Examples of Valve

com.alibaba.citrus.service.pipeline.Valve
代表pipeline中的一个“阀门”。
如同真实世界里的水管中的阀门，它可以控制和改变液体的流向，Valve 也可以控制pipeline中后续valves的执行。 Valve可以决定是否继续执行后续的valves，或是中断整个pipeline的执行。

A Valve is a request processing component associated with a particular Container. A series of Valves are generally associated with each other into a Pipeline. The detailed contract for a Valve is included in the description of the invoke() method below.

A Valve is a request processing component associated with a particular Container. A series of Valves may be associated with the same Container, creating a request processing pipeline.
