JAVA RPC Thrift基操实现与微服务间调用-编程知识

一、Thrift 基操实现

1.1 thrift文件

namespace java com.zn.opit.thrift.helloworldservice HelloWorldService {string sayHello(1:string username)
}

1.2 执行命令生成Java文件

thrift -r --gen java helloworld.thrift

生成代码HelloWorldService接口如下

1.5 客户端

@Slf4j
public class ThriftClient {// 服务端IP地址public static final String SERVER_IP = "127.0.0.1";// 服务端端口号public static final int SERVER_PORT = 8010;public static void main(String[] args) throws Exception {log.info("客户端启动....");try (TTransport transport = new TSocket(SERVER_IP, SERVER_PORT)) {TProtocol protocol = new TBinaryProtocol(transport);HelloWorldService.Client client = new HelloWorldService.Client(protocol);transport.open();System.out.println("result = [remote: " + client.sayHello("wangxiaohu") + "]");} catch (Exception e) {log.error("客户端启动失败", e);}}
}

1.6 启动服务端、客户端进行测试

先启动服务端
在启动客户端

二、微服务间相互调用

2.1 通过thrift生成HelloWorldService

往前调转 1.2 执行命令生成Java文件

2.2 thrift客户端代理

/*** Thrift客户端代理*/
@SuppressWarnings({"unchecked" })
public class ThriftClientProxy {// 服务端端口号public static final int SERVER_PORT = 50000;public static <T> T getRemoteProxyObj(final Class<?> serviceInterface, String host) {return (T) Proxy.newProxyInstance(serviceInterface.getClassLoader(),new Class<?>[]{serviceInterface},(proxy, method, args) -> {TTransport transport = new TSocket(host, SERVER_PORT);TProtocol protocol = new TBinaryProtocol(transport);Class<?>[] argsClass = new Class[]{TProtocol.class};Constructor<?> cons = Class.forName(serviceInterface.getName().replace("Iface", "Client")).getConstructor(argsClass);T client = (T) cons.newInstance(protocol);transport.open();return method.invoke(client, args);});}
}

2.3 Thrift服务端代理

/*** Thrift服务端代理*/
public class ThriftServerProxy {private final Logger logger = LoggerFactory.getLogger(getClass());private static final int THRIFT_SERVER_PORT = 50000;// 端口private String serviceInterface;// 实现类接口private Object serviceImplObject;// 实现类@SuppressWarnings({ "unchecked", "rawtypes" })public void start() {new Thread(() -> {try {TServerSocket serverTransport = new TServerSocket(THRIFT_SERVER_PORT);// 实现类处理类classClass Processor = Class.forName(getServiceInterface() + "$Processor");// 接口Class Iface = Class.forName(getServiceInterface() + "$Iface");// 接口构造方法类Constructor con = Processor.getConstructor(Iface);// 实现类处理类TProcessor processor = (TProcessor) con.newInstance(serviceImplObject);TBinaryProtocol.Factory protocolFactory = new TBinaryProtocol.Factory(true, true);TThreadPoolServer.Args args = new TThreadPoolServer.Args(serverTransport);args.protocolFactory(protocolFactory);args.processor(processor);TServer server = new TThreadPoolServer(args);logger.info("Starting thrift server on port " + THRIFT_SERVER_PORT + " ..." + getServiceInterface());server.serve();} catch (Exception e) {e.printStackTrace();}}).start();}public ThriftServerProxy() {}public ThriftServerProxy(String serviceInterface, Object serviceImplObject) {this.serviceInterface = serviceInterface;this.serviceImplObject = serviceImplObject;}public String getServiceInterface() {return serviceInterface;}public void setServiceInterface(String serviceInterface) {this.serviceInterface = serviceInterface;}public Object getServiceImplObject() {return serviceImplObject;}public void setServiceImplObject(Object serviceImplObject) {this.serviceImplObject = serviceImplObject;}}

2.4 实现注解Rpc Service导入

@Slf4j
@Component
public class ThriftClientInterceptor implements BeanPostProcessor {@Resourceprivate DiscoveryClient discoveryClient;@Overridepublic Object postProcessAfterInitialization(Object bean, String beanName) throws BeansException {Class<?> beanClass = bean.getClass();Field[] fields = beanClass.getDeclaredFields();final Random random = new Random();for (Field field : fields) {ImpThrift impThrift = field.getAnnotation(ImpThrift.class);if (Objects.isNull(impThrift)) continue;try {String serviceId = impThrift.def();List<ServiceInstance> instances = discoveryClient.getInstances(serviceId);if (CollectionUtils.isEmpty(instances)) {// throw new ExtThriftException("instance [" + serviceId + "] not exists");log.warn("instance [{}] not exists", serviceId);}ServiceInstance serviceInstance = instances.get(random.nextInt(instances.size()));field.setAccessible(true);field.set(bean, ThriftClientProxy.getRemoteProxyObj(field.getType(), serviceInstance.getHost()));} catch (IllegalAccessException e) {e.printStackTrace();}}return BeanPostProcessor.super.postProcessAfterInitialization(bean, beanName);}
}

2.5 实现注解Rpc Service导出

@Component
public class ThriftServerInterceptor implements BeanPostProcessor {@Overridepublic Object postProcessAfterInitialization(Object bean, String beanName) throws BeansException {ExtThrift extThrift = bean.getClass().getAnnotation(ExtThrift.class);if (!Objects.isNull(extThrift)) {// String serviceName = extThrift.serviceName();Class<?>[] interfaces = bean.getClass().getInterfaces();ThriftServerProxy thriftServerProxy = new ThriftServerProxy(interfaces[0].getName().replace("$Iface", ""), bean);thriftServerProxy.start();}return BeanPostProcessor.super.postProcessAfterInitialization(bean, beanName);}
}

2.6 A服务引入含有thrift生成的service的SDK对Service进行实现

@ExtThrift(serviceName = "HelloWorldService")
@Service
public class HelloWorldServiceImpl implements HelloWorldService.Iface {@Overridepublic String sayHello(String username) throws TException {return username;}
}

@RestController
@Slf4j
public class PaymentController {@Value("${server.port}")private String serverPort;@Autowiredprivate HelloWorldService.Iface helloWorldService;@RequestMapping(value = "/payment/zk")public String paymentZk(@RequestParam("username") String username) throws TException {return "SpringCloud with zookeeper: " + serverPort + "\t" + UUID.randomUUID() + "-" + helloWorldService.sayHello(username);}
}

2.7 B服务引入含有thrift生成的service的SDK和A服务进行调用

@RestController
@Slf4j
public class OrderController {@Value("${server.port}")private String serverPort;@ImpThrift(def = "CLOUD-PAYMENT-SERVICE", serviceName = "helloWorldService")private HelloWorldService.Iface helloWorldService;@RequestMapping(value = "/payment/zk")public String paymentZk(@RequestParam("username") String username) throws TException {return "SpringCloud with zookeeper: " + serverPort + "\t" + UUID.randomUUID() + "-" + helloWorldService.sayHello(username);}
}

2.8 启动zk

zhinian@192 bin % ./zkServer.sh start
ZooKeeper JMX enabled by default
