apollo 是否需要支持自动刷新配置类

[gy09535]

你的特性请求和某个问题有关吗？请描述
如 demo 所示：https://github.com/apolloconfig/apollo/blob/master/apollo-demo/src/main/java/com/ctrip/framework/apollo/demo/spring/springBootDemo/config/SampleRedisConfig.java

如果我想刷新这部分的配置，我需要手动写一个监听器去刷新，可不可以不用写监听器，直接就可以刷新配置。不包含额外的注解，比如：从 nacos 配置中心迁移到 apollo 当中，如果修改量较大的话，改起来还是比较麻烦的，怎样的实践比较正确呢？
