读多个sheet 方式二 我理解的是有多个sheet时，可指定sheet读取，但是读取的时候可能会报错

建议先去看文档 快速开始 、常见问题 触发场景描述 读多个sheet，采用方式二，理解可指定sheet读取，在使用时发现，如果第一个sheet没有读取的话，直接读取后面的sheet，会报错，报的是空指针 触发Bug的代码

#BofRecordHandler中  xlsReadContext.xlsReadSheetHolder().setIgnoreRecord(Boolean.TRUE); 报空指针，xlsReadSheetHolder为null
       @Override
    public void processRecord(XlsReadContext xlsReadContext, Record record) {
        BOFRecord br = (BOFRecord)record;
        XlsReadWorkbookHolder xlsReadWorkbookHolder = xlsReadContext.xlsReadWorkbookHolder();
        if (br.getType() == BOFRecord.TYPE_WORKBOOK) {
            xlsReadWorkbookHolder.setReadSheetIndex(null);
            return;
        }
        if (br.getType() != BOFRecord.TYPE_WORKSHEET) {
            return;
        }
        // Init read sheet Data
        initReadSheetDataList(xlsReadWorkbookHolder);
        Integer readSheetIndex = xlsReadWorkbookHolder.getReadSheetIndex();
        if (readSheetIndex == null) {
            readSheetIndex = 0;
            xlsReadWorkbookHolder.setReadSheetIndex(readSheetIndex);
        }
        ReadSheet readSheet = xlsReadWorkbookHolder.getActualSheetDataList().get(readSheetIndex);
        assert readSheet != null : "Can't find the sheet.";
        // Copy the parameter to the current sheet
        readSheet = SheetUtils.match(readSheet, xlsReadContext);
        if (readSheet != null) {
            xlsReadContext.currentSheet(readSheet);
            xlsReadContext.xlsReadSheetHolder().setIgnoreRecord(Boolean.FALSE);
        } else {
            xlsReadContext.xlsReadSheetHolder().setIgnoreRecord(Boolean.TRUE);
        }
        // Go read the next one
        xlsReadWorkbookHolder.setReadSheetIndex(xlsReadWorkbookHolder.getReadSheetIndex() + 1);
    }
