java.lang.IllegalArgumentException:未能解析占位符'BASE_URL‘

Question

尽管我已经将属性添加到application.properties文件中，但我还是得到了java.lang.IllegalArgumentException: Could not resolve the placeholder 'BASE_URL'。老实说，我要使用这个值的feignClient是从application.proprties中提取的，它会进一步解析local.env文件中的值。我还注意到，我的一些属性显示为未被IntelliJ使用，即使我已经使用了它们。附上我的代码用法、application.properties和local.env，以便更好地理解下面的内容

伪装客户端：

@FeignClient(value = "${service.name}", url = "${base.url}")
public interface BuddyClient {

    @PostMapping(
            value = "${primary.user.url}",
            produces = MediaType.APPLICATION_JSON_VALUE,
            consumes = MediaType.APPLICATION_JSON_VALUE
    )
    ResponseEntity<PrimaryUserCreationResponse> createAccount(
            @RequestHeader("Content-Type") String contentType,
            @RequestHeader("PartnerName") String partnerName,
            @RequestHeader("PartnerKey") String partnerKey,
            @Payload PrimayUserCreationRequest request
    ) throws TimeoutException;
}

application.properties

service.name=buddy //IntelliJ shows unused
base.url=${BASE_URL} //IntelliJ shows unused
primary.user.url=${PRIMARY_USER_URL} //IntelliJ shows used

local.env

BASE_URL=https://externalapi.in
PRIMARY_USER_URL=/api/User

完全错误

我猜对于local.env来说，BASE_URL属于内部脚本，BUDDY_BASE_URL应该在local.env和/或“url值上不应该有BASE_URL协议前缀”中。
