### 前言
#### ⏲️本文阅读时长：约10分钟
#### 🎯主要目标：
##### 1.实现Springboot与aspose-words整合，填充word模板并转化PDF;
##### 2.前端vue整合vue-pdf实现PDF预览及下载
#### word模板重点(详见图示)
##### 1.单属性赋值
##### 2.List循环赋值
##### 3.图片插入
##### 4.对勾特殊符号插入

#### 模板填充前空word模板
![我还是没有放下你](https://img.javadog.net/blog/boot-apose/3b073c52d76a4e22bf387097930ab37a_tplv-k3u1fbpfcp-zoom-1.png)
#### 代码填充后word模板

#### web端vue预览的html的pdf
![](https://img.javadog.net/blog/boot-apose/38ca3cfa035644f18ba78c32594de775_tplv-k3u1fbpfcp-zoom-1.png)

#### 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](https://gitee.com/javadog-net/boot-apose.git)

#### 步骤解析
##### 后台
###### 1.下载对应的[aspose-words-19.1-jdk16.jar](https://download.csdn.net/download/baidu_25986059/85390408)，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
>

```xml
 
        <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
![](https://img.javadog.net/blog/boot-apose/5542432dbdd34b16a590c6bdfcc94162_tplv-k3u1fbpfcp-zoom-1.png)

###### 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
![](https://img.javadog.net/blog/boot-apose/cfc2569f87de41ac8d560d41fb79a104_tplv-k3u1fbpfcp-zoom-1.png)
 2. 定位【照片】书签位置，插入图片
![](https://img.javadog.net/blog/boot-apose/b7331f8344084209ba998cd89715c1da_tplv-k3u1fbpfcp-zoom-1.png)
 3. 定位【等级】书签位置，插入对应字符
![](https://img.javadog.net/blog/boot-apose/7e7325aa214e43798ae5c42d410834be_tplv-k3u1fbpfcp-zoom-1.png)
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
![](https://img.javadog.net/blog/boot-apose/590aa9ef106e445ca4182bff578528fb_tplv-k3u1fbpfcp-zoom-1.png)

-  点击【插入】找到书签并点击,然后录入书签名，并点击添加
![](https://img.javadog.net/blog/boot-apose/9fe6ac4ed92c4c63a97c6feaedb37bbf_tplv-k3u1fbpfcp-zoom-1.png)
-  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

```

##### 前端
###### 1.下载对应的依赖包
> npm install
###### 2.在vue.config.js中配置代理
```js
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
```js
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
```html
  <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**
```js
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

```html
<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>
</template>

### 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
### 成果展示
