不允许在视图中再次引用同一个视图，因为这种循环性使得实体视图必须变得可变，或者引入某种惰性代理。
考虑一下您希望如何将响应建模为JSON，实体视图Map将自然地遵循该模型，例如类似于以下内容：

@EntityView(Location.class)
public interface LocationIdView {
    @IdMapping
    int getId();
}
@EntityView(Location.class)
public interface LocationView extends LocationIdView {
    String getName();
    LocationIdView getParent();
}

或

@EntityView(Location.class)
public interface LocationIdView {
    @IdMapping
    int getId();
}
@EntityView(Location.class)
public interface LocationBaseView<T extends LocationIdView> extends LocationIdView {
    String getName();
    T getParent();
}
@EntityView(Location.class)
public interface LocationView extends LocationBaseView<CountryLocationView> {
}

@EntityView(Location.class)
public interface CountryLocationView extends LocationBaseView<ContinentLocationView> {
}

@EntityView(Location.class)
public interface ContinentLocationView extends LocationBaseView<LocationIdView> {
}
