spring-cloud-starter-thrift

简介

spring-cloud-starter-thrift提供Spring Cloud对可伸缩的跨语言服务调用框架Apache Thrift的封装和集成。

spring-cloud-starter-thrift包括客户端spring-cloud-starter-thrift-client和服务端spring-cloud-starter-thrift-server两个模块。

服务端：

支持Apache Thrift的各种原生服务线程模型，包括单线程阻塞模型(simple)、单线程非阻塞模型(nonBlocking)、线程池阻塞模型(threadPool)、半同步半异步模型(hsHa)和半同步半异步线程选择器模型(threadedSelector)。
支持Apache Thrift 0.10.0版本后提供的多路复用处理器，提供服务的统一注册管理功能。
支持由服务签名(服务ID + 客户端Stub接口名称 + 服务版本号)唯一标识服务Stub的具体实现类，支持服务版本的平滑升级。
支持Server Group形式的启动方式，每个服务实例可以开启多台Thrift Server，通过不同的端口号暴露给客户端。

客户端：

支持由服务签名(服务ID + 客户端Stub接口名称 + 服务版本号)唯一标识和调用服务端的Stub具体实现类。
支持Apache Thrift的Transport层的连接池管理，减少了客户端与服务端之间连接的频繁创建和销毁。
支持与Spring Cloud Consul的无缝集成，客户端通过心跳检测与服务注册中心Consul保持连接，动态定时的刷新服务列表、监测服务的启用、关闭和健康状态。
支持客户端负载均衡，包括随机、轮询的负载均衡策略，客户端的Thrift程序通过本地的服务缓存列表实现调用的动态转发。

快速开始

spring-cloud-starter-thrift使用的是0.10.0版本的thrift。

首先，通过Apache Thrift的IDL(接口描述语言)编写客户端桩Stub和服务端骨架Skeleton，通过.thrift文件定义接口规范。

calculator.thrift

namespace java io.ostenant.rpc.thrift.examples

service CalculatorService {
    i32 add(1: i32 arg1, 2: i32 arg2)
    i32 subtract(1: i32 arg1, 2: i32 arg2)
    i32 multiply(1: i32 arg1, 2: i32 arg2)
    i32 division(1: i32 arg1, 2: i32 arg2)
}

下载并安装0.10.0的Thrift IDL编译器，下载地址http://thrift.apache.org/docs/install。通过编译器生成.java接口的类文件。

thrift-0.10.0.exe -r -gen ./CalculatorService.thrift

编译器生成CalculatorService.java文件。CalculatorService.java有成千上万行代码。对于开发人员而言，使用原生的Thrift框架，仅仅需要关注以下四个核心接口/类：Iface, AsyncIface, Client和AsyncClient。

Iface：服务端通过实现CalculatorService.Iface接口，向客户端的提供具体的同步业务逻辑。
AsyncIface：服务端通过实现CalculatorService.Iface接口，向客户端的提供具体的异步业务逻辑。
Client：客户端通过CalculatorService.Client的实例对象，以同步的方式访问服务端提供的服务方法。
AsyncClient：客户端通过CalculatorService.AsyncClient的实例对象，以异步的方式访问服务端提供的服务方法。

CalculatorService.java

public class CalculatorService {

  public interface Iface {

    public int add(int arg1, int arg2) throws org.apache.thrift.TException;

    public int subtract(int arg1, int arg2) throws org.apache.thrift.TException;

    public int multiply(int arg1, int arg2) throws org.apache.thrift.TException;

    public int division(int arg1, int arg2) throws org.apache.thrift.TException;

  }

  public interface AsyncIface {

    public void add(int arg1, int arg2, org.apache.thrift.async.AsyncMethodCallback<Integer> resultHandler) throws org.apache.thrift.TException;

    public void subtract(int arg1, int arg2, org.apache.thrift.async.AsyncMethodCallback<Integer> resultHandler) throws org.apache.thrift.TException;

    public void multiply(int arg1, int arg2, org.apache.thrift.async.AsyncMethodCallback<Integer> resultHandler) throws org.apache.thrift.TException;

    public void division(int arg1, int arg2, org.apache.thrift.async.AsyncMethodCallback<Integer> resultHandler) throws org.apache.thrift.TException;

