easypoi封装了poi让我们能够非常简单的实现Excel导出,Excel模板导出,Excel导入,Word模板导出等，具体可见官网：http://www.afterturn.cn/。
我这边实现了一个excel的导出，记录一下。
1、pom文件引入starter
<dependency> <groupId>cn.afterturn</groupId> <artifactId>easypoi-spring-boot-starter</artifactId> <version>3.2.0</version> </dependency>
2、定义需要导出的对象DTO
@Table(name = "ORDERS") public class OrderExcelDto{ @Excel(name = "ORDER_ID", width = 25,orderNum = "0") private String orderId; @Excel(name = "CREATE_TIME",width = 20,exportFormat = "yyyy-MM-dd HH:mm:ss", orderNum = "1") private Date createTime; @Excel(name = "STATUS",width = 20,replace = {"created_01", "payment_02","used_03","time out_04"}, orderNum = "2") private String status; public String getOrderId() { return orderId; } public void setOrderId(String orderId) { this.orderId = orderId; } public Date getCreateTime() { return createTime; } public void setCreateTime(Date createTime) { this.createTime = createTime; } public String getStatus() { return status; } public void setStatus(String status) { this.status = status; } }
具体语义如下，详情可见官网
name：列明；replace：前者是最后替换的值，后者是数据库的值；exportFormat：导出的时间格式,以这个是否为空来判断是否需要格式化日期；width：列宽等
3、将查询的sql映射到上述的DTO，然后通过starter中提供工具类做导出操作
@GetMapping("/orderExport") public void orderExport(HttpServletResponse response) throws Exception { response.setHeader("content-Type", "application/vnd.ms-excel"); response.setHeader("Content-Disposition", "attachment;filename=orders.xls"); List<OrderExcelDto> list = orderService.queryOrderExcel(); Workbook workbook = ExcelExportUtil.exportExcel(new ExportParams(),OrderExcelDto.class,list); workbook.write(response.getOutputStream()); }
4、前台js中可以直接定义事件触发上述get请求
function export() { document.location.href = host+"/orderExport"; }
最后就可以验证一下了，如果有问题可以邮件我。
spring boot + easypoi两行代码excel导入导出
