Digipost HTTP Client Builder

A tiny library for building instances of Apache HttpClient configured with sensible defaults.

Usage

Here are some common use cases to quickly get you started.

Client with sensible defaults:

CloseableHttpClient client = HttpClientFactory.createDefault();

Custom ssl context

PoolingHttpClientConnectionManager connectionManager = HttpClientConnectionManagerFactory
        .createDefaultBuilder()
        .setSSLSocketFactory(
                SSLConnectionSocketFactoryBuilder.create()
                        .setSslContext(getSslContext())
                        .setTlsVersions(TLS.V_1_3)
                        .build()
        )
        .build();

CloseableHttpClient client = HttpClientFactory.create(connectionManager);

Disable connection monitor

The connection monitor evicts idle and expired connections. It is by default started when the client is built.

It can be disabled by the following code:

CloseableHttpClient client = HttpClientFactory.create(HttpClientSettings.DEFAULT.connectionEvictionPolicy(ConnectionEvictionPolicy.NONE));

PS: If connection monitor is not disabled, and a new connection manager is set after the client builder has been created (i.e clientBuilder.setConnectionManager(other)), the 'old' connection monitor will still run and monitor the old connection manager.
