Micronaut 声明式 HttpClient 超时

Question

我有这个声明式客户端：

@Retryable(attempts = "5", multiplier = "1.2")
@Client("\${client-url}")
@Headers(
    Header(name = USER_AGENT, value = "Micronaut Http Client"),
)
interface MyApiClient {

    @Get("/locations?location={location}")
    suspend fun validationLocation(@QueryValue location: String) : LocationResponse
}

我已将客户端超时设置为 30 秒：

micronaut:
 http:
    client:
      read-timeout: 30s

我随机得到：

Client <package> received HTTP error response: Read Timeout

造成这种非常烦人的行为的原因是什么？

Answer 1

这个问题似乎与同一个问题有关：Micronaut ReadTimeoutException

显然配置没有注入。您可能必须以编程方式设置它。

Answer 2

显然，从函数中删除 suspend 并使其返回 Single<LocationResponse> 会使超时消失。
