为什么Micronaut会为客户端url配置丢弃主机名之后的所有内容

Question

在应用程序.yaml中配置Micronaut Http Clients时，我不知道url只能是主机名和端口，如果包含主机名和港口以外的任何内容，则Micronaut在选择要调用的主机时会丢弃它。Micronaut Configuring Http Clients文档没有明确警告读者这种行为。

这种行为是意料之中的吗？如果是，那么对于处理长URI的用户，有哪些选项，即：http://localhost:8080/application-name/v1.0/controller-name/endpoint

演示代码

BadClient.java

@Client("bad-client")
public interface BadClient {
@Get("/hello")
Maybe<String> getHello();
}

GoodClient.java

@Client("good-client")
public interface GoodClient {
@Get("/server2/hello")
Maybe<String> getHello();
}

application.yaml

micronaut:
application:
name: micronaut-client-issues
http:
services:
bad-client:
urls:
- http://localhost:8080/server2
good-client:
urls:
- http://localhost:8080
server:
port: 8080
cors:
enabled: true

当使用好的客户端时，它会按预期工作，但坏的客户端会抛出一个"404 Page Not Found"，其中包含以下日志详细信息：

URL应该只是没有路径的URL。如果你想提供一个上下文路径，你可以通过config:来实现

micronaut:
http:
services:
bad-client:
urls:
- http://localhost:8080
path: /server2
