Excel表格导入导出springcloudalibaba+vue+elmentUi
这个问题看起来有些广泛,我会提供一个简化版的解决方案,主要是展示如何在Spring Cloud Alibaba、Vue和Element UI环境下实现Excel文件的导入和导出。
后端(Spring Cloud Alibaba):
使用easyexcel
库来处理Excel文件的导入和导出。
导入:
@PostMapping("/import")
public R<?> importExcel(@RequestParam("file") MultipartFile file) {
List<MyDataModel> dataList = EasyExcel.read(file.getInputStream())
.head(MyDataModel.class)
.sheet()
.doReadSync();
// 业务处理逻辑
return R.ok("导入成功");
}
导出:
@GetMapping("/export")
public void exportExcel(HttpServletResponse response) throws IOException {
List<MyDataModel> dataList = ...; // 业务数据获取逻辑
String fileName = "exported_data.xlsx";
response.setContentType("application/vnd.ms-excel");
response.setCharacterEncoding("utf-8");
response.setHeader("Content-disposition", "attachment;filename=" + URLEncoder.encode(fileName, "UTF-8").replaceAll("\\+", "%20"));
EasyExcel.write(response.getOutputStream(), MyDataModel.class)
.sheet("Sheet1")
.doWrite(dataList);
}
前端(Vue + Element UI):
使用Element UI的<el-upload>
组件实现文件上传,并使用Axios发送请求到后端。
<template>
<el-upload
action="http://your-backend-service/import"
:on-success="handleImportSuccess"
:on-error="handleImportError">
<el-button slot="trigger" size="small" type="primary">选择文件</el-button>
<el-button size="small" type="success" @click="submitUpload">上传到服务器</el-button>
</el-upload>
</template>
<script>
export default {
methods: {
handleImportSuccess(response, file, fileList) {
console.log('Import successful', response);
},
handleImportError(err, file, fileList) {
console.error('Import failed', err);
},
submitUpload() {
this.$refs.upload.submit();
}
}
}
</script>
导出按钮:
<template>
<el-button size="small" type="warning" @click="exportData">导出数据</el-button>
</template>
<script>
export default {
methods: {
exportData() {
window.location.href = 'http://your-backend-service/export';
}
}
}
</script>
请注意,这些代码示例需要根据你的具体需求进行调整,比如数据模型MyDataModel
、服务URL和业务逻辑等。同时,你需要配置Spring Cloud Alibaba的后端服务,以允许跨域请求和文件上传大小的配置。
