3.4.3.1 面向对象-继承与多态
本节为小伙伴们介绍，Function的面向对象的特性：继承与多态； 一、继承 我们在3.4.1【构建第一个Function】一文中伴随模型新增函数和独立类新增函数绑定到模型部分都是在父模型PetShop新增了sayHello的Function，同样其子模型都具备sayHello的Function。因为我们是通过Function的namespace来做依据的，子模型在继承父模型的sayHello函数后会以子模型的编码为namespace，名称则同样为sayHello。 二、多态（举例） oinone的多态，我们只提供覆盖功能，不提供重载，因为oinone相同name和fun的情况下不会去识别参数个数和类型。 Step1 为PetShop新增hello函数 package pro.shushi.pamirs.demo.api.model; …… //import @Model.model(PetShop.MODEL_MODEL) @Model(displayName = "宠物店铺",summary="宠物店铺",labelFields ={"shopName"} ) @Model.Code(sequence = "DATE_ORDERLY_SEQ",prefix = "P",size=6,step=1,initial = 10000,format = "yyyyMMdd") public class PetShop extends AbstractDemoIdModel { public static final String MODEL_MODEL="demo.PetShop"; …… //省略其他代码 @Function(openLevel = FunctionOpenEnum.API) @Function.Advanced(type= FunctionTypeEnum.QUERY) public PetShop sayHello(PetShop shop){ PamirsSession.getMessageHub().info("Hello:"+shop.getShopName()); return shop; } @Function(name = "sayHello2",openLevel = FunctionOpenEnum.API) @Function.Advanced(type= FunctionTypeEnum.QUERY) @Function.fun("sayHello2") public PetShop sayHello(PetShop shop, String s) { PamirsSession.getMessageHub().info("Hello:"+shop.getShopName()+",s:"+s); return shop; } @Function(openLevel = FunctionOpenEnum.API) @Function.Advanced(type= FunctionTypeEnum.QUERY) public PetShop hello(PetShop shop){ PamirsSession.getMessageHub().info("Hello:"+shop.getShopName()); return shop; } } 图3-4-3-1 为PetShop新增hello函数 Step2 为PetShopProxyB新增对应的三个函数 其中PetShopProxyB新增的hello函数，在java中是重载了hello，在代码中new PetShopProxyB()是可以调用父类的sayHello单参方法，也可以调用本类的双参方法。但在oinone的体系中对于PetShopProxyB只有一个可识别的Function就是双参的sayHello package pro.shushi.pamirs.demo.api.proxy; import pro.shushi.pamirs.demo.api.model.PetCatItem; import pro.shushi.pamirs.demo.api.model.PetShop; import pro.shushi.pamirs.meta.annotation.Field; import pro.shushi.pamirs.meta.annotation.Function; import pro.shushi.pamirs.meta.annotation.Model; import pro.shushi.pamirs.meta.api.session.PamirsSession; import pro.shushi.pamirs.meta.enmu.FunctionOpenEnum; import pro.shushi.pamirs.meta.enmu.FunctionTypeEnum; import pro.shushi.pamirs.meta.enmu.ModelTypeEnum; import java.util.List; @Model.model(PetShopProxyB.MODEL_MODEL) @Model.Advanced(type = ModelTypeEnum.PROXY,inherited ={PetShopProxy.MODEL_MODEL,PetShopProxyA.MODEL_MODEL} ) @Model(displayName = "宠物店铺代理模型B",summary="宠物店铺代理模型B") public class PetShopProxyB extends PetShop { public static final String MODEL_MODEL="demo.PetShopProxyB"; @Field.one2many @Field(displayName = "萌猫商品列表") @Field.Relation(relationFields = {"id"},referenceFields = {"shopId"}) private List<PetCatItem> catItems; @Function(openLevel = FunctionOpenEnum.API) @Function.Advanced(type= FunctionTypeEnum.QUERY) public PetShop sayHello(PetShop shop){ PamirsSession.getMessageHub().info("PetShopProxyB Hello:"+shop.getShopName()); return shop; } @Function(name = "sayHello2",openLevel = FunctionOpenEnum.API) @Function.Advanced(type= FunctionTypeEnum.QUERY) @Function.fun("sayHello2") public PetShop sayHello(PetShop shop,String hello){ PamirsSession.getMessageHub().info("PetShopProxyB say:"+hello+","+shop.getShopName()); return shop; } @Function(openLevel = FunctionOpenEnum.API)…

3.5.1 构建第一个Menu
