Action 2 AOP

Spring Aop

代理机制

静态代理机制

代理对象和被代理对象必须实现同一个接口 可以按业务分开 不同服务呼叫不同业务对象

动态代理机制

设计一个类实现java.lang.reflect.InvocationHandler 于原有业务不相干 不用知道会调用谁

AOP术语

Cross-cutting concern 横切到业务流程中

Aspect 把Cross-cutting concern组织起来 设计成可重用的对象 AOP强调独立 重用时不用做任何的修改

AdviceAspect的具体实现 在java中就是具体的类

Joinpoint 插入点和时机

Pointcut组织Advice和Joinpoint

Target被Advice应用的对象和目标

Introduction 对于一个现存的类 Introduction可以增加行为 而不用修改改类的程序

Proxy

Weave Advice被应用于对象之上的过程为织入

Advice

BeforeAdvice

例子

IHello.java

package com.ergal.spring;

public interface IHello
... {
public void hello(Stringname);
}

HelloSpeaker.java

package com.ergal.spring;

public class HelloSpeaker implements IHello
... {
public void hello(Stringname)
... {
System.out.println( " hello! " + name);
}
}

在发生异常的时候同志某些服务对象做某些事

例子

IHello.java

package com.ergal.spring;

public interface IHello

public void hello(Stringname) throws Throwable;
}

HelloSpeaker.java

package com.ergal.spring;

public class HelloSpeaker implements IHello

... {
System.out.println( " hello! " + name);

throw new Exception( " 发生异常 " );
}
}

Pointcut

定义了Advice的应用时机 在Spring中 使用PointcutAdvisor 将Pointcut和Advice合成为一个对象 Spring内建的Pointcut都有对应的PointcutAdvisor

NameMatchMethodPointcutAdvisor

这是静态的

例子

IHello.java

package com.ergal.spring;

public interface IHello
... {
public void helloNewbie(Stringname);
public void helloMaster(Stringname);
}

HelloSpeaker.java

package com.ergal.spring;

public class HelloSpeaker implements IHello
... {

public void helloNewbie(Stringname)
... {
// TODOAuto-generatedmethodstub
System.out.println( " Hello! " + name + " Newbie " );
}

public void helloMaster(Stringname)
... {
// TODOAuto-generatedmethodstub
System.out.println( " Hello! " + name + " Master " );
}

}

在Eclipse下运行怎么结果不一样

ComtrolFlowPointcut

org.springframework.aop.support.ControlFlowPointcut 是Spring说提供的类 作为判断在方法的执行堆栈中 某个指定类的方法中 是否曾经要求您的目标对象执行某个动作 由于这是在执行过程中才决定是否介入Advice 所以是动态的

例子

Some.java

package com.ergal.spring;

import org.springframework.beans.BeansException;
import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationContextAware;

public class Some implements ApplicationContextAware
... {
private IHellohelloProxy;
public void setApplicationContext(ApplicationContextcontext)
throws BeansException
... {
// TODOAuto-generatedmethodstub
helloProxy = (IHello)context.getBean( " helloProxy " );

}

public void helloEveryBody()
... {
helloProxy.helloNewbie( " Wang " );
helloProxy.helloMaster( " Zhang " );
}

}

SpringDemo.java

package com.ergal.spring;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.FileSystemXmlApplicationContext;

public class SpringDemo
... {
public static void main(String[]args)
... {
ApplicationContextcontext = new FileSystemXmlApplicationContext( " beans-config.xml " );

Somesome = (Some)context.getBean( " some " );

// some.helloEveryBody();
System.out.println( " Nothing " );
}
}

beans-config.xml

<? xmlversion="1.0"encoding="UTF-8" ?>
<! DOCTYPEbeansPUBLIC"-//SPRING//DTDBEAN//EN""http://www.springframework.org/dtd/spring-beans.dtd" >

< beans >
< bean id ="some" class ="com.ergal.spring.Some" />

< bean id ="logBeforeAdvice" class ="com.ergal.spring.LogBeforeAdvice" />

< bean id ="helloSpeaker" class ="com.ergal.spring.HelloSpeaker" />

< bean id ="helloFlowControlPointcut" class ="org.springframework.aop.support.ControlFlowPointcut" >
< constructor-arg >
< value > com.ergal.spring.Some </ value >
</ constructor-arg >
</ bean >

< bean id ="helloAdvisor" class ="org.springframework.aop.support.DefaultPointcutAdvisor" >

</ property >
< property name ="interceptorNames" >

</ beans >

这样在执行方法和不执行方法的时候就有区别了 从而实现了动态的Pointcut

Introduction

追加 可以给现有的类增加方法

修改 从而分离原来的类 不影响(我是这么理解的)

比如这个类IntroductionInterceptor

例子来说明

Some.java

package com.ergal.spring;

public interface Some
... {
public void doSome();
}

Someone.java

package com.ergal.spring;

public class Someone implements Some
... {

public void doSome()
... {
// TODOAuto-generatedmethodstub
System.out.println( " 原来要做的事情......... " );
}

}

Other.java

package com.ergal.spring;

public interface Other
... {
public void doOther();
}

Otherone.java

package com.ergal.spring;

import org.aopalliance.intercept.MethodInvocation;
import org.springframework.aop.IntroductionInterceptor;

public class Otherone implements Other,IntroductionInterceptor
... {

public void doOther()
... {
// TODOAuto-generatedmethodstub
System.out.println( " 后来添加的事情进来....... " );
}

public Objectinvoke(MethodInvocationarg0) throws Throwable
... {
// TODOAuto-generatedmethodstub
if (implementsInterface(arg0.getMethod().getDeclaringClass()))
... {
return arg0.getMethod().invoke( this ,arg0.getArguments());
}
else
... {
return arg0.proceed();
}
}

public boolean implementsInterface(Classarg0)
... {
// TODOAuto-generatedmethodstub
return arg0.isAssignableFrom(Other. class );
}

}

SpringDemo.java

package com.ergal.spring;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.FileSystemXmlApplicationContext;

public class SpringDemo
... {
public static void main(String[]args)
... {
ApplicationContextcontext = new FileSystemXmlApplicationContext( " beans-config.xml " );

Somesome = (Some)context.getBean( " helloProxy " );

some.doSome();
((Other)some).doOther();
}
}
