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

1. 读取模板并将输入流转为doc,并设置文件名及返回类型
   
2. 定位【照片】书签位置，插入图片
   
3. 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

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">
          </pdf>
        </div>
      </el-form>
    </template>
  </div>

异常情况

1.vue-pdf原版与webpack版本问题，会启动不起来，所以本狗才偷梁换柱，改了一下并自用

2.aspose-words-19.1-jdk16.jar 如果采用官网的maven依赖，可能需要自助破解或交费使用
