@excelproperty不显示列名
时间: 2023-09-29 12:02:26 浏览: 46
如果Excel表格中不显示列名,可以按照以下步骤进行操作:
1. 选中表格中的第一行。
2. 点击“查看”选项卡中的“冻结窗格”按钮,选择“冻结首行”。
3. 如果表格中的列名已经存在但是被隐藏了,可以选中整个表格,然后点击“开始”选项卡中的“格式”按钮,选择“隐藏与显示”选项卡,然后取消勾选“列”。
如果以上方法不起作用,可能是因为Excel文件被损坏或者出现了其他异常情况,可以尝试重新打开Excel文件或者使用修复工具进行修复。

把下面代码缺失字段补充完整 并对index进行排序 @ExcelProperty(value = "申告来源", index = 13) @ColumnWidth(20) private String @ExcelProperty(value = "申告时间", index = 14) @ColumnWidth(20) private String @ExcelProperty(value = "编号", index = 15) @ColumnWidth(20) private String @ExcelProperty(value = "新产品名称", index = 16) @ColumnWidth(20) private String @ExcelProperty(value = "故障发生时间", index = 17) @ColumnWidth(20) private String @ExcelProperty(value = "故障修复时间", index = 18) @ColumnWidth(20) private String @ExcelProperty(value = "业务分类", index = 19) @ColumnWidth(20) private String @ExcelProperty(value = "业务小类", index = 20) @ColumnWidth(20) private String @ExcelProperty(value = "派单省", index = 21) @ColumnWidth(20) private String @ExcelProperty(value = "派单人", index = 22) @ColumnWidth(20) private String @ExcelProperty(value = "派单时间", index = 23) @ColumnWidth(20) private String @ExcelProperty(value = "派单用时", index = 24) @ColumnWidth(20) private String @ExcelProperty(value = "确认时间", index = 25) @ColumnWidth(20) private String @ExcelProperty(value = "确认用时", index = 26) @ColumnWidth(20) private String @ExcelProperty(value = "处理省", index = 27) @ColumnWidth(20) private String @ExcelProperty(value = "处理省市", index = 28) @ColumnWidth(20) private String @ExcelProperty(value = "收单用时", index = 29) @ColumnWidth(20) private String @ExcelProperty(value = "故障原因", index = 30) @ColumnWidth(20) private String @ExcelProperty(value = "故障级别", index = 0) @ColumnWidth(20) private String @ExcelProperty(value = "故障类型", index = 0) @ColumnWidth(20) private String @ExcelProperty(value = "故障子类型", index = 0) @ColumnWidth(20) private String @ExcelProperty(value = "业务不可用时长", index = 0) @ColumnWidth(20) private String @ExcelProperty(value = "故障历时", index = 0) @ColumnWidth(20) private String @ExcelProperty(value = "免责时长", index = 0) @ColumnWidth(20) private String @ExcelProperty(value = "客户确认业务恢复时间", index = 0) @ColumnWidth(20) private String @ExcelProperty(value = "FAULT_PROV", index = 0) @ColumnWidth(20) private String @ExcelProperty(value = "项目名称", index = 0) @ColumnWidth(20) priva
由于缺失字段的类型和默认值未知,因此以下代码中只是简单地补充了缺失字段,并对 index 进行了排序:
```
@ExcelProperty(value = "故障级别", index = 0) @ColumnWidth(20) private String faultLevel = "";
@ExcelProperty(value = "故障类型", index = 0) @ColumnWidth(20) private String faultType = "";
@ExcelProperty(value = "故障子类型", index = 0) @ColumnWidth(20) private String faultSubType = "";
@ExcelProperty(value = "业务不可用时长", index = 0) @ColumnWidth(20) private String unavailableDuration = "";
@ExcelProperty(value = "故障历时", index = 0) @ColumnWidth(20) private String faultDuration = "";
@ExcelProperty(value = "免责时长", index = 0) @ColumnWidth(20) private String exemptionDuration = "";
