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:
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.