  }

  public static class Client extends org.apache.thrift.TServiceClient implements Iface {
    public static class Factory implements org.apache.thrift.TServiceClientFactory<Client> {
      public Factory() {}
      public Client getClient(org.apache.thrift.protocol.TProtocol prot) {
        return new Client(prot);
      }
      public Client getClient(org.apache.thrift.protocol.TProtocol iprot, org.apache.thrift.protocol.TProtocol oprot) {
        return new Client(iprot, oprot);
      }
    }

    public Client(org.apache.thrift.protocol.TProtocol prot)
    {
      super(prot, prot);
    }

    public Client(org.apache.thrift.protocol.TProtocol iprot, org.apache.thrift.protocol.TProtocol oprot) {
      super(iprot, oprot);
    }

  }
  public static class AsyncClient extends org.apache.thrift.async.TAsyncClient implements AsyncIface {
    public static class Factory implements org.apache.thrift.async.TAsyncClientFactory<AsyncClient> {
      private org.apache.thrift.async.TAsyncClientManager clientManager;
      private org.apache.thrift.protocol.TProtocolFactory protocolFactory;
      public Factory(org.apache.thrift.async.TAsyncClientManager clientManager, org.apache.thrift.protocol.TProtocolFactory protocolFactory) {
        this.clientManager = clientManager;
        this.protocolFactory = protocolFactory;
      }
      public AsyncClient getAsyncClient(org.apache.thrift.transport.TNonblockingTransport transport) {
        return new AsyncClient(protocolFactory, clientManager, transport);
      }
    }

    public AsyncClient(org.apache.thrift.protocol.TProtocolFactory protocolFactory, org.apache.thrift.async.TAsyncClientManager clientManager, org.apache.thrift.transport.TNonblockingTransport transport) {
      super(protocolFactory, clientManager, transport);
    }

  }
}

Application.java

@SpringBootApplication
public class Application {

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }

}

实现Thrift IDL生成的Stub类CalculatorService中的Iface接口，编写具体的业务逻辑：

RpcCalculatorService.java

@ThriftService(name = "rpcCalculatorService", version = 2.0)
public class RpcCalculatorService implements CalculatorService.Iface {

    @Override
    public int add(int arg1, int arg2) {
        BigDecimal arg1Decimal = new BigDecimal(arg1);
        BigDecimal arg2Decimal = new BigDecimal(arg2);
        return arg1Decimal.add(arg2Decimal).intValue();
    }

    @Override
    public int subtract(int arg1, int arg2) {
        BigDecimal arg1Decimal = new BigDecimal(arg1);
        BigDecimal arg2Decimal = new BigDecimal(arg2);
        return arg1Decimal.subtract(arg2Decimal).intValue();
    }

    @Override
    public int multiply(int arg1, int arg2) {
        BigDecimal arg1Decimal = new BigDecimal(arg1);
        BigDecimal arg2Decimal = new BigDecimal(arg2);
        return arg1Decimal.multiply(arg2Decimal).intValue();
    }

    @Override
    public int division(int arg1, int arg2) {
        BigDecimal arg1Decimal = new BigDecimal(arg1);
        BigDecimal arg2Decimal = new BigDecimal(arg2);
        return arg1Decimal.divide(arg2Decimal).intValue();
    }
}

编写Dockerfile文件：

FROM openjdk:8-jdk-alpine
ADD target/spring-boot-thrift-server-1.0.0jar calculator-server.jar
ENTRYPOINT ["java", "-jar", "calculator-server.jar"]

将Dockerfile和target/spring-boot-thrift-server-0.0.1-SNAPSHOT.jar拷贝到服务器上，构建Thrift Server的服务镜像：

docker build . -t ostenant/calculator-server

启动三个Thrift Server的docker容器，分别指定对应的端口号和Consul注册信息：

Thrift Server实例1(25001端口)：

docker run -d -p 8081:8080 -p 25001:25000 --name calculator-server-01 \
    -e "SERVICE_25000_NAME=thrift-rpc-calculator" \
	-e "SERVICE_25000_CHECK_TCP=/" \
	-e "SERVICE_25000_CHECK_INTERVAL=30s" \
	-e "SERVICE_25000_CHECK_TIMEOUT=3s" \
	-e "SERVICE_25000_TAGS=thrift-rpc-calculator-25001" \
	 ostenant/calculator-server

