Create a table using MySQL - Hibernate

To create the table, you need to insert the following lines into application.properties -

spring.jpa.hibernate.ddl-auto=update

Here, Hibernate will automatically create the table demo88. The application.properties code is as follows-

spring.datasource.platform=mysql
spring.jpa.database-platform=org.hibernate.dialect.MySQL5InnoDBDialect
spring.jpa.hibernate.ddl-auto=update
server.port=8191

spring.datasource.driverClassName=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost:3306/sampledatabase
spring.datasource.username=root
spring.datasource.password=123456

demo88 entity class creation table column is as follows-

Example

package com.automaticallytablecreation;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.Id;
import javax.persistence.Table;

@Entity
@Table
public class demo88 {
   @Id
   private int id;
   @Column(name="name")
   private String name;
}

The main class code is as follows-

Example

package com.automaticallytablecreation;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class AutomaticTableApplication {
   public static void main(String[] args) {
      SpringApplication.run(AutomaticTableApplication.class, args);
   }
}

Now right click on the main class and click on the "Run as Java Application" menu. The application will run and create the table.

This will produce the following output-

Output

For verification, let us display the table-

mysql> show create table demo88;

This will produce the following output-

Output
