    默认自动代理DefaultAdvisorAutoProxyCreator

    本处没有什么要讲的,放原代码

      ISomeService接口:

    package cn.dawn.day17atuo01;
    
    /**
     * Created by Dawn on 2018/3/8.
     */
    public interface ISomeService {
        public void insert();
        public void delete();
        public void select();
        public void update();
    }

      SomeServiceImpl类继承上面的那个接口:

    package cn.dawn.day17atuo01;
    
    
    /**
     * Created by Dawn on 2018/3/8.
     */
    public class SomeServiceImpl implements ISomeService{
    
        public void insert() {
            System.out.println("insert ok");
        }
    
        public void delete() {
            System.out.println("delete ok");
    
        }
    
        public void select() {
            System.out.println("select ok");
    
        }
    
        public void update() {
            System.out.println("update ok");
    
        }
    }

      LoggerBefore类,做了前置增强

    package cn.dawn.day17atuo01;
    
    
    import org.springframework.aop.MethodBeforeAdvice;
    
    import java.lang.reflect.Method;
    
    /**
     * Created by Dawn on 2018/3/5.
     */
    /*前置增强*/
    public class LoggerBefore implements MethodBeforeAdvice {
        public void before(Method method, Object[] objects, Object o) throws Throwable {
            System.out.println("日志记录");
        }
    }

      xml配置文件中

    <?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.day17atuo01.SomeServiceImpl"></bean>
        <!--增强的内容-->
        <bean id="myadvice" class="cn.dawn.day17atuo01.LoggerBefore"></bean>
        <!--顾问-->
        <bean id="myadvisor" class="org.springframework.aop.support.RegexpMethodPointcutAdvisor">
            <property name="advice" ref="myadvice"></property>
            <!--<property name="mappedNames" value="do*"></property>-->
            <!--<property name="pattern" value=".*do.*"></property>-->
            <property name="patterns" value=".*select.*"></property>
        </bean>
        <!--默认自动代理-->
        <bean class="org.springframework.aop.framework.autoproxy.DefaultAdvisorAutoProxyCreator"></bean>
    
    </beans>

      必须要有顾问,没有不可以,默认自动代理里面不用实现参数,他自动匹配

      单测方法:

    package cn.dawn.day17auto01;
    
    
    import cn.dawn.day17atuo01.ISomeService;
    import org.junit.Test;
    import org.springframework.context.ApplicationContext;
    import org.springframework.context.support.ClassPathXmlApplicationContext;
    
    /**
     * Created by Dawn on 2018/3/3.
     */
    public class test20180312 {
        @Test
        /*默认自动代理*/
        public void t01(){
            ApplicationContext context=new ClassPathXmlApplicationContext("ApplicationContext-day17auto01.xml");
            ISomeService service = (ISomeService) context.getBean("service");
    
            service.select();
    
        }
    }
