除了使用 或 在配置中声明方面之外，还可以以编程方式创建代理 建议目标对象。有关 Spring 的 AOP API 的完整详细信息，请参阅下一章。在这里，我们要重点关注自动 使用@AspectJ方面创建代理。<aop:config><aop:aspectj-autoproxy>

您可以使用该类 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，如以下示例所示：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>()
