Spring Aop源码学习--Aop代理AopProxy

AopProxy是Spring Aop提供的代理类，简单来说通过其实现类可以获取到代理类。

AopProxy接口提供的方法如下：

public interface AopProxy {/** * Create a new proxy object. * <p>Uses the AopProxy's default class loader (if necessary for proxy creation): * usually, the thread context class loader. * @return the new proxy object (never {@code null}) * @see Thread#getContextClassLoader() *///获取一个代理对象Object getProxy();/** * Create a new proxy object. * <p>Uses the given class loader (if necessary for proxy creation). * {@code null} will simply be passed down and thus lead to the low-level * proxy facility's default, which is usually different from the default chosen * by the AopProxy implementation's {@link #getProxy()} method. * @param classLoader the class loader to create the proxy with * (or {@code null} for the low-level proxy facility's default) * @return the new proxy object (never {@code null}) *///根据类加载器获取代理对象Object getProxy(ClassLoader classLoader);}

AopProxy有两个实现类JdkDynamicAopProxy和CglibAopProxy，简单来说这两个代理类的功能就是生成目标代理类，其实现机制可以参考 Java--Proxy代理介绍及实现机制。
