请大家直接看代码吧.天太热了... 
环境是eclipse ganymede , jdk 6.0, hibernate 3.2, xdoclet1.2.3,ant 1.6.5,mysql5.0

 通过Car 和 Owner的关系可以看出1个Owner可以有0..*个Car

import java.io.Serializable;

/**
 * @hibernate.class table="car"
 * @author Charles King
 *
 */
public class Car implements Serializable{
	private Integer carId;
	
	private String carName;

	/**
	 * @hibernate.id generator-class = "native" column="car_id"
	 * @return
	 */
	public Integer getCarId() {
		return carId;
	}

	public void setCarId(Integer carId) {
		this.carId = carId;
	}

	/**
	 * @hibernate.property column="car_name"
	 * @return
	 */
	public String getCarName() {
		return carName;
	}

	public void setCarName(String carName) {
		this.carName = carName;
	}
	
	
	
}

 

import java.io.Serializable;
import java.util.HashSet;
import java.util.Set;

/**
 * @hibernate.class table = "owner"
 * @author Charles King
 *
 */
public class Owner implements Serializable {

	private Integer ownerId;
	
	private String ownerName;
	
	private Set cars = new HashSet();

	/**
	 * @hibernate.id generator-class = "native" column = "owner_id"
	 * @return
	 */
	public Integer getOwnerId() {
		return ownerId;
	}

	public void setOwnerId(Integer ownerId) {
		this.ownerId = ownerId;
	}

	/**
	 * @hibernate.property column = "owner_name"
	 * @return
	 */
	public String getOwnerName() {
		return ownerName;
	}

	public void setOwnerName(String ownerName) {
		this.ownerName = ownerName;
	}

	/**
	 * @hibernate.set inverse = "true" cascade = "all"
	 * @hibernate.collection-key column = "car_id"
	 * @hibernate.collection-one-to-many class = "net.alp.model.Car"
	 * @return
	 */
	public Set getCars() {
		return cars;
	}

	public void setCars(Set cars) {
		this.cars = cars;
	}
	
	
}

hibernate.properties

hibernate.dialect=org.hibernate.dialect.MySQLDialect
hibernate.connection.url=jdbc:mysql://localhost:3306/test
hibernate.connection.driver_class=com.mysql.jdbc.Driver
hibernate.connection.username=root
hibernate.connection.password=root

 

 表建好了,这是用ant生成的SQL

    alter table car 
        drop 
        foreign key FK17FD49D5CA7DA;

    drop table if exists car;

    drop table if exists owner;

    create table car (
        car_id integer not null auto_increment,
        car_name varchar(255),
        primary key (car_id)
    );

    create table owner (
        owner_id integer not null auto_increment,
        owner_name varchar(255),
        primary key (owner_id)
    );

    alter table car 
        add index FK17FD49D5CA7DA (car_id), 
        add constraint FK17FD49D5CA7DA 
        foreign key (car_id) 
        references owner (owner_id);

 

生成这段的SQL在下面补上

	<!-- ================================= 
          target: gen sql              
         ================================= -->
    <target name="gen sql">
        <mkdir dir="sql"/>
    	<java classname="org.hibernate.tool.hbm2ddl.SchemaExport" fork="true">
    		<classpath refid="runtime.classpath"></classpath>
    		<arg value="--text"/>
    		<arg value="--quiet"/>
    		<arg value="--format"/>
    		<arg value="--output=sql/schema.sql"/>
    		<arg value="--properties=${basedir}/hibernate.properties"/>
    		<arg value="--delimiter=;"/>
    		<arg value="${src.dir}/net/alp/model/*.xml"/>
    	</java>
    </target>

Xdoclet这个项目已经死了很久了(据个人所知,一些Hibernate3.0之后才出现的配置它都不支持的),如果很喜欢Annotation的话,就是用Hibernate官方的东西吧。
