在使用休眠模式执行数据库更新时遇到问题。尝试执行repository.add（Object）操作时，它会给出一个验证异常。

我已经在模型类上添加了验证，但是我尝试插入的值似乎可以满足要求，所以我不知道出了什么问题。

如果删除验证批注，repository.add（object）可能会成功完成，即

$tagQuery ="SELECT p.srNumber,h.handoverFrom,h.handoverRemarks FROM plannertags p
                                JOIN handovertable h
                                on p.srNumber = h.plannerTagsId
                               WHERE (p.status = '0' OR p.status = '2') AND p.currentStage = '1' AND p.assignedTo = '0' AND p.handoverStatus = '1' AND p.failedStatus = '1' AND h.latestTag = '1'
                               ORDER BY p.deliveryDate ASC";

请查看是否有任何建议，非常感谢。

MySQL（8.0.17）模式

休眠配置（application-test.yml）

//  @Max(value = 30,message = "Name can only have a maximum length of 30")
//  @Max(value = 30,message = "Color can only have a maximum length of 30")

模型（Car.java）

存储库（CarRepository.java）

package com.example.demo.model;

import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.validation.constraints.Max;
import javax.validation.constraints.NotNull;

import io.swagger.annotations.ApiModel;
import io.swagger.annotations.ApiModelProperty;
import io.swagger.v3.oas.annotations.media.Schema;
import lombok.Data;

@ApiModel(value = "Car",description = "The model for car")
@Schema
@Entity
@Data
public class Car {
    @ApiModelProperty(notes = "Car ID.",example = "12345",required = false,position = 0)
    @Id
    @GeneratedValue
    private Long id;

    @ApiModelProperty(notes = "Car name.",example = "Suzuki Swift 2020",required = true,position = 1)
    @NotNull
    @Max(value = 30,message = "Name can only have a maximum length of 30")
    private String name;

    @ApiModelProperty(notes = "Car color.",example = "blue",position = 2)
    @NotNull
    @Max(value = 30,message = "Color can only have a maximum length of 30")
    private String color;
}

服务（TestService.java）

package com.example.demo.repo;

import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.stereotype.Repository;

import com.example.demo.model.Car;

@Repository
public interface CarRepository extends JpaRepository<Car,Long> {

}

Spring Boot 2.3.1

与Maven（pom.xml）数据相关的依赖项

...
......
public List<Car> getallCars() {
    return carRepository.findAll();
}

public void addNewCar(Car car) {
    carRepository.save(car);
}

public void deleteAllCars() {
    carRepository.deleteAll();
}

JUnit测试（MiscTest.java）（应该满足验证要求）

收到异常
