问题描述

我想在子对象和父对象之间的类中使用双向导航方法。
IDREF在我的情况下是不够的,因为我不想指定父的le id。从这样的xsd可以清楚地看到

i would like to have bidirectional navigation methods in classes between child object and parent object.IDREF is not enough in my case because I don't want to specify le id of parent.to be clear, from an xsd like that:

<complexType name="A">
    <xs:sequence>
        <element name="b" type="B" minOccurs="0" maxOccurs="unbounded"></element>
    </xs:sequence>
    <attribute name="id" type="ID"></attribute>
</complexType>
<complexType name="B">
    <attribute name="id" type="ID"></attribute>
</complexType>

我希望课程如下:

class A {
    ...
    public List<B> getB() { ...}
    ...
   }
class B {
    ...
    public A getA() {
    ...
}

我的xml必须如下所示:

and my xml must looks like this:

<a id="a1">
    <b id="b1"/>
    <b id="b2"/>
    ...
</a>

在unmarshal之后,我希望能够将A导航到Bs并从B导航到A(通过b.getA())!!
这是一个非常基本的功能,但我找不到一种简单的方法来实现这一目标...

After unmarshal, I would like to be able to navigate A to Bs AND from B to A (via b.getA()) !!It a very basic feature, but I don't find a simple way to achieve that ...

任何想法??

提前致谢

推荐答案

您可以 在Unmarshal之后无效(Unmarshaller,Object parent)被调用...好吧,在解组并根据需要设置对象树。

You can create a method void afterUnmarshal(Unmarshaller, Object parent) that gets called... well, after unmarshalling and set up your object tree as you need it.
