我正在尝试使用
Spring AOP与
Spring MVC Controller.
我有3个方面,希望按照具体的顺序.为了做到这一点,我使用Ordered接口并实现getOrder方法:

@Aspect @Component public class LoggingAspect implements Ordered{ public int getOrder() { System.out.println("Abra"); return 1; }
推荐课程:
@Component @Controller public class HomeController {
切入点:
@Aspect public class SystemArchitecture { @Pointcut("execution (* com.jajah.StorageManager.HomeController.*(..))") public void inHomeController(){} @Pointcut("execution (* com.jajah.StorageManager.HomeController.*(..))") public void loggable(){} @Pointcut("execution (* com.jajah.StorageManager.HomeController.*(..))") public void authenticated(){} }

getOrder没有办法.
我会欣赏任何实用的建议,或者如果您没有确切的答案,我将了解有关Spring Proxy和织造机制的任何理论知识.
我会根据需求发布任何代码/配置.
谢谢阅读.
更新:
我试过@Order(1),结果相同.
我试图将方面移动到同一个包,它改变了它们的顺序,但我仍然无法控制它.
解决方法
您不需要实现有序接口.
在Spring AOP中,您可以轻松地做些事情.
@Aspect @Order(1) public class AspectA { @Before("............") public void doit() {} } @Aspect @Order(2) public class AspectB { @Before(".............") public void doit() {} }
更新:
@Aspect @Order(1) public class SpringAspect { @Pointcut("within(com.vanilla.service.MyService+)") public void businessLogicMethods(){} @Around("businessLogicMethods()") public Object profile(ProceedingJoinPoint pjp) throws Throwable { System.out.println("running Advice #1"); Object output = pjp.proceed(); return output; } } @Aspect @Order(2) public class SpringAspect2 { @Pointcut("within(com.vanilla.service.MyService+)") public void businessLogicMethods(){} @Around("businessLogicMethods()") public Object profile(ProceedingJoinPoint pjp) throws Throwable { System.out.println("running Advice #2"); Object output = pjp.proceed(); return output; } }
现在应用程序上下文配置XML:
<context:annotation-config /> <aop:aspectj-autoproxy /> <bean id="springAspect" class="com.vanilla.aspect.SpringAspect" /> <bean id="springAspect2" class="com.vanilla.aspect.SpringAspect2" />
您需要通过以下方式启用AOP代理:
<aop:aspectj-autoproxy />
否则不会激活任何建议.
更新2:
我只是在研究这个问题. @order注解只适用于基于Spring的代理AOP(我在我的例子中使用).如果您正在使用编织,请使用declare precedence选项.

>我的代码中没有任何建议,只是方面和切入点.
>如果你的Advice类是:x.y.z.SystemArchitecture
那么您需要将其配置为
<bean id="systemArchitecture" class="x.y.z.SystemArchitecture" />
我的代码中没有看到它.
>“执行(* com.jajah.StorageManager.HomeController.*(..))”你的目标是什么?你能用字写吗?
无论如何.请在Facebook上给我留言,我会发送你正在做什么的工作示例.
