mysql spring-boot hibernate

Mysql <；Spring Boot/Hibernate>；由于javax.validation.ConstraintViolationException，无法提交JPA事务,mysql,spring-boot,hibernate,spring-data-jpa,javax.validation,Mysql,Spring Boot,Hibernate,Spring Data Jpa,Javax.validation,我在使用hibernate执行数据库更新时遇到了一个问题。尝试repository.add（Object）操作时，会出现验证异常 我已经在模型类上添加了验证，但是我尝试插入的值似乎满足了要求，所以我不知道问题出在哪里 如果删除验证注释，repository.add（object）可以成功完成，即 // @Max(value = 30, message = "Name can only have a maximum length of 30") // @Max(value

我在使用hibernate执行数据库更新时遇到了一个问题。尝试repository.add（Object）操作时，会出现验证异常

我已经在模型类上添加了验证，但是我尝试插入的值似乎满足了要求，所以我不知道问题出在哪里

如果删除验证注释，repository.add（object）可以成功完成，即

//  @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")
请看是否有任何建议，提前非常感谢。

MySQL（8.0.17）模式

Hibernate配置（application test.yml）

模型（Car.java）

存储库（CarRepository.java）

@Max注释似乎不适用于spring boot hibernate。 将其更改为@Size注释时，可以成功完成添加（对象）（即DB插入）

谢谢你的建议。

该@Max注释似乎不适用于spring boot hibernate。 将其更改为@Size注释时，可以成功完成添加（对象）（即DB插入）

谢谢您的建议。

@Size
将取代
@Max
或
@Min

你应该参考以获得更好的理解

主要区别在于：

@Size
用于检查字段的长度约束，它支持
字符串
、
集合
、
映射
和
数组

另一方面，
@Min
和
@Max
用于验证数值字段的值，这些数值字段可以是
字符串（表示数字）
、
int
、
short
、
字节
等。。
或者，它们各自的原始包装将取代
@Max
或
@Min

您是否尝试过使用此注释@尺寸（最大值=30）谢谢，解决了这个问题。因此，似乎并非所有javax.validation containt注释都适用于spring boot hibernate@尺寸（最大值=30）谢谢，解决了这个问题。因此，似乎并非所有javax.validation containt注释都适用于spring boot hibernate。
