Pull request overview
This PR adds support for customizing the HttpClientConnectionManager in HttpClient5FeignConfiguration through a new HttpClientConnectionManagerBuilderCustomizer interface, mirroring the existing customization pattern for CloseableHttpClient. This addresses the need to configure connection manager settings like TLS handshake timeouts without overriding the entire bean configuration.
Key Changes:
- Introduced
HttpClientConnectionManagerBuilderCustomizerinterface for programmatic connection manager configuration - Updated
hc5ConnectionManagerbean to accept and apply customizers - Added documentation and test coverage for the new customization mechanism

The underlying http client (in my case the apache hc5) is already well-customizable via properties and also via supplying my own beans. I'd like a further middle ground by allowing a list of customzer for
HttpClientConnectionManagerinHttpClient5FeignConfiguration, as it also exists for theCloseableHttpClientin the same file.In my case, I need to configure the
TlsConfig::handshakeTimeoutas a result of the new handling in 5.5.1 (see https://issues.apache.org/jira/browse/HTTPCLIENT-2386)Describe the solution you'd like
Allow a list of
ObjectProvider<List<HttpClientConnectionManagerBuilderCustomizer>> customizerProviderto thehc5ConnectionManagerbean method.Describe alternatives you've considered
Yes, I know I can override the full
HttpClientConnectionManageras my own bean, but then I loose the rest of the auto-configuration logic for this bean. I can also not just copy the bean metho and add my own logic, as I would also have to copy private methods likehttpsSSLConnectionSocketFactoryand my implementation would, over time, surely diverge for the curated defaults that I would like to keep and profit from.Additional context
I am happy to create a PR, unless there is a good reason why this feature does and should not exist.
