List类型参数拦截 spring-boot-starter-v

@Data
public class OrderSpecificationParam {

    @Min(value = 1,message = "长度不能为0")
    @NotNull(message = "长")
    @ApiModelProperty(value = "长", required = true)
    private Integer length;

    @Min(value = 1,message = "宽度不能为0")
    @NotNull(message = "宽")
    @ApiModelProperty(value = "宽", required = true)
    private Integer width;

    @Min(value = 1,message = "所需数量不能为0")
    @NotNull(message = "所需数量")
    @ApiModelProperty(value = "所需数量", required = true)
    private Integer quantity;

}

@Data
public class CreateOrderParam {

    @NotNull(message = "间隔条类型")
    @ApiModelProperty(value = "间隔条类型", required = true)
    private Integer firstStepRadioActive;

    @NotNull(message = "玻璃类型")
    @ApiModelProperty(value = "玻璃类型", required = true)
    private Integer secondStepRadioActive;

    @NotNull(message = "二道胶厚度")
    @ApiModelProperty(value = "二道胶厚度", required = true)
    private Integer thirdStepRadioActive;

    @NotNull(message = "上传数据方式")
    @ApiModelProperty(value = "上传数据方式", required = true)
    private Integer fourthStepRadioActive;

    @NotNull(message = "规格数据不能为空")
    @Size(min = 1,message = "规格至数据少有一条")
    private List<@Valid OrderSpecificationParam> specification;

}

List参数要对泛型加上@Valid注解，才能让OrderSpecificationParam进行验证

如果List的泛型不是自定义对象。可以直接在泛型上加对应的注解：

List<@NotNull String> list;
