实现RPC接口的demo记录

1.Thrift RPC 接口实现 Demo

@Service
public class DemoServiceImpl implements DemoService.Iface {

    private static final Logger logger = LoggerFactory.getLogger(DemoServiceImpl.class);

    @Override
    public String sayHello(Context context, String msg) throws TException {
        logger.info("接收到 RPC 请求, msg: {}", msg);
        return "Hello " + msg;
    }
}

2.Thrift RPC 配置 Demo

@Configuration
public class DemoThriftConfiguration {

    @Value("${rpc.server.port:9090}")
    private int port;

    /**
     * 定义 Thrift Server
     */
    @Bean
    public ServiceBuilder<DemoService.Iface> demoServer(DemoServiceImpl serviceImpl) {
        return ServiceBuilder.fromInstance(DemoService.Iface.class, port, serviceImpl);
    }


    /**
     * 定义 Thrift Client
     */
    @Bean
    public DemoService.Iface demoClient() {
        return ClientBuilder.create(DemoService.Iface.class, "excover")
                .withTimeout(2000, TimeUnit.MILLISECONDS)
                // 直连地址，仅用于本地测试；这里请求服务自己
                .withDirectHost(HostAndPort.fromParts("127.0.0.1", port))
                .buildStub();
    }
}

3.Thrift RPC Client 调用 Demo

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

    private static final Logger logger = LoggerFactory.getLogger(DemoThriftController.class);

    @Resource
    private DemoService.Iface demoClient;

    /**
     * curl http://127.0.0.1:8080/rpc/sayHello\?msg=demo
     */
    @GetMapping("/sayHello")
    public String sayHello(String msg) {
        try {
            return demoClient.sayHello(ContextHelper.getContext(), msg);
        } catch (TException e) {
            logger.error("RPC 请求失败: {}", e.getMessage(), e);
            return "error";
        }
    }
}
