  * 动态代理实现分库
  * 动态代理适用场景更加广泛，可以实现通用分库逻辑
+ * <p>
+ * {@link ProxyFactoryBean#getObject()} 代理工厂类
+ * {@link org.springframework.aop.framework.JdkDynamicAopProxy} spring AOP实现，对动态代理封装
+ * {@link org.springframework.aop.framework.CglibAopProxy} Cglib 对类进行代理增强
+ * {@link org.apache.ibatis.binding.MapperProxyFactory#newInstance(MapperProxy)} 实现mapper代理
+ * 实际封装在 {@link MapperProxy#invoke(Object, Method, Object[])}
+ * 其获取的方法利用了享元模式 {@link MapperProxy#cachedMapperMethod(Method)}
