有两个表，一对多，主表主键包括4个字段，主表主键也是子表的主键
主表：
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 2.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-2.0.dtd">
<hibernate-mapping>
<class name="com.longtop.oa.bean.OutstandingAchievementBean" table="RY_YJKH">
<composite-id>
<key-property name="year" column="kh_nd" />
<key-property name="month" column="kh_yf" />
<key-property name="object" column="kh_dx" type="string" length="40"/>
<key-property name="type" column="kh_dxfl" />
</composite-id>
<property name="fraction" column="kh_kf" />
</class>
</hibernate-mapping>
类
package com.longtop.oa.bean;

import java.io.Serializable;

public String toString() {

}

public boolean equals(Object other) {

OutstandingAchievementBean castOther = (OutstandingAchievementBean) other;
return new EqualsBuilder()

public int hashCode() {

}
子表：

}

public int hashCode() {
return new HashCodeBuilder()

.append(getId())

}
当用以下类插入数据时
private void testAdd()
  {
    OutstandingAchievementBean oab = new OutstandingAchievementBean();
    oab.setYear(2004);
    oab.setMonth(10);
    oab.setObject("abc");
    oab.setType(1);
    oab=new OutstandingAchievement().findBeanById(oab);

    FractionDetailBean fdb=new FractionDetailBean(oab,"1");
    fdb.setNumber(1);
    fdb.setUnitfraction(2d);
    fdb.setId("1");
    fdb.setReason("");
    fdb.setRemark("");
    new FractionDetail().addFractionDetail(fdb);

  }
