Spring AOP - @Around Error at ::0 切入点正式未绑定

Question

我查看了其他 SO 问题，其中 none 个适用。关于为什么 @Before 有效，但 @Around 无效的任何想法？

在此处处理源代码： http://www.captaindebug.com/2013/07/auditing-spring-mvc-webapp-with-aspectj.html#.VhUeIxNViko

这很好用：

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

但这失败并出现错误：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'mvcContentNegotiationManager': Initialization of bean failed; nested exception is java.lang.IllegalArgumentException: error at ::0 formal unbound in pointcut

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

这也没有用：

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

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

Answer 1

也许你可以尝试像这样拆分切入点定义和方面？

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

@Pointcut("@annotation(auditAnnotation)")
public void annotatedMethod(Audit auditAnnotation) {}

@Pointcut("annotatedMethod() && controllerMethods()")
public void annotationDrivenControllerMethodsPointcut() {}

@Around("annotationDrivenControllerMethodsPointcut()")
public void profile(ProceedingJoinPoint pjp, Audit auditAnnotation) throws Throwable {...)

来自 Pointcut javadoc 文档的一些细节

When compiling without debug info, or when interpreting pointcuts at runtime, the names of any arguments used in the pointcut are not available.

Answer 2

@Around 必须 return 一些东西。

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

Answer 3

After my repeated tests 经过我的反复测试 @Around(value ="@annotation(oneAnnotaions) && args(object,..) ",argNames = "joinPoint,object," + "oneAnnotaions") public Object around(ProceedingJoinPoint joinPoint,Object object,com.xxx.annotaions.OneAnnotaions oneAnnotaions)

Answer 4

After my repeated tests
经过我的反复测试
  @Around(value ="@annotation(oneAnnotaions) && args(object,..) ",argNames = "joinPoint,object," +
            "oneAnnotaions")
    public Object around(ProceedingJoinPoint joinPoint,Object object,com.xxx.annotaions.OneAnnotaions oneAnnotaions)
