我是新来的雅瓦人,曾经很惊讶。 所以也许这在雅瓦人中是可能的?
我有课课
class X {
string method_a(int x) {
String str="abc";
return str;
}
}
class Y {
void before(){};
void after(){};
}
我可以告诉爪哇在X类的“方法”之前或之后叫Y类“之前”和“之后”的方法吗?
感谢 谢谢

听上去你想要"http://en.wikipedia.org/wiki/Aspect-fo方向_programing" rel=“nofollow” >Aspect-ofofed productproduct 。这不是作为“正常” Java 的一部分存在的东西, 但周围有各种各样的技术来帮助它。您可能想要从开始, http://www. eclipse.org/aspectj/"rel=“nofolfollow” >AspectJ 。
您所要的不是语言本身的支持,但可以通过以下框架提供,例如 Spring s Aspect Oriend Programme 模型 。
是的, 您可以。 它叫做“ 目标 ” ( 搜索 AspectJ ) 。 我找到了这个为您介绍的喜好世界的例子 : < a href=" http:// www.java2s.com/Code/ Java/ Spring/ AspectHelloWorldExample.htm" rel=“ nofollow” > http:// www.java2s.com/Code/ Java/Spring/AspectHelloWorldExample.htm
我不得不警告你,有些方面对于伐木和业绩追踪效果很好,但如果使用错误,则可能成为恶梦。 正如他们说的 : “ 强权带来巨大的责任 ” 。