Thrift Server实例2(25002端口)：

docker run -d -p 8081:8080 -p 25002:25000 --name calculator-server-01 \
    -e "SERVICE_25000_NAME=thrift-rpc-calculator" \
	-e "SERVICE_25000_CHECK_TCP=/" \
	-e "SERVICE_25000_CHECK_INTERVAL=30s" \
	-e "SERVICE_25000_CHECK_TIMEOUT=3s" \
	-e "SERVICE_25000_TAGS=thrift-rpc-calculator-25002" \
	 ostenant/calculator-server

Thrift Server实例3(25003端口)：

docker run -d -p 8081:8080 -p 25003:25000 --name calculator-server-01 \
    -e "SERVICE_25000_NAME=thrift-rpc-calculator" \
	-e "SERVICE_25000_CHECK_TCP=/" \
	-e "SERVICE_25000_CHECK_INTERVAL=30s" \
	-e "SERVICE_25000_CHECK_TIMEOUT=3s" \
	-e "SERVICE_25000_TAGS=thrift-rpc-calculator-25003" \
	 ostenant/calculator-server

启动Consul和Registrator容器，Thrift Server的三个服务实例成功注册到Consul服务列表：

这里有关Consul和Registrator的安装配置以及使用，请参考官方文档，这里就不加以累述了！

观察各个容器的启动日志，如果包含以下几行输出信息，则表明Thrift Server成功启动并正常提供RPC服务。

2017-11-19 22:28:47.779  INFO 12960 --- [           main] c.i.r.t.s.context.ThriftServerContext    : Build thrift server from HsHaServerContext

至此，Thrift服务端程序正常运行，可供客户端Thrift程序调用！

}

编写Thrift Client的客户端代理接口，这里有两点注意事项：

接口需要继承于父接口ThriftClientAware，且ThriftClientAware里的泛型参数填写为Thrift IDL生成的Stub类CalculatorService中的Client内部类。

接口中有一个抽象方法T thriftClient()可以获取具体的Thrift Client的代理对象。

接口标识注解@ThriftClient：

(a). serviceId：此客户端代理接口绑定的Thrift服务端的服务注册ID(与服务端保持一致)。 (b). refer：Thrift服务端具体的Stub生成类。 (c). version: Stub生成类具体业务实现类的版本号(不填写默认为1.0)，需要与服务端保持一致。

@ThriftClient(serviceId = "thrift-rpc-calculator", refer = CalculatorService.class, version = 2.0)
public interface CalculatorThriftClient extends ThriftClientAware<CalculatorService.Client> {
}

在Controller中注入ThriftClientAware<? extend TServiceClient>子接口，使用注解@ThriftReferer标识即可成功注入。使用时，通过XxxxThriftClient.thriftClient()即可调用远程Thrift Server的服务方法。

RpcCalculatorController.java

@RestController
@RequestMapping("/rpc")
public class RpcCalculatorController {

    @ThriftReferer
    CalculatorThriftClient calculators;

    @GetMapping("/add")
    public int add(@RequestParam("arg1") int arg1, @RequestParam("arg2") int arg2) throws Exception {
        return calculators.thriftClient().add(arg1, arg2);
    }

    @GetMapping("/subtract")
    public int subtract(@RequestParam("arg1") int arg1, @RequestParam("arg2") int arg2) throws Exception {
        return calculators.thriftClient().subtract(arg1, arg2);

    }

    @GetMapping("/multiply")
    public int multiply(@RequestParam("arg1") int arg1, @RequestParam("arg2") int arg2) throws Exception {
        return calculators.thriftClient().multiply(arg1, arg2);
    }

    @GetMapping("/division")
    public int division(@RequestParam("arg1") int arg1, @RequestParam("arg2") int arg2) throws Exception {
        return calculators.thriftClient().division(arg1, arg2);
    }
}

在本地8080端口号启动Thrift客户端，正常启动后观察启动日志如下：

启动过程中，所有的标记有注解@ThriftClient的接口都生成了代理对象，并通过注解@ThriftReferer注入到Controller中。

同时，客户端启动时开启了一个ServerUpdater，定时动态的去Consul服务注册列表抓取健康的服务信息，缓存到本地服务列表中。
