基础配置hibernate 项目

Event.java

如下：

package com.zixue.bean;

import java.util.Date;

public class Event {

private int id;

private String title;

private Date date;

public int getId() {

return id;

}

public void setId(int id) {

this.id = id;

}

public String getTitle() {

return title;

}

public void setTitle(String title) {

this.title = title;

}

public Date getDate() {

return date;

}

public void setDate(Date date) {

this.date = date;

}

}

相应的配置如下：

event.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.zixue.bean.Event" table="EVENTS">

<id name="id" column="EVENT_ID">

<generator class="native"/>

</id>

<!-- type="timestamp"是指要映射到，数据库中的字段类型，如果不指定，映射文件会自动将java类型，转换到数据库中的类型（有些不匹配） -->

<property name="date" type="timestamp" column="EVENT_DATE"/>

<property name="title"/>

</class>

</hibernate-mapping>

然后是hibernate.cfg.xml的配置

<?xml version='1.0' encoding='utf-8'?>

<!DOCTYPE hibernate-configuration PUBLIC

"-//Hibernate/Hibernate Configuration DTD 3.0//EN"

"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

<hibernate-configuration>

<session-factory>

<!-- Database connection settings -->

<property name="connection.driver_class">com.mysql.jdbc.Driver</property>

<property name="connection.url">jdbc:mysql://localhost/hibernate</property>

<property name="connection.username">root</property>

<property name="connection.password">123456</property>

<!-- JDBC connection pool (use the built-in) -->

<property name="connection.pool_size">1</property>

<!-- SQL dialect -->

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

<!-- Enable Hibernate's automatic session context management -->

<property name="current_session_context_class">thread</property>

<!-- Disable the second-level cache -->

<property name="cache.provider_class">org.hibernate.cache.NoCacheProvider</property>

<!-- Echo all executed SQL to stdout -->

<property name="show_sql">true</property>

<!-- 根据需要自动创建数据库 -->

<!-- Drop and re-create the database schema on startup -->

<property name="hbm2ddl.auto">update</property>

<mapping resource="com/zixue/bean/event.hb.xml"/>

<!-- <mapping class="com.bjsxt.hibernate.Teacher"/>-->

</session-factory>

</hibernate-configuration>

配置结束，然后就是测试

package com.zixue.bean;

import org.hibernate.Session;

import org.hibernate.SessionFactory;

import org.hibernate.cfg.AnnotationConfiguration;

import org.hibernate.cfg.Configuration;

import org.hibernate.tool.hbm2ddl.SchemaExport;

public class Test {

public static void main(String args[]){

Event e=new Event();

SessionFactory sessionFactory = new AnnotationConfiguration().configure().buildSessionFactory();

Session session = sessionFactory.getCurrentSession();

session.beginTransaction();

session.save(e);

session.getTransaction().commit();

}

}
