AND、OR 和 NOT 的 Spring AOP 切入点语法 [英] Spring AOP Pointcut syntax for AND, OR and NOT
问题描述
我在 Spring(2.5.6 版)中遇到了切入点定义的问题.我正在尝试拦截对类的所有方法调用,除了给定的方法(下面示例中的 someMethod).
I'm having trouble with a pointcut definition in Spring (version 2.5.6). I'm trying to intercept all method calls to a class, except for a given method (someMethod in the example below).
<aop:config>
<aop:advisor
pointcut="execution(* x.y.z.ClassName.*(..)) AND NOT
execution(* x.y.x.ClassName.someMethod(..))"
/>
</aop:config>
但是,拦截器也会为 someMethod 调用.
However, the interceptor is invoked for someMethod as well.
然后我尝试了这个:
<aop:config>
<aop:advisor
pointcut="execution(* x.y.z.ClassName.(* AND NOT someMethod)(..)) )"
/>
</aop:config>
但这不能编译,因为它不是有效的语法(我得到一个 BeanCreationException).
But this does not compile as it is not valid syntax (I get a BeanCreationException).
谁能给点建议?
推荐答案
我知道在这个阶段它可能有点晚了,但我遇到了同样的问题,我通过转义 & 字符解决了它,所以它的 &&!
而不是 'AND NOT' 或 '&&!'.我在 xml 文件中这样做
i know its probably a bit late at this stage but ive been having the same issue and I resolved it by escaping the ampersand chars so its && !
instead of 'AND NOT' or '&& !'.
I'm doing this in the xml file
<aop:config>
<aop:pointcut id="blah" expression="execution(* com.disney.goofy..*.*(..)) && !@annotation(com.disney.goofy.NonDisneyCharacter)"/>
<aop:advisor advice-ref="transAdvice" pointcut-ref="blah"/>
</aop:config>
这将建议应用于在 com.disney.goofy 中执行且未使用 NonDisneyCharacter 注释的所有方法
This applies the advice to all methods executed in com.disney.goofy and that are not annotated with NonDisneyCharacter
