方法详细资料

• currentJoinPoint

  public static org.aspectj.lang.JoinPoint currentJoinPoint()

  Lazily instantiate joinpoint for the current invocation. Requires MethodInvocation to be bound with ExposeInvocationInterceptor.

  Do not use if access is available to the current ReflectiveMethodInvocation (in an around advice).

  返回:

  current AspectJ joinpoint, or through an exception if we're not in a Spring AOP invocation.

• getAspectJAdviceMethod

  public final Method getAspectJAdviceMethod()

  Return the AspectJ-style advice method.

• getPointcut

  public final AspectJExpressionPointcut getPointcut()

  Return the AspectJ expression pointcut.

• buildSafePointcut

  public final Pointcut buildSafePointcut()

  Build a 'safe' pointcut that excludes the AspectJ advice method itself.

  返回:

  a composable pointcut that builds on the original AspectJ expression pointcut

  getPointcut()

• getAspectInstanceFactory

  public final AspectInstanceFactory getAspectInstanceFactory()

  Return the factory for aspect instances.

• getAspectClassLoader

  @Nullable
  public final ClassLoader getAspectClassLoader()

  Return the ClassLoader for aspect instances.

• getOrder

  public int getOrder()

  从接口复制的说明: Ordered
  Get the order value of this object.

  Higher values are interpreted as lower priority. As a consequence, the object with the lowest value has the highest priority (somewhat analogous to Servlet load-on-startup values).

  Same order values will result in arbitrary sort positions for the affected objects.

  指定者:

  getOrder 在接口中 Ordered

  返回:

  the order value

  另请参阅:

  Ordered.HIGHEST_PRECEDENCE, Ordered.LOWEST_PRECEDENCE

• setAspectName

  public void setAspectName​(String name)

  Set the name of the aspect (bean) in which the advice was declared.

• getAspectName

  public String getAspectName()

  从接口复制的说明: AspectJPrecedenceInformation
  Return the name of the aspect (bean) in which the advice was declared.

  指定者:

  getAspectName 在接口中 AspectJPrecedenceInformation

• setDeclarationOrder

  public void setDeclarationOrder​(int order)

  Set the declaration order of this advice within the aspect.

• getDeclarationOrder

  public int getDeclarationOrder()

  从接口复制的说明: AspectJPrecedenceInformation
  Return the declaration order of the advice member within the aspect.

  指定者:

  getDeclarationOrder 在接口中 AspectJPrecedenceInformation

• setArgumentNames

  public void setArgumentNames​(String argNames)

  Set by creator of this advice object if the argument names are known.

  This could be for example because they have been explicitly specified in XML, or in an advice annotation.

  参数:

  argNames - comma delimited list of arg names

• setArgumentNamesFromStringArray

  public void setArgumentNamesFromStringArray​(String... args)

• setReturningName

  public void setReturningName​(String name)

• setReturningNameNoCheck

  protected void setReturningNameNoCheck​(String name)

  We need to hold the returning name at this level for argument binding calculations, this method allows the afterReturning advice subclass to set the name.

• getDiscoveredReturningType

  protected Class<?> getDiscoveredReturningType()

• getDiscoveredReturningGenericType

  @Nullable
  protected Type getDiscoveredReturningGenericType()

• setThrowingName

  public void setThrowingName​(String name)

• setThrowingNameNoCheck

  protected void setThrowingNameNoCheck​(String name)

  We need to hold the throwing name at this level for argument binding calculations, this method allows the afterThrowing advice subclass to set the name.

• getDiscoveredThrowingType

  protected Class<?> getDiscoveredThrowingType()

• calculateArgumentBindings

  public final void calculateArgumentBindings()

  Do as much work as we can as part of the set-up so that argument binding on subsequent advice invocations can be as fast as possible.

  If the first argument is of type JoinPoint or ProceedingJoinPoint then we pass a JoinPoint in that position (ProceedingJoinPoint for around advice).

  If the first argument is of type JoinPoint.StaticPart then we pass a JoinPoint.StaticPart in that position.

  Remaining arguments have to be bound by pointcut evaluation at a given join point. We will get back a map from argument name to value. We need to calculate which advice parameter needs to be bound to which argument name. There are multiple strategies for determining this binding, which are arranged in a ChainOfResponsibility.

• supportsProceedingJoinPoint

  protected boolean supportsProceedingJoinPoint()

• createParameterNameDiscoverer

  protected ParameterNameDiscoverer createParameterNameDiscoverer()

  Create a ParameterNameDiscoverer to be used for argument binding.

  The default implementation creates a DefaultParameterNameDiscoverer and adds a specifically configured AspectJAdviceParameterNameDiscoverer.

• argBinding

  protected Object[] argBinding​(org.aspectj.lang.JoinPoint jp,

  Take the arguments at the method execution join point and output a set of arguments to the advice method.

  参数:

  jp - the current JoinPoint

  jpMatch - the join point match that matched this execution join point

  returnValue - the return value from the method execution (may be null)

  ex - the exception thrown by the method execution (may be null)

  返回:

  the empty array if there are no arguments
