Binding and Binding names

绑定是一种抽象，它表示粘合剂和用户代码公开的源与目标之间的桥梁。这种抽象具有名称，虽然我们尽力限制运行 Spring Cloud Stream 应用程序所需的配置，但在需要进行额外按绑定配置的情况下，了解此类名称是必要的。

Binding is an abstraction that represents a bridge between sources and targets exposed by the binder and user code, This abstraction has a name and while we try to do our best to limit configuration required to run spring-cloud-stream applications, being aware of such name(s) is necessary for cases where additional per-binding configuration is required.

在整个手册中，你将看到配置属性的示例，例如 spring.cloud.stream.bindings.input.destination=myQueue。此属性名称中的 input 片段就是我们所说的“绑定名称”，它可以通过多种机制派生出来。以下小节将描述 Spring Cloud Stream 用于控制绑定名称的命名约定和配置元素。

Throughout this manual you will see examples of configuration properties such as spring.cloud.stream.bindings.input.destination=myQueue. The input segment in this property name is what we refer to as binding name and it could derive via several mechanisms. The following sub-sections will describe the naming conventions and configuration elements used by spring-cloud-stream to control binding names.

如果绑定名称包含特殊字符（如 . 字符），则需要用方括号 ([]) 将绑定键括起来，然后用引号将其包装起来。例如 spring.cloud.stream.bindings."[my.output.binding.key]".destination。

If your binding name has special characters, such as the . character, you need to surround the binding key with brackets ([]) and then wrap it in qoutes. For example spring.cloud.stream.bindings."[my.output.binding.key]".destination.
