1、導包

2、數據庫建模

3、創建持久化類（POJO）
注意：
①、需提供一個無參的構造器，因為hibernate使用反射來實例化持久化類（Constructor.newInstance()）
否則報錯：
INFO: HHH000327: Error performing load command : org.hibernate.InstantiationException: No default constructor for entity: com.hibernate.domain.Customer

package com.hibernate.domain;
public class Customer {
    private int custID;
    private String custName;
    private String phone;
    private String address;
    public int getCustID() {
        return custID;
    }
    public void setCustID(int custID) {
        this.custID = custID;
    }
    public String getCustName() {
        return custName;
    }
    public void setCustName(String custName) {
        this.custName = custName;
    }
    public String getPhone() {
        return phone;
    }
    public void setPhone(String phone) {
        this.phone = phone;
    }
    public String getAddress() {
        return address;
    }
    public void setAddress(String address) {
        this.address = address;
    }
    public Customer(int custID, String custName, String phone, String address) {
        super();
        this.custID = custID;
        this.custName = custName;
        this.phone = phone;
        this.address = address;
    }
    public Customer() {

    }
}

4、創建映射文件（xxx.hbm.xml）

Customer.hbm.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd" >
<hibernate-mapping>
    <class name="com.hibernate.domain.Customer" table="customer">
    <!-- name：對應的持久化類的全類名    table：對應的表名 -->

        <!-- 下面建立類中的字段 和 表中列的對應關系
        id：建立類中字段與表的主鍵之間的對應關系
            name：類中的字段名
            column：數據庫中的列名

            generator：主鍵生成策略
        -->
        <id name="custID" column="cust_id">
            <generator class="native"></generator>
        </id>

        <!-- 
        property：建立類中字段與表中普通列之間的對應關系
            name：類中的字段名
            column：數據庫中的列名
         -->
        <property name="custName" column="cust_name"></property>
        <property name="phone" column="cust_phone"></property>
        <property name="address" column="cust_addr"></property>
    </class>
</hibernate-mapping>

5、創建Hibernate核心配置文件（hibernate.cfg.xml）

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC
        "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
        "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
    <session-factory>
        <!-- 數據庫連接的基礎配置，必須項 -->
        <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
        <property name="hibernate.connection.password">password</property>
        <property name="hibernate.connection.url">jdbc:mysql:///hibernate1</property>
        <property name="hibernate.connection.username">root</property>

        <!-- 數據庫方言(此處選為mysql) -->
        <property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>

        <!-- 控制臺是否打出sql -->
        <property name="hibernate.show_sql">true</property>
        <!-- sql語句是否格式化 -->
        <property name="hibernate.format_sql">true</property>

        <!-- 映射文件加載 -->
        <mapping resource="com/hibernate/domain/Customer.hbm.xml"/>
    </session-factory>
</hibernate-configuration>

6、測試類

package com.hibernate.test;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.hibernate.cfg.Configuration;
import org.hibernate.service.ServiceRegistry;
import org.hibernate.service.ServiceRegistryBuilder;
import com.hibernate.domain.Customer;
public class Test {
    @org.junit.Test
    public void test() {
        //1、創建Configuration對象，對應hibernate的基本配置信息和對象關系映射信息（即hibernate.cfg.xml 及 XXX.hbm.xml信息）
        Configuration configuration = new Configuration().configure();

        //2、 創建一個 ServiceRegistry 對象
        //hibernate 的任何配置和服務都需要在該對象中注冊后才能有效.
        ServiceRegistry serviceRegistry = 
                new ServiceRegistryBuilder().applySettings(configuration.getProperties())
                                                    .buildServiceRegistry();

        //3、創建sessionFactory
        SessionFactory sessionFactory = configuration.buildSessionFactory(serviceRegistry);

        //4. 創建一個 Session 對象
        Session session = sessionFactory.openSession();

        //5、 開啟事務
        Transaction transaction = session.beginTransaction();

        //6、查詢編碼（主鍵）為1 的用戶
        Customer customer = (Customer)session.get(Customer.class,1);
        System.out.println(customer);
        //7、提交事務
        transaction.commit();

        //8、關閉資源
        session.close();
        sessionFactory.close();

    }
}
