我们开发的这个SAP UI5应用需要消费一个OData服务,请求该服务得到一系列采购订单的数据,再显示到UI5应用上。所以需要先申请该OData服务所在的服务器ES5上的用户。

申请链接:

https://register.sapdevcenter...


申请完毕后,可以通过webUI进入该系统。

OData服务的地址:

https://sapes5.sapdevcenter.c...$format=json


登录SAP云平台,创建一个指向ES5的Destination:


打开SAP云平台的WebIDE,新建一个项目,基于template创建一个SAP UI5应用:




右键菜单,新建一个OData服务:

从service catalog的下拉菜单里选择刚刚创建的Destination,能带出该Destination指向的ES5服务器上部署的所有OData服务:

选择采购订单OData服务:

WebIDE会帮我们生成一个UI5应用的骨架,直接点run按钮试着运行:

在Chrome开发者工具里看到OData服务的metadata已经可以成功取回了:

XML视图的实现代码:

<mvc:View controllerName="com.sap.PurchaseOrderApp.controller.Mainview" xmlns:mvc="sap.ui.core.mvc" displayBlock="true" xmlns="sap.m">
    <Shell id="shell">
        <App id="app">
            <pages>
                <Page title="Purchase Orders">
                    <!-- INSERT IN STEP 3 OF THE NEXT TUTORIAL -->
                    <content>
                        <List noDataText="No purchase orders found" items="{/PurchaseOrders}">
                            <StandardListItem type="Navigation" title="{POId}" description="{SupplierName}" press="onClickPO"/>
                        </List>
                    </content>
                </Page>
                <!-- INSERT CODE IN STEP 5.2 HERE -->
            </pages>
        </App>
    </Shell>
</mvc:View>

将上面的xml视图代码实现之后,整个应用的外观如下:

最后通过右键菜单将这个应用从WebIDE部署到SAP云平台:


部署成功:


该应用的controller源代码:

sap.ui.define([
    "sap/ui/core/mvc/Controller"
], function (Controller) {
    "use strict";

    return Controller.extend("com.sap.PurchaseOrderApp.controller.Mainview", {
        onInit: function () {

        }, // INSERT IN STEP 2 OF THE NEXT TUTORIAL
        onClickPO: function (oEvent) {
                var oApp = this.getView().getContent()[0].getApp();
                var sBindingPath = oEvent.getSource().getBindingContext().getPath();
                var oDetailsPage = oApp.getPages()[1].bindElement(sBindingPath);
                oApp.to(oDetailsPage.getId());
            }
            // INSERT CODE IN SUB-STEP 6.2 HERE
    });
});
