SAP Spartacus注入自定义的CurrentProduc

新建一个MyCurrentProductService，返回一个硬编码的产品主数据：

完整源代码如下：

import { Product, ProductScope } from '@spartacus/core';
import { Observable, of } from 'rxjs';

const PRODUCT: Product = {
    code: '300938',
    name: 'Jerry hard code value',
    summary: 'Jerry hard code value.',
    price: {
        formattedValue: '$10000',
        currencyIso: 'USD',
        // "priceType": "BUY",
        value: 10000
    },
    images: {
        PRIMARY: {
            zoom: {
                altText: 'Photosmart E317 Digital Camera',
                format: 'zoom',
                // : "PRIMARY",

            },
            product: {
                altText: 'Photosmart E317 Digital Camera',
                format: 'product',

    ],

};

export class MyCurrentProductService {
    getProduct(scopes?: (ProductScope | string)[] | ProductScope | string): Observable<Product> {
        console.log('My product service is called!');
        return of(PRODUCT);
    }
}

在app module里，用MyCurrentProductService覆盖掉SAP Spartacus标准的CurrentProductService：

运行时测试，我任意点开一个产品主数据的明细页面，都会调用我自己的CurrentProductService，显示硬编码的数据：
