Usage strategy of minimizing middleware in java framework

In order to minimize the use of middleware in Java frameworks, you can choose lightweight message queues (such as Kafka), use asynchronous communication, directly call remote services, reduce middleware dependencies, and explore no middleware when possible solution.

Usage strategy of minimizing middleware in Java framework

Introduction

In Java applications, middleware is a key component that provides cross-system communication and coordination capabilities. However, excessive use of middleware can introduce complexity and performance overhead. This article will describe how to minimize the use of middleware in Java frameworks to simplify design and improve performance.

Strategy

• Use lightweight message queues: Consider using lightweight message queues such as Kafka, ActiveMQ, etc., which have Low overhead and high scalability.
• Choose asynchronous communication: Use asynchronous communication mechanisms, such as message queues or reactive programming, to reduce synchronous waits for interacting with middleware.
• Directly calling remote services: For simple communication between components, directly calling remote services is more lightweight and efficient than using middleware.
• Minimize middleware dependencies: Choose middleware carefully and only use its essential features. Avoid creating unnecessary abstractions or couplings.
• Explore middleware-free solutions: Consider exploring middleware-less solutions, such as using gRPC or RESTful APIs to communicate directly between services.

Practical case

Using Kafka for asynchronous messaging

// KafkaProducer 示例
    val properties = Properties()
    properties["bootstrap.servers"] = "localhost:9092"

    val producer = KafkaProducer<String, String>(properties)

    val future = producer.send(ProducerRecord("my-topic", "some-data"))
    future.get() // (可选) 等待消息发送完成

// KafkaConsumer 示例
    val properties = Properties()
    properties["bootstrap.servers"] = "localhost:9092"
    properties["group.id"] = "my-group"

    val consumer = KafkaConsumer<String, String>(properties)
    consumer.subscribe(Arrays.asList("my-topic"))

    while (true) {
        val records = consumer.poll(100)
        records.forEach { record ->
            println("${record.key()}: ${record.value()}")
        }
    }

Direct remote service call ( Using gRPC)

// GreeterServiceGrpc 客户端
    val channel = ManagedChannelBuilder.forAddress("localhost", 9090).usePlaintext().build()
    val client = GreeterServiceGrpc.newBlockingStub(channel)

    val request = HelloRequest.newBuilder().setName("John Doe").build()
    val response = client.sayHello(request)

    println("Received response: ${response.message}")

Conclusion

By adopting these strategies and practices, you can effectively minimize the use of middleware in Java frameworks, thereby improving performance, Simplify design and reduce complexity. In some cases, exploring middleware-free solutions can further optimize communications.