在前面章节中我们也涉及到菜单，因为菜单我们模块就是地图、导航，没有地图、导航就无法畅游模块并进行相关业务操作。在3.3.4【模块的继承】一文关于多表继承的内容就有涉及到菜单的初始化，本文将展开介绍初始化Menu的两种方式分别是：注解式、数据初始化式。 注解式(举例) Step1 分析现有菜单注解 用@UxMenus声明DemoMenus为菜单初始化入口，同时该类在DemoModule配置扫描路径中，那么通过DemoMenus初始化的菜单都挂在demo_core这个模块上。 如果采用这种模式，建议同一个模块的菜单都只配置在一处 package pro.shushi.pamirs.demo.core.init; import pro.shushi.pamirs.boot.base.constants.ViewActionConstants; import pro.shushi.pamirs.boot.base.ux.annotation.action.UxRoute; import pro.shushi.pamirs.boot.base.ux.annotation.navigator.UxMenu; import pro.shushi.pamirs.boot.base.ux.annotation.navigator.UxMenus; import pro.shushi.pamirs.demo.api.model.*; import pro.shushi.pamirs.demo.api.proxy.PetShopProxy; import pro.shushi.pamirs.demo.api.proxy.PetShopProxyA; import pro.shushi.pamirs.demo.api.proxy.PetShopProxyB; @UxMenus public class DemoMenus implements ViewActionConstants { @UxMenu("商店管理")@UxRoute(PetShopProxy.MODEL_MODEL) class PetShopProxyMenu{} @UxMenu("商店管理A")@UxRoute(PetShopProxyA.MODEL_MODEL) class PetShopProxyAMenu{} @UxMenu("商店管理B")@UxRoute(PetShopProxyB.MODEL_MODEL) class PetShopProxyBMenu{} @UxMenu("商品管理")@UxRoute(PetItem.MODEL_MODEL) class ItemMenu{} @UxMenu("宠狗商品")@UxRoute(PetDogItem.MODEL_MODEL) class DogItemMenu{} @UxMenu("萌猫商品")@UxRoute(PetCatItem.MODEL_MODEL) class CatItemMenu{} @UxMenu("宠物品种")@UxRoute(PetType.MODEL_MODEL) class PetTypeMenu{} @UxMenu("萌猫品种")@UxRoute(PetCatType.MODEL_MODEL) class CatTypeMenu{} @UxMenu("宠狗品种")@UxRoute(PetDogType.MODEL_MODEL) class DogTypeMenu{} @UxMenu("宠物达人")@UxRoute(PetTalent.MODEL_MODEL) class PetTalentMenu{} } 图3-5-1-1 菜单注解 Step2 改造现有菜单注解 菜单的层级关系通过@UxMenu的嵌套进行描述 菜单点击效果有三种分别对应不同的Action的类型，关于Action的类型详见3.5.3【Action的类型】一文。 通过@UxRoute定义一个与菜单绑定的viewAction，@UxMenu("创建商店")@UxRoute(value = PetShop.MODEL_MODEL,viewName = "redirectCreatePage",viewType = ViewTypeEnum.FORM)，其中viewName代表视图的name(其默认值为redirectListPage，也就是跳转到列表也)，value代码视图所属模型的编码，viewType代表view类型（其默认值为ViewTypeEnum.TABLE） @UxServer定义一个与菜单绑定的serverAction，@UxMenu("UxServer")@UxServer(model = PetCatItem.MODEL_MODEL,name = "uxServer") ，其中name代表serverAction的name，model或value代码serverAction所属模型的编码 @UxLink定义一个与菜单绑定的UrlAction，@UxMenu("Oinone官网")@UxLink(value = "http://www.oinone.top”,openType= ActionTargetEnum.OPEN_WINDOW) ，其中value为跳转url，openType为打开方式默认为ActionTargetEnum.ROUTER，打开方式有以下几种 ROUTER("router", "页面路由", "页面路由") DIALOG("dialog", "页面弹窗", "页面弹窗") DRAWER("drawer", "打开抽屉", "打开抽屉") OPEN_WINDOW("openWindow", "打开新窗口", "打开新窗口") 配合菜单演示，PetCatItemAction增加一个uxServer的ServerAction package pro.shushi.pamirs.demo.core.action; ……包引用 @Model.model(PetCatItem.MODEL_MODEL) @Component public class PetCatItemAction extends DataStatusBehavior<PetCatItem> { ……省略其他代码 @Action(displayName = "uxServer") public PetCatItem uxServer(PetCatItem data){ PamirsSession.getMessageHub().info("uxServer"); return data; } } 图3-5-1-2 示例代码 新的菜单初始化代码如下 package pro.shushi.pamirs.demo.core.init; import pro.shushi.pamirs.boot.base.constants.ViewActionConstants; import pro.shushi.pamirs.boot.base.enmu.ActionTargetEnum; import pro.shushi.pamirs.boot.base.ux.annotation.action.UxLink; import pro.shushi.pamirs.boot.base.ux.annotation.action.UxRoute; import pro.shushi.pamirs.boot.base.ux.annotation.action.UxServer; import pro.shushi.pamirs.boot.base.ux.annotation.navigator.UxMenu; import pro.shushi.pamirs.boot.base.ux.annotation.navigator.UxMenus; import pro.shushi.pamirs.demo.api.model.*; import pro.shushi.pamirs.demo.api.proxy.PetShopProxy; import pro.shushi.pamirs.demo.api.proxy.PetShopProxyA; import pro.shushi.pamirs.demo.api.proxy.PetShopProxyB; import pro.shushi.pamirs.meta.enmu.ViewTypeEnum; @UxMenus public class DemoMenus implements ViewActionConstants { @UxMenu("商店") class ShopMenu{ @UxMenu("UxServer")@UxServer(model = PetCatItem.MODEL_MODEL,name = "uxServer") class ShopSayHelloMenu{ } @UxMenu("创建商店")@UxRoute(value = PetShop.MODEL_MODEL,viewName = "redirectCreatePage",viewType = ViewTypeEnum.FORM) class ShopCreateMenu{ }…
