虽然浪费的时间有点多，不过磨刀不误砍柴工
前置条件
- 后台springboot基础项目
- vue基础项目
⭐ 如没有基础代码可以直接下载狗哥Gitee源码
步骤解析
后台
1.下载对应的aspose-words-19.1-jdk16.jar，加入POM本地依赖
因原版收费且会有水印等不确定因素，直接下载jar包本地依赖或者上传私服
<!-- 本地依赖 aspose-words-->
<dependency>
<groupId>com.aspose</groupId>
<artifactId>aspose-words</artifactId>
<classifier>jdk16</classifier>
<scope>system</scope>
<version>1.0</version>
<systemPath>${project.basedir}/src/main/resources/lib/aspose-words-19.1-jdk16.jar</systemPath>
</dependency>2.放置模板文件到资源路径下
3.controller读取模板文件并填充数据
- 读取模板并将输入流转为doc,并设置文件名及返回类型
- 定位【照片】书签位置，插入图片
- 定位【等级】书签位置，插入对应字符
书签插入参考如下
- 找到需要插入的图片的地方，鼠标焦点聚焦
- 点击【插入】找到书签并点击,然后录入书签名，并点击添加
检查书签是否添加成功
更新doc
- 将基础数据填充后并转为PDF
详见如下代码
package apose.javadog.net.controller; import apose.javadog.net.entity.BaseInfo; import apose.javadog.net.entity.Education; import apose.javadog.net.entity.Interview; import apose.javadog.net.entity.WorkExperience; import cn.hutool.core.util.CharsetUtil; import com.aspose.words.Document; import com.aspose.words.DocumentBuilder; import com.aspose.words.ReportingEngine; import com.aspose.words.SaveFormat; import lombok.extern.slf4j.Slf4j; import org.springframework.core.io.ClassPathResource; 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.InputStream; import java.net.URLEncoder; import java.util.ArrayList; import java.util.List; @RestController @RequestMapping("/word") @Slf4j public class WordController { @GetMapping("/pdf") void pdf(HttpServletResponse response){ // 获取资源doc路径下的简历interview.doc模板 final ClassPathResource classPathResource = new ClassPathResource("doc\\interview.doc"); // 组装数据 final Document doc; try (InputStream inputStream = classPathResource.getInputStream(); ServletOutputStream outputStream = response.getOutputStream()) { // 文件名称 String fileName = URLEncoder.encode("帅锅的简历.pdf", CharsetUtil.UTF_8); response.reset(); response.setHeader("Content-Disposition", "attachment; filename=\"" + fileName + "\""); response.setHeader("Access-Control-Allow-Origin", "*"); response.setContentType("application/octet-stream;charset=UTF-8"); // 将输入流转为doc doc = new Document(inputStream); // doc构建 DocumentBuilder builder = new DocumentBuilder(doc); // 定位书签位置 builder.moveToBookmark("AVATAR"); // 插入图片 builder.insertImage("https://portrait.gitee.com/uploads/avatars/user/491/1474070_javadog-net_1616995139.png!avatar30"); // 定位LANGUAGE_LEVEL4书签位置 builder.moveToBookmark("LANGUAGE_LEVEL4"); // 设置字符名称 builder.getFont().setName("Wingdings"); // 设置字符大小 builder.getFont().setSize(14); // 对号字符 builder.write("\uF0FE"); // 定位LANGUAGE_LEVEL6书签位置 builder.moveToBookmark("LANGUAGE_LEVEL6"); // 设置字符名称 builder.getFont().setName("Wingdings"); builder.getFont().setSize(20); builder.write("□"); doc.updateFields(); final ReportingEngine engine = new ReportingEngine(); // 将数据填充至模板 engine.buildReport(doc, getInterviewData(), "data"); // 转pdf doc.save(outputStream, SaveFormat.PDF); } catch (Exception e) { log.error("生成报告异常，异常信息：{}", e.getMessage(), e); e.printStackTrace(); } } private Interview getInterviewData(){ Interview interview = new Interview(); this.getBaseInfo(interview); this.getEducations(interview); this.getWorkExperiences(interview); return interview; } /** * @Description: 组装基本数据 * @Param: [interview] * @return: [apose.javadog.net.entity.Interview] * @Author: hdx * @Date: 2022/5/10 15:39 */ private void getBaseInfo(Interview interview){ // 基本数据 BaseInfo baseInfo = new BaseInfo(); List<String> listStr = new ArrayList<>(); listStr.add("后端技术栈：有较好的Java基础，熟悉SpringBoot,SpringCloud,springCloud