如何在spring remoting中设置动态标头

import org.springframework.remoting.support.RemoteInvocation;
import org.springframework.remoting.support.RemoteInvocationTraceInterceptor;

public class CustomRemoteInvocationInterceptor extends RemoteInvocationTraceInterceptor {
    
    @Override
    protected void prepareRemoteInvocation(RemoteInvocation invocation) {
        super.prepareRemoteInvocation(invocation);
        
        // 设置动态标头
        invocation.addHeaderValue("CustomHeader", "CustomValue");
    }
}

<bean id="httpInvokerServiceExporter" class="org.springframework.remoting.httpinvoker.HttpInvokerServiceExporter">
    <property name="service" ref="myService"/>
    <property name="serviceInterface" value="com.example.MyService"/>
    <property name="interceptors">
        <list>
            <bean class="com.example.CustomRemoteInvocationInterceptor"/>
        </list>
    </property>
