Another problem is that the crosscutting views only show matches based on static join point shadows.

In these cases you can query the object representing the advised join point for its associated annotations.
在这种情况下，可以查询表示已通知连接点的对象来获得相关的注释。
It is as general as a join point, safer than advice (because the context is more hidden), and as reusable as Command.
它和连接点一样通用，比通知更安全(因为上下文更加隐蔽)，并且和Command一样可以重用。
Next, I'll quickly review the basics of AOP's join point model and explain where it would benefit from metadata fortification.
下一步，我将快速地回顾AOP的连接点模型的基本内容，并说明它从元数据增强中可以获得哪些好处。
Precondition tests are handled by before advice, which is executed just before the corresponding method execution join point.
前置条件测试由before建议处理，该建议就在对应的方法执行连接点之前执行。
The second statement identifies the exact join point where the advice is executed and makes use of the AspectJ JoinPoint class.
第二条语句指明了通知被执行的确切连接点，并且应用了AspectJ的joinpoint类。
At the heart of each of the AOP tools is a join point model, which provides a means of identifying where the crosscutting is happening.
位于每个AOP工具核心的是连接点模型，它提供了一种机制，可以识别出在哪里发生了横切。
It is used to indicate either that the given element is being affected by advice directly, or that it contains a join point that is being advised.
可用它表示指定元素是否受通知的直接影响，或者是否包含正被通知的连接点。
The expressiveness of an AOP tool's join point model determines the granularity of the join points available, and how those join points are matched.
一个AOP工具连接点模型的表达方式决定了可用的连接点粒度，以及连接点如何匹配。
The join point models of AspectJ and AspectWerkz have converged almost completely, and this has been one of the key enablers of the recent merger.

How does this interact with other kinds of tests at the join point, with other advice at the join point, and with any code that runs the join point?
如何与连接点上的其他测试类型、其他通知、运行该连接点的其他代码交互呢？
In the next section I'll quickly review the basics of AOP's join point model, then explain where it could be beneficially fortified with metadata.
在下一节中，我将快速地回顾AOP的连接点模型(join point model)的基本内容，然后说明是如何用元数据增强它。
With a metadata-based subaspect, when a join point in a class changes its characteristics only the annotation for the join point needs to be changed.
利用基于元数据的子方面，当类中的连接点改变其特性时，只有这个连接点的注释需要改变。
Each of the AOP tools reviewed in this article employs a join point model and mechanisms for explicitly declaring a program's crosscutting structure.
本文介绍的每个AOP工具都采用了连接点(join point)模型和机制，显式地声明程序的横切结构。
The join point model, the most fundamental and distinguishing concept in AOP, defines which join points in a system are exposed and how they are captured.
连接点模型是AOP中最基本和最独特的概念，它定义了系统中哪个连接点是公开的，以及如何捕获它们。
First, you can configure the join point directly by varying some context available at the join point, like method arguments or the executing object itself.
