QBit development microservice

QBit development microservice
I. QBit database Introduction

QBit is an open-source responsive development library used to build microservices and supports JSON, HTTP, WebSocket, and REST. QBit uses responsive programming to establish elastic REST, cloud-based WebSocket, and Web services. QBit is an SOA evolution for mobile and cloud computing. QBit is a small, lightweight microservice development library that provides support for service discovery, service health, responsive state services, type events, and reactive programming commonly used in Java.
QBit is very small and extremely fast.

Ii. Gradle Build File

group 'qbit-ex'version '1.0-SNAPSHOT'apply plugin: 'java'apply plugin: 'application'mainClassName = "com.mammatustech.HelloWorldService"compileJava {    sourceCompatibility = 1.8}repositories {    mavenCentral()    mavenLocal()}dependencies {    testCompile group: 'junit', name: 'junit', version: '4.11'    compile group: 'io.advantageous.qbit', name: 'qbit-admin',                                                  version: '0.9.0-M1'    compile group: 'io.advantageous.qbit', name: 'qbit-vertx',                                                  version: '0.9.0-M1'}

Currently, the latest version of QBit microservice library is 0.9.0.M2.

Iii. Use QBit to write sample code

package com.mammatustech;import io.advantageous.qbit.admin.ManagedServiceBuilder;import io.advantageous.qbit.annotation.RequestMapping;@RequestMapping("/hello")public class HelloWorldService {    @RequestMapping("/hello")    public String hello() {        return "hello " + System.currentTimeMillis();    }    public static void main(final String... args) {        final ManagedServiceBuilder managedServiceBuilder =                ManagedServiceBuilder.managedServiceBuilder()                                     .setRootURI("/root");        /* Start the service. */        managedServiceBuilder.addEndpointService(new HelloWorldService())                .getEndpointServerBuilder()                .build().startServer();    }}

4. Run the code

# gradle run

5. Use curl for testing

$ curl http://localhost:8080/root/hello/hello"hello 1440742489358"

6. Test with wrk

Wrk is an open-source HTTP Benchmark Testing Tool. When running on a single multi-core CPU, wrk can produce significant load. It combines multi-threaded design and scalable event notification systems (such as epoll and kqueue ).
Wrk also provides an optional LuaJIT script for executing HTTP request generation, Response Processing, and custom reports.
