Spring Cloud整合Thrift RPC(一) - spring-cloud-thrift-

前言

前面几篇文章有对 ApacheThrift的使用和原理做了介绍。在微服架构流行的今天,自然而然就会想到 SpringBoot和 SpringCloud作为微服务的基础框架。然而, SpringCloud从诞生以来,就基于 HTTP协议的轻量级 RestfulAPI作为服务之间的通信方式。

在微服务架构设计中,可以分为外部服务和内部服务。两者主要区别是:

  • 外部服务:基于 Restful风格的 HTTP协议,通过外网向外部提供服务,相对来说简单并且通用。

  • 内部服务:基于 RPC消息通信的 TCP/IP协议,提供内网服务与服务之间的调用,以达到减少带宽、降低延迟率、提高性能。

一些应用场景,尤其是内部服务需要高频地调用,就需要考虑是否需要改造为 RPC实现,来提高吞吐量和系统性能,比如说鉴权服务一类。

Spring Cloud整合Thrift RPC(一) - spring-cloud-thrift-
spring-cloud-starter-thrift 提供 SpringCloud 对可伸缩的跨语言服务调用框架 ApacheThrift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。而 spring-cloud-starter-thrift-examples 子模块提供了 3个示例项目: calculator、 deposit和 test。

  • calculator:简单上手项目示例。

  • deposit:复杂业务场景项目示例。

  • test:性能测试项目示例。

服务端

  1. 支持 ApacheThrift的各种原生线程服务模型,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)和线程选择器模型( threadedSelector)。

  2. 支持 ApacheThrift0.10.0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。

  3. 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。

  4. 支持 ServerGroup形式的启动方式,每个服务实例可以开启多台 ThriftServer,通过不同的端口号暴露给客户端。

客户端

  1. 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。

  2. 支持 ApacheThrift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。

  3. 支持与 SpringCloudConsul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。

  4. 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。

项目结构:

Spring Cloud整合Thrift RPC(一) - spring-cloud-thrift-

  • calculator

  • calculator-client

  • calculator-iface

  • calculator-server

spring-cloud-starter-thrift 使用的是 0.10.0版本的 thrift。以 calculator项目入手,首先,通过 ThriftIDL (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。

首先进入 spring-cloud-starter-thrift 根目录, pom.xml 定义如下:

pom.xml

<parent>

    <groupId>org.springframework.boot</groupId>

    <artifactId>spring-boot-starter-parent</artifactId>

<version>1.0-SNAPSHOT</version>

<modules>

    <module>calculator-client</module>

    <module>calculator-server</module>

    <module>calculator-iface</module>

</modules>

    <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>

    <java.version>1.8</java.version>

    <spring-cloud.version>Dalston.SR4</spring-cloud.version>

</properties>

<build>

    <plugins>

        <plugin>

            <artifactId>maven-compiler-plugin</artifactId>

            <configuration>

                <source>1.8</source>

                <target>1.8</target>

                <encoding>UTF-8</encoding>

            </configuration>

        </plugin>

        <plugin>

            <groupId>org.apache.maven.plugins</groupId>

            <artifactId>maven-jar-plugin</artifactId>

            <version>2.6</version>

        </plugin>

    </plugins>

</build>

将项目打包并安装到本地 Maven仓库:

mvn clean install

Thrift IDL编写

namespace java com.icekredit.rpc.thrift.example

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 ThriftIDL编译生成器,下载地址:http://thrift.apache.org/docs/install。通过编译器生成 .java的 Stub类文件。

thrift -gen java ./CalculatorService.thrift

编译器生成的 CalculatorService.java文件。 CalculatorService.java有成千上万行代码。对于开发人员而言,只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 HelloWorldService.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 HelloWorldService.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 HelloWorldService.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 HelloWorldService.AsyncClient 的实例对象,以异步的方式访问服务端提供的服务方法。

中间契约(calculator-iface)

在中间契约模块引入 thrift的 maven依赖,拷贝上一步 thrift编译生成器生成的 CalculatorService源文件到此模块。

pom.xml

<parent>

    <artifactId>calculator</artifactId>

    <groupId>com.icekredit.rpc.thrift.examples</groupId>

        <artifactId>libthrift</artifactId>

        <version>0.10.0</version>

    </dependency>

</dependencies>

服务端(calculator-server)

在服务端模块引入:

  • spring-cloud-starter-thrift-server: thrift服务端的 starter程序。

  • calculator-iface:中间契约模块,这里作为服务端骨架( Skeleton)程序。

pom.xml

            <artifactId>spring-boot-maven-plugin</artifactId>

        </plugin>

    </plugins>

</build>

在 application.yml中配置 thrift服务端的运行参数:

application.yml

## 服务端Restful服务所在的HTTP端口号

server:

  port: 8080

## 用于Consul健康检查

endpoints:

  actuator:

    sensitive: false

    enabled: true

management:

  security:

    enabled: false

## Spring Thrift服务端配置

spring:

  thrift:

    server:

      service-id: thrift-rpc-calculator ##

      service-model: hsHa  ## 半同步/半异步服务模型

      port: 25000  ## 服务端RPC服务所在的TCP端口号

      worker-queue-capacity: 1000

      ## 半同步/半异步服务模型参数配置

      hs-ha:

        min-worker-threads: 5  ## 最少工作线程数

        max-worker-threads: 20  ## 最大工作线程数

        keep-alived-time: 3  ## 空闲线程存活时间

实现 ThriftIDL生成的骨架( Skeleton)类 CalculatorService的内部接口 Iface,编写具体的业务逻辑:

这里需要注意几点:

