I have a SpringBoot 2.0.1.RELEASE application using spring data / jpa

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>

But when I do an update in the Amazon Aurora DB, I got this error:

2018-04-13 09:20 [pool-1-thread-1] ERROR o.h.id.enhanced.TableStructure.execute(148) - could not read a hi value com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Table 'elbar.hibernate_sequence' doesn't exist at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method)

I have this in the entity I want to save

@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private Long id;

I would like to avoid also any drawback in the DB to fetch the ID .

With the generation GenerationType.AUTO hibernate will look for the default hibernate_sequence table , so change generation to IDENTITY as below :

 @Id
 @GeneratedValue(strategy = GenerationType.IDENTITY)
 private Long id;

    https://vladmihalcea.com/why-should-not-use-the-auto-jpa-generationtype-with-mysql-and-hibernate/ clearly explains what changed between Hibernate 3 and 5 major versions on handling on GenerationType.AUTO – SudhirR Aug 26 '19 at 07:05

Add the following config in your application.yml:

spring: jpa: hibernate: use-new-id-generator-mappings: false

Or this if you use application.properties

spring.jpa.hibernate.use-new-id-generator-mappings= false

If you are using Hibernate version prior to Hibernate5 @GeneratedValue(strategy = GenerationType.IDENTITY) works like a charm. But post Hibernate5 the following fix is necessary.

@Id
@GeneratedValue(strategy= GenerationType.AUTO,generator="native")
@GenericGenerator(name = "native",strategy = "native")
private Long id;

DDL

`id` BIGINT(20) NOT NULL AUTO_INCREMENT PRIMARY KEY

REASON

Excerpt from hibernate-issue

Currently, if the hibernate.id.new_generator_mappings is set to false, @GeneratedValue(strategy = GenerationType.AUTO) is mapped to native. If this property is true (which is the defult value in 5.x), the @GeneratedValue(strategy = GenerationType.AUTO) is always mapped to SequenceStyleGenerator.

For this reason, on any database that does not support sequences natively (e.g. MySQL) we are going to use the TABLE generator instead of IDENTITY.

However, TABLE generator, although more portable, uses a separate transaction every time a value is being fetched from the database. In fact, even if the IDENTITY disables JDBC batch updates and the TABLE generator uses the pooled optimizer, the IDENTITY still scales better.

Just in case you migrate from a previous boot version:

setting the following in your application.yml will prevent hibernate from looking for hibernate_sequence entries.

spring.jpa.hibernate.use-new-id-generator-mappings

That was the default in Boot 1.x

Warning : This will truncate the data in all tables specified as entities in your application

JPA and Auto-DDL

When I run into mapping mismatches between a table schema and a java entity I like to do the following.

  1. Drop the schema
  2. Add the spring.jpa.hibernate.ddl-auto=create property to application.properties
  3. Restart your application

This will now recreate the schema based on your entity. You can then compare the created table against your old schema to see the difference, if necessary.

You can just create the table:

create table hibernate_sequence(
    next_val INTEGER NOT null
);

just add this code to your application.properties file

spring.jpa.hibernate.ddl-auto=update

I got the same error when I used the following dialect setting:

# Hibernate SQL dialect
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.MySQLDialect

I am using MySQL version 8.0.27, aftter I updated the above setting to:

# Hibernate SQL dialect
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.MySQL8Dialect

Then it worked as expected.

Adding spring.jpa.hibernate.ddl-auto=create in the propoerties file solved the issue

Since I had Server version: 8.0.29 MySQL Community Server - GPL (which you can check from many places, I found from MySQL Command Line client)

In hibernate configuration file earlier I was trying with:

<property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>

Replacing it with following:

<property name="spring.jpa.properties.hibernate.dialect">org.hibernate.dialect.MySQL8Dialect</property>

It worked absolutely fine for me.

 @Id
 @GeneratedValue(strategy = GenerationType.Auto) 
 private Long id;

change GenerationType.Auto to GenerationType.IDENTITY

<property name="hibernate.id.new_generator_mappings" value="false" />
