============================获取模板文本的段落===============================
Iterator paragraphStrings = document.getParagraphsIterator();
while (paragraphStrings.hasNext()) {
XWPFParagraph paragraph = paragraphStrings.next();
log.info("文本段落文字：{}", paragraph.getText());
}
//4、============================获取模板表格的段落===============================
Iterator tableIterator = document.getTablesIterator();
while (tableIterator.hasNext()) {
XWPFTable table = tableIterator.next();
Iterator rows = table.getRows().listIterator();
while (rows.hasNext()) {
XWPFTableRow row = rows.next();
Iterator cells = row.getTableCells().listIterator();
while (cells.hasNext()) {
XWPFTableCell cell = cells.next();
List paragraphCells = cell.getParagraphs();
//只去表格中的一个段落
XWPFParagraph paragraph = CollectionUtil.isNotEmpty(paragraphCells) ? paragraphCells.get(0) : null;
if(paragraph != null){
String paragraphString = paragraph.getText();//段落中的文字
//占位符替换
TemplateProcessor.matchTemplate(paragraphString, params, paragraph);
}
}
}
}
//5、======================输出文件====================================
// 设置content—type
response.setContentType("application/vnd.openxmlformats-officedocument.spreadsheetml.sheet;charset:utf-8");
response.setHeader("Content-Disposition", "attachment;filename=data.docx");
// 设置标题
//Content-disposition是MIME协议的扩展，MIME协议指示MIME用户代理如何显示附加的文件。
ServletOutputStream outputStream = response.getOutputStream();
//将Writer刷新到OutPut
writer.flush(outputStream, true);
outputStream.close();
}

4、导出效果：
注意事项：如果你调整了代码设置数据，但是没生效，把target目录下的class文件删除重启哈就生效了。
