如何读取表头，只读取第一行就让它中断，如何中断解析

[xianJieHao]

有个10万数据的excel，想要读取第一行（表头）然后中断解析，只为了校验表头正不正确，怎么处理。

@Getter
public class EasyExcelHeaderListener extends AnalysisEventListener<Map<String, String>> {

    private List<String> excelHeaderNameList = new ArrayList<>();

    @Override
    public void invoke(Map<String, String> data, AnalysisContext context) {
    }

    @Override
    public void invokeHeadMap(Map<Integer, String> headMap, AnalysisContext context) {
        excelHeaderNameList = new ArrayList<>(headMap.values());
    }

    @Override
    public void doAfterAllAnalysed(AnalysisContext analysisContext) {
    }

    @Override
    public boolean hasNext(AnalysisContext context) {
        return false;
    }

}

EasyExcelHeaderListener easyExcelHeaderListener = new EasyExcelHeaderListener();
        try {
            // 异常捕获，因为hasNext会抛出异常
            EasyExcel.read(inputStream, easyExcelHeaderListener).sheet(0).doRead();
        } catch (Exception e) {
            log.info("获取头部列名成功，正常退出");
        }
        List<String> headerNameList = easyExcelHeaderListener.getExcelHeaderNameList();
