Spring Cloud整合Thrift RPC(一) - 使用指南

2019年6月13日 302次阅读来源: 零壹技术栈

前言

前面几篇博客，着重对Apache Thrift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Spring Boot和Spring Cloud作为微服务的基础框架。然而，Spring Cloud从诞生以来，就基于HTTP协议的轻量级Restful API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-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。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

支持 Apache Thrift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)。
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。

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 Thrift 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。

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>1.5.8.RELEASE</version>
    <relativePath/> <!-- lookup parent from repository -->

<version>1.0-SNAPSHOT</version>
<modules>
    <module>calculator-client</module>
    <module>calculator-server</module>
    <module>calculator-iface</module>
</modules>
<artifactId>calculator</artifactId>
<packaging>pom</packaging>

<properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <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 Thrift IDL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>
    <version>1.0-SNAPSHOT</version>
</parent>
<modelVersion>4.0.0</modelVersion>

        <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

<parent>
    <artifactId>calculator</artifactId>

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
</dependencies>

<build>
    <plugins>
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <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Thrift IDL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 Thrift Server 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 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Thrift Server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 Thrift Client 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 Thrift Server 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：

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" \
      icekredit/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" \
      icekredit/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" \
        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 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

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：

《Spring Cloud整合Thrift RPC(一) - 使用指南》 image

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，Thrift RPC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。