Alibaba等主流技术，Redis内存数据库、RocketMq、dubbo等，熟悉JUC多线程"); listStr.add("后端模板引擎：thymeleaf、volocity"); listStr.add("前端技术栈：熟练掌握ES5/ES6/、NodeJs、Vue、React、Webpack、gulp"); listStr.add("其他技术栈: 熟悉python+selenium、electron"); baseInfo.setName("狗哥") .setBirth("1993年5月14日") .setHeight("180") .setWeight("70") .setNation("汉") .setSex("男") .setNativePlace("济南") .setMarriage("已婚") .setSpecialtys(listStr); interview.setBaseInfo(baseInfo); } /** * @Description: 组装教育经历 * @Param: [interview] * @return: [apose.javadog.net.entity.Interview] * @Author: hdx * @Date: 2022/5/10 15:40 */ private void getEducations(Interview interview){ // 高中 List<Education> educations = new ArrayList<>(); Education education = new Education(); education.setStartEndTime("2009-2012") .setSchool("山东省实验中学") .setFullTime("是") .setProfessional("理科") .setEducationalForm("普高"); educations.add(education); // 大学 Education educationUniversity = new Education(); educationUniversity.setStartEndTime("2012-2016") .setSchool("青岛农业大学") .setFullTime("是") .setProfessional("计算机科学与技术") .setEducationalForm("本科"); educations.add(educationUniversity); interview.setEducations(educations); } /** * @Description: 组装工作经历 * @Param: [interview] * @return: [apose.javadog.net.entity.Interview] * @Author: hdx * @Date: 2022/5/10 15:40 */ private void getWorkExperiences(Interview interview){ // 工作记录 List<WorkExperience> workExperiences = new ArrayList<>(); WorkExperience workExperience = new WorkExperience(); workExperience.setStartEndTime("2009-2012") .setWorkUnit("青岛XXX") .setPosition("开发") .setResignation("有更好的学习空间，向医疗领域拓展学习纬度"); workExperiences.add(workExperience); interview.setWorkExperiences(workExperiences); } }
前端
1.下载对应的依赖包
npm install
2.在vue.config.js中配置代理
const { defineConfig } = require('@vue/cli-service')
module.exports = defineConfig({
devServer: {
port: 1026,
proxy: {
'/': {
target: 'http://localhost:8082', //请求本地 需要ipps-boot后台项目
ws: false,
changeOrigin: true
}
}
}
})npm install
3.在main.js引入所需插件
import Vue from 'vue'
import App from './App.vue'
Vue.config.productionTip = false
import axios from 'axios'
Vue.prototype.$http = axios
import ElementUI from 'element-ui';
import 'element-ui/lib/theme-chalk/index.css';
Vue.use(ElementUI);
new Vue({
render: h => h(App),
}).$mount('#app')4.页面引入vue-pdf组件
<pdf v-if="showPdf" ref="pdf" :src="pdfUrl" :page="currentPage" @num-pages="pageCount=$event"
@page-loaded="currentPage=$event" @loaded="loadPdfHandler">
</pdf>5.页面中使用axios调取接口获取数据
👽注意responseType类型为blob
this.$http({
method: 'get',
url: `/word/pdf`,
responseType: 'blob'
}).then(res=>{
console.log(res)
this.pdfUrl = this.getObjectURL(res.data)
console.log(this.pdfUrl)
const loadingTask = pdf.createLoadingTask(this.pdfUrl)
// // 注意这里一定要这样写
loadingTask.promise.then(load => {
this.numberPage = load.numPages
}).catch(err => {
console.log(err)
})
this.loading = false;
})页面完整代码如下
<template>
<div class="pdf_wrap">
<template>
<el-form ref="form" label-width="80px">
<div style='text-align: center;margin: 30px;' v-if="loading">
数据加载中...
</div>
<div v-if="loading==false" style="display: flex;align-items: center;">
<div style="flex: 1;"></div>
<el-button size="mini" @click="changePdfPage(0)" type="primary">上一页</el-button>
<div style="position: relative; margin: 0px 10px; top: -10px;">
{{currentPage}} / {{pageCount}} 共 {{numberPage}} 页
</div>
<el-button size="mini" @click="changePdfPage(1)" type="primary">下一页</el-button>
<el-button size="mini" @click='print' type="primary">打印</el-button>
</div>
<div v-show="loading==false">
<pdf v-if="showPdf" ref="pdf" :src="pdfUrl" :page="currentPage" @num-pages="pageCount=$event"
@page-loaded="currentPage=$event" @loaded="loadPdfHandler">
