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 class="com.tzj.rmp.bean.SFunction" />
        </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 class="com.tzj.rmp.bean.SFunction" />
        </set>

 

实体中对应的代码：

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