使用Easypoi 4.0

1、 使用Map方式

String[] titles = {"学校名称","班级","学生姓名","身份证号"};
ImportParams params = new ImportParams();
String [] t = titleList.toArray(new String[titleList.size()]);
params.setImportFields(t);
List<Map<String, Object>> list = 
    ExcelImportUtil.importExcel(file.getInputStream(), Map.class, params);

2、 使用实体类方式

实体类
public class ExamineeImportBO {
//
    @Excel(name = "学校",type=1)
    private String school;
    @Excel(name = "姓名",type=1)
    private String name;
//... 

List<ExamineeImportBO> dataList =
     ExcelImportUtil.importExcel(file.getInputStream(), 
            ExamineeImportBO.class, new ImportParams());

for (ExamineeImportBO examineeBO : examineeImportBOList) {
         List<String> errMessageList = new ArrayList<>();
         Map<String, Object> dbObj = new HashMap<>();
         Map<String, Object> rowObj = BeanUtils.toMap(examineeBO);
