4：Around advice

这个advice 联合了上面的三个advices，在方法执行期间执行，创建一个类实现MethodInterceptor接口，需要在方法中执行Object result = methodInvocation.proceed();方法才能得到执行，否则方法不会执行。

类如下：

[java]

package com.myapp.core.aop.advice;

import java.util.Arrays;

import org.aopalliance.intercept.MethodInterceptor;

import org.aopalliance.intercept.MethodInvocation;

public class AroundMethod implements MethodInterceptor{

@Override

public Object invoke(MethodInvocation methodInvocation) throws Throwable {

// TODO Auto-generated method stub

System.out.println("method name:" + methodInvocation.getMethod().getName());

System.out.println("method arguments" + Arrays.toString(methodInvocation.getArguments()));

System.out.println("Around method : before ");

try{

Object result = methodInvocation.proceed();

System.out.println("Around method : after ");

return result;

}catch(IllegalArgumentException e){

System.out.println("Around method : throw an exception ");

throw e;

}

}

}
