我们的DTO如下:
`@Setter
@Getter
@ToString
public class ModelPriceDTO extends BaseModelDTO implements Serializable {
private static final long serialVersionUID = 3714041108118216990L;
/**
* 官方指导价(元)
*/
private Integer guidePrice;
/**
* 经销商指导价(元)
*/
private Integer dealerPrice;
/**
* 平均价格(元)
*/
private Integer avgPrice;
/**
* 购置税(元)
*/
private Integer purchase;
/**
* 价格别名
*/
private String alias;
public ModelPriceDTO() {
}
public ModelPriceDTO(String modelCode) {
super.setModelCode(modelCode);
}
}`
BaseModelDTO如下:
`
@Setter
@Getter
@ToString
public abstract class BaseModelDTO {
/**
* 车型编码
*/
private String modelCode;
}
