想做一个Spring AOP的例子,可是怎么也出不来结果,程序也不报错!
我在练习aop的helloworld的例子的时候,按你的aop标签配置的方式,总是无法拦截到方法执行前和执行后。程序执行结果只是打印helloworld。也没有报告错误。
另外,spring3.2.3已经不提供dependencies包了,我把之前版本的dependencies包中相关的jar都放到了目录下了。您估计是怎么回事呢?怎么拦截不到呢?
谢谢!
package a;
public interface IHelloService {
public void sayHello();
}
package a;
public class HelloService implements IHelloService {
@Override
public void sayHello() {
// TODO Auto-generated method stub
System.out.println("Hello World!");
}
}
package a;
public class HelloWorldAspect {
public void beforeAdvice()
{
System.out.println("befor advice");
}
public void afterAdvice()
{
System.out.println("after Advice");
}
}
