Кажется, JPA Spring.jpa.hibernate.ddl-auto=update не работает ⇐ JAVA

[Anonymous]

Я создаю простое приложение SpringBoot (версия: 2.4.3). У меня есть следующая сущность:

Код: Выделить всё

package com.ksteindl.logolo.domain;

import javax.persistence.Entity;
import javax.persistence.Id;

@Entity
public class Foo {

@Id
private String id;
private String foo;

public String getFoo() {
return foo;
}

public void setFoo(String foo) {
this.foo = foo;
}

public void setId(String id) {
this.id = id;
}

public String getId() {
return id;
}
}

и application.properties

Код: Выделить всё

spring.jpa.show-sql=true

spring.datasource.url = jdbc:mysql://localhost:3306/mysql
spring.datasource.username=admin
spring.datasource.password=admin

spring.jpa.database-platform=org.hibernate.dialect.MySQL5Dialect

spring.jpa.hibernate.ddl-auto=update

spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL57Dialect

При первом запуске все кажется хорошо. Таблицы создаются в соответствии с Entites.
Однако, когда я перезапускаю свое приложение, я получаю исключения для каждой имеющейся у меня сущности/таблицы. Более того, если я изменю свою сущность (например, введу атрибут bar в Foo Entity), соответствующая таблица не изменится в БД.
Мне кажется, что она пытается воссоздать таблицы, но Я не знаю почему.
Я получил следующие исключения для каждой имеющейся у меня таблицы/сущности:
