The difference between aop:advisor and aop:aspect in spring AOP "love to play cool Java PHP learning path"

In spring's configuration, these two tags are used. So what's the difference?
<bean id= "Testadvice" class= "Com.myspring.app.aop.MyAdvice"/>/Slice code when using <aop:aspect> configuration, if the slice code is automatically injected to be     An, then <aop:aspect> ref attributes directly to the bean injected name on it! <aop:config> <aop:aspect ref= "Testadvice" id= "Testaspect" > <aop:pointcut expression= "(E Xecution (* com.myspring.app.aop.testpoint.* (..))) " Id= "Testpointcut"/> <aop:before method= "Dobefore" pointcut-ref= "Testpointcut"/> Ect> </aop:config>
<aop:config> <aop:pointcut expression= "(Execution (* com.myspring.app.aop.testpoint.* (..)))" Id= "MyPoint"/> <aop:advisor advice-ref= "Testadvice" pointcut-ref= "MyPoint"/> </aop:config> Note: 2 The writing order of the format. ========================================================================= package COM.MYSPRING.APP.AOP;

/** * Method Forward Notification * @author Michael * * * * * * * @Component ("myadvice")//if it is automatic assembly, the public class Myadvice can be written directly in the ref attribute when defining the slice imple     ments methodbeforeadvice{//If the Aop:advisor configuration is used, then the slice logic must implement the advice interface! Otherwise it will fail! @Override public void before (method method, object[] args, Object target) throws Throwable {System.out.printl     N ("predecessor notice"); }
If it is <aop:aspect> configuration, write a generic method, and then specify the specific method name in the slice configuration! public void Dobefore (Joinpoint point) throws Throwable {
} }
