Riptide: HTTP Client

Feather

Javadoc Maven Central

Riptide: HTTP Client offers an alternative integration of Spring's RestTemplate (or ClientHttpRequestFactory) and Apache's HTTP Client.

Example

final Http http = Http.builder()
        .requestFactory(new ApacheClientHttpRequestFactory(client))
        .build();

Features

  • independent from Riptide: Core, i.e. it can be used with a plain RestTemplate
  • fixes several issues with Spring's HttpComponentsClientHttpRequestFactory:
    • preserve the underlying client's request config
    • releasing connections back to the pool after closing streams
    • aborts connection when the stream hasn't been consumed fully

Dependencies

  • Java 17

Installation

Add the following dependency to your project:

<dependency>
    <groupId>org.zalando</groupId>
    <artifactId>riptide-httpclient</artifactId>
    <version>${riptide.version}</version>
</dependency>

Configuration

The majority of configuration is done on the underlying HttpClient:

CloseableHttpClient client = HttpClientBuilder.create()
        // TODO configure client here
        .build();

final Http http = Http.builder()
        .requestFactory(new ApacheClientHttpRequestFactory(client))
        .build();

What the ApacheClientHttpRequestFactory in addition offers two modes of operation:

new ApacheClientHttpRequestFactory(client, Mode.BUFFERING)
Streaming (default)
Streams request bodies directly to the server. This requires less memory but any serialization error would result in an invalid, partial request to the server.
Buffering
Buffers request bodies before sending anything to the server. This requires more memory but allows to catch serialization early without the server noticing.
