    RegexpMethodPointcutAdvisor:正则方法切入点顾问

      核心:

      <property name="pattern" value=".*do.*"></property> 表示方法全名(包名,接口名,方法名)
      运算符    名称     意义
      .        点号      表示任意单个字符
      +       加号      表示前一个字符出现一次或者多次
      *       星号      表示前一个字符出现0次或者多次

      具体使用案例:

      一个实现俩个方法的类:SomeServiceImpl

    package cn.dawn.day16advisor02;
    
    
    /**
     * Created by Dawn on 2018/3/8.
     */
    public class SomeServiceImpl {
        public void doSome() {
            System.out.println("do something");
        }
        public void doAny() {
            System.out.println("do Any");
        }
    }

      一个实现任意增强的接口的方法:此处是实现后置增强的,我起名LoggerAfter

    package cn.dawn.day16advisor02;
    
    import org.springframework.aop.AfterReturningAdvice;
    
    import java.lang.reflect.Method;
    
    /**
     * Created by Dawn on 2018/3/5.
     */
    /*后置增强*/
    public class LoggerAfter implements AfterReturningAdvice {
        public void afterReturning(Object o, Method method, Object[] objects, Object o1) throws Throwable {
            System.out.println("===============after==================");
        }
    }

      大配置文件:

    <?xml version="1.0" encoding="UTF-8"?>
    <beans xmlns="http://www.springframework.org/schema/beans"
           xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
           xmlns:aop="http://www.springframework.org/schema/aop"
           xmlns:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context"
           xsi:schemaLocation="http://www.springframework.org/schema/beans
           http://www.springframework.org/schema/beans/spring-beans.xsd
           http://www.springframework.org/schema/aop
           http://www.springframework.org/schema/aop/spring-aop.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">
        <!--要增强的对象-->
        <bean id="service" class="cn.dawn.day16advisor02.SomeServiceImpl"></bean>
        <!--增强的内容-->
        <bean id="myadvice" class="cn.dawn.day16advisor02.LoggerAfter"></bean>
        <!--顾问-->
        <bean id="myadvisor" class="org.springframework.aop.support.RegexpMethodPointcutAdvisor">
            <property name="advice" ref="myadvice"></property>
            <property name="pattern" value=".*do.*"></property>
            <!--上面那个name还有一个可以是patterns,value可以写多个正则。用逗号分割,匹配多个正则,方法名只要合适其中一个正则就增强-->
        </bean>
        <!--代理工厂bean-->
        <bean id="proxyfactory" class="org.springframework.aop.framework.ProxyFactoryBean">
            <!--要增强的对象-->
            <property name="target" ref="service"></property>
            <!--增强的内容-->
            <property name="interceptorNames" value="myadvisor"></property>
        </bean>
    
    </beans>

      单测方法:

    package cn.dawn.day16advisor02;
    
    
    import org.junit.Test;
    import org.springframework.context.ApplicationContext;
    import org.springframework.context.support.ClassPathXmlApplicationContext;
    
    /**
     * Created by Dawn on 2018/3/3.
     */
    public class test20180310 {
        @Test
        /*aop代理工厂bean异常增强*/
        public void t01(){
            ApplicationContext context=new ClassPathXmlApplicationContext("ApplicationContext-day16advisor02.xml");
            SomeServiceImpl service = (SomeServiceImpl) context.getBean("proxyfactory");
    
            service.doSome();
            service.doAny();
    
        }
    }
