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

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">

</div>
</el-form>

if (val === 0 && this.currentPage > 1) {
this.currentPage--
// console.log(this.currentPage)
}
if (val === 1 && this.currentPage < this.pageCount) {
this.currentPage++
// console.log(this.currentPage)
}
},
// pdf加载时
loadPdfHandler() {
console.log('jiazai')
this.currentPage = 1 // 加载的时候先加载第一页
this.loading = false;
}
}
}
</script>

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
