The project uses a database MySql, Open Server. Here is my application.properties file:

Here is my entity:

@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private Long ID;
private String ru, by, ua, en;
public Long GetID() { return ID; }
public void SetID(Long ID) { this.ID = ID; }
public String GetBy() { return by; }
public void SetBy(String by) { this.by = by; }
public String GetRu() { return ru; }
public void SetRu(String ru) { this.ru = ru; }
public String GetUa() { return ua; }
public void SetUa(String ua) { this.ua = ua; }
public String GetEn() { return en; }
public void SetEn(String en) { this.by = en; }

By the way, everything is fine in the pom.xml file, all the necessary dependencies are registered:

Here is logging out from Spring application:

I checked the port, database name, username and password - everything is correct. However, when I run the application and go to phpMyAdmin, I see a message that no tables were found in the database. What could be the issue here?

**得分**: 1
你正在使用spring-boot 3.1.2，这意味着你应该将你的
import javax.persistence.*;
替换为
import jakarta.persistence.*;
关于你的Maven依赖，你应该移除这个
<dependency>
<groupId>javax.persistence</groupId>
<artifactId>javax.persistence-api</artifactId>
<version>2.2</version>
</dependency>
因为你使用了
spring-boot-starter-data-jpa
它依赖于Hibernate。Hibernate然后依赖于jakarta.persistence API，使其类可用于你的应用程序代码。
关于你的问题，应用程序启动后你看不到表格。
只需尝试替换应用程序属性参数
spring.jpa.hibernate.ddl-auto=create
在首次运行应用程序后，将其替换为 `update`

Your are using spring-boot 3.1.2, it mean you should replace your 
import javax.persistence.*;
with
import jakarta.persistence.*;
About your maven dependency you should to remove this one
&lt;dependency&gt;
&lt;groupId&gt;javax.persistence&lt;/groupId&gt;
&lt;artifactId&gt;javax.persistence-api&lt;/artifactId&gt;
&lt;version&gt;2.2&lt;/version&gt;
&lt;/dependency&gt;
because you use 
spring-boot-starter-data-jpa
it has dependencies on Hibernate. Hibernate then has a dependency on the jakarta.persistence API which makes its classes available to your application&#39;s code.
About your problem, you don&#39;t see the tables after application start. 
Just try to replace an application properties param 
spring.jpa.hibernate.ddl-auto=create
And after first run of application 
replace with `update`
