如何使用Hibernate JPA保存Maven库的对象？

<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-core</artifactId>
    <version>5.4.32.Final</version>
</dependency>

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

    // 其他属性和方法
}

<persistence-unit name="myPersistenceUnit" transaction-type="RESOURCE_LOCAL">
    <provider>org.hibernate.jpa.HibernatePersistenceProvider</provider>
    <class>com.example.MyEntity</class>
    <properties>
        <property name="javax.persistence.jdbc.url" value="jdbc:mysql://localhost:3306/my_database"/>
        <property name="javax.persistence.jdbc.user" value="username"/>
        <property name="javax.persistence.jdbc.password" value="password"/>
        <property name="javax.persistence.jdbc.driver" value="com.mysql.jdbc.Driver"/>
        <property name="hibernate.dialect" value="org.hibernate.dialect.MySQL5Dialect"/>
        <property name="hibernate.hbm2ddl.auto" value="update"/>
    </properties>
</persistence-unit>

EntityManagerFactory emf = Persistence.createEntityManagerFactory("myPersistenceUnit");
EntityManager em = emf.createEntityManager();

MyEntity entity = new MyEntity();
// 设置实体对象的属性

em.getTransaction().begin();
em.persist(entity);
em.getTransaction().commit();

em.close();
emf.close();
