问题描述
我正在研究Hibernate映射，其他一切工作都很好，除了我在获得Hibernate试图将我的对象持久化到系统时的PropertyAccessException。
以下是堆栈跟踪

这里是getter和setter方法的代码
public String getUuid（）{
return uuid;
}
public void setUuid（String uuid）{
this.uuid = uuid;
}
，映射部分为
< id name =uuidtype =java.lang.String>
< column name =UUID/>
< generator class =uuid/>
< / id>
我是hibernate的新手，所以不太清楚到底什么是我的目标类所关注的问题其他类也持续坚持我坚持Destination class
在这方面的任何帮助是非常appricitaed
Edit1
那么这个问题似乎与我在Destination类中以及映射文件中定义的关系有关。
私人设定< PlaceToVisit> placesToVisit = new HashSet< PlaceToVisit>（）;
public Set< PlaceToVisit> getPlacesToVisit（）{
返回placesToVisit;
}
public void setPlacesToVisit（Set< PlaceToVisit> placesToVisit）{
this.placesToVisit = placesToVisit;
}
public void addPlaceToVisit（PlaceToVisit placeToVisit）{
placeToVisit.setDestination（this）;
this.placesToVisit.add（placeToVisit）;
}
以及将文件映射为
< set name =placesToVisittable =PLACETOVISITinverse =falselazy =truecascade =save-update>
< key>
< column name =DESTINATIONID/>
< / key>
<一对多课程=PlaceToVisit/>
< / set>
而我在PlaceToVisit类中有以下内容：
< id name =uuidtype =java.lang.String>
< column name =UUID/>
< generator class =uuid/>
< / id>
< property name =nametype =java.lang.String>
< column name =NAME/>
< / property>
<多对一名称=目的地class =目的地fetch =加入>
< column name =DESTINATION/>
< /多对一>
以及此类的其他getter setter
当我从目标类中删除关联的所有参考时，一切工作正常，但在目标映射文件中添加了任何关系条目，向我展示了上述错误。
这个错误可能是由于其他类型的对象被发现在类型为 Destination 的对象所期望的地方。例如，如果某些其他类通过未经检查的转换偶然添加到 Collection< Destination> 中。

<id name="uuid" type="java.lang.String">
<column name="UUID" />
<generator class="uuid"/>
</id>
i am new to hibernate so not much idea what exactly is the problem my destination class has refrence to few other class which are also getting persist when i am persisting Destination class
any help in this regard is much appricitaed
Edit1
Well the problem seems to be with respect to the relation i have defined in the Destination class as well in the mapping file..
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);
}
as well in mapping file as
<set name="placesToVisit" table="PLACETOVISIT" inverse="false" lazy="true" cascade="save-update">
<key>
<column name="DESTINATIONID" />
</key>
<one-to-many class="PlaceToVisit" />
</set>
while i have following in the PlaceToVisit class
<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>
and other getter setter for this class
when i am removing all refrences of the associations from the destination class everything working fine but adding any relation entry in Destination mapping file showing me the above described error.
解决方案
This error may be caused by the fact that the object of some other type was found where the object of type Destination was expected.
For example, if some other class was accidentially added to Collection<Destination> via unchecked cast.
