在这个章节，我们会将一些文本常量独立出一个资源文件

这样的话，可以方便这些文本常量被翻译成任意的语言

这种国际化的操作，我们一般命名为i18n

新建一个文件i18n.properties

webapp/i18n/i18n.properties (New)

showHelloButtonText=Say Hello
helloMsg=Hello {0}

接着我们将这些常量，绑定到Controller.js

controller/App.controller.js

sap.ui.define([
   "sap/ui/core/mvc/Controller",
   "sap/m/MessageToast",
   "sap/ui/model/json/JSONModel",
   "sap/ui/model/resource/ResourceModel"
], (Controller, MessageToast, JSONModel, ResourceModel) => {
   "use strict";

   return Controller.extend("ui5.walkthrough.controller.App", {
     onInit() {
         // set data model on view
         const oData = {
            recipient : {
               name : "World"
            }
         };
         const oModel = new JSONModel(oData);
         this.getView().setModel(oModel);

         // set i18n model on view
         const i18nModel = new ResourceModel({
            bundleName: "ui5.walkthrough.i18n.i18n"
         });
         this.getView().setModel(i18nModel, "i18n");
      },

      onShowHello() {
         // read msg from i18n model
         const oBundle = this.getView().getModel("i18n").getResourceBundle();
         const sRecipient = this.getView().getModel().getProperty("/recipient/name");
         const sMsg = oBundle.getText("helloMsg", [sRecipient]);

         // show message
         MessageToast.show(sMsg);
      }
   });
});

另外将view.xml中的常量文本替代

webapp/view/App.view.xml

<mvc:View
   controllerName="ui5.walkthrough.controller.App"
   xmlns="sap.m"
   xmlns:mvc="sap.ui.core.mvc">
   <Button
      text="{i18n>showHelloButtonText}"
      press=".onShowHello"/>
   <Input
      value="{/recipient/name}"
      description="Hello {/recipient/name}"
      valueLiveUpdate="true"
      width="60%"/>
</mvc:View>
