hibernate 单实体实现 一对多

访问时jsp页面的错误：org.springframework.dao.InvalidDataAccessResourceUsageException: could not initialize a collection

?

原因：???? <set name="childrens" inverse="true"? lazy="false" where="parentFunction=S_FUNCTION_ID">
??????? ?<key>
??????????????? <column name="S_FUNCTION_ID" />
??????????? </key>
??????????? <one-to-many />
??????? </set>

?

注：parentFunction应该为列明

?

正确的为：

? <set name="childrens" inverse="true"? lazy="false" where="PARENT_FUNCTION=S_FUNCTION_ID">
??????? ?<key>
??????????????? <column name="S_FUNCTION_ID" />
??????????? </key>
??????????? <one-to-many />
??????? </set>

?

实体中对应的代码：

private Set<SFunction> childrens =new HashSet<SFunction>(0);
