Java:Feign客户端中的默认值 [英] Java: default value in Feign client

问题描述

告诉我，如何在Feign客户端或其他客户端的参数中设置默认值?

Tell me, how can I set the default value in a parameter in the Feign client or other?

这是我的代码.我指定了默认值，但它不起作用:(

Here is my code. I indicated the default value, but it does not work :(

服务:

public Price get(PricesRequest request) {
        return  priceFeignClient.get(
                       request.getPrice(),
                       request.getAddress(),
                       request.getCode(),
                       request.getCurrency()
                )
}

假客户:

public interface PriceFeignClient {
    @GetMapping
    Price get(@RequestParam("price") String price,
              @RequestParam("address") String Address,
              @RequestParam(value = "code", required = true, defaultValue = "AAA") String code,
              @RequestParam("currency") String currency
    );

我想为代码" 参数设置默认值.

I want to make a default value for the "code" parameter.

推荐答案

问题解决如下:

将此添加到我敲过的服务器上的主api中(即，在接收方，而不是在发送方请求上).

added this to the main api on the server that I was knocking on (i.e., on the receiving side, and not on the sending side request).

@RequestParam(value = "code", required = false, defaultValue = "AAA") String code

必填项是 required = false (而不是 required = true ).
