原因是没有给导出的实体类属性加注解, 形如:

/**

public class CAReconAbnVo {

    @Excel(name="refNo",width=32)
    private java.lang.String refNo;
    @Excel(name="reconTime",width=32)
    private java.util.Date reconTime;
    @Excel(name="batchNo",width=32)
    private java.lang.String batchNo;
    @Excel(name="accNo",width=32)
    private java.lang.String accNo;
    @Excel(name="ppmsTopupAmt",width=32)
    private BigDecimal ppmsTopupAmt;
    @Excel(name="caTopupAmt",width=32)
    private BigDecimal caTopupAmt;
