我创建了一个使用Hibernate进行持久化的应用程序，我尝试映射映射，但出现了一些错误： “IllegalArgumentException”和“完整性约束冲突：外键无操作”

提前感谢您的回答

我终于找到了一种方法让它发挥作用

    <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>

hibernate文档中：“使用hibernate映射文件存在与所描述注释等效的概念。您必须使用，用于任何基本类型，用于实体引用和复合类型。”

发布错误日志添加了错误日志。我认为错误是由于映射绑定的方式造成的，当应用程序运行正常时，但是当我尝试重新启动时，数据与前面的情况不一致

    <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>

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

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