我正在尝试将Spring AOP与Spring MVC Controller一起使用。我有3个方面,并希望按照特定的顺序进行。为此,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; }
建议的班级:
@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(){} }
组态:

getOrder不能解决问题。我将不胜感激任何实用的建议,或者,如果您没有确切的答案,我将不胜感激有关Spring Proxy和编织机制的任何理论知识。
我将根据需要发布所需的任何代码/配置。谢谢阅读。
更新:1.我尝试了@Order(1),结果相同。2.我试图将方面转移到相同的程序包,它改变了它们的顺序,但是我仍然无法控制它。
您不需要实现Ordered接口。
在Spring AOP中,您可以轻松完成许多工作。
@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,将不会激活任何建议。
更新2:
我只是对此问题进行研究。@order注解仅适用于基于Spring的代理AOP(在我的示例中使用的是)。如果您使用的是编织文件,则应使用声明优先级选项。
@order
更新3
那么您需要将其配置为
<bean id="systemArchitecture" class="x.y.z.SystemArchitecture" />
我在您的代码中看不到它。
无论如何。请在Facebook上给我留言,我将向您发送一个工作示例,该示例正是您要执行的操作。
