Hibernate基本配置

---

1.引入jar

2.建立项目

3.创建实体类

package com.sqlserver.domain;
public class Customer {
    long cust_id;
    String cust_name;
    String cust_source;
    String cust_industry;
    String cust_level;
    String cust_phone;
    public Customer() {
    }
    public Customer(long cust_id, String cust_name, String cust_source, String cust_industry, String cust_level,
            String cust_phone) {
        super();
        this.cust_id = cust_id;
        this.cust_name = cust_name;
        this.cust_source = cust_source;
        this.cust_industry = cust_industry;
        this.cust_level = cust_level;
        this.cust_phone = cust_phone;
    }
    public long getCust_id() {
        return cust_id;
    }
    public void setCust_id(long cust_id) {
        this.cust_id = cust_id;
    }
    public String getCust_name() {
        return cust_name;
    }
    public void setCust_name(String cust_name) {
        this.cust_name = cust_name;
    }
    public String getCust_source() {
        return cust_source;
    }
    public void setCust_source(String cust_source) {
        this.cust_source = cust_source;
    }
    public String getCust_industry() {
        return cust_industry;
    }
    public void setCust_industry(String cust_industry) {
        this.cust_industry = cust_industry;
    }
    public String getCust_level() {
        return cust_level;
    }
    public void setCust_level(String cust_level) {
        this.cust_level = cust_level;
    }
    public String getCust_phone() {
        return cust_phone;
    }
    public void setCust_phone(String cust_phone) {
        this.cust_phone = cust_phone;
    }
}

4.创建数据库表

USE [hibernate]
GO

/****** Object:  Table [dbo].[customer]    Script Date: 2019/5/28 20:30:22 ******/
SET ANSI_NULLS ON
GO

SET QUOTED_IDENTIFIER ON
GO

CREATE TABLE [dbo].[customer](
    ,) NOT NULL,
    ) NULL,
    ) NULL,
    ) NULL,
    ) NULL,
    ) NULL,
 CONSTRAINT [pk_001] PRIMARY KEY CLUSTERED
(
    [cust_id] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]

GO

5.JAVA类与数据库表映射classname.hbm.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-mapping PUBLIC
    "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
    "http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">
<hibernate-mapping>
    <class name="com.sqlserver.domain.Customer" table="customer">
        <!-- 主键 -->
        <id name="cust_id" column="cust_id">
        <generator class="native"></generator>
        </id>
        <!-- 普通列关联,name和column一样可以省略column -->
        <property name="cust_name" column="cust_name" />
        <property name="cust_source" column="cust_source"/>
        <property name="cust_industry" column="cust_industry"/>
        <property name="cust_level" column="cust_level"/>
        <property name="cust_phone" column="cust_phone"/>
    </class>
</hibernate-mapping>

6.数据库连接配置hibernate.cfg.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC
    "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
    "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
    <session-factory>
        <!--配置SQLServer连接属性 -->
        <!-- 第一步配置方言 -->
        <property name="dialect">org.hibernate.dialect.SQLServerDialect</property>
        <property name="connection.driver_class">com.microsoft.sqlserver.jdbc.SQLServerDriver</property>
        <property name="connection.url">jdbc:sqlserver://localhost:1433;databaseName=hibernate</property>
        <property name="connection.username">sa</property>
        <property name="connection.password">123456</property>
        <!--在控制台显示SQL语句 -->
        <property name="show_sqlserver">true</property>
        <!--根据需要自动生成、更新数据表 -->
        <property name="hbm2ddl.auto">update</property>
        <property name="myeclipse.connection.profile">sqlserver</property>
        <!--注册所有ORM映射文件 -->
        <mapping resource="com/sqlserver/domain/Customer.hbm.xml" />
    </session-factory>
</hibernate-configuration>

7.测试

package com.ahabest.test;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;
import com.sqlserver.domain.Customer;
public class HibrenateTest {
    public static void main(String args[]) {
            //加载配置文件
            Configuration configure = new Configuration().configure();
            //创建sessionfactory连接池
            SessionFactory sessionFactory = configure.buildSessionFactory();
            //获取sessionjdbc连接对象
            Session session = sessionFactory.openSession();

            Customer customer = new Customer();
            customer.setCust_name("aa");
            customer.setCust_source("aa");
            customer.setCust_industry("dsd");
            customer.setCust_level("2");
            customer.setCust_phone("132323333");
            // 保存
            session.save(customer);
            //释放资源
            session.close();
            sessionFactory.close();
        }
}
