1.创建一个普通的java项目
2.加入Hibernate所有的jar包
3.建立包名com.bjpowernode.hibernate
4.建立实体类User.java
package com.bjpowernode.hibernate; import java.util.Date; public class User { private String id; private String name; private String password; private Date createTime; private Date expireTime; public String getId() { return id; } public void setId(String id) { this.id = id; } public String getName() { return name; } public void setName(String name) { this.name = name; } public String getPassword() { return password; } public void setPassword(String password) { this.password = password; } public Date getCreateTime() { return createTime; } public void setCreateTime(Date createTime) { this.createTime = createTime; } public Date getExpireTime() { return expireTime; } public void setExpireTime(Date expireTime) { this.expireTime = expireTime; } }
5.提供User.hbm.xml文件,完成对User实体类的映射(和User.java在同一目录)
<?xml version="1.0"?> <!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.bjpowernode.hibernate.User"> <id name="id"> <generator class="uuid"></generator> </id> <property name="name"></property> <property name="password"></property> <property name="createTime"></property> <property name="expireTime"></property> </class> </hibernate-mapping>
6.提供hibernate.cfg.xml文件,把User.hbm.xml文件加入(hibernate.cfg.xml放置的src文件下)
<!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://hibernate.sourceforge.net/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://172.16.100.10:3306/hibernate_first?useUnicode=true&characterEncoding=GBK</property> <property name="hibernate.connection.username">hibernate</property> <property name="hibernate.connection.password">hibernate</property> <property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property> <property name="hibernate.show_sql">true</property> <mapping resource="com/bjpowernode/hibernate/User.hbm.xml"/> <mapping resource="com/bjpowernode/hibernate/Student.hbm.xml"/> </session-factory> </hibernate-configuration>
7.编写工具类ExoprtDB.java,将hbm生成ddl
package com.bjpowernode.hibernate; import org.hibernate.cfg.Configuration; import org.hibernate.tool.hbm2ddl.SchemaExport; public class ExportDB { public static void main(String[] args){ Configuration cfg = new Configuration().configure(); SchemaExport export = new SchemaExport(cfg); export.create(true, true); } }
8.建立客户端类Client,添加用户数据到mysql
package com.bjpowernode.hibernate; import java.util.Date; import org.hibernate.Session; import org.hibernate.SessionFactory; import org.hibernate.cfg.Configuration; public class Client { public static void main(String[] args){ Configuration cfg = new Configuration().configure(); SessionFactory factory = cfg.buildSessionFactory(); Session session = null; try{ session = factory.openSession(); session.beginTransaction(); User user = new User(); user.setName("张三"); user.setPassword("123"); user.setCreateTime(new Date()); user.setExpireTime(new Date()); session.save(user); session.getTransaction().commit(); }catch (Exception e){ e.printStackTrace(); session.getTransaction().rollback(); } finally { if(session != null && session.isOpen()){ session.close(); } } } }
9.项目目录树
