Spring java.sql.SQLException：字段'；用户ID'；不'；你没有默认值吗？

当我尝试在postman上测试post方法时，我得到了以下错误。请帮帮我

用户控制器

UserDetailsRequestModel

用户休息

用户数据

UserServiceImpl

用户实体

错误

调试

我试着调试它。似乎我成功地设置了userId。 我知道图片很烦人，但我不知道如何以其他方式显示调试过程

调试过程：

---

除非您使用的是自定义的

物理命名策略

，否则您的属性

用户ID

名称与您的列

用户ID

不匹配。在基于Linux的环境中，MySQL中的列和表名区分大小写

---

您可以使用

@column（name=“userid”）

将属性映射到其他列名。如果您遵循在db列中使用下划线分隔的名称，在Java实体属性中使用驼峰大小写名称的惯例，则更好。

Hibernate命名策略背后的思想是尽量减少开发人员（我们）必须向域模型提供的重复信息。因此，如果您将字段命名为userId，Hibernate需要能够将其映射到相应的表列名，而无需向其提供进一步的信息或元数据。

那么，Hibernate是如何做到的呢？

首先，如果您没有明确指定列名（使用@column（name=“userid”），Hibernate将确定由定义的正确逻辑名。如果您选择

默认/jpa

策略，对于基本属性，它将使用属性的名称作为逻辑名。

第二个，它将此正确的逻辑名称解析为由定义的物理名称。默认情况下，Hibernate使用该逻辑名称作为物理名称。

好消息是

Spring Boot

为这两种策略提供了默认值：

spring.jpa.hibernate.naming.physical-strategy默认为 org.springframework.boot.orm.jpa.hibernate.SpringPhysicalNamingStrategy

spring.jpa.hibernate.naming.implicit-strategy默认为 org.springframework.boot.orm.jpa.hibernate.SpringImplicitNamingStrategy

默认情况下，这些将：
-将camel case更改为snake case（如果您的DBusers表列名为user\u id，则此选项很好
-用下划线替换点。
-小写的表名，但如果您的模式需要，可以覆盖该标志。

您可以显式（这是Spring Boot的默认设置）将其添加为Hibernate属性：

properties.put("hibernate.physical_naming_strategy", "org.springframework.boot.orm.jpa.hibernate.SpringPhysicalNamingStrategy");

或者选择与您的用例相匹配的策略。更多信息。

尽管不推荐，但最简单的方法（对所有@Entity类的所有属性都这样做吗？）是根据Fabricio的答案在UserEntity类中显式定义实际表的列名：

@Column(name = "userid", nullable = false)
private String userId;

并且非常适合了解更多有关命名策略的信息。

最后，您可以打开调试，通过在应用程序中添加此项来查看实际情况。属性：

logging.level.org.hibernate.SQL=DEBUG
logging.level.org.hibernate.type=TRACE
spring.jpa.properties.hibernate.format_sql=true

奖金：
Fabricio提到了这一点：

如果您遵循在db列中使用下划线分隔的名称（即snake-case）和在Java实体属性中使用camel-case名称的惯例，那就更好了。

这也是Spring的惯例。

编辑：

---

主要问题是该列被设置为

@column（nullable=false）

，但我将保留以上所有内容，因为它们都是信息性的。

任何帮助都将不胜感激。您好，@Fabrico，学到了很多关于如何命名专栏的知识。谢谢，但仍然是相同的错误。评论不用于扩展讨论；此对话已经结束。您好@WooLee，我编辑了我的答案。如果它对您有所帮助，您可能会接受它。谢谢。嗨@jumping_monkey，我有一个好消息。它成功了。使用这种方式：@Column（name=“userId”，nullable=false）。非常感谢。你让我开心。是的，当然，我一定会接受你的回答。这是我第二次就StackOverflow提问。你无法想象我刚才遇到了一个多么棒的人。@jumping_monkey今天下午和晚上帮我解决了4个小时的问题，完成了每一个细节，每一步。我学到了很多。谢谢上帝保佑你。
