1、新建java项目
2、创建User Library(window —— preferences —— Java —— Build Path —— User Libraries),加入如下jar:
* 项目名称/hibernate3.jar
* 项目名称/lib/*.jar
* MySQL jdbc驱动
3、创建hibernate配置文件hibernate.cfg.xml,为了便于调试最好加入log4配置文件
5、定义User类的映射文件User.hbm.xml
6、将User.hbm.xml文件加入到hibernate.cfg.xml文件中
7、编写hbm2ddl工具类,将实体类生成数据库表
8、开发客户端
hibernate.cfg.xml文件中输入标签时不自动提示该有属性的解决方法:
解决办法:
1.添加相关插件,如Myeclipse.安装插件后,有时Myeclipse不能自动识别Hibernate的相关配置文件.
(通常工程没有引入Myeclipse相关组件管理的时候就这样)
2.如果没有认上,为*.cfg.xml设定Associated editors.
设定方法 window->preferences->editors->File Associations. File types中添加*.cfg.xml
Associated editors中选择"MyEclipse Hibernate Config Editor".
2、创建User Library(window —— preferences —— Java —— Build Path —— User Libraries),加入如下jar:
* 项目名称/hibernate3.jar
* 项目名称/lib/*.jar
* MySQL jdbc驱动
3、创建hibernate配置文件hibernate.cfg.xml,为了便于调试最好加入log4配置文件
<hibernate-configuration>
<session-factory>
<property name="hibernate.connection.url">jdbc:mysql://localhost/hibernate-1</property>
<property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
<property name="hibernate.connection.username">root</property>
<property name="hibernate.connection.password">root</property>
<property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property> //方言
<property name="hibernate.show_sql">true</property> //显示sql语句
<mapping resource="com/neusoft/hibernate/User.hbm.xml"/>
</session-factory>
</hibernate-configuration>
4、定义实体类(User.java)package com.neusoft.hibernate;
import java.util.Date;
public class User {
private String id;
private String name;
private String password;
private Date createTime; //创建时间
private Date expireTime; //失效时间
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、定义User类的映射文件User.hbm.xml
<hibernate-mapping>
<class name="com.neusoft.hibernate.User">
<id name="id">
<generator class="uuid"></generator>
</id>
<property name="name"/>
<property name="password"/>
<property name="createTime"/>
<property name="expireTime"/>
</class>
</hibernate-mapping>
6、将User.hbm.xml文件加入到hibernate.cfg.xml文件中
7、编写hbm2ddl工具类,将实体类生成数据库表
package com.neusoft.hibernate;
import org.hibernate.cfg.Configuration;
import org.hibernate.tool.hbm2ddl.SchemaExport;
public class ExportDB {
public static void main(String[] args) {
//读取hibernate.cfg.xml文件
Configuration cfg = new Configuration().configure();
SchemaExport export = new SchemaExport(cfg);
export.create(true, true);
}
}
8、开发客户端
hibernate.cfg.xml文件中输入标签时不自动提示该有属性的解决方法:
解决办法:
1.添加相关插件,如Myeclipse.安装插件后,有时Myeclipse不能自动识别Hibernate的相关配置文件.
(通常工程没有引入Myeclipse相关组件管理的时候就这样)

设定方法 window->preferences->editors->File Associations. File types中添加*.cfg.xml
Associated editors中选择"MyEclipse Hibernate Config Editor".
