Pretty Faces 多个注解，加载的是哪一个？

Question

我在托管 Bean 上有多个 PrettyFaces 注释，如何确定页面从哪个入口点加载而不查看传递的参数？

import com.ocpsoft.pretty.faces.annotation.URLAction;
import com.ocpsoft.pretty.faces.annotation.URLMapping;
import com.ocpsoft.pretty.faces.annotation.URLMappings;

@ManagedBean(name = "bean")
    @ViewScoped
    @URLMappings(mappings = {
            @URLMapping(id = "addObject", pattern = "add/type-#{bean.type}", viewId = "/views/object.jsf" ),
            @URLMapping(id = "editObject", pattern = "edit/#{bean.objId}", viewId = "/views/object.jsf")
    })
    public class Bean implements Serializable { 
        private Long type;
        private Long objId;

        @URLAction(onPostback = false)
        public void load() {
                if(objId!=null){
                    //edit mode
                }else{
                    // add mode
                }
        }       
        // getters / setters
    }

您可以像这样使用PrettyContext 访问当前映射的ID：

String id = PrettyContext.getCurrentInstance().getCurrentMapping().getId();
