关于Spring 基于由头的AOP报错

热度:179   发布时间:2016-04-21 23:46:09.0
关于Spring 基于借口的AOP报错
@Before("execution(* com.spring.Master.*(..))")
Master是一个类,实现了MyInterface这个借口,按照上面这样写不报错,一切正常
但是把Master换成MyInterface就报错了,,求各位大神看下问题在哪

主要代码如下
public interface WorkInterface {
public void dowork();
}


@Component("master")
public class Master implements WorkInterface{

@Override
public void dowork() {
// TODO Auto-generated method stub
System.out.println("Working after meal...");
}

}


public class DynamicProxyFactory{
@Resource
private Servant servant;

// @Before("execution(* com.spring.WorkInterface.*(..))")
@Before("execution(* com.spring.Master.*(..))")
public void before(){
servant.dowork();
}
}


public class Test {
public static void main(String[] args) {
BeanFactory factory=new ClassPathXmlApplicationContext("applicationContext.xml");
WorkInterface master=(WorkInterface)factory.getBean("master");
master.dowork();
}
}

    <!-- 启用组件扫描 -->
<context:component-scan base-package="com.spring"/>
<!-- 启用注解注入 -->
<context:annotation-config/>
<!-- 启用AspectJ的-->
<aop:aspectj-autoproxy />
</beans>

------解决方案--------------------
看错误日志是: 注入 Servant 的时候生成的代理对象和Servant类型不匹配造成的错误。用servant的接口试试
------解决方案--------------------
将这里的
public?class?DynamicProxyFactory{
????@Resource
????private?Servant?servant;

Servant servant; 改成 WorkInterface servant;

其他有 @Resource 及@Autowired 的地方都要改。
