Instead,when one {@code @Bean}-method invokes another {@code @Bean}-method in lite
mode, the invocation is a standard Java method invocation; Spring does not interceptthe invocation via a CGLIB proxy.
如果@Component下使用@Bean, 并通过调用方法来获取JavaBean, 那么每次获取到都是新的JavaBean, 不是单例生产的JavaBean, 这种模式就是lite mode
, @Configuration是同一个.
