我有一个超类Person:

public class Person {
    public abstract Type getType();
}

我有2个子类:

public class JuridicalPerson extends Person {
    public Type getType() {
        return Type.JP;
    }
    public List<JuridicalBelong> getJuridicalBelongs() {
        return juridicalBelongs;
    }
}

public class NaturalPerson extends Person {
    public Type getType() {
        return Type.NP;
    }
    public List<NaturalBelong> getNaturalBelongs() {
        return naturalBelongs;
    }
}

JuridicalBelong并NaturalBelong具有不同的属性,不能被子类化.

我将它们放在List<Person>JSF/Facelets中,如下所示:

<ui:repeat value="#{bean.persons}" var="person">
    <h:panelGroup rendered="#{person.type eq 'JP'}">
        <ui:repeat value="#{person.juridicalBelongs}" var="juridicalBelong">
            ...
        </ui:repeat>
    </h:panelGroup>
    <h:panelGroup rendered="#{person.type eq 'NP'}">
        <ui:repeat …