@ExcelProperty(value = "客户确认业务恢复时间", index = 0) @ColumnWidth(20) private String recoverTime = "";
@ExcelProperty(value = "FAULT_PROV", index = 0) @ColumnWidth(20) private String faultProv = "";
@ExcelProperty(value = "项目名称", index = 0) @ColumnWidth(20) private String projectName = "";
@ExcelProperty(value = "申告来源", index = 13) @ColumnWidth(20) private String declareSource = "";
@ExcelProperty(value = "申告时间", index = 14) @ColumnWidth(20) private String declareTime = "";
@ExcelProperty(value = "编号", index = 15) @ColumnWidth(20) private String number = "";
@ExcelProperty(value = "新产品名称", index = 16) @ColumnWidth(20) private String newProductName = "";
@ExcelProperty(value = "故障发生时间", index = 17) @ColumnWidth(20) private String faultStartTime = "";
@ExcelProperty(value = "故障修复时间", index = 18) @ColumnWidth(20) private String faultEndTime = "";
@ExcelProperty(value = "业务分类", index = 19) @ColumnWidth(20) private String businessCategory = "";
@ExcelProperty(value = "业务小类", index = 20) @ColumnWidth(20) private String businessSubCategory = "";
@ExcelProperty(value = "派单省", index = 21) @ColumnWidth(20) private String dispatchProvince = "";
@ExcelProperty(value = "派单人", index = 22) @ColumnWidth(20) private String dispatcher = "";
@ExcelProperty(value = "派单时间", index = 23) @ColumnWidth(20) private String dispatchTime = "";
@ExcelProperty(value = "派单用时", index = 24) @ColumnWidth(20) private String dispatchDuration = "";
@ExcelProperty(value = "确认时间", index = 25) @ColumnWidth(20) private String confirmTime = "";
@ExcelProperty(value = "确认用时", index = 26) @ColumnWidth(20) private String confirmDuration = "";
@ExcelProperty(value = "处理省", index = 27) @ColumnWidth(20) private String processProvince = "";
@ExcelProperty(value = "处理省市", index = 28) @ColumnWidth(20) private String processCity = "";
@ExcelProperty(value = "收单用时", index = 29) @ColumnWidth(20) private String receiptDuration = "";
@ExcelProperty(value = "故障原因", index = 30) @ColumnWidth(20) private String faultReason = "";
// 对 index 进行排序
List<Field> fields = Arrays.asList(this.getClass().getDeclaredFields());
fields.sort(Comparator.comparingInt(f -> f.getAnnotation(ExcelProperty.class).index()));
```
请注意,补充字段的类型和默认值需要根据实际情况进行调整。
@ExcelProperty 注解用法
@ExcelProperty 注解是 EasyExcel 框架提供的注解之一,用于指定 Excel 中的列索引或列名。
@ExcelProperty 注解有两种使用方式:
1. 指定列名:
```java
public class DemoData {
@ExcelProperty("姓名")
private String name;
@ExcelProperty("年龄")
private Integer age;
// Getters and setters
}
```
在上述示例中,@ExcelProperty 注解用于指定 Excel 列的名称。
2. 指定列索引:
```java
public class DemoData {
@ExcelProperty(index = 0)
private String name;
@ExcelProperty(index = 1)
private Integer age;
// Getters and setters
}
```
在上述示例中,@ExcelProperty 注解用于指定 Excel 列的索引,索引从 0 开始。
使用 @ExcelProperty 注解后,请确保正确配置了 EasyExcel 的读写器,以便正确地读取和写入 Excel 文件。
需要注意的是,@ExcelProperty 注解只能用于类的字段上,不能用于方法或其他地方。同时,注解的值必须是字符串类型或整数类型。
这是 @ExcelProperty 注解的基本用法,您可以根据实际需求进行调整和扩展。
