1. 创建一个实体类,对应数据库的每个表,User.java
2. 创建实体类相对应的映射文件,User.hbm.xml
3. 创建Hibernate相对应的配置文件Hibernate.cfg.xml或者Hibernate.properties
4. 创建数据库类,ExportDB.java
附源代码：
User.java
package com.hibernate01;
public class User {
private int id;
private String username;
private String password;
private String address;
public int getId() {
return id;
}
public void setId(int 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 String getAddress() {
return address;
}
public void setAddress(String address) {
this.address = address;
}
}
User.hbm.xml
<?xml version="1.0"?>

ExportDB.java
package com.hibernate01;

public class ExportDB {

public static void main(String[] args) {

export.create(true, true);

}

</session-factory>
</hibernate-configuration>
测试环境：Eclipse3.4+Hibernate3.3+Sql Server2005（Sql2008，Sql2000）
如果Sql Server数据库不是默认实例,需要修改jdbc:sqlserver://teng;databaseName=hibernate;selectMethod=Cursor;为jdbc:sqlserver://teng\sql2008;databaseName=hibernate;selectMethod=Cursor;
其中Sql2008为一个实例名。
Sql2000，Sql2008必须在配置管理器中开启
