@Excel(name = "发货批次单号", orderNum = "1")

这是Java中的一个注解,具体来说是用于Excel导出功能的。其中name属性表示在生成的Excel文件中该字段的列名为“发货批次单号”,orderNum属性则表示该字段在Excel表格中的顺序为第一列。通常情况下,我们可以通过在Java实体类的字段上添加@Excel注解来指定该字段需要被导出到Excel文件中。
需要注意的是,这个注解可能并不是Java语言本身提供的标准注解,而是某些框架或者工具库自定义的注解。如果您想要使用这个注解,需要先引入相应的依赖,并且了解其具体的使用方法和限制条件。

给以下代码的@Excel里添加orderNum属性,并赋值,值为字符号数字,且从10开始递增:@Excel(name = "负荷率",groupName = "萨南深冷",fixedIndex = 10) private String snslfhl; @Excel(name = "外输气阀组压力",groupName = "萨南深冷",fixedIndex = 11) private String snslwsqfyl; @Excel(name = "外输轻烃量",groupName = "萨南深冷",fixedIndex = 12) private String snslwsqtl; @Excel(name = "返输轻烃量",groupName = "萨南深冷",fixedIndex = 13) private String snslfsqtl; @Excel(name = "水消耗",groupName = "萨南深冷",fixedIndex = 14) private String snslsxh; @Excel(name = "电消耗",groupName = "萨南深冷",fixedIndex = 15) private String snsldxh; @Excel(name = "醇消耗",groupName = "萨南深冷",fixedIndex = 16) private String snslcxh; @Excel(name = "气消耗",groupName = "萨南深冷",fixedIndex = 17) private String snslqxh; @Excel(name = "加热炉燃料气",groupName = "萨南深冷",fixedIndex = 18) private String snsljrl; @Excel(name = "收烃率",groupName = "萨南深冷",fixedIndex = 19) private String snslstl; @Excel(name = "锅炉燃料气",groupName = "萨南深冷",fixedIndex = 20) private String snslglyql;
可以将`@Excel`注解中添加一个`orderNum`属性,并给定初始值为10,然后在每个注解上递增即可。修改后的代码如下:
```
@Excel(name = "负荷率", groupName = "萨南深冷", fixedIndex = 10, orderNum = "10")
private String snslfhl;
@Excel(name = "外输气阀组压力", groupName = "萨南深冷", fixedIndex = 11, orderNum = "11")
private String snslwsqfyl;
@Excel(name = "外输轻烃量", groupName = "萨南深冷", fixedIndex = 12, orderNum = "12")
private String snslwsqtl;
@Excel(name = "返输轻烃量", groupName = "萨南深冷", fixedIndex = 13, orderNum = "13")
private String snslfsqtl;
@Excel(name = "水消耗", groupName = "萨南深冷", fixedIndex = 14, orderNum = "14")
private String snslsxh;
@Excel(name = "电消耗", groupName = "萨南深冷", fixedIndex = 15, orderNum = "15")
private String snsldxh;
@Excel(name = "醇消耗", groupName = "萨南深冷", fixedIndex = 16, orderNum = "16")
private String snslcxh;
@Excel(name = "气消耗", groupName = "萨南深冷", fixedIndex = 17, orderNum = "17")
private String snslqxh;
@Excel(name = "加热炉燃料气", groupName = "萨南深冷", fixedIndex = 18, orderNum = "18")
private String snsljrl;
@Excel(name = "收烃率", groupName = "萨南深冷", fixedIndex = 19, orderNum = "19")
private String snslstl;
@Excel(name = "锅炉燃料气", groupName = "萨南深冷", fixedIndex = 20, orderNum = "20")
private String snslglyql;
```
这样每个属性的`orderNum`就会依次递增。
package com.zs.create.modules.socialrecord.entity; import com.fasterxml.jackson.annotation.JsonFormat; import io.swagger.annotations.ApiModel; import io.swagger.annotations.ApiModelProperty; import lombok.Data; import lombok.experimental.Accessors; import org.jeecgframework.poi.excel.annotation.Excel; import org.springframework.format.annotation.DateTimeFormat; import java.util.Date; @Data @Accessors(chain = true) @ApiModel(value = "实践打卡记录vo", description = "实践打卡记录vo") public class RecordImportVo { @ApiModelProperty(value = "姓名/学号") @Excel(name = "姓名/学号", width = 35,orderNum = "1") private String name; @ApiModelProperty(value = "学院") @Excel(name = "学院", width = 35,orderNum = "2") private String college; @ApiModelProperty(value = "位置") @Excel(name = "位置", width = 50,orderNum = "3") private String position; @ApiModelProperty(value = "打卡时间") @JsonFormat(timezone = "GMT+8", pattern = "yyyy-MM-dd HH:mm:ss") @DateTimeFormat(pattern = "yyyy-MM-dd HH:mm:ss") @Excel(name = "打卡时间", width = 35,orderNum = "4") private Date createTime; @ApiModelProperty(value = "备注") @Excel(name = "备注", width = 50,orderNum = "5") private String remark; } 参数是否有误
根据你提供的代码,参数设置看起来是正确的。每个字段都使用了`@Excel`注解指定了导出的列名、宽度和顺序。
但是,要注意确保你的项目中是否有正确引入`org.jeecgframework.poi.excel.annotation.Excel`和相关依赖。如果缺少这些依赖,可能会导致参数错误的异常。
此外,如果你使用的是较旧版本的`org.jeecgframework.poi`库,可能需要检查是否有更新的版本可用。有时候,旧版本的库可能存在一些已知的问题,更新到最新版本可能会解决一些问题。
如果你仍然遇到参数错误的异常,请提供具体的异常信息,以便更进一步地排查问题。
