Question

我在基于spring mvc的应用程序中使用Aspect来记录活动。我正在使用 @controller 注释来定义我的应用程序中的任何控制器。我在两个不同的包中有两个不同的控制器说

com.package1包含控制器1类，我们将其命名为AController
com.package2包含控制器2类，我们将其命名为BController

我可以使用

将aspect应用于一个特定的控制器包

<aop:config>
    <aop:pointcut id="pointcut1"
        expression="execution(* package1.*.*(..))"
        id="policy1" />
    <aop:aspect ref="aspect1" order="1">
        <aop:before pointcut-ref="pointcut1" method="before" arg-names="joinPoint" />
        <aop:after-returning returning="returnValue" arg-names="joinPoint, returnValue" pointcut-ref="pointcut1" method="after"  />
    </aop:aspect>
</aop:config>


<bean id="aspect1" class="com......aspectclass" />

我的问题是如何在表达式中指定更多一个不同的包（* package1。。 。（..））**

现在我正在为每个包声明一个单独的切入点，并为每个切入点分别设置一个aop:before和aop:after条目。但我认为这应该是定义多个包切入点的理想方式。

Answer 1

您可以使用布尔运算符：

expression="execution(* package1.*.*(..)) || execution(* package2.*.*(..))"

Answer 2

如果您使用注释

@Pointcut("within(com.package1..*) || within(com.package2..*)")

Answer 4

  @Pointcut("execution(* pakageName.anyClassNameX.*(..)) || execution(* pakageName.anyClassNameY.*(..))")
  public void allMethods() {
  }

  @Around("allMethods()")
  public Object intercept(ProceedingJoinPoint thisJoinPoint) throws Throwable {
    try {
      return thisJoinPoint.proceed();
    } catch (Exception ex) {
     
    }
  }
