如何使用hibernate连接外部mySQL数据库

<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-core</artifactId>
    <version>5.4.x</version>

<hibernate-configuration>
    <session-factory>
        <!-- 数据库连接相关配置 -->
        <property name="hibernate.connection.url">jdbc:mysql://localhost:3306/your_database</property>
        <property name="hibernate.connection.username">your_username</property>
        <property name="hibernate.connection.password">your_password</property>
        
        <!-- 配置MySQL驱动 -->
        <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
        
        <!-- 配置Hibernate方言 -->
        <property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>
        
        <!-- 配置实体类所在的包路径 -->
        <mapping class="com.example.YourEntityClass"/>
    </session-factory>
</hibernate-configuration>

@Entity
@Table(name = "your_table")
public class YourEntityClass {
    @Id
    private Long id;
    
    // 其他属性和方法
}

// 初始化Hibernate配置
Configuration configuration = new Configuration().configure();
SessionFactory sessionFactory = configuration.buildSessionFactory();

// 创建会话
Session session = sessionFactory.openSession();

// 开启事务
Transaction transaction = session.beginTransaction();

// 进行数据库操作
YourEntityClass entity = new YourEntityClass();
// 设置实体对象的属性

// 保存实体对象到数据库
session.save(entity);

// 提交事务
transaction.commit();

// 关闭会话和SessionFactory
session.close();
sessionFactory.close();
