jrpcx

rpcx的原生java端

实现编码

  • msgpack (rpcx默认编码)
  • json

实现功能

  • 基本调用(TCP)
  • 服务注册发现(etcdv2)
  • 服务超时
  • 失败重试
  • 支持元数据(使用方法结果类继承MetaData)
  • 支持spring注解

使用方法

定义服务接口

/**
 * 测试接口
 *
 * @author heldiam
 */
public interface Arith {

    /**
     * 乘法
     *
     * @param request 请求参数
     * @return
     */
    ArithMulResponse Mul(ArithMulRequest request);

}

请求结构

/**
 *
 * @author heldiam
 */
public class ArithMulRequest {

    private Integer A;
    private Integer B;

    public Integer getA() {
        return A;
    }

    public void setA(Integer A) {
        this.A = A;
    }

    public Integer getB() {
        return B;
    }

    public void setB(Integer B) {
        this.B = B;
    }

}

返回结果结构

/**
 * 返回结果
 * @author heldiam
 */
public class ArithMulResponse implements Serializable{
    private Integer C;

    public Integer getC() {
        return C;
    }

    public void setC(Integer C) {
        this.C = C;
    }
    
}

服务端

服务路径只取类名不包含包路径

/**
 * @author kinwyb
 * @date 2019-06-15 09:07
 **/
public class ServerMain {

    public static void main(String[] args) throws Exception {
        BasicConfigurator.configure();
        Arith arith = request -> {
            ArithMulResponse response = new ArithMulResponse();
            response.setC(request.getA() * request.getB());
            return response;
        };
        Service.registerService(arith, Arith.class);
        EtcdV2Discovery discovery = new EtcdV2Discovery("127.0.0.1:2379");
        discovery.setBasePath("/jrpcx");
        Server server = new Server("127.0.0.1:8972", discovery);
        new Thread(() -> server.Start()).run();
        System.out.println("定时关闭服务");
        Thread.sleep(30000);
        server.Close();
    }
}

客户端

⚠️ 注意：执行是异步的,直接读取结果属性可能为空。必须通过get方法来获取结果.通过get方法获取该方法会一直阻塞到服务端返回结果

/**
 * @author kinwyb
 * @date 2019-06-14 17:38
 **/
public class ClientMain {

    public static void main(String[] args) throws Exception {
        BasicConfigurator.configure();
        EtcdV2Discovery discovery = new EtcdV2Discovery("127.0.0.1:2379");
        discovery.setBasePath("/jrpcx");
        Client client = Selector.WeightedRountRobin(discovery).buildClient();
        Arith arith = client.Proxy(Arith.class);
        ArithMulRequest req = new ArithMulRequest();
        req.setA(7);
        req.setB(8);
        for (int i = 0; i < 1000; i++) {
            ArithMulResponse rep = arith.Mul(req);
            System.out.println("结果:" + rep.getC());
            Thread.sleep(1000);
        }
        client.Close();
    }

}

Spring注解支持

详情查看examples/spring

@ComponentScan(value = {"com.heldiam"})
@RpcxDiscovery //开启注册中心(必须)
@RpcxServer //开启服务
//@RpcxClient //开启客户端
public class Main {

    public static void main(String[] args) {
        BasicConfigurator.configure();
        AnnotationConfigApplicationContext annotationConfigApplicationContext = new AnnotationConfigApplicationContext();
        annotationConfigApplicationContext.register(Main.class);
        annotationConfigApplicationContext.refresh();
        SimpleComponent component = annotationConfigApplicationContext.getBean(SimpleComponent.class);
        System.out.println(component.getData());
        annotationConfigApplicationContext.close();
    }

}
