2.1　　类的方式实现各种通知

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.save();
    }
    
    
}

实体类：

package com.imooc.aop.api;

public class BizLogicImpl implements BizLogic{

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

}

接口类：

package com.imooc.aop.api;

public interface BizLogic {
    String save();
}

前置通知：

package com.imooc.aop.api;

import java.lang.reflect.Method;

import org.springframework.aop.MethodBeforeAdvice;

public class MoocBeforeAdvice implements MethodBeforeAdvice{
    
    /**
     * 实现MethodBeforeAdvice接口，可以在连接点之前执行
     * 
     * 
     * 作用是什么？
     * 将前一章中的xml配置方式改为了实现接口的实现方式 具体细节和使用参考开发文档
     * 
     */
    @Override
    public void before(Method method, Object[] aobj, Object obj)
            throws Throwable {
        System.out.println("MoocBeforeAdvice:"+method.getName()+"     "+
                obj.getClass().getName());
    }

}

后置通知：

package com.imooc.aop.api;

import java.lang.reflect.Method;

import org.springframework.aop.AfterReturningAdvice;

/**
 * 实现AfterReturningAdvice接口，可以在连接点之后执行
 * @author weijingli
 *
 */
public class MoocAfterReturningAdvice implements AfterReturningAdvice{

    /**
     * obj 作为输出
     */
    @Override
    public void afterReturning(Object obj, Method method, Object[] aobj,
            Object obj1) throws Throwable {
        System.out.println("MoocAfterReturningAdvice:"+method.getName()+
                "    类的名称："+obj1.getClass().getName()+"    "+obj);
    }

}

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;
    }

}

异常通知：

package com.imooc.aop.api;

import java.lang.reflect.Method;

import org.springframework.aop.ThrowsAdvice;

/**
 * 引入spring aop jar包  ，实现 ThrowsAdvice 接口
 * 实现异常通知
 * 
 * 可以一参，可以多参
 * @author weijingli
 *
 */
public class MoocThrowsAdvice implements ThrowsAdvice{
    
    /**
     * 
     * @param ex
     * @throws Throwable
     */
    public void afterThrowing(Exception ex) throws Throwable{
        System.out.println("MoocThrowAdvice afterThrowiing1");
    }
    
    
    public void afterThrowing(Method method,Object[] args,Object target,Exception ex) throws Throwable{
        System.out.println("MoocThrowAdvice afterThrowiing2："+method.getName()+"    "
                +target.getClass().getName());
    }
}
