@Controller
    public class BaseController { 
    
        public static final String FOODIE_SHOPCART = "shopcart";
    
        public static final Integer COMMON_PAGE_SIZE = 10;
        public static final Integer PAGE_SIZE = 20;
    
        // 支付中心的调用地址
        String paymentUrl = "http://payment.t.mukewang.com/foodie-payment/payment/createMerchantOrder";		// produce
    
        // 微信支付成功 -> 支付中心 -> 
        // |-> 回调通知的url
        String payReturnUrl = "http://api.z.mukewang.com/foodie-dev-api/orders/notifyMerchantOrderPaid";

# 向支付中心发送商户订单 #

*  创建配置中心：

import org.springframework.boot.web.client.RestTemplateBuilder;
    import org.springframework.context.annotation.Bean;
    import org.springframework.context.annotation.Configuration;
    import org.springframework.web.client.RestTemplate;
    import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
    import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;
    
    @Configuration
    public class WebMvcConfig implements WebMvcConfigurer { 
    
        // 实现静态资源的映射
        @Override
        public void addResourceHandlers(ResourceHandlerRegistry registry) { 
            registry.addResourceHandler("/**")
                    .addResourceLocations("classpath:/META-INF/resources/")  // 映射swagger2
                    .addResourceLocations("file:/workspaces/images/");  // 映射本地静态资源
        }
    
        @Bean
        public RestTemplate restTemplate(RestTemplateBuilder builder) { 
            return builder.build();
        }
    
    }

*  controller层调用：

@ApiOperation(value = "用户下单", notes = "用户下单", httpMethod = "POST")
        @PostMapping("/create")
        public ZCWJSONResult create(
                @RequestBody SubmitOrderBO submitOrderBO,
                HttpServletRequest request,
                HttpServletResponse response) { 
    
            if (submitOrderBO.getPayMethod() != PayMethod.WEIXIN.type
                && submitOrderBO.getPayMethod() != PayMethod.ALIPAY.type ) { 
                return ZCWJSONResult.errorMsg("支付方式不支持！");
            }
    
    // System.out.println(submitOrderBO.toString());
    
            // 1. 创建订单
            OrderVO orderVO = orderService.createOrder(submitOrderBO);
            String orderId = orderVO.getOrderId();
    
            // 2. 创建订单以后，移除购物车中已结算（已提交）的商品
            /** * 1001 * 2002 -> 用户购买 * 3003 -> 用户购买 * 4004 */
            // TODO 整合redis之后，完善购物车中的已结算商品清除，并且同步到前端的cookie
    // CookieUtils.setCookie(request, response, FOODIE_SHOPCART, "", true);
    
            // 3. 向支付中心发送当前订单，用于保存支付中心的订单数据
            MerchantOrdersVO merchantOrdersVO = orderVO.getMerchantOrdersVO();
            merchantOrdersVO.setReturnUrl(payReturnUrl);
    
            // 为了方便测试购买，所以所有的支付金额都统一改为1分钱
            merchantOrdersVO.setAmount(1);
    
            HttpHeaders headers = new HttpHeaders();
            headers.setContentType(MediaType.APPLICATION_JSON);
            headers.add("zcwUserId","zcw");
            headers.add("password","zcw");
    
            HttpEntity<MerchantOrdersVO> entity =
                    new HttpEntity<>(merchantOrdersVO, headers);
    
            ResponseEntity<ZCWJSONResult> responseEntity =
                    restTemplate.postForEntity(paymentUrl,
                                                entity,
                            ZCWJSONResult.class);
            ZCWJSONResult paymentResult = responseEntity.getBody();
            if (paymentResult.getStatus() != 200) { 
                logger.error("发送错误：{}", paymentResult.getMsg());
                return ZCWJSONResult.errorMsg("支付中心订单创建失败，请联系管理员！");
            }
    
            return ZCWJSONResult.ok(orderId);
        }
