在Spring中将路径变量绑定到自定义模型对象 [英] Bind Path variables to a custom model object in spring

问题描述

我有一个模拟我的请求的课程，例如

I have a class that models my request, something like

class Venue {
    private String city;
    private string place;

    // Respective getters and setters.
}

我想支持一个RESTful URL来获取有关场地的信息。所以我有这样的控制器方法。

And I want to support a RESTful URL to get information about a venue. So I have controller method like this.

@RequestMapping(value = "/venue/{city}/{place}", method = "GET")
public String getVenueDetails(@PathVariable("city") String city, @PathVariable("place") String place, Model model) {
    // code
}

有没有办法，我可以说在春天将我的路径变量绑定到模型对象（在这个案例Venue）而不是获取每个单独的参数？

Is there a way, I can say in spring to bind my path variables to the model object (in this case Venue) instead of getting every individual parameter?

推荐答案

Spring MVC 提供将请求参数和路径变量绑定到JavaBean的功能，在您的情况下是 Venue 。
例如：

Spring MVC offers the ability to bind request params and path variables into a JavaBean, which in your case is Venue. For example:

@RequestMapping(value = "/venue/{city}/{place}", method = "GET")
public String getVenueDetails(Venue venue, Model model) {
    // venue object will be automatically populated with city and place
}

请注意，您的JavaBean必须具有 city 和 place 它的工作属性。

Note that your JavaBean has to have city and place properties for it to work.
