一、Sprig的AOP操作

JDK动态代理

//接口
package com.qfedu.demo01;
/*** @author 123*/ //LoginService接口
public interface LoginService {public void login();
}

//实现类
package com.qfedu.demo01;/*** @author 123*/
public class LoginServiceImpl implements LoginService{public void login() {System.out.println("执行login方法");}
}

package com.qfedu.demo01;import java.lang.reflect.InvocationHandler;
import java.lang.reflect.Method;public class PerformHandler implements InvocationHandler {
//    目标对象private Object target;public PerformHandler(Object target){this.target = target;}public Object invoke(Object proxy, Method method, Object[] args) throws Throwable {
//        增强的方法System.out.println("方法开始执行");
//        执行被代理类的原方法Object invoke = method.invoke(target, args);
//        增强的方法System.out.println("方法执行完毕");return invoke;}
}

//测试类
package com.qfedu.demo01;import java.lang.reflect.Proxy;public class TestPerformHandler {public static void main(String[] args) {LoginService loginService = new LoginServiceImpl();PerformHandler performHandler = new PerformHandler(loginService);
//        创建代理对象loginService = (LoginService)Proxy.newProxyInstance(loginService.getClass().getClassLoader(),loginService.getClass().getInterfaces(), performHandler);loginService.login();}
