拜托，你能帮我吗？

谢谢您。
1.我创建了一个spring集成tcp客户机上下文xml文件。

<int:gateway id="gw"
                 service-interface="com.example.demo.module.SimpleGateway"
                 default-request-channel="input"/>

    <int-ip:tcp-connection-factory id="client"
                                   type="client"
                                   host="localhost"
                                   port="1234"
                                   single-use="true"
                                   so-timeout="10000"/>

    <int:channel id="input"/>

    <int-ip:tcp-outbound-gateway id="outGateway"
                                 request-channel="input"
                                 reply-channel="clientBytes2StringChannel"
                                 connection-factory="client"
                                 request-timeout="10000"
                                 reply-timeout="10000"/>

    <int:object-to-string-transformer id="clientBytes2String"
                                      input-channel="clientBytes2StringChannel"/>

2.我创建了一个rest控制器。

@RestController
public class TcpController {

    final GenericXmlApplicationContext context;
    final SimpleGateway simpleGateway;

    public TcpController(){
        this.context = new GenericXmlApplicationContext();
        context.load("classpath:META-INF/spring/integration/tcpClientServerDemo-context.xml");
        context.registerShutdownHook();
        context.refresh();

        this.simpleGateway = context.getBean(SimpleGateway.class);
    }

    @RequestMapping("/tcp/test")
    public String test(String name) {
        //SimpleGateway simpleGateway = context.getBean(SimpleGateway.class);
        String result = simpleGateway.send(name);
        System.out.println("result : " + result);
        return result;
    }

}

3.我启动spring引导并打开1234端口（newserversocket（1234））并调用url(http://localhost：8080/tcp/测试）
4.结果是错误的。

java.lang.IllegalArgumentException: unable to determine a Message or payload parameter on method
