Spring aop-@around错误：：0在pointcut中正式未绑定

Question

我已经看了其他的问题，没有一个适用。你有没有想过为什么之前有效，而周围不有效？

在这里使用源代码:http://www.captaindebug.com/2013/07/audity-spring-mvc-webapp-with-aspectj.html#.vhueixnviko

@Before("execution(public String com.captaindebug.audit.controller.*Controller.*(..)) && @annotation(auditAnnotation)")
        public void auditScreen(JoinPoint joinPoint,Audit auditAnnotation) {...}

@Around("execution(public String com.captaindebug.audit.controller.*Controller.*(..)) && @annotation(auditAnnotation)")
public void profile(ProceedingJoinPoint pjp, Audit auditAnnotation) throws Throwable {...)

    @Pointcut("execution(public String com.captaindebug.audit.controller.*Controller.*(..))")
    public void controllerMethods() {}

    @Around("controllerMethods()")
    public void profile(ProceedingJoinPoint pjp) throws Throwable {}

Answer 1

@around必须返回一些内容。

public Object profile(ProceedingJoinPoint pjp, Audit auditAnnotation) throws Throwable {
  ...
  Object retVal = pjp.proceed();
  ...
  return retVal;
}
