爆错信息

什么意思呢：找不到“转换器”支持类LocalDateTime，就是导入的数据中有LocalDateTime类型的字段，Excel转换不支持LocalDateTime格式，需要写有一个LocalDateTime的转换类;

写转换类

public class LocalDateTimeConverter implements Converter<LocalDateTime> {private static final String DEFAULT_PATTERN="yyyy-MM-dd HH:mm:ss";@Overridepublic Class<LocalDateTime> supportJavaTypeKey() {return LocalDateTime.class;}@Overridepublic CellDataTypeEnum supportExcelTypeKey() {return CellDataTypeEnum.STRING;}@Overridepublic LocalDateTime convertToJavaData(CellData cellData, ExcelContentProperty contentProperty, GlobalConfiguration globalConfiguration) throws Exception {return LocalDateTime.parse(cellData.getStringValue(), DateTimeFormatter.ofPattern(DEFAULT_PATTERN));}@Overridepublic CellData convertToExcelData(LocalDateTime value, ExcelContentProperty contentProperty, GlobalConfiguration globalConfiguration) throws Exception {return new CellData<>(value.format(DateTimeFormatter.ofPattern(DEFAULT_PATTERN)));}
}
