Spring Boot中Java Model类无法在PostgreSQL自动创建表问题

程序运行无报错，已为Student实体添加所有必要注解，PostgreSQL连接配置也确认正确，但数据库中始终没有生成对应的表。操作步骤完全参照某视频教程的1:11:25-1:16:51时段，使用Eclipse IDE，怀疑问题出在IDE上。

Student实体类代码 #

package ru.kors.springstudents.model;

import jakarta.persistence.*;
import lombok.*;

import java.time.LocalDate;
import java.time.Period;

@Data
@Entity
@Table(name = "students")
public class Student {
    @Id
    @GeneratedValue
    private Long id;
    private String firstName;
    private String lastName;
    private LocalDate dateOfBirth;
    @Column(unique = true)
    private String email;
    @Transient
    private int age;

    public int getAge() {
        return Period.between(dateOfBirth, LocalDate.now()).getYears();
    }
}

更新后的application.yaml配置 #

spring:
  datasource:
    url: jdbc:postgresql://localhost:5432/SpringStudent101
    username: postgres
    password: 4221
    driver-class-name: org.postgresql.Driver

  jpa:
    hibernate:
      ddl-auto: create-drop
    database-platform: org.hibernate.dialect.PostgreSQLDialect
    show-sql: true
    properties:
      hibernate:
        format_sql: true

数据库的Tables目录下本应出现Student对应的表，但目前未生成，可查看截图：
