• Maven repository: https://bintray.com/opentoolset/maven-repo/netty-agents/

Features

• Support for bi-directional communication with continuous channels,
• Performance, customization and flexibility using nice features of Netty library (socket level communication, pipes and filters pattern, etc.)
• Ability to design and use of a strongly-typed (with POJO objects) and well-defined protocol in applications
• Support for blocking, request-response based communication model as well as supporting asynchronous pattern
• Easily implementation of communication and security requirements in any Java project by writing lower code using a simplified library interface based on agent concept.
• Secure communication with TLS and mutual certificate authentication

Simple Use Case

Sample server code like below:

// ...

ServerAgent serverAgent = new ServerAgent();
serverAgent.setMessageHandler(SampleMessage.class, message -> handleMessage(message));
serverAgent.setRequestHandler(SampleRequest.class, request -> handleRequest(request));
serverAgent.startup();

private static void handleMessage(SampleMessage message) {
    // ...
    // business logic
    // ...
}

private static SampleResponse handleRequest(SampleRequest request) {
    SampleResponse response = new SampleResponse();
    // ...
    // business logic
    // ...
    return response;
}

Sample client code like below:

ClientAgent clientAgent = new ClientAgent();
serverAgent.startup();
clientAgent.sendMessage(new SampleMessage()); // Sends a message to server without waiting a response
SampleResponse response = clientAgent.doRequest(new SampleRequest()); // Sends a request to server by waiting until receiving a response or timeout
