Debug
I tried to debug it. It seemed I set userId successfully.
I know pics are annoying, but I don't know how to show my debug process in other way.
Debug process:

Answer 1

Hibernate
Hibernate is the interface/link/glue/middleware between your application and the database. It's one of the many framework/libraries, out there, that is making ORM possible and easy. Keyword here is easy, as it makes our lives really simple!
The idea behind Hibernate's naming strategies is to map your POJO(class/model), in your case UserEntity to its respective physical(actual) DB table as seamless as possible(magical, if you will). So, if you name your logical field userId in your POJO, Hibernate needs to be able to map it to the respective physical table column name, example user_id.
Hibernate naming strategies
If you do not explicitly specify the column name(i.e #Column(name = "userid"), Hibernate determines a proper logical name defined by the ImplicitNamingStrategy. If you choose the default/jpa strategy, for basic attributes, it uses the name of the attributes as the logical name. Ideally, all you have to do is:
#Column
private String userId;
So userId is mapped logically to userId implicitly. It further resolves this proper logical name to a physical name, defined by the PhysicalNamingStrategy. By default, Hibernate uses the logical name as the physical name, but the real purpose of the PhysicalNamingStrategy is to say that physical column userId is actually abbreviated to user_id.
Spring Boot
The good news is that Spring Boot provides defaults for both strategies:
spring.jpa.hibernate.naming.physical-strategy defaults to
org.springframework.boot.orm.jpa.hibernate.SpringPhysicalNamingStrategy
spring.jpa.hibernate.naming.implicit-strategy defaults to
org.springframework.boot.orm.jpa.hibernate.SpringImplicitNamingStrategy
By default, Spring Boot configures the physical naming strategy with CamelCaseToUnderscoresNamingStrategy, this strategy will:
-Change camel-case to snake case(Good if your DB users table column name is user_id.
-Replace dots with underscores.
-Lower-case table names, but it is possible to override that flag if your schema requires it.
You could explicitly(it's Spring Boot's default) add it as a Hibernate property:
#Configuration
public class HibernateConfiguration {
Properties hibernateProperties() {
Properties properties = new Properties();
properties.put("hibernate.physical_naming_strategy", "org.springframework.boot.orm.jpa.hibernate.SpringPhysicalNamingStrategy");
#Bean
public LocalContainerEntityManagerFactoryBean entityManagerFactory() {
LocalContainerEntityManagerFactoryBean emf = new LocalContainerEntityManagerFactoryBean();
emf.setDataSource(dataSource);
emf.setJpaProperties(hibernateProperties());
Or choose the strategy that best match your use-case. This and this are excellent to learn more about naming strategies.
Easy, long-winded, but clear
The easiest, although not recommended, unless you have no choice(Will you be doing this for all the attributes of all your #Entity classes?), would be to explicitly defined the actual table's column name, in your UserEntity class:
#Column(name = "userid")
private String userId;
How should you name your columns?
Fabricio mentions this: Better yet if you follow the convention of using underscore separated names for your db columns(i.e snake-case) and camel case names for your Java entity properties. This is also Spring conventions:
#Column
private String userId;
DEBUG
During development, you can turn on debugging to see what's really going on by adding this in your application.properties:
logging.level.org.hibernate.SQL=DEBUG
logging.level.org.hibernate.type=TRACE
spring.jpa.properties.hibernate.format_sql=true
EDIT:
The main issue was that the column was set to #Column(nullable = false), but i will leave all the notes above as it's informative.

Answer 2

Unless you are using a custom PhysicalNamingStrategy, your property userId name does not match your column userid. Column and table name are case sensitive in MySQL on Linux-based environments.
You can map your property to a different column name using #Column(name = "userid"). Better yet if you follow the convention of using underscore separated names for your db columns and camel case names for your Java entity properties.
