在 Spring Boot 中将整个 Protobuf 消息添加到模型中

发布于 2025-01-16 09:40:34 字数 818 浏览 1 评论 0原文

我开始尝试使用 Spring Boot 以了解它如何在 MVC Web 应用程序中发挥作用。

从高层来看，我们的目标是拥有一个控制器，通过向外部 gRPC 服务器发出请求来处理 GET 请求，该服务器将返回 Order protobuf 消息。 Order 数据将添加到 Model 中，并通过带有 Thymeleaf 的模板提供服务。

我对整个 Spring 框架很陌生，所以这种方法可能是不正确的，但我正在做的是：

@Controller
public class OrderController {

    @GetMapping("/order")
    public String getOrder(@RequestParam(name = "order_number") String orderNumber, Model model) {

        // Code for getting Order proto message from external server here

        model.addAttribute("name", Order.getDate());
        model.addAttribute("total", Order.getTotal());
        model.addAttribute("number", Order.getNumber());
        ....

        return "order";
        
    }
    
}

然而，这看起来相当乏味（特别是对于较大的消息）。我是否缺少一些东西可以让我批量添加这些字段？

I'm starting to play around with Spring Boot to learn how it functions for a MVC web application.

At a high-level the goal is to have a controller that will handle GET requests by issuing a request to an external gRPC server which will return a Order protobuf message. The Order data will be added to the Model and served via a template with Thymeleaf.

I am new to the Spring framework as a whole so the approach is likely incorrect but what I was doing is:

@Controller
public class OrderController {

    @GetMapping("/order")
    public String getOrder(@RequestParam(name = "order_number") String orderNumber, Model model) {

        // Code for getting Order proto message from external server here

        model.addAttribute("name", Order.getDate());
        model.addAttribute("total", Order.getTotal());
        model.addAttribute("number", Order.getNumber());
        ....

        return "order";
        
    }
    
}

However, this seems pretty tedious (especially for larger messages). Is there something I am missing that would allow me to add these fields en-masse?

抱歉，我无法对问题发表评论（SO限制），因此在这里问 - 你不能将订单对象放入模型（而不是单个字段）中并在视图（Thymeleaf）中访问它的字段/方法吗？

在视图中的控制器中

model.addAttribute("order", order);

，我不确定，因为我没有使用过 Thymeleaf，但应该类似于

<span th:text="${order.getName()}" />

Sorry, I cannot comment on question (SO restriction), hence asking here - cannot you just put your order object in model (rather than individual fields) and access it's fields/methods in view (Thymeleaf)?

In controller
