Java Chassis | English Build Status Coverage Status Maven Central License Gitter

Apache ServiceComb Java Chassis 给开发者提供一个快速构建微服务的JAVA SDK。它包含如下特性:

  • 多种开发风格,REST(JAX-RS、Spring MVC)和RPC
  • 多种通信协议, HTTP over Vert.x、Http Over Servlet、Highway等
  • 统一一致的服务提供者、服务消费者处理链,以及基于契约的开箱即用的服务治理能力

开发者可以通过设计选型参考了解更多特性和设计原理。

为什么使用Java Chassis

  • 高性能

    Java Chassis 网络层基于 Vert.x 实现, 支持开发者使用响应式编程, 开发者在使用熟悉的REST风格设计业务接口的时候,也能够获取到非常高性能的吞吐量。同时还提供了Highway协议,满足更高性能场景的要求。

  • 原生支持OpenAPI

    Java Chassis 的接口开发、服务治理都基于 Swagger ,并通过接口语义检查,使得接口定义符合 OpenAPI 规范.

  • 灵活的开发方式

    开发者可以使用 SpringMVC/JAX-RS/transparent RPC 任意一种方式定义服务端接口, 并使用RPC/RestTemplate 等方式访问这些接口. 得益于Java Chassis的通信层与开发方式分离的设计,开发者可以在 Rest over Vertx/Rest over Servlet/Highway等通信模式下自由切换.

  • 开箱即用的服务治理能力

    Java Chassis 提供了大量开箱即用的服务治理能力,包括服务发现、熔断容错、负载均衡、流量控制等。

快速开始

定义提供者:

import org.apache.servicecomb.*;
@RpcSchema(schemaId = "helloworld")
public class HelloWorldProvider implements HelloWorld {
    public String sayHello(String name) {
        return "Hello " + name;
    }
}

定义消费者:

import org.apache.servicecomb.*;
@Component
public class HelloWorldConsumer  {
	@RpcReference(microserviceName = "pojo", schemaId = "helloworld")
	private static HelloWorld helloWorld;

	public static void main(String[] args) {
		helloWorld.sayHello("Tank");
	}
}

用户文档

请访问 ServiceComb Java Chassis 开发指南.

编译Java Chassis

开发者可以通过公有mavan仓库使用Java Chassis。 如果需要构建项目,需要使用JDK 8版本,并预先安装maven。

  mvn clean install

运行测试用例

开发者需要预先安装docker。

  mvn clean install -Pdocker -Pit  -Pdemo-run-release

使用docker machine。

  mvn clean install -Pdocker -Pit -Pdocker-machine -Pdemo-run-release
