Annotation
当 @Command 注解被用于某个方法时，它将该方法标记为命令注册的候选方法。在下例中，命令 example 被定义。
@Command annotation when used on a method marks it as a candidate for command registration.
In below example a command example is defined.
Unresolved include directive in modules/ROOT/pages/commands/registration/annotation.adoc - include::../../test/java/org/springframework/shell/docs/CommandAnnotationSnippets.java[]@Command 注解可以被放置在一个类上，该类定义了在同一个类中定义的 @Command 方法的默认设置或共享设置。在下例中，命令 parent example 被定义。
@Command annotation can be placed on a class which either defines defaults or shared settings
for @Command methods defined in a same class. In below example a command parent example is
defined.
Unresolved include directive in modules/ROOT/pages/commands/registration/annotation.adoc - include::../../test/java/org/springframework/shell/docs/CommandAnnotationSnippets.java[]使用 @Command 不会自动注册命令目标，而是需要使用 @EnableCommand 和/或 @CommandScan 注解。此模型与 Spring 伞形组织的其他部分的模型类似，并且为用户提供了更好的灵活性，对命令目标而言是包容性的，而不是排他性的。
Using a @Command will not automatically register command targets, instead it is required to use
@EnableCommand and/or @CommandScan annotations. This model is familiar from other parts
of Spring umbrella and provides better flexibility for a user being inclusive rather than exclusive
for command targets.
你可以使用 @EnableCommand 来定义目标类。它可以从所有 Configuration 类中提取。
You can define target classes using @EnableCommand. It will get picked from all Configuration
classes.
