Hibernate教程01

如何创建第一个hibernate项目

1.创建项目

2.导包

3.写配置文件

4.创建实体类和数据库

5.创建测试类

以上是需要导入的包

创建一个Customer.hbm.xml文件

<?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">
	<!--一般这个头是同事写好了直接复制过来，尽量不要自己去写-->
	
	<!-- 配置表与实体对象的关系 -->
	
	<hibernate-mapping>
		<class name="com.tz.domain.Customer" table="cst_customer">   <!-- 复制Customer完整的类名到name,把表名填到table -->
			<id name="cust_id" column="cust_id">						 <!-- 把表中的cust_id复制到name,column列名也是这个   -->	
				<generator class="native"></generator>		 <!-- class中填写native先不介绍 -->
			</id>
			<property name="cust_name" column="cust_name"></property>		 <!-- 把实体类中的属性复制进来,属性和列名一样 -->	 
			<property name="cust_source" column="cust_source"></property>	 <!-- 属性相当于数据库中的字段-->	 
			<property name="cust_industry" column="cust_industry"></property>		 
			<property name="cust_level" column="cust_level"></property>		 
			<property name="cust_linkman" column="cust_linkman"></property>		 
			<property name="cust_phone" column="cust_phone"></property>		 
			<property name="cust_mobile" column="cust_mobile"></property>		 
		</class>
	</hibernate-mapping>

再创建一个hibernate.cfg.xml文件

<?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>
				<property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>	<!-- 驱动 -->
				<property name="hibernate.connection.url">jdbc:mysql:///nice</property>			<!-- 地址 三个斜杠可以省略localhost-->
				<property name="hibernate.connection.username">root</property>		<!-- 用户名 -->
				<property name="hibernate.connection.password">nice</property>		<!-- 密码 -->
				<property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>	
				<!-- 数据库方言
				不同的数据库中，sql语句略有区别,指定方言可以让hibernate框架生成sql语句时，针对数据库的方言生成
				sql语句都基于sql99标准
				DDL：定义语言 数据库表的增删改查
				DCL: 控制语言 事务 权限
				DML: 操作语言 增删该查
				注意事项:mysql在选择方言时，请选择最短的方言 hibernate.dialect org.hibernate.dialect.MySQLDialect
				-->
				<property name="hibernate.show_sql">true</property>		<!-- 把hibernate生成的sql语句显示在控制台上 -->
				<property name="hibernate.format_sql">true</property>	<!-- 把打印的sql语句格式化	不然sql语句都显示在一行上-->
				<property name="hibernate.hbm2ddl.auto">update</property>
				<mapping resource="com/tz/domain/Customer.hbm.xml"/>
			</session-factory>
		</hibernate-configuration>

创建测试类

package com.tz.test.a_hello;

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.hibernate.cfg.Configuration;
import org.junit.Test;

import com.tz.domain.Customer;

//测试Hibernate框架
public class Demo {
	@Test
	//保存客户
	public void fun1(){
		Configuration conf = new Configuration().configure();
		SessionFactory sessionFactory = conf.bulidSessionFactory();
		Session session = sessionFactory.openSession();
		Transaction tx = session.beginTransaction();
		//-----华丽的分割线-----
		Customer c = new Customer();
		c.setCust_name("潭州教育");
		session.save(c);//执行保存
		//-----华丽的分割线-----
		tx.commit();
		session.close();
		sessionFactory.close();
	}
}

创建实体类

package com.tz.domain;

public class Customer {
	/**
	 * CREATE TABLE `cst_customer` (
  `cust_id` bigint(20) NOT NULL AUTO_INCREMENT,
  `cust_name` varchar(255) DEFAULT NULL,
  `cust_source` varchar(255) DEFAULT NULL,
  `cust_industry` varchar(255) DEFAULT NULL,
  `cust_level` varchar(255) DEFAULT NULL,
  `cust_linkman` varchar(255) DEFAULT NULL,
  `cust_phone` varchar(255) DEFAULT NULL,
  `cust_moblie` varchar(255) DEFAULT NULL,
  `cust_mobile` varchar(255) DEFAULT NULL,
  PRIMARY KEY (`cust_id`)
) ENGINE=InnoDB AUTO_INCREMENT=8 DEFAULT CHARSET=gbk;
	 */
	private Long cust_id;
	
	private String cust_name;
	private String cust_source;
	private String cust_industry;
	private String cust_level;
	private String cust_linkman;
	private String cust_phone;
	private String cust_moblie;
	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_linkman() {
		return cust_linkman;
	}
	public void setCust_linkman(String cust_linkman) {
		this.cust_linkman = cust_linkman;
	}
	public String getCust_phone() {
		return cust_phone;
	}
	public void setCust_phone(String cust_phone) {
		this.cust_phone = cust_phone;
	}
	public String getCust_moblie() {
		return cust_moblie;
	}
	public void setCust_moblie(String cust_moblie) {
		this.cust_moblie = cust_moblie;
	}
	@Override
	public String toString() {
		return "Customer [cust_id=" + cust_id + ", cust_name=" + cust_name + "]";
	}
