## 一、异常 ##

程序编译通过，执行报错：

{
        
        "code": 500,
        "message": "HV000030: No validator could be found for constraint 'javax.validation.constraints.NotEmpty' validating type 'java.lang.Long'. Check configuration for 'vehicleTypeId'",
        "data": null
    }

## 二、报错分析 ##

创建的类对象如下：

@Getter
    @Setter
    @TableName(value = "app_vehicle", autoResultMap = true)
    public class Vehicle extends Model<Vehicle> {
        
        private static final long serialVersionUID = 1L;
        //车辆编号
        @TableId(type = IdType.AUTO)
        private Long id;
        //VIN码
        @NotEmpty(message = "VIN码不能为空")
        private String deviceId;
        //车型编号
        @NotEmpty(message = "车型编号不能为空")
        private Long vehicleTypeId;
        //车机版本
        private String vehicleVersion;
        //车辆类型
        private String type;
        //车辆激活状态
        private String status;
    }

这里的vehicleTypeId字段数据类型为Long，校验注解使用`@NotEmpty`报错了，是因为`@NotEmpty`一般作用在集合类或者数组类上，而针对数值类型校验一般使用`@NotNull`

## 三、报错解决 ##

更换为@NotNull判非空之后就不报错了

//车型编号
    @NotNull(message = "车型编号不能为空")
    private Long vehicleTypeId;
