除了使用 or 在配置中声明 aspects 之外，还可以以编程方式创建代理
通知目标对象。有关 Spring 的 AOP API 的完整详细信息，请参见下一章。在这里，我们想重点介绍自动
使用 @AspectJ 方面创建代理。<aop:config><aop:aspectj-autoproxy>
您可以使用 class
为一个或多个 @AspectJ 方面建议的目标对象创建代理。
此类的基本用法非常简单，如下例所示：org.springframework.aop.aspectj.annotation.AspectJProxyFactory
-
Java
-
Kotlin
// create a factory that can generate a proxy for the given target object
AspectJProxyFactory factory = new AspectJProxyFactory(targetObject);
// add an aspect, the class must be an @AspectJ aspect
// you can call this as many times as you need with different aspects
factory.addAspect(SecurityManager.class);
// you can also add existing aspect instances, the type of the object supplied
// must be an @AspectJ aspect
factory.addAspect(usageTracker);
// now get the proxy object...
MyInterfaceType proxy = factory.getProxy();// create a factory that can generate a proxy for the given target object
val factory = AspectJProxyFactory(targetObject)
// add an aspect, the class must be an @AspectJ aspect
// you can call this as many times as you need with different aspects
factory.addAspect(SecurityManager::class.java)
// you can also add existing aspect instances, the type of the object supplied
// must be an @AspectJ aspect
factory.addAspect(usageTracker)
// now get the proxy object...
val proxy = factory.getProxy<Any>()有关更多信息，请参阅 javadoc。
