Hibernate如何映射Map <Object，String>

我有一个使用Hibernate进行持久化的应用程序，我试图映射一个Map，但我得到一些错误： “IllegalArgumentException”和“integrity constraint violation：foreign关键不采取行动”Hibernate如何映射Map <Object，String>

public class Binding{ 
@OneToMany 
private List<Register> registerRef; 
@OneToMany 
private Map<Field, String> fields; 
// getter, setter, put and remove method 
}

映射文件是：

<list name="registerRef" cascade="all"> 
     <key column="BINDING_ID"/> 
     <list-index column="REGISTER_POSITION"/> 
     <one-to-many class="ic2doc2.model.Register"/> 
    </list> 

    <map name="fields" table="FIELD_VALUE" cascade="all, delete-orphan"> 
     <key column="BIND_FV_ID"/> 
     <index column="VAL" type="string" /> 
     <many-to-many class="ic2doc2.model.Field" column="FIELD_ID"></many-to-many> 
    </map>

和班级组织的结合LIS：

public class Register{ 
...................... 
@OneToMany 
private List<Binding> bindings; 
// getter, setter, add and remove method

和他的映射：

<list name="bindings" cascade="all, delete-orphan"> 
     <key column="BINDING_ID"/> 
     <list-index column="BINDING_POSITION"/> 
     <one-to-many class="ic2doc2.model.Binding"/> 
    </list>

错误日志：

我添加的错误日志。我认为错误是由于映射结合的方式，应用程序运行时，一切都很好，但是当我试图重新启动，数据不对应以前的情况 – nixbug

我终于找到了一种方法，使工作

<list name="registerRef" cascade="all"> 
     <key column="BINDING_REGISTER_ID"/> 
     <list-index column="REGISTER_POSITION"/> 
     <many-to-many class="Register"/> 
    </list> 

    <map name="fields" table ="FIELD_VALUE" > 
     <key column = "BIND_FILD_VALUE_ID"/> 
     <map-key-many-to-many column="FIELD" class="Field"/> 
     <element type="string" column="value" /> 
    </map>

从休眠DOC：“使用Hibernate映射文件存在等价的概念到被描述的注释。你必须使用，并<复合地图键>。 <地图键>用于任何基本型，<地图键一对多一对多>用于实体参照和用于复合型。 “
