如何在带有axon框架的java中配置不使用spring来处理命令和调度事件的聚合类？

<dependency>
    <groupId>org.axonframework</groupId>
    <artifactId>axon-core</artifactId>
    <version>4.6.3</version>
</dependency>

@Aggregate
public class MyAggregate {

    // 聚合类的状态和行为

    // 处理命令的方法

    // 处理调度事件的方法
}

@CommandHandler
public void handle(MyCommand command) {
    // 处理命令的逻辑
}

@EventSourcingHandler
public void handle(MyEvent event) {
    // 处理调度事件的逻辑
}

@Configuration
public class AxonConfig {

    @Bean
    public Configuration axonConfiguration() {
        return DefaultConfigurer.defaultConfiguration()
                .configureAggregate(MyAggregate.class)
                .buildConfiguration();
    }
}

@Service
public class MyService {

    private final CommandGateway commandGateway;
    private final EventGateway eventGateway;

    public MyService(CommandGateway commandGateway, EventGateway eventGateway) {
        this.commandGateway = commandGateway;
        this.eventGateway = eventGateway;
    }

    public void doSomething() {
        // 发送命令
        commandGateway.send(new MyCommand());

        // 发送调度事件
        eventGateway.publish(new MyEvent());
    }
}
