包路径：org.springframework.web.context.support.WebApplicationObjectSupport
类名称：WebApplicationObjectSupport
方法名：isContextRequired

WebApplicationObjectSupport.isContextRequired介绍

[英]Overrides the base class behavior to enforce running in an ApplicationContext. All accessors will throw IllegalStateException if not running in a context.
[中]重写基类行为以强制在ApplicationContext中运行。如果没有在上下文中运行，所有访问器都将抛出IllegalStateException。
