《Pro Spring》学习笔记之JdkRegexpMethodPointCut正则表达式切入点实例

如果我们想对所有以中间由foo组成的方法进切入（比如afooa为方法名），我们可以使用JdkRegexpMethodPointCut(JDK正则表达式方法切入点)，也可以使用Perl5RegexpMethodPointCut（Perl5切入点正则表达式）

Bean:

 

package ch6.SimpleAOP.RegexpPointCut;

public class BeanOne {
   public void afooa(){
    System.out.println("afooa");
   }
   public void bfoob(){
    System.out.println("bfoob");
   }
   public void abara(){
    System.out.println("abara");
   }
}

 

SimpleAdvise

 

package ch6.SimpleAOP.RegexpPointCut;

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

public class SimpleAdvise implements MethodInterceptor ...{

    public Object invoke(MethodInvocation invocation) throws Throwable ...{
        System.out.println("before");
        Object retVal=invocation.proceed();
        System.out.println("after");
        return retVal;
    }

}

 

测试：

 

package ch6.SimpleAOP.RegexpPointCut;

import org.aopalliance.aop.Advice;
import org.springframework.aop.Advisor;
import org.springframework.aop.Pointcut;
import org.springframework.aop.framework.ProxyFactory;
import org.springframework.aop.support.DefaultPointcutAdvisor;
import org.springframework.aop.support.JdkRegexpMethodPointcut;
import org.springframework.aop.support.NameMatchMethodPointcut;

public class Test ...{

    /** *//**
     * @param args
     */
    public static void main(String[] args) ...{
         BeanOne one=new BeanOne();
        
         BeanOne proxyOne;
         
         
         JdkRegexpMethodPointcut pc=new JdkRegexpMethodPointcut();
         pc.setPattern(".*foo.*");
         
         Advice advice=new SimpleAdvise();
         Advisor advisor=new DefaultPointcutAdvisor(pc,advice);
         
         
         //创建BeanOne代理
         ProxyFactory pf1=new ProxyFactory();
         pf1.addAdvisor(advisor);
         pf1.setTarget(one);
         proxyOne=(BeanOne)pf1.getProxy();
         
      
         
         
         proxyOne.afooa();
         proxyOne.bfoob();
         proxyOne.abara();
         
    }

}

 

结果：

before
afooa
after
before
abfoob
after
abara
