restful+spring的一些问题

[synized]

public class ExhibitionExhibitsListByExhibitsResource extends ServerResource
        implements IExhibitionExhibitsResource {

    private IExhibitionExhibitsMapper exhibitionExhibitsMapper = null;
    private Long exhibitsId = null;
    @Override
    public void setExhibitionExhibitsMapper(
            IExhibitionExhibitsMapper exhibitionExhibitsMapper) {
        this.exhibitionExhibitsMapper = exhibitionExhibitsMapper;
    }
    @Override
    public void setExhibitionExhibitsDao(IExhibitionExhibitsDao dao) {
        // TODO Auto-generated method stub
    }

    public ExhibitionExhibitsListByExhibitsResource() {
        super.getVariants().add(new Variant(MediaType.TEXT_PLAIN));
    }

    @Override
    public void doInit() {
        if (CheckHelper.objectIsNull(super.getRequestAttributes().get(
                "exhibitsId"))) {
            return;
        } else {
            this.exhibitsId = Long.valueOf(super.getRequestAttributes()
                    .get("exhibitsId").toString());
        }
    }
    @Override
    public Representation get(Variant variant) {

        List<TbExhibitionExhibits> proList = this.exhibitionExhibitsMapper
                .selectListExhibitionExhibitsByExhibitsId(this.exhibitsId
                        .intValue());
        List<ExhibitionExhibitsRo> proRo = new ArrayList<ExhibitionExhibitsRo>();
        for (TbExhibitionExhibits type : proList) {
            proRo.add(new ExhibitionExhibitsRo(type));
        }
        JSONArray array = JSONArray.fromObject(proRo);
        return new StringRepresentation(array.toString());
    }
}

上面是一个resourse 已在spirng3配置文件中配置了路径

   <entry key="/exhibitionExhibits/{exhibitsId}">
                    <bean class="org.restlet.ext.spring.SpringFinder">
                        <lookup-method name="create" bean="exhibitionExhibitsListByExhibitsResource" />
                    </bean>
                </entry>

我想在另一个resource中调用这个resource中的get方法改如何调用??