  • 实现 CalculatorService.Iface接口。

  • 实现类标记 @ThriftService注解,包含以下属性:

  • name:通过 name标识服务名称,缺省时默认为类名称首字母小写。

  • version:通过 version标识服务版本,缺省值为 1.0,也就是说同一个服务名称可以拥有多个版本实现。

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();

    }

}

对服务端程序进行打包:

mvn clean package -Dmaven.test.skip=true

编写 Dockerfile 文件:

FROM openjdk:8-jdk-alpine

ADD target/spring-boot-thrift-server-0.0.1-SNAPSHOT.jar 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 ThriftServer 的服务镜像:

docker build . -t icekredit/calculator-server

客户端(calculator-client)

在客户端模块引入:

  • spring-cloud-starter-thrift-client: thrift客户端的 starter程序。

  • calculator-iface:中间契约模块,这里作为客户端桩( Stub)程序。

pom.xml

        </plugin>

    </plugins>

</build>

在 application.yml中配置 thrift客户端的运行参数,需要与服务端配置保持一致:

## 客户端Restful服务所在的HTTP端口号

server:

  port: 8080

## 用于Consul健康检查

endpoints:

  actuator:

    sensitive: false

    enabled: true

management:

  security:

    enabled: false

## Spring Thrift客户端配置(Thrift Client的自动配置取决于Spring Cloud Consul的正确配置)

spring:

  application:

    name: thrift-calculator-client

  cloud:

    consul:

      host: 192.168.91.128  ## Consul的IP地址

      port: 8500  ## Consul的HTTP端口号

      discovery:

        register: false  ## 不使用SpringCloud提供的基于服务的程序注册方式

        register-health-check: false  ## 不使用Spring Cloud进行健康检查

      retry:

        max-attempts: 3

        max-interval: 2000

  ## Thrift Client配置

  thrift:

    client:

      package-to-scan: com.icekredit.rpc.thrift.example.rpc  ## 标记由有注解@ThriftClient接口的包路径

      service-model: hsHa  ##服务线程模型(这里必须与服务端保持一致, 默认都是hsHa)

      ## 客户端连接池配置

      pool:

        retry-times: 3  ## 异常失败,连接超时后的重试次数

        ## key由IP + Port组成,唯一标识一个服务实例

        pool-max-total-per-key: 200 ## 客户端保持的最大连接数,包含不同的服务和服务实例

        pool-min-idle-per-key: 10  ## 每个服务实例最小的空闲连接数

        pool-max-idle-per-key: 40  ## 每个服务实例最大的空闲连接数

        pool-max-wait: 30000  ## 空闲连接最大存活时间

        connect-timeout: 2000  ## 连接超时时间

编写 ThriftClient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 ThriftIDL 生成的 Stub 类 CalculatorService 中的 Client内部类。

  • 接口需要标识 @ThriftClient 注解, @ThriftClient 包含如下属性:

  • 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)。

  • refer:客户端桩 Stub的类型,例如这里是 CalculatorService.class。

  • version: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。

CalculatorThriftClient.java

@ThriftClient(serviceId = "thrift-rpc-calculator", refer = CalculatorService.class, version = 2.0)

public interface CalculatorThriftClient extends ThriftClientAware<CalculatorService.Client> {

}

使用注解 @ThriftReferer,在客户端的 Controller 中注入 CalculatorThriftClient。 使用时,通过 CalculatorThriftClient.thriftClient() 方法,即可调用 ThriftServer的服务方法。

RpcCalculatorController.java

@RestController

@RequestMapping("/rpc")

public class RpcCalculatorController {

    @ThriftReferer

    private CalculatorThriftClient calculators;

    @GetMapping("/add")

    public int add(@RequestParam("arg1") int arg1, @RequestParam("arg2") int arg2) throws Exception {

        return calculators.client().add(arg1, arg2);

    }

    @GetMapping("/subtract")

    public int subtract(@RequestParam("arg1") int arg1, @RequestParam("arg2") int arg2) throws Exception {

        return calculators.client().subtract(arg1, arg2);

    }

    @GetMapping("/multiply")

    public int multiply(@RequestParam("arg1") int arg1, @RequestParam("arg2") int arg2) throws Exception {

        return calculators.client().multiply(arg1, arg2);

    }

    @GetMapping("/division")

    public int division(@RequestParam("arg1") int arg1, @RequestParam("arg2") int arg2) throws Exception {

        return calculators.client().division(arg1, arg2);

    }

}

测试方便,在本地开发环境配置 Consul的地址,运行客户端程序即可。对于容器环境测试,配置对客户端程序进行打包:

mvn clean package -Dmaven.test.skip=true

编写 Dockerfile 文件:

FROM openjdk:8-jdk-alpine

ADD target/spring-boot-thrift-client-0.0.1-SNAPSHOT.jar calculator-client.jar

ENTRYPOINT ["java", "-jar", "calculator-client.jar"]

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

docker build . -t icekredit/calculator-client

简单测试

发布服务端程序

为了方便测试,在一台主机上启动三个 ThriftServer 的 docker 容器,以不同的端口区分,分别指定对应的端口号和 Consul 注册信息:

ThriftServer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" \

      icekredit/calculator-server

ThriftServer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" \

      icekredit/calculator-server

ThriftServer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" \

        icekredit/calculator-server

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 ThriftServer 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

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

Spring Cloud整合Thrift RPC(一) - spring-cloud-thrift-

有关 Consul和 Registrator的安装配置以及使用,请参考:Docker+Consul+Registrator(一) 搭建服务发现与注册集群!

服务端程序成功运行, ThriftRPC服务正常发布!
启动客户端程序

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节点信息,缓存到本地服务列表中。
