一、Thrift 基操实现
1.1 thrift文件
namespace java com.zn.opit.thrift.helloworld
service 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

1.3 实现HelloWorldService
public class HelloWordServiceImpl implements HelloWorldService.Iface {
@Override
public String sayHello(String username) throws TException {
return "hello, " + username;
}
}
1.4 服务端
@Slf4j
public class ThriftServer {
public static final int SERVER_PORT = 8010;
public static void main(String[] args) throws Exception {
log.info("服务端开启....");
// 启动服务
new TSimpleServer(new TServer.Args(new TServerSocket(new ServerSocket(SERVER_PORT)))
.processor(new HelloWorldService.Processor<HelloWorldService.Iface>(new HelloWordServiceImpl()))
.protocolFactory(new TBinaryProtocol.Factory())).serve();
}
}
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class
Class 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 {
@Resource
private DiscoveryClient discoveryClient;
@Override
public 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 {
@Override
public 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("$Iface", ""), bean);
thriftServerProxy.start();
}
return BeanPostProcessor.super.postProcessAfterInitialization(bean, beanName);
}
}
2.6 A服务引入含有thrift生成的service的SDK对Service进行实现
@ExtThrift(serviceName = "HelloWorldService")
@Service
public class HelloWorldServiceImpl implements HelloWorldService.Iface {
@Override
public String sayHello(String username) throws TException {
return username;
}
}
@RestController
@Slf4j
public class PaymentController {
@Value("${server.port}")
private String serverPort;
@Autowired
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);
}
}
2.7 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
Using config: /Users/zhinian/Desktop/tools/zookeeper-3.4.11/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED
2.9 启动AB服务进行测试
调用成功 !
