系统初始化RedisMessageListenerContainer bean 放到系统启动处

    @Bean
    public RedisMessageListenerContainer container(RedisConnectionFactory redisConnectionFactory) {
        RedisMessageListenerContainer container = new RedisMessageListenerContainer();
        container.setConnectionFactory(redisConnectionFactory);
        return container;
    }
