我正在进行hibernate映射,并且除PropertyAccessException之外,其他所有事情都工作正常,当我试图将对象持久保存到系统中时,我正在获取PropertyAccessException。下面是堆栈跟踪

这是getter和setter方法的代码
public String getUuid() { return uuid; } public void setUuid(String uuid) { this.uuid = uuid; }
映射部分是
<id name="uuid" type="java.lang.String"> <column name="UUID" /> <generator class="uuid"/> </id>
我是新来的hibernate者,所以没有太多的想法,我的目的地班级到底对其他几个班级有什么影响,而当我坚持目的地班级时,其他班级也变得持久了
在这方面的任何帮助都是可取的
编辑1
嗯,问题似乎与我在Destination类以及映射文件中定义的关系有关。
private Set<PlaceToVisit> placesToVisit=new HashSet<PlaceToVisit>(); public Set<PlaceToVisit> getPlacesToVisit() { return placesToVisit; } public void setPlacesToVisit(Set<PlaceToVisit> placesToVisit) { this.placesToVisit = placesToVisit; } public void addPlaceToVisit(PlaceToVisit placeToVisit){ placeToVisit.setDestination(this); this.placesToVisit.add(placeToVisit); }
以及在映射文件中
<set name="placesToVisit" table="PLACETOVISIT" inverse="false" lazy="true" cascade="save-update"> <key> <column name="DESTINATIONID" /> </key> <one-to-many class="PlaceToVisit" /> </set>
当我在PlaceToVisit类中关注时
<id name="uuid" type="java.lang.String"> <column name="UUID" /> <generator class="uuid"/> </id> <property name="name" type="java.lang.String"> <column name="NAME" /> </property> <many-to-one name="destination" class="Destination" fetch="join"> <column name="DESTINATION" /> </many-to-one>
和本课程的其他获取方法
当我从目标类中删除关联的所有引用时,一切正常,但是在目标映射文件中添加任何关系条目,向我显示上述错误。
该错误可能是由于以下事实导致的:找到了其他类型的对象,而该对象是该类型的对象Destination所期望的。
Destination
例如,如果Collection<Destination>通过未经检查的转换意外添加了其他一些类。
Collection<Destination>
