class StubWebApplicationContext extends java.lang.Object implements WebApplicationContext
As registered object instances are instantiated and initialized externally,
there is no wiring, bean initialization, lifecycle events, as well as no
pre-processing and post-processing hooks typically associated with beans
managed by an ApplicationContext
. Just a simple lookup into a
StaticListableBeanFactory
.

BeanFactory
This method allows a Spring BeanFactory to be used as a replacement for the Singleton or Prototype design pattern. Callers may retain references to returned objects in the case of Singleton beans.
Translates aliases back to the corresponding canonical bean name. Will ask the parent factory if the bean cannot be found in this factory instance.

BeanFactory
Behaves the same as BeanFactory.getBean(String)
, but provides a measure of type
safety by throwing a BeanNotOfRequiredTypeException if the bean is not of the
required type. This means that ClassCastException can't be thrown on casting
the result correctly, as can happen with BeanFactory.getBean(String)
.

public boolean containsBean(java.lang.String name)
BeanFactory
If the given name is an alias, it will be translated back to the corresponding canonical bean name.
If this factory is hierarchical, will ask any parent factory if the bean cannot be found in this factory instance.
If a bean definition or singleton instance matching the given name is found,
this method will return true
whether the named bean definition is concrete
or abstract, lazy or eager, in scope or not. Therefore, note that a true
return value from this method does not necessarily indicate that BeanFactory.getBean(java.lang.String)
will be able to obtain an instance for the same name.

ResourceLoader
The handle should always be a reusable resource descriptor,
allowing for multiple InputStreamSource.getInputStream()
calls.
Note that a Resource handle does not imply an existing resource;
you need to invoke Resource.exists()
to check for existence.
