JDK动态代理_编码实现
====================

/src/test/java/cn/tedu/proxy/JDKProxyTest.java：

public class JDKProxyTest {
    public static void main(String[] args) {
        Logger logger = Logger.getLogger(JDKProxyTest.class);

        UserService userService = new UserServiceImpl();

        UserService userServiceProxy = (UserService) Proxy.newProxyInstance(
            JDKProxyTest.class.getClassLoader(),
            userService.getClass().getInterfaces(),
            new InvocationHandler() {
                @Override
                public Object invoke(Object proxy, Method method,
                                     Object[] args) throws Throwable {
                    Object object = null;
                    try {
                        logger.debug(">>>> BEFORE INVOKE >>>>");
                        object = method.invoke(userService, args);
                        logger.debug("<<<< AFTER INVOKE <<<<");
                    } catch (Throwable throwable) {
                        throwable.printStackTrace();
                    }
                    return object;
                }
            });

        userServiceProxy.register(new User("zhangfei", "123456"));
        userServiceProxy.login("zhangfei", "123456");
    }
}

>>>> BEFORE INVOKE >>>>
UserServiceImpl.register
<<<< AFTER INVOKE <<<<
>>>> BEFORE INVOKE >>>>
UserServiceImpl.login
<<<< AFTER INVOKE <<<<
