Spring ProxyFactory

ProxyFactory 是 Spring AOP的实现方式之一。下面介绍下ProxyFactory的用法。

1、接口定义

public interface UserReadService { public UserInfo getUserInfoById(Long id); }

2、接口实现

public class UserReadServiceImpl implements UserReadService { @Override public UserInfo getUserInfoById(Long id) { System.out.println("获取用户信息"); return null; } }

3、拦截器定义

public class UserInterceptor implements MethodInterceptor { @Override public Object invoke(MethodInvocation invocation) throws Throwable { System.out.println("start"); Object obj = invocation.proceed(); System.out.println("end"); return obj; } }

4、测试

public static void main(String[] args) { ProxyFactory factory = new ProxyFactory(new UserReadServiceImpl()); factory.addAdvice(new UserInterceptor()); UserReadService userReadService = (UserReadService) factory.getProxy(); userReadService.getUserInfoById(null); }

 结果：

start 获取用户信息 end
