我有一个uml图如下：

如何在状态机中根据事件配置从si到end的状态和转换。。。。

public class Config14
            extends EnumStateMachineConfigurerAdapter<States, Events> {

        @Override
        public void configure(StateMachineStateConfigurer<States, Events> states)
                throws Exception {
                                  .....

}

    @Override
            public void configure(StateMachineTransitionConfigurer<States, Events> transitions)
                    throws Exception {
                                   .....
    }
}
