第一步:下載Hibernate5的運行環境mysql
https://sourceforge.net/projects/hibernate/files/hibernate-orm/sql
第二步:在數據庫建立表數據庫
Create database hibernate_day01; Use hibernate_day01; CREATE TABLE `cst_customer` ( `cust_id` bigint(32) NOT NULL AUTO_INCREMENT COMMENT '客戶編號(主鍵)', `cust_name` varchar(32) NOT NULL COMMENT '客戶名稱(公司名稱)', `cust_user_id` bigint(32) DEFAULT NULL COMMENT '負責人id', `cust_create_id` bigint(32) DEFAULT NULL COMMENT '建立人id', `cust_source` varchar(32) DEFAULT NULL COMMENT '客戶信息來源', `cust_industry` varchar(32) DEFAULT NULL COMMENT '客戶所屬行業', `cust_level` varchar(32) DEFAULT NULL COMMENT '客戶級別', `cust_linkman` varchar(64) DEFAULT NULL COMMENT '聯繫人', `cust_phone` varchar(64) DEFAULT NULL COMMENT '固定電話', `cust_mobile` varchar(16) DEFAULT NULL COMMENT '移動電話', PRIMARY KEY (`cust_id`) ) ENGINE=InnoDB AUTO_INCREMENT=94 DEFAULT CHARSET=utf8;
第三步:搭建Hibernate的開發環境session
建立WEB工程而且引入Hibernate所須要的包app
MySQL的驅動jar包
Hibernate開發須要的jar包(/lib/required/全部jar包)
日誌jar包(資料/jar包/log4j/全部jar包)

第四步:編寫JavaBean實體類
dom
public class Customer { private Long cust_id; private String cust_name; private Long cust_user_id; private Long cust_create_id; private String cust_source; private String cust_industry; private String cust_level; private String cust_linkman; private String cust_phone; private String cust_mobile; // 省略get和set方法 }
第五步:建立類與表結構的映射測試
<?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.itheima.domain.Customer" table="cst_customer"> <id name="cust_id" column="cust_id"> <generator class="native"/> </id> <property name="cust_name" column="cust_name"/> <property name="cust_user_id" column="cust_user_id"/> <property name="cust_create_id" column="cust_create_id"/> <property name="cust_source" column="cust_source"/> <property name="cust_industry" column="cust_industry"/> <property name="cust_level" column="cust_level"/> <property name="cust_linkman" column="cust_linkman"/> <property name="cust_phone" column="cust_phone"/> <property name="cust_mobile" column="cust_mobile"/> </class> </hibernate-mapping>
第六步:編寫Hibernate核心的配置文件ui
<?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> <property name="hibernate.connection.url">jdbc:mysql:///hibernate_day01</property> <property name="hibernate.connection.username">root</property> <property name="hibernate.connection.password">root</property> <property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property> <mapping resource="com/itheima/domain/Customer.hbm.xml"/> </session-factory> </hibernate-configuration>
第七步:編寫Hibernate入門代碼url
/** * 測試保存客戶 */ @Test public void testSave(){ // 先加載配置文件 Configuration config = new Configuration(); // 默認加載src目錄下的配置文件 config.configure(); // 建立SessionFactory對象 SessionFactory factory = config.buildSessionFactory(); // 建立session對象 Session session = factory.openSession(); // 開啓事務 Transaction tr = session.beginTransaction(); // 編寫保存代碼 Customer c = new Customer(); // c.setCust_id(cust_id); 已經自動遞增 c.setCust_name("測試名稱"); c.setCust_mobile("110"); // 保存客戶 session.save(c); // 提交事務 tr.commit(); // 釋放資源 session.close(); factory.close(); }
