您好，我在 docker 上运行 postgres 映像时尝试使用 kotlin 和 spring boot 构建应用程序，但我不断收到此错误

.....

这是我的实体

@Entity
data class User(
    @Id
    @GeneratedValue
    val id: Long,
    val firstName: String,
    val lastName: String,
    val age:Int,
    val gender:String
    )

这是我的仓库

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

@Repository
interface UserRepository : JpaRepository<User, Long>

这是我的控制器

@RestController
class UserRestController {


    @Autowired
    lateinit var userRepository: UserRepository

    @RequestMapping(value = "/addUser")
    fun save(): User {

        return userRepository.save(User(id=1,firstName = "chaima",lastName = "ennar",age = 20,gender = "female"))

    }


}

我的问题是：这个错误是什么意思？我做错了什么？

【问题讨论】：

标签： postgresql spring-boot kotlin spring-data-jpa

【解决方案1】：

这似乎是这个问题的重复：java.lang.NoSuchMethodError: javax.persistence.spi.PersistenceUnitInfo.getValidationMode()Ljavax/persistence/ValidationMode;

您似乎正在从运行时类路径中获取 JPA v1 库，但您尝试调用的方法仅在 JPA v2 中定义
