Spring AOP pointcut for all methods in a controller
提问by Goose
I want to run some code before every method in a Spring (3.2.3) @Controller. I have the following defined but it won't run. I suspect the pointcut expression is incorrect.
我想在 Spring (3.2.3) @Controller 中的每个方法之前运行一些代码。我有以下定义，但它不会运行。我怀疑切入点表达式不正确。
dispatcher-servlet.xml
调度程序-servlet.xml
<aop:aspectj-autoproxy/>
<bean class="com.example.web.controllers.ThingAspect"/>
c.e.w.c.ThingAspect
事物方面
@Pointcut("execution(com.example.web.controllers.ThingController.*(..))")
public void thing() {
}
@Before("thing()")
public void doStuffBeforeThing(JoinPoint joinPoint) {
// do stuff here
}
采纳答案by kriegaex
Your pointcut expression is missing a return type like void, Stringor *, e.g.
您的切入点表达式缺少返回类型，例如void,String或*，例如
execution(* com.example.web.controllers.ThingController.*(..))

The correct way to do it in current versions of Spring MVC is through a ControllerAdvice.
See: Advising controllers with the @ControllerAdviceannotation
在当前版本的 Spring MVC 中执行此操作的正确方法是通过ControllerAdvice.
请参阅：使用@ControllerAdvice注释为控制器提供建议
For previous versions, refer to this answer of mine: https://stackoverflow.com/a/5866960/342852
对于以前的版本，请参考我的这个答案：https: //stackoverflow.com/a/5866960/342852

Besides @ControllerAdvicethat is already mentioned in another answer, you should check out Spring MVC interceptors.
除此之外@ControllerAdvice，在另一个答案中已经提到过，您应该查看Spring MVC 拦截器。
They basically simplify AOP for controllers and can be used in cases where @ControllerAdvicedoesn't give you enough power.
它们基本上简化了控制器的 AOP，可以在@ControllerAdvice没有给你足够能力的情况下使用。
