1.所有的操作都在监听器里面进行

public Map<String, String> map = new HashMap<>();
List<DictEeVo> list = new ArrayList<>();


@Override
public void invokeHeadMap(Map<Integer, String> headMap, AnalysisContext context) {

    String s = headMap.get(0);
    String s1 = headMap.get(1);
    if (!s.equals("id") || !s1.equals("名称")){
        map.put("msg","模板无法撇皮");
    }

    System.out.println(headMap.toString());


}

DictListener listener = new DictListener(baseMapper);
EasyExcel.read(file.getInputStream(),DictEeVo.class,listener).sheet().doRead();
List<Dict> dicts = baseMapper.selectList(null);
Map<String, String> map = listener.map;
if (!map.isEmpty()){
    System.out.println("不搬丢很大");
    return  Result.fail(201);
}

类中设置成public可以直接获取
