Options

1 将SpringValueProcessor中的关于自动更新的逻辑抽离到了AutoUpdateConfigChangeListener中

2 抽离了一个公共父类ApolloProcessor，用来处理反射相关的逻辑。 ApolloJsonValueProcessor,ApolloAnnotationProcessor,SpringValueProcessor都继承它 3 在PropertySourceProcessor中注册自动更新的监听器AutoUpdateConfigChangeListener 4 SpringValue增加isJson字段，表示这个属性是否是Json类型的 5 增加了单元测试
