一、结构

二、代码

1.Client.java:

package com.example.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) {

//读取配置文件

Configuration cfg = new Configuration().configure();

SessionFactory factory = cfg.buildSessionFactory();

Session session = null;

try{

session = factory.openSession();

//开启事务

session.beginTransaction();

Dog user = new Dog();

user.setUsername("hj");

user.setPassword("777");

user.setCreateTime(new Date());

user.setExpireTime(new Date());

session.save(user);

//提交事务

session.getTransaction().commit();

}catch(Exception e){

e.printStackTrace();

//回滚事务

session.getTransaction().rollback();

}finally{

if(session != null){

if(session.isOpen()){

//关闭session

session.close();

}

2.Dog.java:

package com.example.hibernate;

import java.util.Date;

public class Dog {

private String id;

private String username;

private String password;

private Date createTime;

private Date expireTime;

public String getId() {

return id;

}

public void setId(String id) {

this.id = id;

}

public String getUsername() {

return username;

}

public void setUsername(String userName) {

this.username = userName;

}

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;

}

3.ExportDB.java

package com.example.hibernate;

import org.hibernate.cfg.Configuration;

import org.hibernate.tool.hbm2ddl.SchemaExport;

public class ExportDB {

public static void main(String[] args) {

//默认读取hibernate.cfg.xml文件

Configuration cfr = new Configuration().configure();

SchemaExport export = new SchemaExport(cfr);

export.create(true, true);

}

4.Dog.hbm.xml:

<?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.example.hibernate.Dog">
<id name="id">
<generator class="uuid"/>
</id>
<property name="username"/>
<property name="password"/>
<property name="createTime"/>
<property name="expireTime"/>
</class>
</hibernate-mapping>

5.hibernate.cfg.xml

<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

<hibernate-configuration>

<property name="hibernate.connection.username">sys as sysdba</property>

<property name="hibernate.connection.password">111111</property>

<property name="hibernate.dialect">org.hibernate.dialect.Oracle10gDialect</property>

<mapping resource="com/example/hibernate/Dog.hbm.xml"/>
</session-factory>
</hibernate-configuration>
