JeecgBoot通过EasyExcel导出自定义报表

JeecgBoot通过EasyExcel导出自定义报表

一、作用

根据自己自定义模板，导出主附表数据的报表

二、示例图

1、目前只学习做过自定义excel格式的报表
2、后期学会其他格式的报表，再讲其他的

三、后台代码

1、实体类

@Data
public class OrderVo {
	/**主键*/
	@TableId(type = IdType.ASSIGN_ID)
    @ApiModelProperty(value = "主键")
    private String id;
	
    /**客户*/
    @ExcelProperty("客户")
    @ApiModelProperty(value = "客户")
    private String name;
    
    @ExcelProperty("手机号")
    @ApiModelProperty(value = "手机号")
    private String phine;
    
    @ExcelProperty("地址")
    @ApiModelProperty(value = "地址")
    private String address;
    
    @ExcelProperty("年龄")
    @ApiModelProperty(value = "年龄")
    private int age;
    
    @ExcelProperty("服务名称")
    @ApiModelProperty(value = "服务名称")
    private String serviceName;
   
    @ExcelProperty("服务价格")
    @ApiModelProperty(value = "服务价格")
    private java.math.BigDecimal servicePrice;

    @ExcelProperty(value = "章子图片")
    @ApiModelProperty(value = "章子图片")
    private File file;

    @ExcelProperty("总计")
    @ApiModelProperty(value = "总计")
    private java.math.BigDecimal zongji;
}

2、服务项目明细实体类

public class OrderDetail implements Serializable {
    private static final long serialVersionUID = 1L;

	/**主键*/
	@TableId(type = IdType.ASSIGN_ID)
    @ApiModelProperty(value = "主键")
    private String id;
    
	/**订单id*/
    @ApiModelProperty(value = "订单id")
    private String orderId;
    
	/**名称*/
	@ExcelProperty("名称")
	@Excel(name = "名称", width = 15)
    @ApiModelProperty(value = "名称")
    private String name;
    
	/**时间*/
    @ExcelProperty("时间")
	@Excel(name = "时间", width = 15)
    @ApiModelProperty(value = "时间")
    private java.lang.String time;

	/**数量*/
    @ExcelProperty("数量")
	@Excel(name = "数量", width = 15)
    @ApiModelProperty(value = "数量")
    private java.math.BigDecima num;
    
	/**单价*/
    @ExcelProperty("单价")
	@Excel(name = "单价", width = 15)
    @ApiModelProperty(value = "单价")
    private java.math.BigDecimal price;
    
	/**总价*/
    @ExcelProperty("总价")
	@Excel(name = "总价", width = 15)
    @ApiModelProperty(value = "总价")
    private java.math.BigDecimal sumPrice;

    /**序号*/
    @TableField(exist = false)
    private Integer row;
}

3、controller方法

public void exportOrder(HttpServletResponse response, String orderId) throws IOException {
		//赋值
		OrderVo orderVo = new OrderVo();
		orderVo.setName("张三");
		orderVo.setPhone("181111111111");
		//设置图片
		exportOrder.setFile(new File(exportPath+"tc.png"));

		//获取模板路径
		String templateFile = exportPath+"模板名.xlsx";
	
		//查询数据
		 List detailList = OrderDetailService.list(
				 new QueryWrapper().lambda().eq(OrderDetail::getOrderId, orderId));
		
		//序号
		int i = 0;
		for(AtbOfferOrderDetail detail : orderDetailList){
			i+=1;
		 	detail.setRow(i);
		 }
		 
		 try {
			 response.setContentType("application/vnd.ms-excel");
			 response.setCharacterEncoding("utf-8");
			 String outFileName ="合同单【"+ orderVo .getId() +"】";
			 
			 //填写合同单号和模板， getOutputStream浏览器下载方法写在下方
			 ExcelWriter excelWriter = EasyExcel.write(this.getOutputStream(outFileName, response)).withTemplate(templateFile).build();
			 WriteSheet writeSheet = EasyExcel.writerSheet(0,"第一个").build();

			 // 组合填充时，因为多组填充的数据量不确定，需要在多组填充完之后另起一行
			 FillConfig fillConfig = FillConfig.builder().direction(WriteDirectionEnum.VERTICAL).forceNewRow(Boolean.TRUE).build();
			 excelWriter.fill(new FillWrapper(orderDetailList), fillConfig, writeSheet);
			 excelWriter.fill(exportOrder, writeSheet);
			 excelWriter.finish();

		 } catch (Exception e) {
			 System.out.println(e.toString());
			 response.reset();
			 response.setContentType("application/json");
			 response.setCharacterEncoding("utf-8");
			 Map map = new HashMap(16);
			 map.put("status", "failure");
			 map.put("message", "下载文件失败" + e.getMessage());
			 response.getWriter().println(JSON.toJSONString(map));
		 }

	 }

2、getOutputStream浏览器下载方法

/**
	  * 这是ExcelUtil.getOutputStream
	  * 这里就是将文件下载交给了浏览器
	  * @param
	  * @return
	  */
	 public OutputStream getOutputStream(String fileName, HttpServletResponse response) throws Exception {
		 // 这里文件名如果涉及中文一定要使用URL编码,否则会乱码
		 String exportFileName = URLEncoder.encode(fileName+ExcelTypeEnum.XLSX.getValue(), StandardCharsets.UTF_8.toString());
		 response.setContentType("application/force-download");
		 response.setHeader("Content-Disposition", "attachment;filename=" + exportFileName);
		 return response.getOutputStream();
	 }
