跟单向关联仅有几处不同:

1从多的一方加入新的属性

package com.cnblogs.hibernate_first;

public class Student {

    private int id;

    private String name;
    
    private Classes classes;

    public Classes getClasses() {
        return classes;
    }

    public void setClasses(Classes classes) {
        this.classes = classes;
    }

    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;
    }

}

2修改xml文件.Classes.hbm.xml

span>mapping PUBLIC
        "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
        "http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd" >
package="com.cnblogs.hibernate_first">
    class name="Classes" table="t_classes">
        class="native">class="com.cnblogs.hibernate_first.Student"/>
        class>

3,修改Student.hbm.xml文件

package="com.cnblogs.hibernate_first">
    class name="Student" table="t_student">
