属性值为null的时候不调用converter

I'm unable to replicate the problem you've described. Offering a minimal reproducible demo would be an excellent approach.

`public class ExportExcelTest {

public static void main(String[] args) {
    ExcelCell cell = new ExcelCell();
    cell.setName("测试");
    List<ExcelCell> cells = new ArrayList<>();
    cells.add(cell);
    EasyExcel.write(new File("D:\\test11.xlsx"), ExcelCell.class).sheet("模板").doWrite(cells);
}

@Getter
@Setter
@ExcelIgnoreUnannotated
public static class ExcelCell {
    @ExcelProperty(value = "姓名")
    private String name;

    /**
     * 期望null或者false的时候打印出否 true的时候打印出是
     */
    @ExcelProperty(value = "是否通过", converter = BaseConverter.class)
    private Boolean isPass;

}

public static class BaseConverter implements Converter<Boolean> {
    @Override
    public Class<?> supportJavaTypeKey() {
        return Boolean.class;
    }

    @Override
    public CellDataTypeEnum supportExcelTypeKey() {
        return CellDataTypeEnum.STRING;
    }

    @Override
    public Boolean convertToJavaData(ReadCellData<?> cellData, ExcelContentProperty contentProperty,
                                     GlobalConfiguration globalConfiguration) {
        return Boolean.valueOf(cellData.getStringValue());
    }

    @Override
    public WriteCellData<?> convertToExcelData(Boolean value, ExcelContentProperty contentProperty,
                                               GlobalConfiguration globalConfiguration) {

        String str = "否";
        if (Boolean.TRUE.equals(value)){
            str = "是";
        }
        if (Boolean.FALSE.equals(value)){
            str = "否";
        }

        if (Objects.isNull(value)) {
            str = "否";
        }
        return new WriteCellData<>(str);
    }
}

}
