Which Java REST Client is Right for Your Project?

Creating RESTful Clients in Java: Exploring Options

Introduction:

RESTful APIs are gaining prominence in modern distributed computing. However, creating Java REST clients that interact seamlessly with these APIs can be a challenge. This article explores various techniques and frameworks available to address this need.

HTTPConnection vs. Specialized Clients:

One approach is to utilize HTTPConnection and perform manual parsing of results. However, this method can be tedious and prone to errors. Specialized clients, such as Jersey or Apache CXR, provide a more convenient and robust solution.

Apache CXF:

Apache CXF offers multiple REST client options:

• Invocation API for direct method invocation on REST services.
• Client proxy using Spring or JAX-RS annotations for automated method mapping.
• REST-aware Apache HTTP Client for building custom clients.

Jersey:

Jersey provides clients based on JAX-RS annotations. It simplifies resource discovery and automatic marshalling of XML and JSON content.

Spring RestTemplate and WebClient:

Spring RestTemplate and its successor, Spring WebClient, are lightweight and offer customizable configuration. They support multiple representations (e.g., JSON, XML) and integration with other Spring components.

Other Options:

In addition to the above, consider these options:

• Apache HTTP Components Fluent Adapter: A replacement for the legacy Commons HTTP Client, with improved Fluent API and JSON parsing support.
• OkHttp: A lightweight client with support for newer HTTP protocols (e.g., HTTP/2).
• Ning Async-http-client: A NIO-based client for asynchronous REST operations.
• Feign and Retrofit: Clients that automate remote REST access using Java interfaces.

Выбор клиента HTTP/REST:

When selecting an HTTP/REST client, consider the following factors:

• Framework integration: Use the client that aligns with your existing framework (e.g.,Vert.x, Play).
• Threading: Ensure the client supports your preferred multi-threading approach.
• Performance and features: Choose a client that suits your application's specific needs and performance requirements.
