二、Hibernate下Hello World Annotaion版 1.创建teacher表 create table teacher(id int primary key , name varchar(20) , title varchar(20)); 2.创建Teacher类,创建对应的Annotation package com.zgy.hibernate.model;import javax.persistence.Entity;i
1.创建teacher表
create table teacher(id int primary key , name varchar(20) , title varchar(20));
2.创建Teacher类,创建对应的Annotation
package com.zgy.hibernate.model; import javax.persistence.Entity; import javax.persistence.Id; @Entity public class Teacher { private int id; private String name; private String title; @Id public int getId() { return id; } public void setId(int id) { this.id = id; } public String getName() { return name; } public void setName(String name) { this.name = name; } public String getTitle() { return title; } public void setTitle(String title) { this.title = title; } }
3.加入相应的hibernate jar 包
4.在hibernate.cfg.xml中添加配置
<?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> <!-- Database connection settings --> <property name="connection.driver_class">com.mysql.jdbc.Driver</property> <property name="connection.url">jdbc:mysql://localhost:3306/hibernate</property> <property name="connection.username">root</property> <property name="connection.password">root</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.internal.NoCacheProvider</property> <!-- Echo all executed SQL to stdout --> <property name="show_sql">t【本文来自鸿网互联 (http://www.68idc.cn)】rue</property> <!-- Drop and re-create the database schema on startup --> <!-- <property name="hbm2ddl.auto">update</property> --> <mapping resource="com/zgy/hibernate/model/Student.hbm.xml"/> <mapping class="com.zgy.hibernate.model.Teacher"/> </session-factory> </hibernate-configuration>
5.测试,查看数据库变化。
