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

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(); } }
