发现问题的原因可能是由于使用了Spring托管多个CommandBus实例，导致负载测试失败。因此，可以尝试使用Axon的分布式命令总线，并配置适当的RoutingStrategy，以实现负载均衡和故障转移。以下是使用Axon Server作为分布式命令总线和Spring Boot的配置示例：

// 在Spring Boot中配置Axon Server
@Configuration
public class AxonConfig {

    @Bean
    public SpringAxonAutoConfigurer axonAutoConfigurer() {
        return new SpringAxonAutoConfigurer();
    }

    @Bean
    public ServerAddress axonServerAddress() {
        return ServerAddress.newBuilder()
                .host("localhost") // Axon Server的主机名或IP地址
                .port(8124) // Axon Server的端口号
                .build();
    }

    @Bean
    public AxonServerConfiguration axonServerConfiguration(ServerAddress axonServerAddress) {
        return AxonServerConfiguration.newBuilder()
                .servers(axonServerAddress)
                .componentName("MyAxonApp") // Axon组件的名称
                .build();
    }

    @Bean
    public EventProcessorConfigurer eventProcessorConfigurer(ClusterSelectorConfigurer clusterSelectorConfigurer) {
        return new EventProcessorConfigurer() {
            @Override
            public void configureEventProcessor(EventProcessingConfigurer eventProcessingConfigurer) {
                // 配置分布式命令总线和事件总线
                eventProcessingConfigurer.usingTrackingProcessors();
                eventProcessingConfigurer.usingSubscribingEventProcessors();

                // 配置负载均衡
                ClusterSelector loadBalancingSelector = clusterSelectorConfigurer.buildLoadBalancingSelector();
                eventProcessingConfigurer.registerDefaultHandlerInterceptor((unitOfWork, interceptorChain) -> {
                    unitOfWork.transformMessage(o -> {
                        if (o instanceof CommandMessage) {
                            CommandMessage commandMessage = (CommandMessage) o;
                            return commandMessage.andMetaData(Map.of(ClusterSelector.KEY, loadBalancingSelector));
                        }
                        return o;
                    });
                    return interceptorChain.pro
