Spring boot does not automatically create database tables on Mysql - spring

Question

First I already went over some solution on stacks but they did not work. I make a very basic/learning app on spring / mysql, no tables joining for the moment. The problem is tables are not creating on mysql, while everything is working. I copy my code hereunder.
Thanks in advance for the help

Answer 1

The main entry point of your application is in the com.javaenterprise.votingsystem package. This means that component and entity scanning will find classes in com.javaenterprise.votingsystem and any of its sub-packages. Your entities are in the com.javaenterprise.entity which isn't covered by this scanning.
You could solve the problem by renaming your com.javaenterprise.entity package to com.javaenterprise.votingsystem.entity. Alternatively, you can use #EntityScan to specify the packages that you want to be scanned for entities.

Answer 2

Use the following property:
spring.datasource.url=jdbc:mysql://localhost:3306/dbname?useSSL=false
spring.datasource.username=root
spring.datasource.password=root
spring.jpa.properties.hibernate.show_sql=true
spring.jpa.properties.hibernate.use_sql_comments=true
spring.jpa.properties.hibernate.format_sql=true
spring.jpa.hibernate.ddl-auto=update
And Second, Please add a default constructor as well.
So ur entity class will become:
package com.javaenterprise.entity;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.Id;
import javax.persistence.Table;
#Entity
#Table(name = "citizens")
#Data
#AllArgsConstructor
#NoArgsConstructor
public class Citizen {
#Id
#Column(name="id")
private Long id;
#Column(name = "citizen_name")
private String name;
}

Answer 3

Can you try implementing Serializable and add DEFAULT Constructor ?

Answer 4

You can use this in your application.properties file
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
spring.datasource.username=root/your username
spring.datasource.password= yourpassword
spring.datasource.url=jdbc:mysql://localhost:3306/kibria
#for mysql dialect
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5Dialect
spring.jpa.hibernate.ddl-auto = update
spring.jpa.show-sql = true
