Hibernate has difficult with create table using MySQL

Question

I'm doing a school project in architecture client-server with JavaFX, Maven, Hibernate etc I have big problem with implementation alone Hibernate (without Spring). Im not sure that is problem with configuration, dependencies or MySQL :\/

<?xml version = "1.0" encoding = "utf-8"?> <!DOCTYPE hibernate-configuration SYSTEM
        "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd"> <hibernate-configuration>
    <session-factory>


        <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
        <property name="hibernate.connection.url">jdbc:mysql://localhost:3306/carrental</property>
        <property name="hibernate.connection.username">root</property>
        <property name="hibernate.connection.password"></property>

        <property name="connection.pool_size">10</property>

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

        <property name="current_session_context_class">thread</property>

        <property name="show_sql">true</property>
        <property name="format_sql">true</property>

        <property name="hbm2ddl.auto">update</property>


        <!-- List of mapping files -->
        <mapping class="model.User" />



    </session-factory> </hibernate-configuration>

Answer 1

Refer to this line in stacktrace:

You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'type=MyISAM' at line

This suggests that you are using an updated version of MySQL but using and old dialect.

Change

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

to

<property name="dialect">org.hibernate.dialect.MySQL5Dialect</property>

Answer 2

Your current dialect generates following

type=MyISAM

where it need to be changed to

ENGINE=MyISAM

in the create table query by Hibernate.

To acheive this you need to use different dialects . Because MySQLDialect is old although you use an updated version of MySQL .

Use either,

<property name="hibernate.dialect">org.hibernate.dialect.MySQL5Dialect</property>

OR

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

in the hibernate.cfg.xml file.

Now you can go ahead with the create query without any dialect errors .

Answer 3

Can you add annotation on Id property and try Of

@GeneratedValue(strategy = GenerationType.IDENTITY)

And let the DateBase manage the incrementation of the primary key:

AUTO_INCREMENT PRIMARY KEY

Hope this helps!

Answer 4

I faced the same problem in Spring Boot Application.

I was using XAMP.

I fixed the issue by changing the Hibernate Dialect in application.properties

From

spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.MySQLDialect

To

spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.MySQL8Dialect

Answer 5

就我而言，我不小心将“desc”放在列名中，并面临同样的问题。

Answer 6

I faced the error "Error executing DDL "create table hibernate_sequence (next_val bigint) type=MyISAM" via JDBC Statement"

I changed org.hibernate.dialect.MySQLDialect to org.hibernate.dialect.MySQL5Dialect and it worked
