I am new to Springboot and I am trying to create a simple example Account entity class.

Ma20099449BankApplication.java class

@SpringBootApplication
public class Ma20099449BankApplication {

    public static void main(String[] args) {
        // SpringApplication.run(Ma20099449BankApplication.class, args);
        // System.out.println("I am working");
        ApplicationContext context = SpringApplication.run(Ma20099449BankApplication.class, args);

        System.out.println("I have started !!!!");
    }

}

Account.java class

package ma20099449.foundation.bank.ma20099449_bank.Entities;

import javax.persistence.*;

@Entity
@Table(name = "Account")
public class Account {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private int id;

    public int accountNumber;
    public String accountType;
    public int balance;
//I have skipped getters, constructores and to string method.
}

AccountRepository.java class

package ma20099449.foundation.bank.ma20099449_bank.Dao;
import ma20099449.foundation.bank.ma20099449_bank.Entities.Account;

import org.springframework.data.repository.CrudRepository;

public interface AccountRepository extends CrudRepository<Account,Integer> {
    
}

Application.properties file


#configuring application name  
spring.application.name=ma20099449_bank  
#configuring port  
server.port=8081
#configurations of data source
        
spring.datasource.name=bank_project# it is name of datasource property, not name of database, we give it unique name
spring.datasource.url=jdbc:mysql://localhost:3306/bank
# jdbc is protocol
# mysql is subprotocol
# and test is name of database to which we want to connect
spring.datasource.username=root
spring.datasource.password=1234
#If we don't have password then don't write this property
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.MySQL57Dialect
# if table is not created so we will automatically create a table using hibernate in the database using below command
spring.jpa.hibernate.ddl-auto=update #it will automatically create tables for all declared entities

When I am trying to run this application, I am getting below error

It seems that your Application.propertiesfile has a wrong key value, change this line: spring.jpa.hibernate.ddl-auto=update #it will automatically create tables for all declared entities

for it:

spring.jpa.hibernate.ddl-auto=update

#it will automatically create tables for all declared entities

try to not comment in front of the value, I think it can be the problem because your error log: Caused by: java.lang.IllegalArgumentException: Unrecognized legacy hibernate.hbm2ddl.auto value : update #it will automatically create tables for all declared entities
