测试类：

package com.imooc.test.aop;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.junit.runners.BlockJUnit4ClassRunner;

import com.imooc.aop.api.BizLogic;
import com.imooc.test.base.UnitTestBase;

@RunWith(BlockJUnit4ClassRunner.class)
public class TestAOPAPI extends UnitTestBase{

    public TestAOPAPI() {
        super("classpath:spring-aop-api.xml");
        // TODO Auto-generated constructor stub
    }
    
    @Test
    public void testSave(){
        BizLogic bLogic = super.getbean("bizLogicImpl");
        bLogic.sove();
    }

实现类：

package com.imooc.aop.api;

public class BizLogicImpl implements BizLogic{

    @Override
    public String sove() {
        System.out.println("syso save");
        return "BizLogicImpl save";
    }
    

}

接口：

package com.imooc.aop.api;

public interface BizLogic {
    String sove();
}

环绕通知：

package com.imooc.aop.api;

import org.aopalliance.intercept.MethodInterceptor;
import org.aopalliance.intercept.MethodInvocation;

/**
 * 引入环绕通知
 * 
 * 实现  MethodInterceptor 接口
 * @author weijingli
 *
 */
public class MoocMethodInterceptor implements MethodInterceptor{

    @Override
    public Object invoke(MethodInvocation methodinvocation) throws Throwable {
        
        //实现前置通知的方法
        //得到方法    得到类
        System.out.println("MoocMethodInterceptor1:"+methodinvocation.getMethod().getName()+" " +methodinvocation.getStaticPart().getClass().getName());
        
        Object obj = methodinvocation.proceed();
        
        //实现后置通知方法
        System.out.println("MoocMethodInterceptor2:"+obj); return obj;
    }

}
